When a permit is required
Permit triggers and exempt work for La Mirada
La Mirada states a building permit is required to build, modify, remodel, repair, or demolish any building or structure, including garages, open patio covers, fences, accessory buildings, carports, and kitchen or bathroom remodels. Separate electrical, plumbing, mechanical, pool, grading, sewer, and miscellaneous permits are required for the corresponding work categories. Work exempt from permit is listed by Los Angeles County Title 26 through Title 29 exemptions.
- Exempt One-story detached accessory buildings such as tool sheds, storage sheds, playhouses, or shade structures not over 120 square feet, not over 12 feet high, and with roof projection not over 24 inches
- Exempt Certain fences and monument signs not over 6 feet, subject to material and setback limits, except pool barriers
- Exempt Retaining walls retaining not more than 4 feet and not supporting surcharge or certain liquid storage
- Exempt Decks, walks, and driveways not more than 30 inches above grade, not over a basement or story below, and not part of an accessible route
- Exempt Prefabricated pools for Group R-3 occupancy that are less than 18 inches deep or do not exceed 5,000 gallons and are entirely above adjacent grade; pool safety barriers and similar devices are not exempt
- Exempt Painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work where disabled-access requirements do not apply
- Exempt Minor electrical repairs such as replacement of lamps, switches, receptacles, sockets, and similar devices
- Exempt Plumbing leak repairs and drain clearing where no trap, drainpipe, soil, waste, or vent pipe is replaced or rearranged
- Exempt Portable heating, ventilating, cooling, and evaporative units, plus certain like-for-like mechanical component replacements
Note: Los Angeles County states separate plumbing, electrical, and mechanical permits may still be required even when building work is exempt, and all exempt work must still comply with zoning, code, and other applicable laws and ordinances.
