St. Louis plumbing permits: City-certified contractors only
In the City of St. Louis, plumbing permits are issued only to licensed plumbing contractors certified by the city, with a $30 application fee plus a fee schedule; fixtures are among the listed examples. Mechanical, plumbing and electrical permits are separate trade permits, so a bathroom with new plumbing and a new fan circuit needs two. Angi adds that the city requires permits for all major renovations and bases the fee on total cost, about $190 to $193 for a typical bathroom.
Checking a St. Louis plumber's license
Missouri has no statewide plumbing license, so the City's Plumbers and Drainlayers Board licenses master and journeyman plumbers. The board pages have no public contractor search; call the Building Division at (314) 622-3313, or use the city's permit search by address to see what has been filed on your house. Ask for proof of insurance too. Plumbing-only repairs: plumber in St. Louis.
The oldest housing we cover: lead and hidden problems
St. Louis has the oldest housing of any city we track: the Census Bureau's median year built is 1939 or earlier, 86.2% of units predate 1980, and 57.9% were built in 1939 or earlier. The EPA's lead-safe renovation rule requires certified firms when renovation disturbs lead-based paint in homes built before 1978, which covers almost every bathroom in the city. Put a contingency in the contract for what demolition finds. Water or mold behind the tub: water damage restoration in St. Louis and mold removal in St. Louis.
Grab bars and help for older St. Louis homeowners
The City's Senior Minor Home Repair Program, run through the St. Louis Area Agency on Aging, covers grab bars, ramps and basic plumbing and electrical repairs for City homeowners 60 and older; clients may pay part of the cost. Call (314) 612-5918. For broader health and safety repairs, the Healthy Home Repair Program serves owner-occupants with at least 2 years of ownership at or below 80% of area median income, but the city warns of a waitlist with a significant delay; the Home Repair Hotline is 314-657-3888.
