Source: dataMontgomery: Residential Permit, Commercial Permits, Mechanical Permits and Electrical Building Permits (Department of Permitting Services), read 19 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.
Building, electrical and mechanical permits issued by the Montgomery County Department of Permitting Services, which covers the county outside the cities that run their own building offices: Silver Spring, Bethesda, Potomac, Germantown, Clarksburg, Chevy Chase, Olney, Wheaton, Takoma Park and the rest. The cities of Rockville and Gaithersburg issue most of their own building permits, so permits inside those cities are largely missing; a Rockville or Gaithersburg mailing address in this file is usually just outside those cities. Plumbing and gas-service permits are issued by WSSC Water, not the county, and are not in the file.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
