Why Plumbing Permits Matter in Los Angeles
Los Angeles County and its municipalities take plumbing permits seriously — and for good reason. A permit ensures the work is inspected by a licensed building official who verifies it meets current California Plumbing Code. Unpermitted plumbing work can: void your homeowner's insurance for related claims, fail disclosure requirements when you sell, require costly tear-out and redo during a sale or refinance inspection, and expose you to liability if a water damage event occurs.
What Plumbing Work Requires a Permit in LA?
Work that always requires a permit in Los Angeles County: whole-house repiping (supply or drain lines), water heater replacement or installation, sewer line repair or replacement, adding a new bathroom or kitchen, relocating any drain or supply line, gas line work of any kind, installing new plumbing fixtures that require new supply or drain connections, and any work that requires opening walls or floors. Note: Each city in LA County (Burbank, Pasadena, Glendale, etc.) may have slightly different requirements — we handle permits for all jurisdictions we serve.
What Doesn't Typically Require a Permit?
Minor repairs that typically don't require permits: replacing a faucet or showerhead (same location, no new connections), replacing a toilet (same location), clearing a clogged drain, replacing a garbage disposal in kind, fixing a running toilet, and replacing a P-trap or supply stop valve. When in doubt, call us — we'll tell you exactly what's required for your specific job and jurisdiction.
