Plumbing permits for other places in Austin and San Antonio. Each permit office keeps its own file, so the numbers are not added together.
Source: City of San Marcos GIS: CoSM BuildingPermits (Planning/CoSM_BuildingPermits FeatureServer layer 0, from MyPermitNow), read 20 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.
Building and trade permits the City of San Marcos, Texas issues inside city limits: new homes and commercial buildings, remodels, additions, pools, fences, decks, solar, demolition, plumbing, mechanical, electrical, sign and fire-system permits. Lawn irrigation, right-of-way, road closure, special event, watershed, site and grading permits, Texas State University and city projects, and certificates of occupancy in the same file are not counted. Kyle, Buda, New Braunfels and unincorporated Hays, Caldwell and Guadalupe counties run their own permit offices and are not in this file, and neither is San Marcos, California.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
