Committee Memorandum
TO: HOUSING AND HOMELESSNESS DATE: SEPTEMBER 22, 2025
COMMITTEE MEMBERS
FROM: HOUSING AND HUMAN SERVICES WARDS: ALL SUBJECT: PROPOSED AMENDMENTS TO THE MOBILE HOME PARKS RENT STABILIZATION ORDINANCE ISSUE:
Discuss proposed amendment to the Mobile Home Parks Rent Stabilization Ordinance.
RECOMMENDATIONS:
That the Housing and Homelessness Committee:
Receive an update on proposed amendments to the Mobile Homes Parks Rent Stabilization Ordinance; and Provide direction on the proposed amendments to the Mobile Homes Parks Rent Stabilization Ordinance and forward the proposed amendments to the City Council for Consideration.
BACKGROUND:
A significant portion of mobile homeowners or tenants in the City are senior citizens, who live on limited or fixed incomes. City Council wanted 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.
On August 25, 1992, City Council amended Section 5 of the Riverside Municipal Code (RMC) to add Chapter 5.75, establishing a rent stabilization procedure for mobile home park that allowed annual rent increases for the following.
Up to 80% of the change in the Consumer Price Index (CPI) for the year ending in August Changes in property taxes or government mandated costs in excess of 2% per year Capital improvements to existing facilities
Increases in state fees
Rent increases associated with sale of a space
On September 15, 2020, the City Council adopted an amendment to the Riverside Municipal Code Section 5.75.040 to change the Consumer Price Index region data from Los Angeles-Anaheim-Riverside to Riverside-San Bernardino-Ontario and change the CPI year ending from August to July since the U.S. Bureau of Labor Statistics does not produce data in July for the Riverside-San Bernadino-Ontario region.
The following table shows prior annual rental increases based on 80% of the CPI.

From 2011 to 2026, the average rent increase is 2.43%. The lowest rent increase was 0.64% and the highest rent increase was 7.36%.
In 2019, staff was directed to conduct a review of the entire Mobile Home Parks Rent Stabilization Ordinance (Ordinance) that was adopted in 1992. Staff worked with the City Attorney's office to review the current Ordinance and 91 cities and 10 counties mobile home park rent stabilization procedures. Staff identified sections within the Ordinance that could be improved and met with the Western Manufactured Housing Communities Associations (WMA) to discuss the current ordinance and sections that required further clarification. Staff was in the process of scheduling a series of meetings with the WMA, local mobile home park owners, and park residents to review the Ordinance, but these meetings were placed on hold due to the Coronavirus pandemic.
During the 2022 Ordinance annual public hearing, when the maximum rent increase for 2023 was announced at 7.36%, the highest rent increase experienced under the Ordinance, City Council directed staff to research capping rent increases and to work with mobile home park owners and residents through community outreach and present recommended amendments to the Ordinance to the Housing and Homelessness Committee for discussion.
Staff rereviewed the proposed amendments to the Ordinance with the City Attorney’s Office. The proposed amendments to the Ordinance were then shared with the park residents in June 2024 and with the WMA and local mobile home park owners in July 2024 to solicit feedback.
On September 23, 2024, the Housing and Homelessness Committee were presented with the amendments in Table 1, which resulted in the Committee conceptually approving all the action items except for two action items – 7 and 9 for City Council’s consideration.
On February 4, 2025, the proposed amendments were then introduced to City Council for discussion. Following discussion, City Council further amended some of the proposed changes, which were later approved during the March 4, 2025 meeting and are shown in Table 1.
