The national zoning reference

Standardized zoning. Nationwide.

Every jurisdiction writes its own code, in its own words, in a thousand-page PDF. zoneoptics reads them into one standardized database — every district, every dimensional standard, every citywide provision — cited to the exact section of the adopted code.

The record

Four layers, one standard schema

Classification

One legend for every jurisdiction

Every district is classified and coloured in the tradition of a printed zoning map — yellow residential, red commercial, violet industrial, green open space — so a page of search results reads like a zoning map rather than a spreadsheet.

Accurate to the sentence

Nothing here is estimated or inferred. Every district, standard and provision carries the ordinance section it was read from and the exact language of that clause, so any value can be checked against the adopted code before it is relied on.
