Summary

Rancho Cucamonga gives mobile home park tenants a formal way to challenge steep rent hikes. Under Municipal Code Chapter 8.10, tenants have 30 days after an owner gives notice of a rent increase exceeding the local Consumer Price Index to petition the city clerk for a mandatory meet-and-confer session with the park owner.

Within 30 days after an owner of a mobilehome park has given notice to the tenants thereof of a proposed rent increase which exceeds the consumer price index as outlined in section 8.10.050, the tenants may petition the city to call a mandatory meet-and-confer session between the mobilehome park owner and a committee representing the tenants for the purpose of discussing the proposed rent increase and the reasons therefor.

Full Breakdown

Violations & Fines

There is no fine schedule in this chapter; instead, non-compliance affects the increase itself. Under Section 8.10.110, if the tenants' committee skips a scheduled meet-and-confer or mediation session, the city clerk dismisses the petition outright. If the park owner or a representative fails to attend, the proposed rent increase cannot take effect until the owner attends a rescheduled session, effectively freezing the increase.

Frequently Asked Questions

How long do mobile home tenants have to petition a rent increase in Rancho Cucamonga?
Thirty days from the date the mobilehome park owner gives notice of the proposed increase, per Section 8.10.020. The petition goes to the city clerk and must be signed by tenants representing more than half of the occupied spaces to trigger a mandatory meet-and-confer session.
Does this chapter cap mobile home rent increases?
No. Chapter 8.10 does not set a rent ceiling; it only forces a meet-and-confer and, if needed, mediation when an increase exceeds 75 percent of the area CPI change over the prior year, per Section 8.10.050(C).
What happens if the park owner ignores the mediation session?
Under Section 8.10.110(B), the proposed rent increase cannot become effective until the owner or an authorized representative actually attends a rescheduled meet-and-confer or mediation session before the West End Mediation Board.
