This is the zone. What about the parcel?

Every development standard on this page shows where it came from. Figures cited to a section are quoted from Title 11 DCMR itself and verified word for word against the code text. Figures linked to an official zoning GIS record come from the DC Office of Zoning's own mapped zoning data, which is dated and re-queryable but is a summary of the code rather than the code — where a standard is banded or recently amended, the ordinance text governs. Anything we cannot source is shown as “not recorded” rather than filled in. Use permissions follow Subtitle U.
