Rocklin, CA Rental Property Rules: Rent Control (2026)

Rocklin adopted this ordinance in 1988 under Ord. 594 after finding, in Section 2.46.010, that mobile home park residents are mostly older fixed-income owners with limited ability to relocate a mobile home, and that lot rents had climbed sharply in the two years before rent control took effect. The chapter exists, per Section 2.46.020, to prevent excessive or exploitive rent increases while still letting a park owner earn a fair and reasonable return, and it runs until a lot has a voluntary vacancy.

Coverage is narrower than it first looks. Section 2.46.320 exempts any park or lot in a park with fewer than ten spaces outright. Section 2.46.355 exempts a park whose plumbing, electrical or sewer permit was first issued on or after August 31, 1988. Section 2.46.340 exempts a lot under a voluntary lease of more than twelve months if the lease itself discloses the exemption.

For covered lots, Section 2.46.400 lets a landlord raise rent every twelve months, without any city review, by a sliding share of the California Consumer Price Index for All Urban Consumers: the full CPI change up to five percent, 75 percent of the change or five percent (whichever is greater) between five and ten percent, and 66 percent of the change or 7.5 percent (whichever is greater) above ten percent. Anything above that figure requires a petition filed with the city manager 60 to 120 days ahead of the increase under Section 2.46.440, then a contested hearing before an administrative hearing officer chosen through the mobile home rent review commission, who can also add a flat 3 percent adjustment under Section 2.46.480 or, on a fair-market-rent petition under Section 2.46.490, order a formal appraisal; a fair-market-rent decision then locks in for four years.
