How does the county assessor determine the value of my manufactured home?
Manufactured homes are subject to Proposition 13 under which the county assessor determines the base year value of a manufactured home, which is generally the market value at the time of purchase. After the first assessment annual increases to the base year value are limited to the inflation rate, as measured by the California Consumer Price Index, or 2 percent, whichever is less. Any new construction will have its own separate base year value. When the manufactured home is sold, it will be reassessed at its current fair market value and a new base year value will be established. If your manufactured home is located on land that you own, the land will be assessed separately. If you live in a tenant-owned mobilehome park, a different rule may apply.
The basic structure is assessable as well as all accessories, including, but not limited to: awnings, fences, windbreakers, storage cabinets, heaters, carport, water coolers, cabanas, porches, and skirting.
Section 5803(b) of the Revenue and Taxation Code specifically provides that the assessed value of a manufactured home on leased or rental land is not to include any value attributable to the land where the home is located. This means that the county assessor must not increase the value of your mobile home because of positive location nor decrease the value because of negative location.
