Full Breakdown
Riverside County's Mobilehome Park Rent Stabilization Ordinance (RCC Chapter 5.36) covers mobile home space rent in the unincorporated county only, not Riverside, Moreno Valley, Corona, Temecula or the county's 28 cities, which set their own rules. Under RCC § 5.36.100, any rent adjustment notice a park owner sends must carry the certification the ordinance requires; the county's mobilehome rent arbitrator or board can deny the whole rent adjustment if the owner failed to comply with this or any other chapter requirement. The rule applies only to mobile home space rent, not conventional house or apartment leases.
Violations & Fines
Failing to certify compliance in a rent adjustment notice gives the arbitrator or mobilehome board grounds to deny the entire proposed rent increase for that space.
