Required documents
- Building permit application
- Project valuation and description
- Contractor or owner-builder declarations
- Workers' compensation declaration
- Plans and specifications
- For new residential submittals: two complete plan sets plus plot plan, foundation plan, soils report, floor plan, framing sections, details, elevations, roof or truss plans, electrical, plumbing, and mechanical layouts, energy calculations, and engineering calculations if required
- Building code
- Imperial updated Chapter 6 on November 19, 2025 to adopt the 2025 California Building Code set, including the 2025 California Administrative, Building, Residential, Electrical, Mechanical, Plumbing, Energy, Fire, Historical, Green Building Standards, Referenced Standards, and related listed codes.
- Permit validity
- The fee schedule says plan-check fees remain valid if the permit is obtained within six months of the plan-check application. The reviewed city materials do not publish a separate local permit-expiration handout.
- Owner-builder
- The owner-builder declaration states the owner may do the work personally or through employees receiving wages as sole compensation, and the structure cannot be intended or offered for sale; sale or offer for sale within one year after completion creates a rebuttable presumption the work was undertaken for sale.
- Contractor requirements
- The permit form requires the contractor to affirm licensure under California Business and Professions Code section 7000 et seq. The Citizenserve registration page requires licensed contractors to upload contractor license documentation, and all contractors must upload a California business license issued by a county in the state.
