Application Process

1. Confirm whether the work needs a permit by checking the City's permit infogram and exemption list; unless exempt, Imperial requires a permit before erecting, constructing, enlarging, altering, repairing, moving, improving, converting, demolishing, or installing or altering plumbing, gas, drainage, water-heating, or electrical work.
2. Create a Citizenserve account before first use. Registrants must upload a state-issued photo ID or notarized signature; contractors must also upload contractor license information if licensed and a California business license.
3. Submit the building permit application and required plans and documents. For new residential projects, the City requires two complete plan sets and lists minimum submittal items such as plot plan, foundation plan, soils report, floor plan, framing details, elevations, roof and truss plans, MEP information, energy calculations, and engineering calculations if required.
4. Pay the applicable fees. The fee schedule includes a nonrefundable $50 submittal fee, plan-check fees equal to 65% of the building permit fee, and additional state surcharges; fees may be doubled for work started before permit issuance.
5. After permit issuance, schedule required inspections through Citizenserve or by phone or email no later than 5:00 PM on the preceding business day, keep the permit card and approved plans on site, and complete final approval requirements including any construction and demolition recycling closeout when applicable.

General Requirements

Imperial requires a permit before most building, structural, demolition, plumbing, gas, drainage, water-heating, and electrical work unless specifically exempt.

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

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 The reviewed city materials do not publish a separate local permit-expiration handout.

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.

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.

Fees

Minimum permit fee

$50.00 nonrefundable submittal fee for processing a building permit application

Plan check fee

65% of the building permit fee; preliminary plan check fee is $170.00 when charged.

Permit fee formula

Building permit fees are valuation-based under the fee schedule exhibits; plan-check fees are 65% of the building permit fee; additional hourly charges apply for services not otherwise covered.

Reinspection fee

$43.00 construction reinspection fee for more than two requests to inspect the same work item.

Penalty (no permit)

Permit fees are doubled if work starts before permit issuance or approval.

Payment note

Fire Department fees are paid and processed separately from the Community Development Department. New residential guidance states a $300 site plan review deposit is due when the building permit application is submitted. Citizenserve also supports online fee payment.

Fees change. Verify current amounts at the official fee schedule.

Work That Does NOT Require a Permit

• One-story detached accessory structures such as storage sheds, playhouses, and gazebos up to 120 square feet and 8 feet high, subject to setbacks and lot coverage
• Non-masonry fences not over 6 feet high
• Retaining walls not over 4 feet high unless supporting surcharge, certain liquids, or steep retained soil
• Water tanks on grade up to 5,000 gallons with height-to-width ratio not over 2:1
• Sidewalks and driveways not more than 30 inches above adjacent grade and not over a basement or story below
• Painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work that does not alter accessible egress or an accessible route
• Temporary stage sets and scenery
• Above-ground prefabricated pools accessory to Group R-3 occupancy that are less than 24 inches deep and do not exceed 5,000 gallons
• Swings and playground equipment accessory to detached one- and two-family dwellings
• Certain minor electrical, mechanical, and plumbing repair items listed by the City, such as minor repair work, portable appliances, and clearing stoppages or stopping leaks without replacing concealed piping

Important: Exemptions do not authorize work that violates code or other ordinances. Work in the public right-of-way may still require an encroachment permit. If concealed piping must be removed and replaced, the plumbing work becomes new work requiring a permit.
