New Hampshire Zoning Atlas
Please use the above link to view the NH Zoning Atlas, produced by Saint Anselm College’s Center for Ethics in Society. The Zoning Atlas is a great resource for learning about municipal zoning ordinances. The Atlas does not capture all aspects or nuances relative to local zoning ordinances. The most complete zoning information is found in each municipality's zoning ordinance. You can view the data used to better understand the Atlas here.
The Atlas's focus is on housing.
Corrections? The Zoning Atlas data is “frozen” as of June 1, 2022, after which time nearly 400,000 pieces of data were collected from reading over 23,000 pages of NH community zoning codes.
