When you don’t need a permit
Like-for-like replacement of plumbing fixtures (faucets, toilets, sinks in the same location with no piping changes) is generally exempt from a plumbing permit per CBC §105.2. This applies only when supply and drain connections remain in the same location.
When you do need a permit
Adding new plumbing fixtures (new sink, toilet, shower, or laundry connections) requires a plumbing permit. New fixtures require proper drain, waste, and vent (DWV) connections sized per the California Plumbing Code.
Rerouting plumbing lines (supply or drain) requires plumbing and potentially building permits. This includes rerouting pipes for remodels, re-piping (e.g., replacing galvanized with copper or PEX), or relocating water/drain lines. Must comply with California Plumbing Code.
Water heater replacement ALWAYS requires a permit in California, even for a like-for-like replacement. This is a California-specific requirement. Permits ensure proper installation of seismic strapping (required in CA), T&P valve discharge, gas venting (if gas), and energy efficiency compliance.
