Get 433c Form

Permit is required if sheets are installed; especially on the ceiling where the drywall can fall down.

In California, mobile homes are classified as manufactured homes, which must be registered with the Department of Housing and Community Development.

Unlike the 433C, the 433A is more than just a paper document. The process requires pulling a permit with the jurisdictional building department, installing a proprietary or approved engineered system, subsequent inspection by the building authority and then recording that document.

ing to the California Building Standards Code, no building or structure may be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished unless a separate permit for each building or structure has first been obtained from the building official.

To perform any work on your mobilehome, manufactured home, commercial modular, special purpose commercial modular or multifamily manufactured home, you must submit an application for permit (form HCD MH 415) (PDF).

Contractors who violate the law are subject to disciplinary action by CSLB, including civil penalty assessments of up to $5,000 per violation, an order of correction that requires payment of permit fees and any assessed penalties imposed by the local building department, and suspension or revocation of the license.
