On October 9, 2026, 63 permitted projects in the City of St. Louis were still at the point where plumbing is awarded.

St. Louis ranks 23 of 25 markets Builtie covers for plumbing, behind North Little Rock (77 projects).
A project counts when its permit was issued in the last four years, the build is still inside the stage when plumbing is awarded, and the job is big enough to be worth quoting: at least $5k of plumbing work. Trade sub-permits are grouped into their parent project, so this is a count of projects, not permits.

What the St. Louis data covers
The data is the City of St. Louis's own building permits. Neighbouring cities issue their own permits and are not in this count. St. Louis joined the feed recently, so every project counted here was permitted in the last 90 days and the counts will grow as the history fills in. St. Louis County is a separate permit office.
