This chapter shall be referred to as the "Accessory Dwelling Unit Ordinance." (Ord. 1800 §4, 2020).
19.72.020 Purpose and findings.
The purpose of this chapter is to provide regulations for accessory dwelling units, also known as second family dwelling units, in-law units, and guest houses.
A. The California State Legislature adopted Government Code Section 65852.2, which establishes permitting rules for accessory dwelling units. The state law requires ministerial review of permit applications for compliant accessory dwelling units. The law prohibits cities and counties from creating permitting requirements that are inconsistent with Government Code Section 65852.2, and provides that any local law in conflict with these rules is now void.
B. This chapter is intended to address the state law by creating a process for permitting accessory dwelling units that is consistent with Government Code Section 65852.2.
C. The stated intent of Government Code Section 65852.2 includes (1) using existing housing resources to address California’s housing crisis, (2) reducing barriers to affordable housing, and (3) providing additional income to homeowners. (Ord. 1800 §4, 2020).
19.72.030 Definitions.
"Accessory dwelling unit" means an attached or a detached residential dwelling unit which provides complete independent living facilities for one or more persons. It shall include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as the single-family dwelling is situated. An accessory dwelling unit also includes an efficiency unit, as defined in Section 17958.1 of the California Health and Safety Code, and it includes a manufactured home, as defined in Section 18007 of the California Health and Safety Code.
"Public transit" means a location, including, but not limited to, a bus stop or train station, where the public may access buses, trains, subways, and other forms of transportation that charge set fares, run on fixed routes, and are available to the public. (Ord. 1800 §4, 2020).
19.72.040 Permitting.
A. Subject to compliance with Section 19.72.050, accessory dwelling units are allowed in all zoning districts that allow residential dwellings. Accessory dwelling units are deemed not to exceed the allowable density for the parcel, and deemed consistent with the general plan. The applicant shall be the owner of the property or the owner’s designee.
B. An application for an accessory dwelling unit that meets the development standards of this chapter shall be processed ministerially within sixty days of the application being deemed complete. If the application is submitted with an application to create a new single-family dwelling, then the applications may be considered together under the single-family dwelling application timeline.
C. If the applicant seeks a waiver or modification of the development standards for a ministerial permit, then the applicant may apply for a use permit under Chapter 19.56. (Ord. 1800 §4, 2020).
19.72.050 Accessory dwelling unit regulations.
Applicants for an accessory dwelling unit must comply with all applicable local and state laws. If a conflict exists between the laws in this chapter and other laws within the county’s municipal code, the laws in this chapter shall control. All proposed accessory dwelling units must comply with all the below-listed general regulations and must also comply with either the Category 1 or Category 2 regulations.
A. General Regulations. These general regulations apply to all accessory dwelling unit permit applications.
1. Located on Same Parcel as Residential Dwelling. The proposed accessory dwelling unit shall either be (a) attached or located within the living area of the proposed or existing primary dwelling or (b) detached from the proposed or existing primary dwelling and located on the same parcel as the proposed or existing primary dwelling.
2. Building, Fire, and Life Safety. Unless provided otherwise within this chapter, all applicable building and fire code requirements shall apply except that the building code shall not restrict an applicant’s ability to obtain a permit for an accessory dwelling unit that is up to sixteen feet in height where all other code requirements are satisfied. A mobile home, recreational vehicle, park model recreational vehicles, yurts, tents, cargo containers, or other movable or temporary habitable spaces that do not comply with the California Building Standards Code shall not be used as an accessory dwelling unit.
3. Water and Waste Water. The applicant shall comply with Section 14.06.055 (Production requirements for water supply wells). Where a private sewage disposal system is being used, the system shall require approval by the environmental health department. Approval of the accessory dwelling unit is subject to the environmental health department’s certification that sufficient water and waste water services exist for the unit.
4. Certificate of Occupancy. A certificate of occupancy may not be issued for the accessory dwelling unit until a certificate of occupancy is issued for the primary dwelling.
5. Fire Sprinklers. Applicants shall comply with the California Building Code with respect to installation of fire sprinklers except that fire sprinklers are not required in accessory dwelling units if they are not required for the primary residence.
6. Setback. A four-foot setback is required from the side and rear lot lines for new structures in areas where state responsibility area fire and life safety regulations (Chapter 15.30) do not apply.
B. Category 1 Permits. Accessory dwelling units permitted under this subsection shall be rented for a term longer than thirty days. Applicants seeking a Category 1 accessory dwelling unit permit must also comply with the following:
1. Number of Accessory Dwelling Units Allowed. Only one accessory dwelling unit is permitted on a parcel on which a residential dwelling exists or is proposed to exist.
2. Total Floor Area. The minimum floor area shall be the minimum required for an efficiency dwelling unit as defined in Health and Safety Code Section 17958.1. The maximum floor area shall be the floor area of the primary dwelling on the parcel; however, if the primary dwelling is less than one thousand square feet, then the maximum floor area shall be eight hundred fifty square feet for an accessory dwelling unit that has less than two bedrooms, and one thousand square feet for an accessory dwelling unit that has two or more bedrooms.
3. Parking.
a. One additional off-street parking space is required for the accessory dwelling unit. The space may be provided as tandem parking on a driveway. Off-street parking is permitted in setback areas unless the county specifically finds setback parking is not feasible based on site or regional topographical or fire and life safety conditions.
b. When a parking structure is converted to an accessory dwelling unit, additional parking, or replacement of existing parking, is not required.
c. The parking requirement in subsection (B)(3)(a) of this section does not apply if the accessory dwelling unit is located within one-half mile walking distance of public transit, or is located within an architecturally and historically significant historic district, or is part of the proposed or existing primary residence or an existing accessory structure, or is located within one block of a car share vehicle.
C. Category 2 Permits. Accessory dwelling units permitted under this subsection shall be rented for a term longer than thirty days. Applicants are not required to provide off-street parking for Category 2 permits. Applicants seeking a Category 2 permit must meet the requirements for one of the following four application types.

The limit of accessory dwelling units allowed under this subsection shall be the total of up to twenty-five percent of the existing multifamily dwelling units on the parcel. One accessory dwelling unit is allowed if there are seven or fewer existing multifamily dwelling units on the parcel.

19.72.060 Renting and selling--Subdivision--Deed restriction.
The unit may be rented separate from the primary residence, but may not be sold or otherwise conveyed separate from the primary residence. If an owner seeks to divide the parcel, the owner must meet all subdivision requirements as though the accessory dwelling unit did not exist and shall increase the size of the accessory dwelling unit if necessary to meet the minimum square footage and dimensions for a dwelling unit as set forth in Section 19.26.010. Prior to the issuance of a certificate of occupancy for an accessory dwelling unit, the county may require the applicant to file a deed restriction consistent with this provision.
