Building, electrical, plumbing and gas permits issued by Baltimore County Permits, Approvals and Inspections, which covers the whole county (it has no incorporated towns): Towson, Catonsville, Dundalk, Essex, Parkville, Pikesville, Owings Mills, Randallstown, Perry Hall, White Marsh and the rest. Baltimore City is a separate jurisdiction with its own permit office and is not in this file; the few trade permits whose ZIP code lies wholly inside Baltimore City are left out. Grading, storm-water and use-and-occupancy permits are not counted.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
