Most permit applications (excluding those select types that are eligible for a walk-through process) take a minimum of three weeks to process. This is due, in part, to volume, but is primarily due to the amount of research conducted for each application. The permit must first be located to verify the current zoning, legal description, and whether any special exceptions, variances, or other types of waivers have been granted. The permit is then logged in and, depending on the type of application, routed throughout other Divisions for their comments. Once returned to the Permit Office, the permits are processed in the order in which they were received. More complex projects may take longer. Information as to the status of particular permit applications may be obtained by calling 301-952-4707 and referencing the permit number.
