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.
By-right FAR varies by building type: Non-Residential 0.5
Read from District of Columbia Zoning Regulations of 2016 (Title 11 DCMR), effective through 2026-04-03. Amendments adopted after that date (most recent 2026-07-17) are not yet reflected.

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.
