Qualified County staff are available at the Permit and Review Division to discuss your options and to help you plan and build a safe project while complying with the County Floodplain Management Ordinance.

Building permits ensure safe construction inside and outside floodplains. The Prince George’s County permitting process is designed to ensure that all construction in Prince George’s County is safe. A permit is required for all new construction and, most of the time, you must obtain a permit for repairing or replacing existing features. Before you begin construction or add-on to an existing building, find out which permits are required by contacting the Permit and Review Division.

In addition to regular building permits, special regulations apply to construction in floodways and the floodplain. No construction, including filling, is allowed in the mapped floodway without an engineering analysis that shows the project will not increase flood damage elsewhere. Any activity outside the floodplain but within a natural or man-made watercourse also requires a permit.

Homeowners who are planning substantial improvements should contact the Permit and Review Division for a residential building permit. Elevation or flood proofing may be required if you plan to substantially improve your existing structure (the cost of the improvement or add-on is 50% of the value of the existing structure). If your property is substantially damaged (50 percent of the value of the building), Federal regulations may require you to elevate or flood proof before you can rebuild.

To report illegal floodplain development or to verify that proper construction permits have been issued for a project, contact the Prince George’s County Department of Public Works and Transportation at (301) 883-5777. An inspector will investigate.
