Do I need a permit for plumbing fixture or repiping in Rockville?

Permit likely required

Most likely yes. Plumbing fixture or repiping usually requires a permit in Maryland. Confirm the specifics with Rockville.

Plumbing services require a State Board of Plumbing license outside Baltimore County and WSSC areas (Business Occupations and Professions 12-301 and 12-103). The owner exemption for plumbing in one's own residence does not cover the final connection to a public or private water or sewer system (Business Occupations and Professions 12-301(b)). Plumbing is outside the Maryland Building Performance Standards; plumbing permits follow the State Plumbing Code or the local plumbing code. Work that moves or replaces pipes, rather than swapping a fixture, alters the plumbing system itself and is not covered by fixture replacement exemptions. Pipe work normally requires a plumbing permit, a pressure or air test, and a rough in inspection before walls are closed, and many jurisdictions require a licensed plumber to pull the permit.
