New Hamsphire Zoning Atlas logo

The New Hampshire Zoning Atlas is a comprehensive database and interactive online map cataloging and portraying district-level land-use regulations affecting housing construction across the entire land area of the state.

The Zoning Atlas is policy-neutral, but the maps and data linked below suggest that there is much that New Hampshire can do to adjust our zoning to help our communities to flourish, and to assist our state in attracting and retaining young people, growing families, aging seniors, and a workforce for our economy. 

Click the various links below to use the atlas, download the data, read about our methodology, review our findings, and more.

The NH Zoning Atlas is the product of a statewide effort, including a dedicated team of student researchers, data analysts, zoning experts, and experienced GIS (geographic informations systems) professionals, as well as community funding and advice and guidance from the National Zoning Atlas project.

Corrections? We froze the zoning data on June 1, 2023, and subsequently collected nearly 400,000 pieces of data from reading over 23,000 pages of NH community zoning codes.

If you see a correction, please help us by emailing us the details at zoningatlas@anselm.edu.

Meet the students who did the hard work of collecting data for the Atlas!
