Understanding mobile home rent stabilization
Chapter 5.75 of the Riverside Municipal Code (“RMC”) governs all mobile home parks within the City of Riverside.
Riverside Municipal Code · Chapter 5.75
Program & applicability
RMC Section 5.75.010. Findings and Purpose
The chapter shall be known as the Mobile Home Parks Rent Stabilization Program. The relative immobility of mobile homes, the substantial investment involved in the purchase of a mobile home, and the expense, difficulty, and risk of damage in moving a mobile home has created a captive market of mobile home owners and tenants in the City. A significant portion of mobile home owners or tenants in the city are senior citizens, many of whom live on limited or fixed incomes. It is therefore the purpose of the City Council to provide a mechanism to prevent excessive, unreasonable and frequent rent increases while at the same time recognizing the need of mobile home park owners to receive a just and reasonable return on their investment.
(Ord. 7702, § 1(Exh. A), 2025)
RMC Section 5.75.025. Applicability
The provisions of this chapter shall apply to any mobile home park within the corporate limits of the City and to those residents who reside in or hold an ownership in a Mobile Home under a Rental Agreement, whether oral or in writing, of 12 months or less in duration. The provisions of this chapter shall not apply to any Mobile Home Park or portion thereof excluded pursuant to the provisions of Section 798.45 of the Civil Code or to any Rental Agreement exempt pursuant to the provisions of Section 798.21 of the Civil Code, as amended from time to time. (Ord. 7757, § 129, 2026; Ord. 7702, § 1(Exh. A), 2025)
