When a permit is required
Permit triggers and exempt work for Signal Hill
Signal Hill states no building or structure may be constructed, enlarged, altered, repaired, moved, improved, removed, converted, demolished, or changed in occupancy, and no regulated electrical, gas, mechanical, or plumbing work may occur, without first obtaining a permit. The City handout gives examples including altered window/door framing, decks/stairs/platforms over 30 inches, remodels affecting framing or MEP systems, roofing/stucco/siding over 100 square feet when framing/plywood/water-resistive barrier is disturbed, change of use or occupancy, grading/excavating/repaving, any fence or retaining wall, MEP installation or replacement, kitchen or bath remodels affecting cabinets/countertops with MEP work, and certain sheds.
- Exempt Movable cases, counters, and partitions not over 5 feet 9 inches high and not blocking accessibility or exits.
- Exempt Painting, papering, and floor coverings.
- Exempt Non-structural concrete flatwork such as walkways and driveways.
- Exempt Portable structures or equipment installed for less than 180 days.
- Exempt Sheds or playhouses less than 120 square feet and not higher than 7 feet, subject to Planning Department approval.
- Exempt Decks, platforms, walkways, and driveways not higher than 30 inches above grade and within front or side setbacks, subject to Planning Department approval.
Note: Signal Hill states permit exemptions do not authorize work that violates the code or other laws. The City also expressly states that any fence or retaining wall requires a permit, and its Codes page says installation and construction of fences and walls are not exempt from permit requirements.
- Online permit application plus project plans and, as applicable, structural calculations, energy calculations, soils report, seismic report if required, grading plan, and erosion control plan. The portal also tells applicants to upload all required documents and to review linked application instructions before submittal.
- Building code
- The City Codes page lists the 2025 California Administrative Code, 2025 California Building Code, 2025 California Electrical Code, 2025 California Mechanical Code, 2025 California Plumbing Code, 2025 California Residential Code, 2025 California Green Building Standards Code, and the 2023 County of Los Angeles Fire Code, with local notes including that fences and walls are not exempt from permit requirements.
- Permit validity
- The City application form states permits become null and void if work does not start within 180 days of issuance or if work is suspended or abandoned for 180 days. The Project Development Guide also imposes overall construction time limits by project size, such as 180 or 360 days for many residential additions/repairs/accessory structures, 540 days for 1 to 2 new dwelling units, and 540 to 720 days for non-residential work depending on size.
- Owner-builder
- The City permit application includes an owner-builder declaration. An owner may claim exemption from contractor licensing if the owner performs the work with employees and the improvement is not intended or offered for sale, or if the owner contracts exclusively with licensed contractors. The form notes that if the improvement is sold within one year of completion, the owner-builder has the burden of proving it was not built for sale.
- Contractor requirements
- The permit application requires either a licensed contractor declaration or an owner-builder declaration. The portal and Project Development Guide also state all contractors working in Signal Hill must have a City of Signal Hill business license before permit issuance. The Codes page adds that electrical work on commercial, industrial, or multi-family structures with more than two units must be performed by a state-licensed electrical contractor.
