Residential Alteration–Building

A Building Permit is required for an owner or contractor of a property to alter an existing building or structure. Prior to starting construction you may be required to submit plans and any necessary supporting documentation for review and approval by the County. The plan review process involves verifying compliance with the California Building Codes, San Bernardino County Fire Code, San Bernardino County Development Code, and/or any required laws and regulations.
