Code Section

18300.  

(a) This part applies to all parts of the state and supersedes any ordinance enacted by any city, county, or city and county, whether general law or chartered, applicable to this part. Except as provided in Section 18930, the department may adopt regulations to interpret and make specific this part and, when adopted, the regulations shall apply to all parts of the state.

(b) Upon 30 days’ written notice from the governing body to the department, any city, county, or city and county may assume the responsibility for the enforcement of both this part and Part 2.3 (commencing with Section 18860) and the regulations adopted pursuant to this part and Part 2.3 (commencing with Section 18860) following approval by the department for the assumption.

(c) The department shall adopt regulations that set forth the conditions for assumption and may include required qualifications of local enforcement agencies. The conditions set forth and the qualifications required in the regulations shall relate solely to the ability of local agencies to enforce properly this part and the regulations adopted pursuant to this part. The regulations shall not set forth requirements for local agencies different than those that the state maintains for its own enforcement program. When assumption is approved, the department shall transfer the responsibility for enforcement to the city, county, or city and county, together with all records of parks within the jurisdiction of the city, county, or city and county.

(d) (1) In the event of nonenforcement of this part or the regulations adopted pursuant to this part by a city, county, or city and county, the department shall enforce both this part and Part 2.3 (commencing with Section 18860) and the regulations adopted pursuant to this part and Part 2.3 (commencing with Section 18860) in the city, county, or city and county, after the department has given written notice to the governing body of the city, county, or city and county, setting forth in what respects the city, county, or city and county has failed to discharge its responsibility, and the city, county, or city and county has failed to initiate corrective measures to carry out its responsibility within 30 days of the notice.

(2) Where the department determines that the local enforcement agency is not properly enforcing this part or Part 2.3 (commencing with Section 18860), the local enforcement agency may appeal the decision to the director of the department.

(e) (1) Any city, city and county, or county may cancel its assumption of responsibility for the enforcement of both this part and Part 2.3 (commencing with Section 18860) by providing written notice of the cancellation to the department. The department shall assume responsibility within 90 days after receipt of the notice.

(2) Any local enforcement agency that relinquishes enforcement authority to the department shall remit to the department any fees collected pursuant to Section 18502 that have not been expended for purposes of this part, except that, for fees collected pursuant to subdivision (c) of that section, the local enforcement agency shall pay to the department a sum that is equal to the percentage of the year remaining before outstanding permits to operate expire. In addition, the local enforcement agency that relinquishes enforcement authority to the department shall remit to the department any fees collected pursuant to this part for permits to construct or for plan review, or both, for which a final approval of the construction has not yet been issued.

(f) Every city, county, or city and county, within its jurisdiction, shall enforce this part and the regulations adopted pursuant to this part, as they relate to manufactured homes, mobilehomes, or recreational vehicles, and to accessory buildings or structures located in both of the following areas:

(1) Inside of parks while the city, county, or city and county has assumed responsibility for enforcement of both this part and Part 2.3 (commencing with Section 18860).

(2) Outside of parks.

(g) This part shall not prevent local authorities of any city, county, or city and county, within the reasonable exercise of their police powers, from doing any of the following:

(1) From establishing, subject to the requirements of Sections 65852.3 and 65852.7 of the Government Code, certain zones for manufactured homes, mobilehomes, and mobilehome parks within the city, county, or city and county, or establishing types of uses and locations, including family mobilehome parks, senior mobilehome parks, mobilehome condominiums, mobilehome subdivisions, or mobilehome planned unit developments within the city, county, or city and county, as defined in the zoning ordinance, or from adopting rules and regulations by ordinance or resolution prescribing park perimeter walls or enclosures on public street frontage, signs, access, and vehicle parking or from prescribing the prohibition of certain uses for mobilehome parks.

(2) From regulating the construction and use of equipment and facilities located outside of a manufactured home or mobilehome used to supply gas, water, or electricity thereto, except facilities owned, operated, and maintained by a public utility, or to dispose of sewage or other waste therefrom when the facilities are located outside a park for which a permit is required by this part or the regulations adopted pursuant thereto.

(3) From requiring a permit to use a manufactured home or mobilehome outside a park for which a permit is required by this part or by regulations adopted pursuant thereto, and require a fee therefor by local ordinance commensurate with the cost of enforcing this part and local ordinance with reference to the use of manufactured homes and mobilehomes, which permit may be refused or revoked if the use violates this part or Part 2 (commencing with Section 18000), any regulations adopted pursuant thereto, or any local ordinance applicable to that use.

(4) From requiring a local building permit to construct an accessory structure for a manufactured home or mobilehome when the manufactured home or mobilehome is located outside a mobilehome park, under circumstances when this part or Part 2 (commencing with Section 18000) and the regulations adopted pursuant thereto do not require the issuance of a permit therefor by the department.

(5) From prescribing and enforcing setback and separation requirements governing the installation of a manufactured home, mobilehome, or mobilehome accessory structure or building installed outside of a mobilehome park.

(h) (1) A city, including a charter city, county, or city and county, shall not require the average density in a new park to be less than that permitted by the applicable zoning ordinance, plus any density bonus, as defined in Section 65915 of the Government Code, for other affordable housing forms.

(2) A city, including a charter city, county, or city and county, shall not require a new park to include a clubhouse. Recreational facilities, recreational areas, accessory structures, or improvements may be required only to the extent that the facilities or improvements are required in other types of residential developments containing a like number of residential dwelling units.

(3) A city, including a charter city, county, or city and county, shall not require the setback and separation requirements authorized by paragraph (5) of subdivision (g) to be greater than those permitted by applicable ordinances for other housing forms.
