City of Gardena

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.

• Exempt Construction of decks and platforms less than 30 inches high, not attached to a dwelling, plus open walkways and driveways
• Exempt Installation of ceramic tile on floors and countertops and on walls not more than 69 inches high and not in showers or tubs
• Exempt Prefabricated swimming pools not exceeding 24 inches depth or 5,000 gallon capacity, without electrical or plumbing fixtures
• Exempt Construction of cases, counters, and partitions less than 5 feet 9 inches high
• Exempt Painting, papering, and similar finish work
• Exempt One-story detached accessory buildings used as tool and storage sheds, playhouses, and similar uses, if roof area does not exceed 120 square feet

Note: Gardena describes these as the "most common exceptions," not a complete exemption list. Zoning, energy, fire, right-of-way, utility, or trade-permit rules may still apply depending on the project.

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.

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.

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.
