Baltimore County, MD Permits — Who Issues What

One countywide building and zoning authority, legally separate from Baltimore City

Best first step

Find the approvals for your parcel, not just a generic form.

Start by confirming whether the parcel is in an unincorporated area and whether county shoreland, sanitary, floodplain, or land-division review applies. A city or village may still administer the building permit.

How to use this Baltimore County, MD County page

Baltimore County has no incorporated municipalities. County Permits, Approvals and Inspections administers building, zoning, electrical, plumbing/gas, and HVACR records countywide. A Baltimore postal address can still be in Baltimore City, so the parcel jurisdiction code—not the mailing city—controls the portal.

  • Confirm the parcel jurisdiction code is BACO / Baltimore County; a Baltimore postal city is not proof of City jurisdiction.
  • Resolve the current County zoning district from the official PAI GIS layer and review the linked district report.
  • Check floodplain, Chesapeake Bay Critical Area, historic, environmental, utilities, and road authority before siting work.
  • Separate the building record from electrical, plumbing/gas, and HVACR trade records.
  • Confirm whether a deck, accessory structure, grading, demolition, use change, or residential alteration needs plans or prerequisite approvals.
