Maryland building departments
This Maryland directory covers 24 Census county equivalents and local building-department guides. Maryland’s statewide building standards are enforced through local jurisdictions. County and municipal zoning, site, stormwater, and sediment controls can be separate approvals.
How permitting works in Maryland
Statewide building standards with local enforcement. A county name is a geographic index, not a promise that the county government issues every building permit. Many projects are handled by a city, town, township, borough, parish, regional office, or independent city.
Source-backed state research
Maryland Department of Labor, Building Codes Administration
Maryland adopts statewide building standards and gives local jurisdictions time to amend and adopt the new codes for local enforcement. The state publishes a county-by-county directory of local codes and contacts.
