Santa Rosa, CA Rental Property Rules: Rent Increase Notice (2026)

040(H) of the mobilehome rent control chapter sets the notice owners must give for every rent increase or new/increased capital improvement or capital replacement pass-through charge: it must be filed with the Clerk of the Santa Rosa Mobilehome Rent Control Program and delivered to each affected mobilehome owner at least 90 days before the increase takes effect, or as required by the state Mobilehome Residency Law if that period is longer. The notice must identify the park, state the dollar amount and percentage of the increase, itemize every new or increased pass-through and additional rent charge, name the specific space affected, give the effective date, explain how the increase was calculated, and disclose the date rent on that space was last increased.

The notice must also tell the mobilehome owner about the right to petition for review and that a petition form is available from the Clerk. 120: an affected owner, or a group representing 50 percent of a park's spaces (or 50 spaces, whichever is fewer), has 30 days from that notice to file a petition challenging a government-mandated expense or capital replacement pass-through before the Arbitrator.
