In 1992 the City Council adopted a Mobilehome Park Rent Control Ordinance to "assure that economic hardship to a substantial number of mobilehome park tenants in the City, many of whom are senior citizens on low fixed incomes, does not occur".  The ordinance also established "a mechanism to assist in in the resolution of disputes that may arise from time to time between tenants and management of mobilehome parks regarding the rates charged for the rental or lease of space". The 1992 ordinance also established the Mobilehome Park Rental Review Board which served as the hearing body for proposed rental increase applications.

On April 18, 2016 after many years of talks, negotiations, hearings and meetings with the mobilehome park homeowners associations and their legal counsel and park owners, and their legal counsel, the City Council adopted Ordinance No. 02-2016, amending Chapter 9.80 of the City of Sonoma Municipal Code regarding the protection of rents for spaces in mobilehome parks.

The new ordinance updates some of the 1992 regulations, adds additional clarification and eliminated the Mobilehome Park Rent Review Board.  Applications for rent increases are now submitted to the City Manager.  Appeals of City Manager decisions are heard by a hearing officer selected through the California Office of Administrative Hearings (OAH).

Chapter 9.80 can be viewed in the Municipal Code.  For questions, contact the City Manager's Office.
