California Code, Health and Safety Code - HSC § 18872.1

(a) Park lot lines shall not be created, moved, shifted, or altered without a permit issued to the park owner or operator by the enforcement agency and the written authorization of the occupant or occupants, resident, or tenant, if any, of the lot or lots on which the lot line will be created, moved, shifted, or altered.

(b) No park lot line shall be created, moved, shifted, or altered, if the action will place an occupant of a lot in violation of any separation or space requirements under this part or under any administrative regulation.

(c) The park owner or operator shall submit a written application for the lot line alteration permit to the enforcement agency. The application shall include a list of the names and addresses of the occupants, residents, or tenants, if any, of the lot or lots that would be altered by the proposed lot line change and the written authorization of the occupants, residents, or tenants. The enforcement agency may require, as part of the application for the permit, that the park owner or operator submit to the enforcement agency documents needed to demonstrate compliance with this section, including, but not limited to, a detailed plot plan showing the dimensions of each lot altered by the creation, movement, shifting, or alteration of lot lines. If submission of a plot plan is required, the park owner or operator shall provide a copy of the plot plan to the occupants, residents, or tenants of each lot that would be altered by the proposed lot line change and provide the enforcement agency, as part of the application, with proof of delivery by first-class postage prepaid of the copy of the plot plan to the affected occupants, residents, or tenants.

(d) The department may adopt a fee, by regulation, payable by the applicant, for the permit authorized by this section.

(e) If the department is the enforcement agency and the application proposes to reduce or increase the total number of lots available for occupation, the applicant shall submit a copy of that application and any information required by subdivision (c) to the local planning agency of the jurisdiction where the park is located.
