Do I need a permit for a bathroom remodel in Los Angeles?
Answered by Netanel Presman, General Contractor (CSLB #1105249) · Updated
Short answer
In the City of Los Angeles, a bathroom remodel requires a building permit from LADBS any time you move plumbing fixtures, add electrical circuits, alter the ventilation, or remove a wall. A pure fixture-swap (same-location toilet, sink, vanity, tub) typically does not. Any work that triggers Title 24 compliance for ventilation or lighting also triggers a permit.
In detail
LADBS (Los Angeles Department of Building and Safety) applies the Los Angeles Municipal Code + California Residential Code to residential remodel work. The tripwires for a bathroom permit:
- Plumbing relocation — moving the shower, toilet, sink, or tub more than a few inches requires a plumbing permit and a rough-in inspection.
- Electrical additions — any new circuit (recessed lights, heated floor, vent fan upgrade) requires an electrical permit. Existing GFCI-protected receptacles can be replaced without a permit.
- Mechanical (HVAC / vent fan) changes — a new or relocated exhaust fan with ducting triggers a mechanical permit.
- Structural changes — removing or relocating any wall, adding a pocket door through a partition, or enlarging the bathroom footprint.
Typical LA bathroom remodel permit fee structure (2026):
- Plumbing permit: $225-$475 depending on number of fixtures
- Electrical permit: $200-$400 depending on circuits added
- Mechanical permit: $150-$250
- Building permit for structural: $400-$1,500+ depending on valuation
Inspections usually include rough plumbing, rough electrical, framing/insulation (if walls were opened), and final. Scheduling inspections through LADBS is typically 3-7 business days out.
Unpermitted bathroom work is the #1 issue flagged by home inspectors at resale in LA. Legalizing retroactively costs 2-3x the original permit fees plus potentially opening walls for inspection.
