How Rockville compares with other cities

From our cross-city data studies: the same measure, read the same way, for every city we cover.

Nearby permit data

Electrical permits for other places in Washington, DC. Each permit office keeps its own file, so the numbers are not added together.

How these numbers are made

Source: City of Rockville MGO permit map layer (MGO_Permit_View, ArcGIS), read 20 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.

Building, trade, fence, sign and fire-protection permits the City of Rockville issues inside the city limits. Montgomery County's Department of Permitting Services covers the rest of the county, so a Rockville mailing address outside the city is not in this file. Plumbing and gas-service connections that WSSC Water permits are not in it either.

  • The city's permit layer names a contractor company on only about a third of permits; many others list a permit expediter or the owner as applicant, which we don't treat as the contractor.
  • The layer has no issue date, so a permit is dated by the day its case was opened; cases still under review, awaiting payment or approved but not yet issued are not counted.
  • The layer's job value is zero on every permit and it has no final inspection date, so we show no costs and no time to final.
  • Rockville moved to its current permit system (MyGovernmentOnline) in late October 2021; older permits are not in the layer.
  • Gas appliance hook-ups (stoves, ranges, dryers) that the city files as mechanical permits are counted as plumbing (gas line) work; furnace, air-conditioner and heat-pump jobs are HVAC.
  • Fire sprinkler and alarm permits, signs and commercial tenant fit-outs are counted under Other.

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