Ten county research doors

Each page links the county registry of deeds, city or town offices and state mapping and permit resources.

Municipal zoning is the key

Identify the exact city or town, then confirm zoning, subdivision, legal lot status and utilities with local officials.

Septic and wells need permits

NHDES reviews septic systems and some subdivisions; check private wells and wetlands separately.

Flood, wetlands and shoreland

Screen FEMA flood maps and state wetlands and shoreland rules where relevant.
