Do you need a permit for replacing a fixture?

• A. Yes
• B. No
• C. Only for large fixtures
• D. Only in commercial

Answer: (B)

Permits are meant for work that changes the plumbing system or adds new connections. A simple fixture replacement that uses the same rough-in, same drain and vent paths, and same water supply connections is considered a repair rather than an alteration. In that scenario, there’s no new risk introduced to the system that the permit process is designed to protect, so a permit is typically not required. If you relocate the fixture, change its size or type, or modify the drainage/venting or supply lines, then a permit would usually be needed. Always check local code, but for a like-for-like swap with no piping changes, no permit is generally required.
