ADUs offer benefits that address common development barriers such as affordability and environmental quality.
ADUs are an affordable type of home to construct in California because they do not require paying for land, major
new infrastructure, structured parking, or elevators. ADUs are built with cost-effective one- or two-story wood frame
construction, which is significantly less costly than homes in new multifamily infill buildings. ADUs can provide as
much living space as the new apartments and condominiums being built in new infill buildings and serve very well
for couples, small families, friends, young people, and seniors.
ADUs are a different form of housing that can help California meet its diverse housing needs, Young professionals
and students desire to live in areas close to jobs, amenities, and schools. The problem with high -opportunity areas
is that space is limited. There is a shortage of affordable units and the units that are available can be out of reach
for many people. To address the needs of individuals or small families seeking living quarters in high opportunity
areas, homeowners can construct an ADU on their lot or convert an underutilized part of their home like a garage
into a junior ADU. This flexibility benefits not just people renting the space, but the homeowner as well, who can
receive an extra monthly rent income.
ADUs give homeowners the flexibility to share independent living areas with family members and others, allowing
seniors to age in place as they require more care and helping extended families to be near one another while
maintaining privacy.
Relaxed regulations and the cost to build an ADU make it a very feasible affordable housing option. A LIC Berkeley
study noted that one unit of affordable housing in the Day Area costs about $500,000 to develop whereas an ADU
can range anywhere up to $200,000 on the expensive end in high housing cost areas:
ADUs are a critical form of infill -development that can be affordable and offer important housing choices within
existing neighborhoods. ADUs are a powerful type of housing unit because they allow for different uses, and serve
different populations ranging from students and young professionals to young families, people with disabilities and
senior citizens. By design, ADUs are more affordable and can provide additional income to homeowners, local
governments can encourage the development of ADUs and improve access to jobs, education and services for
many Californians.
Fees
SB 1069 provides that ADUs shall not be considered new residential uses for the purpose of calculating utility
connection fees or capacity charges; including water and sewer service. The bill prohibits a local agency from
requiring an ADL1 applicant to install a new or separate utility connection or impose a related connection fee or
capacity charge for ADUs are contained within an existing residence or accessory structure, For attached and
detached ADUs, this fee or charge must be proportionate to the burden of the unit on the water or sewer system
and may not exceed the reasonable cost of providing the service:
Fire . Requirements
SB 1069 provides that fire sprinklers shall not be required in an accessory unit if they are not required in the
primary residence°
ADUs within iti
Local governments must ministerially approve an application to create within a single family residential zone one
ADL1 per single family loft if the unit is:
• contained within an existing residence or accessary structure.
• has independent exterior access from the existing residence.
• has side and rear setbacks that are sufficient for fire safety:
These provisions apply within all single family residential zones and ADUs within existing space must be allowed in
all of these zones. No additional parking or other development standards can be applied except for building code
requirements.
No Total Prohibition
SB 1069 prohibits a local government from adopting an ordinance that precludes ADUs.
Generally, AS 2299 (Chapter 735, Statutes of 2016) requires a local government (beginning January 1, 2017) to
ministerially approve ADUs if the unit complies with certain parking requirements, the maximum allowable size of
an attached ADU, and setback requirements, as follows:
• The unit is not intended for sale separate from the primary residence and maybe rented.
• The lot is Maned for single-family or multifamily use and contains an existing, single-family dwelling.
• The unit is either attached to an existing dwelling or located within the living area of the existing dwelling or
detached and on the same lot.
• The increased floor area of the unit does not exceed 50% of the existing living area, with a maximum
increase in floor area of 1,200 square feet,
• The total area of floorspace for a detached accessory dwelling unit does not exceed 1,200 square feet.
• No passageway can be required.
• No setback can be required from an existing garage that is converted to an ADU.
• Compliance with local building code requirements.
• Approval by the local health officer where private sewage disposal system is being used.
Impact on ExistingAccessory elli nit Ordinances
AS 2299 provides that any existing ADU ordinance that does not meet the bill's requirements is null and void upon
the date the bill becomes effective. In such cases, a jurisdiction must approve accessory dwelling units based on
Government Code Section 65852.2 until the jurisdiction adopts a compliant ordinance.
AB 2240E,;
AS 2406 (Chapter 7554 Statutes of 2016) creates more flexibility for housing options by authorizing local
governments to permit junior accessory dwelling units (JADU) through an ordinances The bill defines JADUs to be
a unit that cannot exceed 500 square feet and must be completely contained within the space of an existing
residential structure. in addition, the bill requires specified components for a local JADU ordinance. Adoption of a
JADU ordinance is optional.
Required nents
The ordinance authorized by AS 2406 must include the following requirements;
• Limit to one JADU per residential lot zoned for single-family residences with a single-family residence already
built on the lot:
m The single-family residence in which the JADU is created or JADU must be occupied by the owner of the
residence.
• The owner must record a deed restriction stating that the JADU cannot be sold separately from the single-
family residence and restricting the JADU to the size limitations and other requirements of the JADU
ordinance.
• The JADU must be located entirely within the existing structure of the single-family residence and JADU have
its own separate entrance.
• The JADU must include an efficiency kitchen which includes a sink, cooking appliance, counter surface, and
storage cabinets that meet minimum building code standards. No gas or 220V circuits are allowed.
a The JADU may share a bath with the primary residence or have its own bath.
Prohibited _ n,rpt
This bill prohibits a local JADU ordinance from requiring;
• Additional parking as a condition to grant a permit:
• Applying additional water, sewer and power connection fees. No connections are needed as these utilities
have already been accounted for in the original permit for the home.
5
Fire Safety Requirements
AS 2406 clarifies that a JADU is to be considered part of the single-family residence for the purposes of fire and
life protections ordinances and regulations, such as sprinklers and smoke detectors. The bill also requires life and
protection ordinances that affect single-family residences to be applied uniformly to all single-family residences,
regardless of the presence of a JADU.
As part of the housing element portion of their general plan, local governments are required to identify sites with
appropriate zoning that will accommodate projected housing needs in their regional housing need allocation
(RHNA) and report on their progress pursuant to Government Code Section 65400. To credit a JADU toward the
RHNA, HCD and the Department of Finance (DOF) utilize the census definition of a housing unit which is fairly
flexible. Local government count units as part of reporting to DOF. JADUs meet these definitions and this bill
would allow cities and counties to earn credit toward meeting their RHNA allocations by permitting residents to
create less costly accessory units. See additional discussion under JADU frequently asked questions,

Frequently Asked Questions:
Accessory Dwelling Units
Yes, ADU law and recent changes intend to address barriers, streamline approval and expand potential capacity
for ells recognizing their unique importance in addressing California's housing needs. The preparation, adoption,
amendment and implementation of local ADU ordinances must be carried out consistent with Government Code
Section 65852.150:
(a) The Legislature finds and declares ,all of the following.
(1) Accessory dwelling units are a valuable form of housing in California.
() Accessory dwelling units provide housing for family members, students, the elderly, in-home health care
providers, the disabled, and others; at below market prices within existing neighborhoods.
(3) Homeowners who create accessory dwelling units benefit from added income, and an increased sense of
security.
(4) Allowing accessory dwelling units in single -family or multifamily residential zones provides additional rental
housing stock in California.
(5) California faces a severe housing crisis.
(6) The state is falling far short of meeting current and future housing demand with serious consequences for
the state's economy, our ability to build green infill consistent with state greenhouse gas reduction goals, and
the well-being of our citizens, particularly tower and middle-income earners.
(7) Accessory dwelling units offer lower cost housing to meet the needs of existing and future residents within
existing neighborhoods, while respecting architectural character.
(8) Accessory dwelling units are, therefore, an essential component of Californias housing supply.
(b) It is the intent of the Legislature that an accessory dwelling unit ordinance adopted by a local agency has
the effect of providing for the creation of accessory dwelling units and that provisions in this ordinance relating
to matters including unit size, parking, fees, and other requirements, are not so arbitrary, excessive, or
burdensome so as to unreasonably restrict the ability of homeowners to create accessory dwelling units in
zones in which they are authorized by local ordinance.
7
.Are E-xisung Ondirianc,es NO and Vold'?
Yes, any local ordinance adopted prior to January 1, 2017
that is not in compliance with the changes to ADU law will be
null and void. Until an ordinance is adopted, local
governments must apply "state standards" (See Attachment
4 for State Standards checklist). In the absence of a local
ordinance complying with ADU law, local review must be
limited to "state standards" and cannot include additional
requirements such as those in an existing ordinance.
Are Local Goverrirmcat-fl,.c, FZ�,eq u� i red to Adop,
L
an Ordinance?
No, a local government is not required to adopt an ordinance. ADUs built within a jurisdiction that lacks a local
ordinance must comply with state standards (See Attachment 4). Adopting an ordinance can occur through
different forms such as a new ordinance, amendment to an existing ordinance, separate section or special
regulations within the zoning code or integrated into the zoning code by district. However, the ordinance should be
established legislatively through a public process and meeting and not through internal administrative actions such
as memos or zoning interpretations.
Can, a Local Governmient Preclude ADIL)s?
No local government cannot preclude ADUs.
Can a Local Govern ,,nent Appty Development Standards and Designate Areas?
Yes, local governments may apply development standards and may designate where ADUs are permitted (GC
Sections 65852.2(a)(1)(A) and (13)). However, ADUs within existing structures must be allowed in all single family
residential zones,
For ADUs that require an addition or a new accessory structure, development standards such as parking, height,
lot coverage, lot size and maximum unit size can be established with certain limitations, ADUs can be avoided or
allowed through an ancillary and separate discretionary process in areas with health and safety risks such as high
fire hazard areas, However, standards and allowable areas must not be designed or applied in a manner that
burdens the development of ADUs and should maximize the potential for ADU development. Designating areas
where ADUs are allowed should be approached primarily on health and safety issues including water, sewer, traffic
flow and public safety. Utilizing approaches such as restrictive overlays, limiting ADUs to larger lot sizes,
burdensome lot coverage and setbacks and particularly concentration or distance requirements (e.g., no less than
500 feet between ADUs) may unreasonably restrict the ability of the homeowners to create ADUs, contrary to the
intent of the Legislature.

maximum unit size, maximum lot coverage, minimum setbacks, architectural and landscape requirements)
that allows ADUs to fit well within the built environment.
a Local Governm�ent Adopt `t e tea, Restrictive ReqUireirrients?
Yes, ADU law is a minimum requirement and its purpose is to encourage the development of ADUs. 'Local
governments can take a variety of actions beyond the statute that promote ADUs such as reductions in fees, less
restrictive parking or unit sizes or amending general plan policies.
develo mani! ro 'ramsladcessor-dwellin -unit-develn ment- ro ram.
Car - Local Governments Est ablish i�x in mi.nrn and Ma iiou Ur' Size
Yes, a local government may establish minimum and maximum unit sizes (GC Section 65852.2(c). However, like
all development standards (e.g., height, lot coverage, lot size), unit sizes should not burden the development of
ADUs. For example, setting a minimum unit size that substantially increases costs or a maximum unit size that
unreasonably restricts opportunities would be inconsistent with the intent of the statute. Typical maximum unit
sizes range from 5170 square feet to 1,200 square feet. Minimum unit size must at least allow for an efficiency unit
as defined in Health and Safety Code Section 17955.1.
ADU law requires local government approval if meeting various requirements (GC Section
65852.2(a)(1)(D)), Including unit size requirements. Specifically, attached ADUs shall not exceed 50
percent of the existing living area or 1,200 square feet and detached ADUs shall not exceed 1,200
square feet. A local government may choose a maximum unit size less than 1,200 square feet as long
s the requirement is not burdensome on the creation of ADUs.
—
An ACLU is an accessory use for the purposes of calculating allowable density under the general plan and zoning.
For example, if a zoning district allows one unit per 7,500 square feet, then an ACM would not be counted as an
additional unit. Minimum lot sizes must not be doubled (e.g,, 15,000 square feet) to account for an ADU. Further,
local governments could elect to allow more than one ADU on a lot.
supply concurrent with the availability of marKet rate housing.
How Are Fees Charged to ADUs?
All impact fees, including water, sewer, park and traffic fees must be charged in accordance with the Fee Mitigation
Act, which requires fees to be proportional to the actual impact (e.g., significantly less than a single family home).
Fees on ADUs, must proportionately account for impact on services based on the size of the ADU or number of
plumbing fixtures. For example, a 700 square foot new ADU with one bathroom that results in less landscaping
should be charged much less than a 2,000 square foot home with three bathrooms and an entirely new
landscaped parcel which must be irrigated. Fees for ADUs should be significantly less and should account for a
lesser impact such as lower sewer or traffic impacts.
What Ublity Fee ReqLflire.!"Tients Appiy to ADUs?
Cities and counties cannot consider ADUs as new residential uses when calculating connection fees and capacity
charges,
Where ADUs are being created within an existing structure (primary or accessory), the city or county cannot
require a new or separate utility connections for the ADLI and cannot charge any connection fee or capacity
charge.
For other ADUs, a local agency may require separate utility connections between the primary dwelling and the
ADU, but any connection fee or capacity charge must be proportionate to the impact of the ADU based on either its
size or the number of plumbing fixtures.
What Utility Fee Reqt,.flrenr�ents App�y to Non -City and CmAHnt,,,v Su.,� vice Districts?
All local agencies must charge impact fees in accordance with the Mitigation Fee Act (commencing with
Government Code Section 66000), including in particular Section 66013, which requires the connection fees and
capacity charges to be proportionate to the burden posed by the ADU. Special districts and non -city and county
service districts must account for the lesser impact related to an ADU and should base fees on unit size or number
of plumbing fixtures. Providers should consider a proportionate or sliding scale fee structures that address the
smaller size and lesser impact of ADUs (e.g., fees per square foot or fees per fixture). Fee waivers or deferrals
could be considered to better promote the development of ADUs.
Do Utility Fee Requirerrents Apply to ADUs within Existing Space"?
No, where ADUs are being created within an existing structure (primary or accessory), new or separate utility
connections and fees (connection and capacity) must not be required.
Does "Public 'Transit" 1� ),clude within Orfof a Bus Stop al nd Train
Station?
Yes, "public transit" may include a bus stop, train station and paratransit if appropriate'for the applicant, "Public
transit" includes areas where transit is available and can be considered regardless of tighter headways (e,g., 15
minute intervals). Local governments could consider a broader definition of "public transit" such as distance to a
bus route.

No, ADU law does not allow parking to be required when there is a car share located within a block of the ADU. A
car share location includes a designated pick up and drop off location. Local governments can measure a block
from a pick up and drop off location and can decide to adopt broader distance requirements such as two to three
blocks.
Is Off ei Parking

rc
Yes, ADU law deliberately reduces parking requirements. Local governments may make specific findings that
tandem parking and parking in setbacks are infeasible based on specific site, regional topographical or fire and life
safety conditions or that tandem parking or parking in setbacks is not permitted anywhere else in the jurisdiction.
However, these determinations should be applied in a manner that does not unnecessarily restrict the creation of
ADUs;
Local governments must provide reasonable accommodation to persons with disabilities to promote equal
access horsing and comply with fair housing laws and housing element law. The reasonable
accommodation procedure must: provide exception to zoning and land use regulations which includes an
ADU ordinance. Potential exceptions are not limited and may include development standards such a
setbacks and parking requirements and permitted uses that further the housing opportunities of individuals
with disabilities.
Is Coven' -"",d Parking ReqLflre,,'J?
No, off street parking must be permitted through tandem parking on an existing driveway, unless specific findings
are made.

l�a .`��n, :: � �� t����rg n s
Yes, but only if the local government requires off-street parking to be replaced in which case flexible arrangements
such as tandem, including existing driveways and uncovered parking are allowed. Local governments have an
opportunity to be flexible and promote ADUs that are being created on existing parking space and can consider not
requiring replacement parking.
Are Setbacks ReqUired When ars Existing arag e Is Curiv rte to an ADU?
No, setbacks must not be required when a'garage is converted or when existing space (e.., game room or office)
above a garage is converted. Rear and side yard setbacks of no more than five feet are required when new space
is added above a garage for an ADU. In this case, the setbacks only apply to the added space above the garage,
not the existing garage and the ADU can be constructed wholly or partly above the garage, including extending
beyond the garage walls.
Also, when a garage, carport or covered parking structure is demolished or where the parking area ceases to exist
so an ADU can be created, the replacement parking must be allowed in any "configuration" can the lest, "...including;
but not limited to, covered spaces, uncovered spaces, or tandem spaces, or...." Configuration can be applied in a
flexible manner to not burden the creation of ADUs. For example, spatial configurations like tandem on existing
driveways in setback areas or not requiring excessive distances from the street would be appropriate:
e, ADI ki Per-mittt,--,d in Existing Residence or Accessory S"pace?
Yes, ADUs located in single family residential zones and existing space of a single family residence or accessory
structure must be approved regardless of zoning standards (Section 65652:2(a)(1)(B)) for ADUs, including
locational requirements (Section 65652.2(a)(1)(A)), subject to usual non -appealable ministerial building permit
requirements. For example, ADUs in existing space does not necessitate a zoning clearance and must not be
limited to certain zones or areas or subject to height, lot sizes loft coverage, unit size, architectural review,
landscape or parking requirements. Simply, where a single family residence or accessory structure exists in any
single family residential zone, so can an ADU. The purpose is to streamline and expand potential for ADUs where
impact is minimal and the existing footprint is not being Increased.
Zoning requirements are not a basis for denying a ministerial building permit for an ADU, including non -conforming
lots or structures. The phrase, "..within the existing space includes areas within a primary home or within an
attached or detached accessory structure such as a garage, a carriage house, a pool house, a rear yard studio
and similar enclosed structures.
Are Owner, Occupants Required?
No, however, a local government can require an applicant to be an owner occupant. The owner may reside in the
primary or accessory structure. Local governments can also require the ADU to not be used for short term rentals
(terms lesser than 60 days): Both owner occupant use and prohibition on short term rentals can be required on the
same property. Local agencies which impose this requirement should require recordation of a deed restriction
regarding owner occupancy to comply with GC Section 27261 e5
.�,`,prinklers Required for ADLJs?
Depends, ADUs shall not be required to provide fire sprinklers if they are not or were not required of the primary
residence. However, sprinklers can be required for an ADU if required in the primary structure: For example, if the
primary residence has sprinklers as'a result of an existing ordinance, then sprinklers could be required in the ADU.
Alternative methods for fire protection could be provided.
If the ADU is detached from the main structure or new space above a detached garage, applicants can be
encouraged to contact the local fire jurisdiction for information regarding fire sprinklers. Since ADUs are a unique
opportunity to address a variety of housing needs and provide affordable housing options for family members,
students, the elderly, in-home health care providers, the disabled, and others, the fire departments want to ensure
the safety of these populations as well as the safety of those living in the primary structure. Fire Departments can
help educate property owners on the benefits of sprinklers, potential resources and how they can be installed cost
effectively. For example, insurance rates are typically 5 to 10 percent lower where the unit is sprinklered. -Finally,
other methods exist to provide additional fire protection. Some options may include additional exits, emergency
escape and rescue ripenings, 1 "hour or greater fire -rated assemblies, roofing materials and setbacks from property
lines or other structures.

Z> 14 cz, � U I c"I U L U � uk"i I R:,� E,;, t x. 3 e d a s a n, A D U ?
Yes, an ADU is any residential dwelling unit with independent facilities and permanent provisions for living,
sleeping, eating, cooking and sanitation. An ADU includes an efficiency unit (Health and Safety Code Section
17958.1) and a manufactured home (Health and Safety Code Section 18007).
Can -,,in Efficiency Unit Be Smaller than 220 Squwe Feet?
Yes, an efficiency unit for occupancy by no more than two persons, by statute (Health and Safety Code Section
17958,11), can have a minimum floor area of 150 square feet and can also have partial kitchen or bathroom
facilities, as specified by ordinance or can have the same meaning specified in the Uniform Building Code,
referenced in the Title 24 of the California Code of Regulations.
Does ADItJ Apply Ito CI�iarte,r Cide,s and Cuunfles?
Yes. ADU law explicitly applies to "local agencies" which are defined as a city, county, or city and county whether
general law or chartered (Section 65852.2(i)(2)).

Yes, ADU ordinances must be submitted to the State Department of Housing and Community Development within
0 days after adoption, including amendments to existing ordinances. However, upon submittal, the ordinance is
not subject to a Department review and findings process similar to housing element law (GC Section 65565)

,e iq� a{ l JADLI l m °.3 li d:�$:? b r
JADUs offer the simplest and most affordable housing option. They bridge the gap between a roommate and a
tenant by offering an interior connection between the unit and main living area. The doors between the two spaces
can be secured from both sides, allowing them to be easily privatized or incorporated back into the main living
area. These units share central systems, require no fire separation, and have a basic kitchen, utilizing small plug
in appliances,reducing development costs. This provides flexibility and an insurance policy in homes in case
additional income or housing is needed, They present no additional stress on utility services or infrastructure
because they simply repurpose spare bedrooms that do not expand the homes planned occupancy. No additional
address is required on the property because an interior connection remains. By adopting a JADU ordinance, local
governments can offer homeowners additional options to take advantage of underutilized space and better
address its housing needs.
Can JADUs COUnttowards the RHNA?
Yes, as part of the housing element portion of their general plan, local governments are required to identify sites
with appropriate zoning that will accommodate projected housing needs in their regional housing need allocation
(REINA) and report on their progress pursuant to Government Code Section 65400. To credit a unit toward the
REINA, EICD and the Department of Finance (D F) utilize the census definition of a housing unit. Generally, a
JADU, including with shared sanitation facilities, that meets the census definition and is reported to the Department
of Finance as part of the DGF annual City and County Housing Unit Change Survey can be credited toward the
RHNA based on the appropriate income level. Local governments can track actual or anticipated affordability to
assure the JADU is counted to the appropriate' income category.For example, some local governments request
and track information such as anticipated affordability as part of the building permit application.

No, JADUs shall not be considered a separate or new dwelling unit for the purposes of fees and as a result should
not be charged a fee for providing water, sewer or power, including a connection fee, These requirements apply to
all providers of water, sewer and power, including non -municipal providers.
Local governments may adopt requirements for fees related to parking, other service or connection for water,
sewer or power, however, these requirements must be uniform for all single family residences and JADUs are not
considered a new or separate unit:

Yes, a local government may adopt requirements related to fire and life protection requirements. However, a JADU
shall not be considered a new or separate unit. In other words, if the primary unit is not subject to fire or life
protection requirements, then the JADU must be treated the same.

Draft Junior Accessory Dwelling Units (JADU) - Flexible Housing
Findings:
1 , Causation: Critical need for housing for lower income families and individuals given the high cost of living and
low supply of affordable homes for rent or purchase, and the difficulty, given the current social and economic
environment, in building more affordable housing
2. Mitigation: Create a simple and inexpensive permitting track for the development of junior accessory dwelling
units that allows spare bedrooms in homes to serve as a flexible form of infill housing
3. Endangerment: Provisions currently required under agency ordinances are so arbitrary, excessive, or
burdensome as to restrict the ability of homeowners to legally develop these units therefore encouraging
homeowners to bypass safety standards and procedures that make the creation of these units a benefit to the
whole of the community
4, Co -Benefits: Homeowners (particularly retired seniors and young families, groups that tend to have the lowest
incomes) - generating extra revenue, allowing people facing unexpected financial obstacles to remain in their
homes, housing parents, children or caregivers; Homebuyers - providing rental income which aids in mortgage
qualification under new government guidelines; Renters - creating more low-cost housing options in the
community where they work, go to school or have family, also reducing commute time and expenses;
Municipalities - helping to meet RHNA goals, increasing property and sales tax revenue, insuring safety
standard code compliance, providing an abundant source of affordable housing with no additional
infrastructure needed; Community - housing vital workers, decreasing traffic, creating economic growth both in
the remodeling sector and new customers for local businesses; Planet - reducing carbon emissions, using
resources more efficiently;
5. Benefits of Junior ADUs: offer a more affordable housing option to both homeowners and renters, creating
economically healthy, diverse, multi -generational communities;
Therefore the following ordinance is hereby enacted:
This Section provides standards for the establishment of junior accessory dwelling units, an alternative to the
standard accessory dwelling unit, permitted as set forth under State Law AB 1866 (Chapter 1062, Statutes of
2002) Sections 65852.150 and 65852.2 and subject to different provisions under fire safety codes based on the
fact that junior accessory dwelling units do not qualify as "complete independent living facilities" given that the
interior connection from the junior accessory dwelling unit to the main living area remains, therefore not redefining
the single-family home status of the dwelling unit.
A) Development Standards. Junior accessory dwelling units shall comply with the following standards, including
the standards in Table below:
1 ) Number of Units Allowed. Only one accessory dwelling unit or, junior accessory dwelling unit, may be
located on any residentially zoned lot that permits a single-family dwelling except as otherwise regulated or
restricted by an adopted Master Plan or Precise Development Plan. A junior accessory dwelling unit may
only be located on a lot which already contains one legal single-family dwelling.
2) Owner Occupancy: The owner of a parcel proposed for a junior accessory dwelling unit shall occupy as a
principal residence either the primary dwelling or the accessory dwelling, except when the home is held by
an agency such as a land trust or housing organization in an effort to create affordable housing.
3) Sale Prohibited., A junior accessory dwelling unit shall not be sold independently of the primary dwelling on
the parcel.
29
) Deed Restriction: A deed restriction shall be completed and recorded, in compliance with Section B below.
5) Location of Junior Accessary Dwelling Unit: A junior accessory dwelling unit must be created within the
existing walls of an existing primary dwelling, and must include conversion of an existing bedroom.
6) Separate Entry Required. A'separate exterior entry shall be provided to serve a junior accessory dwelling
unit.
7) Interior Entry Remains: The interior connection to the main living area must be maintained, but a second
door may be added for sound attenuation.
8) Kitchen Requirements: The junior accessory dwelling unit shall include an efficiency kitchen, requiring and
limited to the following components:
a) A sink with a maximum waste line diameter of one -acid -a -half (1.5) inches,
b) A cooking facility with appliance which do not require electrical service greater than one -hundred -and -
twenty (120) volts or natural or propane gas, and
c) A food preparation counter and storage cabinets that are reasonable to size of the unit.
9) Parking: No additional parking is required beyond that required when the existing primary dwelling was
constructed.
Development Standards for Junior Accessory Dwelling Unit -
B) Deed Restriction: Prior to obtaining a building permit for a junior accessory dwelling unit, a deed restriction,
approved by the City Attorney, shall be recorded with the County Recorder's office, which shall include the
pertinent restrictions and limitations of a junior accessory dwelling unit identified in this Section. Said deed
restriction shall run with the land, and shall be binding upon any future owners, heirs, or assigns. A copy of the
recorded deed restriction shall be filed with the Department stating that:
1) The junior accessory dwelling unit shall not be sold separately from the primary dwelling unit;
2) The junior accessory dwelling unit is restricted to the maximum size allowed per the development
standards,
3) The junior accessory dwelling unit shall be considered legal only so long as either the primary residence,
or the accessory dwelling unit, is occupied by the owner of record of the property, except when the home is
owned by an agency such as a land trust or housing organization in an effort to create affordable housing;
4) The restrictions shall be binding upon any successor in ownership of the property and lack of compliance
with this provision may result in legal action against the property owner, including revocation of any right to
maintain a junior accessory dwelling unit on the property.
C) No Water Connection Fees: No agency should require a water connection fee for the development of a junior
accessory dwelling unit. An inspection fee to confirm that the dwelling unit complies with development standard
may be assessed.
D) No Sewer Connection Fees., No agency should require a sewer connection fee for the development of a junior
accessory dwelling unit. An inspection fee to confirm that the dwelling unit complies with development standard
30
may be assessed.
E) No Fire Sprinklers and Fire Attenuation: No agency should require fire sprinkler or fire attenuation
specifications for the development of a junior accessory dwelling unit. An inspection fee to confirm that the
dwelling unit complies with development standard may be assessed.

ACCESSORY DWELLING UNITS: CASE STUDY (26 pp.)
By United States Department of Housing and Urban Development, Office of Policy Development and Research.
(2008)
Introduction: Accessory dwelling units (ADUs) -- also referred to as accessory apartments, ADUs, or granny flats
-- are additional living quarters on single-family lots that are independent of the primary dwelling unit. The
separate living spaces are equipped with kitchen and bathroom facilities, and can be either attached or detached
from the main residence. This case study explores how the adoption of ordinances, with reduced regulatory
restrictions to encourage ADUs, can be advantageous for communities, Following an explanation of the various
types of ADUs and their benefits, this case study provides examples of municipalities with successful ADU
legislation and programs. Section titles include, History of ADUs; Types of Accessory Dwelling Units; Benefits of
Accessory Dwelling Units; and Examples of ADU Ordinances and Programs:

This White Paper fills two gaps in the discussion regarding compact units. First; we provide a detailed analysis of
the regulatory and other challenges to developing both ADUs and micro -units, focusing on five cities: New York;
Washington, DC; Austin; Denver; and Seattle. That analysis will be helpful not only to the specific jurisdictions we
study, but also can serve as a model for those who what to catalogue regulations that might get in the way of the
development of compact units in their own jurisdictions. Second, as more local governments permit or encourage
compact units, researchers will need to evaluate how well the units built serve the goals proponents claim they will.
SCALING UP SECONDARY UNIT PRODUCTION IN THE EAST BAY: IM acts and Folie Il�i�pllcations

This paper begins by analyzing how many secondary units of one particular type, detached backyard cottages,
might be built in the East Bay, focusing on the Flatlands portions of Berkeley, El Cerrito, and Oakland. We then
investigate the potential impacts of scaling up the strategy with regard to housing affordability, smart growth,
alternative transportation, the economy, and city budgets, A final section details policy recommendations, focusing
on regulatory reforms and other actions cities can take to encourage secondary unit construction, such as
promoting carsharing programs, educatingresidents, and providing access to finance.

SECONDARY KNITS AND URBAN INFILL: A literature Review -02

This literature review examines the research on both infill development in general„ and secondary units in
particular, with an eye towards understanding the similarities and differences between infill as it is more
traditionally understood — i.e., the development or redevelopment of entire parcels of land in an already urbanized
area—'and the incremental type of infill that secondary unit development constitutes,

This paper begins with a discussion of how to determine the development potential for :secondary units, and then
provides an overview of how many secondary units can be built in the East Bay of San Francisco Bay Area under
current regulations. The next two sections examine key regulatory barriers in detail for the five cities in the study
(Albany, Berkeley, EI Cerrito, Oakland, and Richmond), looking at lot size, setbacks, parking requirements; and
procedural barriers. A sensitivity analysis then determines how many units could be built were the regulations to be
relaxed.

This study examines two puzzles that must be solved in order to scale up a secondary unit strategy: first, how can
city regulations best enable their construction? And second, what is the market for secondary units? Because
parking is such an important issue, we also examine the potential for secondary unit residents to rely on alternative
transportation modes, particular car share programs. The study looks at five adjacent cities in the East Bay of the
San Francisco Bay Area (Figure 1) -- Oakland, Berkeley, Albany, Bl Cerrito, and Richmond -- focusing on the
areas within '12 mile of five Bay Area Rapid Transit (BART) stations,

"HIDDEN" DENSITY, THE POTENTIAL OF SMALL-SCALE INFILL DEVELOPMENT (2 pp.)
By }Caren Chapple (2011)
!JC Berkeley: IURC Policy Brief.
Library Call # D44 1:2 H53 2011
California's implementation of SB 375, the Sustainable Communities and Climate Protection Act of 2008, is putting
new pressure on communities to support infill development. As metropolitan planning organizations struggle to
communicate the need for density, they should take note of strategies that make increasing density an attractive
choice for neighborhoods and regions.

g[gAth stratecly_(22 pp.)
By Jake Wegmann and Karen Chapple. Journal of Urbanism 7(3): pp. 307-329. (2014)
Abstract (not available in full text): Secondary units, or separate small dwellings embedded within single-family
residential properties, constitute a frequently overlooked strategy for urban infill in high-cost metropolitan areas in
the United States. This study, which is situated within California's San Francisco Bay Area, draws upon data
collected from a homeowners' survey and a Rental Market Analysis to provide evidence that a scaled -up strategy
emphasizing one type of secondary unit — the backyard cottage -- could yield substantial infill growth with minimal
public subsidy. In addition, it is found that this strategy compares favorably in terms of affordability with infill of the
sort traditionally favored in the `smart growth' literature, i.e. the construction of dense multifamily housing
developments.
