When you apply for a building permit to do exterior work on your property (such as building an addition or adding a deck), you must include a building plat – a plat map that includes drawings of all existing and proposed property improvements such as the house, the driveway, the deck you want to build, etc.

The plat should also show all trees that measure at least 4.5 feet above ground and have circumferences of 12 inches or more.

You may order a plat map from the Department of Consumer & Regulatory Affairs’ Office of the Surveyor. Order using the form below or online:  https://aca.dcra.dc.gov/dcracitizenaccess/ (instructions for online ordering are attached below).
