Is a Building Permit Required?

This information should be used as a guide to determine whether a permit and plans are required for projects you wish to undertake. Permits (and sometimes plans) are required to ensure that your repairs, additions, or alterations are done according to the County Codes and other applicable codes and regulations. 
Homeowners may apply for permits for ordinary repairs or construction on their owner-occupied dwelling. Separate trade permits are required for mechanical, plumbing, and electrical work and must be performed by tradesmen licensed in Anne Arundel County.
All development activities on waterfront properties that may not require a building permit including such items as at-grade patios, driveways, small retaining walls, sheds under 64 sq. ft. etc., must be reviewed for adherence to the State Critical Area Laws. Please complete a Standard Grading Plan Application form and Critical Area Worksheet. Development in the waterfront buffer may require a variance.
