Residential permits the City of Worcester's Department of Inspectional Services issues inside the city: building, electrical, gas, plumbing and mechanical permits for houses, two-families and triple-deckers and other apartment buildings. Commercial, mixed-use, school and municipal permits in the same files are not counted. Shrewsbury, Auburn and the other towns around Worcester run their own permit offices and are not in these files.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
