Figures marked official zoning GIS record come from the jurisdiction's own zoning map layer, not from the text of the code. That record is dated and linked above, and it is a summary of the ordinance rather than the ordinance itself — where a standard is banded or was recently amended, the code text governs. Figures citing a section are quoted from the code directly.

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.
