Summary

San Jose requires a separate plumbing permit before any plumbing work begins under Municipal Code § 24.02.100, with narrow exemptions in § 24.02.130 for stopped leaks and fixture swaps that don't rearrange piping.

Except as specified in this part, no building, structure or building service equipment regulated by this title and the technical codes shall be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished unless a separate, appropriate permit for each building, structure or building service equipment has first been obtained from the building official.

Full Breakdown

San Jose's Title 24 permit chapter treats plumbing work like any other building service equipment: Section 24.02.100 bars erecting, altering, repairing or removing it without a separate permit from the building official. Section 24.02.130 carves out only two narrow plumbing exemptions, stopping a leak in a drain, waste or vent pipe (unless the fitting has to be replaced, which converts it back into permitted new work) and clearing a stoppage or fixing a leak without swapping or rearranging pipes, valves or fixtures. The technical standards enforced through that permit are the California Plumbing Code, 2025 edition, adopted by reference in Section 24.04.100.

Violations & Fines

Plumbing work done without the required permit is unpermitted construction the building official can order stopped, exposed for inspection, or corrected, and it can block issuance of a certificate of occupancy until the work is permitted and inspected.

Frequently Asked Questions

Do I need a permit to fix a leaking pipe in San Jose?
Only if you replace or rearrange piping. Section 24.02.130 exempts simply stopping a leak or clearing a stoppage, but replacing a defective trap, drain or vent pipe requires a permit and inspection.
What plumbing code does San Jose enforce?
The California Plumbing Code, 2025 edition, adopted by reference in Municipal Code § 24.04.100, with local omissions and additions listed in §§ 24.04.110 and 24.04.120.
