What this page can and can't show

  • ✓Permits the county issued, by kind of work, month and ZIP code.
  • ✓How long a permit takes from issue to the county's final inspection.
  • ✓Which permits finished or are still open.
  • ✓What the job was declared at on the permit.
  • Who did the work. The county's file doesn't name contractors, so we can't rank, compare or profile firms here.
  • Street addresses or owners. We publish counts and permit rows without them.

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.

Hiring someone here?

The permit file can't tell you who does good work. Ask for the contractor's license number and look it up at the Maryland Home Improvement Commission, then ask the county whether they pulled the permit for your job.

How these numbers are made

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 We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.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.

  • The county's files name no contractor, so there are no contractor lists, rankings or firm pages for Montgomery County.
  • Declared value is filled on building permits only; electrical and HVAC permits carry no job value, so costs are shown only for building work.
  • Plumbing permits are issued by WSSC Water, not the county, so plumbing barely appears here (a few gas-appliance jobs on mechanical permits).
  • Solar counts come from electrical permits whose description mentions solar or photovoltaic panels.
  • Decks count with garages and sheds. A final date is the county's final inspection date; a permit at Stop Work counts as open.

Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
