18.08.080 - Two unit Senate Bill (SB) 9 project. ¶
The purpose of this section is to facilitate the development of new residential housing units consistent with the provisions of state law as reflected in Government Code Sections 65585, 65852.21, and 66411.7 et seq., and to establish an application and approval process for two unit SB 9 projects. In cases of conflict between this section and any other provision of this title, the provisions of this section shall prevail.
A.
A Two unit SB 9 project (meaning two attached or detached units on a property, as described further, below) shall be ministerially approved by staff if it meets all the following requirements:
1.
The parcel is located within the low-density residential (RL) or medium-density residential (RM) zoning district or in a Specific Plan on property intended for residential development.
2.
The parcel is not located in any of the following:
a.
Either prime farmland or farmland of statewide importance, as defined pursuant to United States Department of Agriculture land inventory and monitoring criteria, as modified for California, and designated on the maps prepared by the Farmland Mapping and Monitoring Program of the Department of Conservation, or land zoned or designated for agricultural protection or preservation by an approved local ballot measure.
b.
Wetlands, as defined in the United States Fish and Wildlife Service Manual, part 660 FW 2 (June 21, 1993).
c.
Within a very high fire hazard severity zone, as determined by the Department of Forestry and Fire Protection pursuant to Section 51178 of the Government Code, or within a high or very high fire hazard severity zone as indicated on maps adopted by the Department of Forestry and Fire Protection pursuant to Public Resources Code Section 4202. This subparagraph does not apply to sites excluded from the specified hazard zones by the city, pursuant to subdivision (b) of Section 51179 of the Government Code, or sites that have adopted fire hazard mitigation measures pursuant to existing building standards or state fire mitigation measures applicable to the development.
d.
A hazardous waste site that is listed pursuant to Government Code Section 65962.5 or a hazardous waste site designated by the Department of Toxic Substances Control pursuant to Heath and Safety Code Section 25356, unless the State Department of Public Health, State Water Resources Control Board, or Department of Toxic Substances Control has cleared the site for residential use or residential mixed uses.
e.

f.
Within a special flood hazard area subject to inundation by the 1 percent annual chance flood (100-year flood) as determined by the Federal Emergency Management Agency (FEMA) in any official maps published by FEMA. If a development proponent is able to satisfy all applicable federal qualifying criteria in order to provide that the site satisfied this subparagraph, the city shall not deny the application on the basis that the development proponent did not comply with any additional permit requirement, standard, or action adopted by the city that is applicable to that site. A development may be located on a site described in this subparagraph if either of the following are met (1) the site has been subject to a letter of map revision prepared by FEMA and issued to the city; or (2) the site meets FEMA requirements necessary to meet minimum flood plain management criteria of the National Flood Insurance Program pursuant to Part 59 (commencing with Section 59.1) and Part 60 (commencing with Section 60.1) of Subchapter B of Chapter 1 of Title 44 of the Code of Federal Regulations.
g.
Within a regulatory floodway as determined by FEMA in any official maps published by FEMA, unless the development has received a no-rise certification in accordance with Section 60.3(d)(3) of Title 44 of the
Code of Federal Regulations. If a development proponent is able to satisfy all applicable federal qualifying criteria in order to provide that the site satisfies this subparagraph and is otherwise eligible for streamlined approval under this section, the city shall not deny the application on the basis that the development proponent did not comply with any additional permit requirement, standard, or action adopted by the city that is applicable to that site.

j.
Lands under conservation easement.
3.
The two unit SB 9 project application would not require demolition or alteration of any of the following types of housing:

The parcel is not located within a historic district or property included on the State Historic Resources Inventory, as defined in Public Resources Code Section 5020.1, or within a site that is designated or listed as a city landmark or historic property or district by local ordinance.
6.
The two unit SB 9 project meets all other requirements of this section.
B.
A two unit SB 9 project shall be processed consistent with Section 18.76.020—Administrative site plan review required.
1.
Within 60 days of submittal of a complete application, the development services director (or his/her designee) shall review and approve complete applications that are in compliance with the requirements of this section and the underlying development standards in the zoning district or specific plan in which it is located, and any other applicable objective development standards stated in this Code. Provisions of this section shall supersede where any conflict exists. If the director has not approved or denied the completed application within 60 days, the application shall be deemed approved.
2.
Two unit SB 9 projects shall meet the following requirements:
a.
The project application is consistent with Subsection 18.08.080 A.;
b.
The side and rear setbacks of each unit are at least four feet;
c.
The front setback meets the standard of the underlying zoning district or specific plan requirements;

ii.
There is a car share vehicle located within one block of the parcel.
f.
A restrictive covenant shall be recorded upon approval of the project precluding the rental of either unit for a term less than 30 days;
g.
Each dwelling unit shall have access, provide access to, or adjoin the public right-of-way. Accessibility shall be in conformance with the building code and Americans with Disability Act and shall not preclude construction of future public improvements.
3.
If the project is a two unit SB 9 project to be constructed on a site created by an SB 9 urban lot split, no ADU or JADU may be constructed in addition to the project's two units.
4.
Fees for two unit SB 9 projects shall be the same as those assessed for other residential construction projects.
C.
Notwithstanding an SB 9 project's compliance with the above, the director shall deny a complete application if the city's building official makes a written finding, based upon a preponderance of the evidence, that the proposed two unit SB 9 project would have a specific, adverse impact, as defined and determined in paragraph (2) of subdivision (d) of Section 65589.5, upon public health and safety, for which there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact.
