Summary

When a San Luis Obispo County mobilehome park owner seeks a rent increase beyond the standard cost-of-living cap, County Code § 25.07.010(c) requires personal or mailed notice to every affected tenant of the proposed increase and of the hardship exception application filed with the Mobilehome Rent Review Board.

These county ordinances apply to unincorporated areas of San Luis Obispo County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The owner shall serve each affected tenant, either personally, or by mail, with notice of the rent increase or decrease or change in services or facilities requested and with notice that application or approval of same is being filed with the board. Proof of service complying with the title and all applicable state laws shall be filed with the board concurrent with the filing of the application. Copies of the application shall be available free of charge to any affected tenants requesting same at the business office in the affected park.

Violations & Fines

An owner who pushes a hardship-exception increase through without serving the required notice, or without filing proof of service with the board, has not satisfied § 25.07.010 and the application can be rejected on procedural grounds. Because the ordinance folds notice into the hardship-hearing process rather than a separate penalty schedule, the practical remedy is a tenant challenge before the Mobilehome Rent Review Board, followed by appeal to the Board of Supervisors within 15 days of its decision (§§ 25.10.010, 25.11.010).

Frequently Asked Questions

Does every mobilehome rent increase in the county require written notice?
Only increases that exceed the standard 60-percent-of-CPI formula. Those go through a hardship exception application under § 25.07.010, and that application is what triggers the personal-or-mail notice requirement to every affected tenant.
How must the park owner deliver the rent increase notice?
Either personally or by mail to each affected tenant, under § 25.07.010(c). The notice has to describe the requested increase, decrease, or service change and state that a hardship application is being filed with the Mobilehome Rent Review Board.
Can I see the park owner's rent increase application?
Yes. Section 25.07.010(c) entitles any affected tenant to a free copy of the application from the park's business office once it has been filed with the Mobilehome Rent Review Board.
How soon after the application is filed will a hearing happen?
The board must set the hearing no less than 10 days and no more than 30 days after it receives the application and proof of service, and both the owner and tenants get written notice of the date, time, and place (§ 25.07.010(d)).
