When a permit is required
Permit triggers and exempt work for San Gabriel
The city states permits are required when someone constructs, alters, demolishes, or repairs a structure, electrical, plumbing, or mechanical system. Examples the city expressly says require permits include window replacement, gas lines, sprinklers, sinks/showers/toilets, central air-conditioning, water heaters, new outlets, new plumbing, pools/spas, patio enclosures, additions, patio covers, reroofing, solar, business signs, dumpsters in front of property, and walls or fences.
- Exempt One-story detached accessory structures such as tool/storage sheds, playhouses, and similar structures up to 120 square feet, with no mechanical, electrical, or plumbing, still subject to zoning setback/height and fire-code compliance
- Exempt Landscape planters up to 24 inches above lowest adjacent grade, subject to zoning height limits
- Exempt Decks, platforms, walkways, sidewalks, and driveways not more than 30 inches above adjacent grade, not over a basement/story below, and not part of an accessible route; one city handout version also notes decks/platforms not exceeding 200 square feet and not attached to a dwelling
- Exempt Painting, papering, tiling, carpeting, and similar finish work that does not involve electrical, mechanical, or plumbing work and is not part of a code-enforcement case
- Exempt Prefabricated above-ground swimming pools accessory to a single-family dwelling under the stated depth/capacity thresholds in the city handout
- Exempt Swings and other playground equipment accessory to detached one- and two-family dwellings
- Exempt Window awnings meeting the stated projection/support limits
- Exempt Non-fixed and movable fixtures, cases, racks, counters, and partitions under 5 feet 9 inches high
- Exempt Retaining walls not over 4 feet high, unless supporting a surcharge
- Exempt Electrical exemptions listed by the city handout include temporary decorative lighting, reinstallation of attachment-plug receptacles, and same-capacity replacement of branch-circuit overcurrent devices
- Exempt Mechanical exemptions listed by the city handout include portable heating/ventilating/cooling equipment, certain closed-system piping within equipment, replacement components not altering approval, certain refrigerating equipment, and unit refrigerating systems
- Exempt Plumbing exemptions listed by the city handout include stoppage clearing and certain leak repairs that do not involve replacing or rearranging valves, pipes, or fixtures
Note: The city states exemptions do not authorize work that violates other laws or ordinances, and separate plumbing, electrical, or mechanical permits may still be required for otherwise exempt building items. The city's handout also gives examples of common work that still requires permits, including windows, reroofing, solar, walls/fences, patio covers, additions, plumbing fixtures, HVAC, and pools/spas.
- At minimum, the city's building permit application requests property address/APN, owner information, contractor license and city business license information, applicant contact information, project type/class, valuation, square footage, and scope of work. Depending on project type, additional checklists, plans, planning approvals, grading approvals, sanitation/school-fee clearances, proxy forms, and owner-builder forms may be required.
- Building code
- The city states updated building codes took effect January 1, 2026. Ordinance No. 726 adopts the 2025 California Building Standards Code family, including the California Building, Residential, Electrical, Mechanical, Plumbing, Energy, Fire, Green Building Standards, Historical Building, Existing Building, and Referenced Standards Codes, with local amendments.
- Permit validity
- San Gabriel Municipal Code section 150.002 amends CBC section 105.5.1 so a permit becomes invalid unless work starts within 12 months after issuance, or if work is suspended or abandoned for 12 months after commencement. The building official may grant written extensions of up to 180 days each for justifiable cause.
- Owner-builder
- A homeowner may obtain a permit for work on a one- or two-family dwelling and related accessory buildings/facilities if the owner resides or intends to reside there, shows proof of residence and ownership, performs the work, and signs that no person will be employed so as to trigger workers' compensation laws. Applicant identity must be verified. The city also uses owner-builder declaration/acknowledgment forms.
- Contractor requirements
- Contractors must hold a valid California contractor's license in good standing. If they have employees, proof of workers' compensation insurance is required at permit issuance. The city also requires San Gabriel business licenses for general contractors and subcontractors working in the city, and final approval/certificate of occupancy can be delayed until city business-license fees are paid.
