General Requirements

Gardena states most residential, commercial, and industrial construction and demolition work, including new construction, additions, remodels, repairs, and alterations, requires a permit. The City specifically lists signs, banners, fences, reroofs, electrical upgrades, plumbing upgrades, and window change-outs as permit-triggering work.

Required Documents

• Completed permit application
• plans in PDF
• relevant project information
• and, depending on scope, professionally prepared plans, structural calculations, soils report, lot survey map signed by a licensed surveyor or civil engineer, Title 24 energy calculations, shoring details, accessibility information, and other technical reports. The application form requests owner, contractor, designer, valuation, square footage, and work description details.

Permit validity

Gardena's published materials conflict. The Permit Information page says a permit is valid for 180 days unless work is active and progressing. The FAQ page says permits become void if substantial progress has not been made after 6 months. The Building Services page says permits are valid for 1 year and void after 1 year without substantial progress verified by inspection. This should be confirmed with Building & Safety before relying on a deadline.

Building code

The City's current Community Development page announces that new 2025 building codes became effective January 1, 2026. Gardena also has a posted code update notice showing adoption of the 2022 California Building Standards Code effective January 1, 2023, so the currently operative cycle appears to have advanced to the 2025 code set as of January 1, 2026.

Owner-builder

Owner-builders may pull permits if they sign the required declaration. Gardena states owner-builders doing the work themselves cannot intend the structure for sale, must live in it for 1 year after completion if they later sell, and may improve only 2 properties in any 3-year period; alternatively, the owner-builder may hire only licensed contractors with current City business licenses.

Contractor requirements

Permits may be pulled only by properly licensed individuals under California Business and Professions Code section 7031.5 or persons exempt under section 7044. Gardena also requires a valid City business license for licensed contractors. Prior to permit issuance, workers' compensation documentation is required unless an exemption applies.

Fees

Minimum permit fee

For Building/Demolition permits, the schedule shows $34.00 for residential valuation up to $500 and $34.00 for commercial valuation up to $500. Trade permits also carry separate issuance and itemized fees.

Plan check fee

Building plan check fee is 100% of the building permit fee. Title 24 / energy-related building plan check fee is also listed at 100% of the building permit fee. Over-the-counter plan check fees are listed separately by level.

Permit fee formula

Building and demolition permit fees are valuation-based. Mechanical, electrical, and plumbing permits are generally itemized by fixture, equipment, service size, or permit type. The City also states permit and plan review fees are based on project valuation including construction, finish work, painting, roofing, plumbing, and permanent equipment.
