Note: work in public space is regulated by DDOT.  

For the definition of public space, see DDOT’s Public Realm Design Manual on www.ddot.dc.gov.   Public space includes all the publicly-owned property between the property lines on a street, park, or other public property, as such property lines are shown on the records of the District, and includes any roadway, tree space, sidewalk, or parking between such property lines.

Public Parking Area: “Public Parking” means that area of public space devoted to open space, greenery, parks, or parking that lies between the property line, which may or may not coincide with the building restriction line, and the edge of the actual or planned sidewalk that is nearer to the property line, as the property line and sidewalk are shown on the records of the District. This area often includes spaces that appear to be front yards with private landscaping that create park-like settings on residential streets.

 A public space permit is needed for the following:

  • Dumpsters in public space
  • Sidewalk construction and repair
  • Flag poles, planter boxes, retaining walls and fences in public space
