Zoning
Plain-language zoning references for architects and building designers — districts, floor area ratio, setbacks, height and lot coverage — with the local ordinance always authoritative.
Zoning governs what can be built on a site before a single line is drawn: the use, the bulk, and the position of a building relative to its lot lines — the floor area ratio, setbacks, height, and lot coverage that shape a scheme during feasibility, massing, and entitlements.
The pages below explain each concept in plain language with typical, illustrative ranges. Every number varies by municipality and by district; the governing zoning ordinance and official zoning map for your specific parcel are always authoritative.
