The problem

The county records the parcel. The town zones it. Your team pieces it together, one site at a time.

01

Zoning codes are unstructured

Codes are written as documents, and the zoning map is published separately.

02

Every county is different

The same use has a different name, district and rule in the next county.

03

Rules change without notice

A moratorium can pass with a single line in a meeting packet as the only record.
