Quick Answer: When You Need a Permit
In California, you need a building permit for any bathroom remodel that involves:
Permit required:
• Moving or adding plumbing (relocating toilet, shower, or sink)
• Electrical work (new circuits, moving outlets, adding lighting)
• Structural changes (removing walls, enlarging the room)
• Adding or moving a water heater
• Installing a new shower pan or bathtub
• Converting a half-bath to a full bath
• Any work behind walls that affects plumbing or electrical systems
No permit needed:
• Replacing fixtures in the same location (new faucet, toilet, showerhead)
• Painting and wallpaper
• Replacing flooring (tile, vinyl, etc.) without subfloor modification
• Installing new mirrors, towel bars, or accessories
• Replacing a vanity in the same location with same plumbing connections
• Reglazing a bathtub
• Replacing cabinet hardware
Why Permits Matter (Even When It's Tempting to Skip)
We understand — permits add time and cost. But here's why they're worth it:
Legal protection:
• Unpermitted work can result in fines of $500–$5,000+ per violation
• You may be required to tear out and redo unpermitted work
• Insurance may not cover damage from unpermitted modifications
Resale impact:
• Buyers' inspectors flag unpermitted work
• Lenders may refuse to finance homes with unpermitted additions
• You'll need to disclose unpermitted work when selling (California law)
Safety:
• Inspectors verify proper waterproofing (prevents mold and rot)
• Electrical inspections prevent fire hazards
• Plumbing inspections ensure proper drainage and venting
The cost of a permit ($500–$2,000 for a typical bathroom remodel) is far less than the cost of fixing problems later.

Common Bathroom Remodel Scenarios
Scenario 1: Replacing a tub with a walk-in shower Permit needed? Yes — involves plumbing modifications and new shower pan/waterproofing.

How to Verify Your Contractor Is Pulling Permits
Protect yourself by verifying permits are actually pulled:
1. Ask for the permit number — Your contractor should provide this before work begins
2. Check online — Most LA-area cities have online permit portals where you can verify
3. Look for the posted permit — By law, the permit card must be posted visibly at the job site
4. Verify the contractor's license — Check at cslb.ca.gov (Times Square Remodeling: License #953868)
A licensed contractor who pulls proper permits is protecting your investment. At Times Square Remodeling, every project is fully permitted and inspected — no exceptions.
