San Luis Obispo County, CA Rental Property Rules: Rent Control (2026)

Base rent is fixed at each space's monthly rent as of December 31, 1982, per § 25.06.010(a)(1); any cut in services or amenities after that date requires a matching rent decrease. Once a year, an owner can raise rent by up to 60 percent of the change in the CPI for All Urban Consumers, Los Angeles-Long Beach-Anaheim area, measured over the prior twelve months and calculated from the date the last increase took effect (§ 25.06.010(b)-(c)). Rent increases tied to a change of mobilehome ownership are capped separately at 10 percent of the prior space rent (§ 25.06.011); rent is unrestricted on spaces that go vacant because the mobilehome itself is relocated out of the park.

The ordinance exempts spaces rented for nonresidential use, stays of 20 days or less, government-run parks, tenancies under a lease longer than month-to-month (for the lease term), and parks that sell or condominiumize their lots (§ 25.03.010). A three-member Mobilehome Rent Review Board, made up of the county assessor, auditor, and clerk-recorder (with the treasurer-tax collector and sheriff-coroner as alternates), hears any owner request to exceed the formula increase, known as a hardship exception, for a $300 filing fee (§§ 25.04.010, 25.07.010(b)). The board rules on the preponderance of the evidence within 20 days of the hearing, and either side can appeal to the Board of Supervisors within 15 days of the decision (§§ 25.09.010, 25.10.010, 25.11.010).
