Resolution 2020-008
NOW, THEREFORE, BE IT RESOLVED that the Planning Commission of the City
of Rohnert Park makes the following findings, determinations and recommendations with respect
to the proposed revisions to Sections 17.04.030 – Definitions of words and terms, 17.07.020 –
Footnotes, 17.10.060 – Accessory structures, 17.16.040 – Parking exemptions of the Rohnert
Park Municipal Code for the purpose of conforming to recently amended state law:
Section 1. The above recitations are true and correct.
Section 2. Findings. The Planning Commission hereby makes the following findings
concerning Sections 17.04.030 – Definitions of words and terms, 17.07.020 – Footnotes,
17.10.060 – Accessory structures, and 17.16.0404 – Parking exemptions of the Municipal
Code:
1. That the proposed amendments to the Municipal Code are consistent with the
General Plan 2020.
Criteria Satisfied. The new state law included in Government Code 65852.2,
explicitly states that accessory dwelling unit conforming to state standards shall, by
law, be deemed to be a residential use that is consistent with the existing general plan
and zoning designations for the lot, and shall not be considered to exceed the
allowable density for the lot upon which it is located.
In addition to this state declaration, the proposed amendments to the Municipal Code
are consistent with the General Plan 2020 Goals of maintaining a compact urban
form, and providing a range of housing types and prices. Specifically, Goal LU-A
(compact urban form) is promoted by a more efficient utilization of land, housing
stock, and infrastructure. Goal CD-H (variety of housing types and sizes) is promoted
by allowing smaller units in well-established neighborhoods. Goal HO-2 (diversity of
housing types) is promoted by the allowance for smaller residences. Goal HO-3
(affordable housing) is encouraged by allowing smaller accessory units.
2. That the proposed amendment to the Zoning Ordinance will be beneficial to the
public health, safety or welfare.
Criteria Satisfied. The proposed amendments to the municipal code are intended to
address public health, safety and welfare concerns created by the statewide housing
crisis. The changes will help improve community health outcomes, by reducing
overcrowding, providing additional workforce housing closer to job center and
reducing homelessness by expanding the availability of rental units. In addition, the
minimum standards for setback, unit size, and unit design ensure that ADUs
constructed in compliance with the municipal code will provide residents with safe
and habitat living space.
Section 3. Environmental Clearance.
The ordinance and amendments are statutorily exempt from CEQA under Public
Resources Code Section 21080.17, which exempts adoption of an ordinance to
implement regulations for accessory dwelling units pursuant to Government Code
Section 65852.2.
NOW, THEREFORE, BE IT FURTHER RESOLVED that the Planning Commission
does hereby recommend that the City Council adopt the proposed amendments to RPMC
Sections 17.04.030 - Definitions of words and terms, 17.07.020 -Footnotes, 17.10.060 -
Accessory structures, 17.16.040 - Parking exemptions in the form provided in Exhibit A,
subject to minor changes approved the City Attorney or City Manager.
DULY AND REGULARLY ADOPTED on this 23 rd day of July, 2020 by the City of
Rohnert Park Planning Commission by the following vote:

family residential uses, including mixed-use zones, subject to the requirements of this
subsection.
2. ADUs or JADUs shall not be sold separately from the primary structure on the lot nor shall any
subdivision of the land separating the ADU or JADU and the primary structure be permitted by
the City.
3. The application for an ADU or JADU shall be considered ministerially without discretionary
review or a hearing within 60 days after receiving the application if there is an existing single
family or multi-family dwelling on the lot. If the application for the ADU or JADU is proposed in
conjunction with an application for a new single-family dwelling or multi-family dwelling, the
application will be processed with the application for the main dwelling unit(s).
4. General Design Requirements
The following standards shall apply:
a. The ADU or JADU shall be designed to be architecturally compatible with the primary

7. Additional Requirements for Junior Accessory Dwelling Units
a. The maximum square footage of a JADU shall be no more than 500 square feet, and a

relation to the size of the dwelling unit.
e. Owner occupancy shall be required for each JADU. The owner shall reside either in the
primary dwelling unit or the newly created JADU. Owner-occupancy shall not be
required if the owner is another governmental agency, land trust, or housing
organization.
f. Each JADU shall be subject to a deed restriction, in a form approved by the City, with
provisions specifying that:
i. Owner occupancy of either primary dwelling or JADU shall be required.

spaces.
9. Capacity, Connection and Impact Fees
a. Except for the case where an ADU or JADU is constructed within an existing single
family dwelling unit in accordance with Chapter 17.07.20.X (5)(a), a new, separate or
upgraded utility connection may be required between the primary residence/ADU and
the public water or sewer utility if site specific conditions necessitate a new
connection in order to provide minimum levels of utility service. Connection fee or
Exhibit A to Resolution
5
capacity charges may be calculated proportionate to the burden of the proposed ADU
based upon either its square feet, the number of its drainage fixture unit (DFU) values,
as defined in the Uniform Plumbing Code adopted and published by the International
Association of Plumbing and Mechanical Officials, or any other method that
reasonably estimates the proportional impact of the ADU.
b. For the purposes of providing services for water, sewer, or power, including a
connection fee, a JADU shall not be considered a separate or new dwelling unit. An ADU
shall not be considered a new residential use for purposes of calculating connection fees
or capacity charges for utilities, including water and sewer service, unless the ADU is
constructed with a new single-family dwelling.
c. No impact fee shall be assessed upon the development of an ADU less than 750 square
feet or any JADU, and impact fees charged for an accessory dwelling unit of 750 square
feet or more shall be charged proportionately in relation to the square footage of the
primary dwelling unit.
10. Before obtaining a certificate of occupancy for an ADU or JADU the applicant shall:
a. Demonstrate adequate water and sewer service available to serve the ADU or JADU,
as determined by the city engineer.

of a building standard pertaining to an ADU or JADU shall comply with Section 17980.12 of the
Health and Safety Code.

17.10.060 - Accessory structures.
A. For Accessory Dwelling Units, see RPMC 17.07.020(X). For the purposes of this section, an
accessory structure does not include an Accessory Dwelling Unit or Junior Accessory Dwelling Unit.
B. Detached/Attached. Detached accessory structures (i.e. structures separated from the main
structure by five feet or more) shall be located behind the front elevation of the main structure and
shall cover no more than ten percent of the rear yard area (unless an accessory dwelling unit), with
total lot coverage for all structures on-site not to exceed that listed in Section 17.10.020 for the
applicable zoning district. In the event an accessory building is attached to the main building or less
than five feet from the main structure, it shall be considered structurally a part of the main building
and shall comply in all respects with the development standards applicable to the main building.
C. Setbacks for Accessory Structures. The minimum side and rear yard setback for carports is five
feet and for all other accessory structures the setback is three feet.
D. Building Permits Requirements. Building permits are not required for detached accessory
structures that are one hundred twenty-eight square feet or less in size, that are no greater than

17.16.040 - Parking exemptions.
A. A reduction of up to twenty-five percent of the spaces required for a combination of uses may be
allowed where findings are made indicating that the uses share a common parking area and the
demand for parking occurs over different time periods, thereby making the full requirement
unnecessary.
B. Parking space reductions of up to ten percent may be permitted by the planning manager or
designee, if a rideshare, transit incentive program, or other transportation system management
program is provided. Further parking space reductions up to a maximum of twenty-five percent may
be permitted if approved by the planning commission through issuance of a conditional use permit.
C. Garage Conversions to Create Additional Room in a Single-Family Property. The planning manager
may grant exemptions to the off-street covered parking requirements for a single-family residential
property subject to the granting of an administrative permit, in accord with the provisions of Section
17.25 Article V if the following findings can be made:
1. The principal use of the lot is an existing single-family residence;
2. The garage conversion shall require that the resulting eliminated off-street covered
parking be replaced with one non-tandem parking space per lot, other than those existing in
the driveway;
3. Such replacement space may be located in the required front yard or street side yard if the
planning manager finds that in so doing there is neither an appreciable impairment of
pedestrian safety nor any reduction in the attractiveness of the neighborhood. In no case
shall the replacement space cause more than fifty percent of the lot's front yard to be
devoted to parking;
4. Such replacement space shall not be rented;
5. Such replacement space shall be paved with an approved, all-weather surface;
6. The provision and maintenance of such replacement space shall be the continuing
obligation of the property owner;
7. No more than one additional room, exclusive of closets and similar appurtenant spaces,
shall be created by a garage conversion;
8. The garage door shall remain in place and look functional; and
9. The lot must be a minimum width of fifty feet and there must be room for at least one on-
street parking space on the curb in front of the lot.
D. If an existing parking lot does not provide adequate parking spaces for the disabled and cannot
otherwise be reconfigured to achieve the city's required inventory of parking spaces, the planning
and community development director may approve a reduction in the number of parking spaces by
up to a maximum of three parking spaces or a total of ten percent, whichever is less, in order to
accommodate required disabled parking.
