Do I need a permit for my plumbing project?
Well, the short answer is, yes. Plumbing repairs do not need a permit, however, many replacements do need permitting. Reality kicks in when we try to define wat is a repair versus a replacement. Is a new toilet a replacement or a repair, how about a shower head? I have not had any clear response from the CSLB about how best to define repair over replacement.
Clearly however, there are some projects where a permit is definitely required. Water heaters, gas lines, sewer replacements, repipes, additional fixtures, anywhere that structural change is needed, these projects all need permits.
According to the Universal Plumbing Code (UPC) 503.0
"It shall be unlawful for any person to install, remove or replace or cause to be installed, removed or replaced any water heater without first obtaining a permit from the Authority Having Jurisdiction to do so"
