Does a resident need a permit from HCD to remodel their home, even though all the changes and upgrades are on the inside?

Homeowners need a permit from the state Department of Housing and Community Development (HCD). Only HCD, not local government, may issue permits for alterations of a mobile home’s structural, fire safety, electrical, plumbing or mechanical components. The two offices that handle such permits are:

Northern California Area
Field Operations
9342 Tech Center Drive, #550

916-255-2501

Southern California Area
Field Operations
3737 Main Street, #400
Riverside, CA 92501

Recap:
● Permits are required. No exceptions.
