The City Council first entered the mobilehome space rent control arena on May 23, 1979 through the adoption of Ordinance No. 79-470-U, a mobilehome space rent increase moratorium. This action was taken due to the request of a number of mobilehome park residents in the city who were either experiencing or about to experience some rather steep rent increases at the time. Subsequently, an ordinance creating a Mobilehome Rent Review Board (Board or MRRB), composed of equal numbers of Park Residents, Park Owners and At-Large Members was adopted on August 20, 1979 through Ordinance No. 79-485-U (Ordinance). The Ordinance created a 15-member Board empowered to grant rent increases based on 11 factors described in the Ordinance. In addition, the Ordinance extended the rent increase moratorium until the MRRB became operational.

In the 1990s, the Board was reduced further through Ordinance No. 92-983, No. 92-988-U, and No. 92-994-U to five (5) members: two (2) Park Resident Members, two (2) Park Owner Members and one (1) mediator. There were again three (3) Alternates; however, they were once again one (1) from each of the above groups.

In 1998, the Board was again modified back to the seven-member format through Ordinance No. 98-1130 with two (2) Resident Homeowners, two (2) Park Owners, and three (3) At-Large Members from the community who are not Resident Homeowners, Park Owners, landlords, property managers, or tenants in multifamily housing. There are now eight (8) Alternate Members: two (2) Alternate Resident Homeowners, two (2) Alternate Park Owners, and four (4) Alternate At-Large Members.
