Concord, NH zoning map & districts

As New Hampshire's capital, Concord carries a meaningful share of state-government and institutional land use around the State House complex, which shapes downtown development differently than in a typical city of its size. The City of Concord Zoning Ordinance is administered by the Planning Division under RSA 674, with a Planning Board reviewing subdivisions and site plans and a Zoning Board of Adjustment handling variances; the city completed a major downtown Main Street redesign narrowing the roadway and widening sidewalks to encourage pedestrian-friendly mixed-use infill.
