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.
Development governed by lot occupancy / building form, not FAR (see development-standards matrix).
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.
How complete is this market? Across 134,966 parcels we answer 93.9% of the 6 questions this site is built to answer, each with a source you can check. The rest are shown as “not recorded” rather than filled in — we would rather be short than wrong.

This is the zone. What about the parcel?
Zone rules are the starting point — the answer for a specific property also depends on lot
size, overlays, existing improvements and site conditions. Run a free address lookup to see

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.
