Manchester, NH zoning map & districts

Manchester's zoning ordinance forms Title XV (Land Usage) of the Manchester Code of Ordinances, administered day to day by the Planning & Community Development Department, with a Planning Board handling subdivision and site plan review and a separate Zoning Board of Adjustment hearing variances and special exceptions. Like every New Hampshire municipality, Manchester regulates land use under the state's enabling statute, RSA 674, and must comply with New Hampshire's 2022 statewide accessory dwelling unit law (RSA 674:73), which requires the city to permit at least one ADU by right on lots holding a single-family home. The city currently has an active Zoning Ordinance Steering Committee working on a rewrite of the code, so developers should confirm whether a parcel's applicable standards reflect the ordinance currently in force or a pending amendment.

The code City of Manchester Zoning Ordinance

Manchester zoning map

The city publishes its zoning map at City of Manchester, NH - Official Ordained Zoning Map (24x36, effective March 1, 2026) .

Manchester's Planning & Community Development Department maintains the official zoning map and the Title XV ordinance text; the City Clerk's office processes rezoning petitions.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Manchester

Manchester's most distinct land-use feature is the Millyard, the 19th-century mill complex along the Merrimack River that has been redeveloped into a dense mix of office, residential, and institutional uses — including the University of New Hampshire's Manchester campus and Southern New Hampshire University's continuing-education offices — under standards tailored to adaptive reuse of the historic mill buildings rather than greenfield construction.

Manchester zoning — common questions

How do I find the zoning district for a property in Manchester, NH?
Manchester's Planning & Community Development Department maintains the official zoning map alongside Title XV of the Code of Ordinances; the Assessor's parcel lookup can help confirm a lot's district before requesting a formal zoning verification.
Can I build an accessory dwelling unit in Manchester?
Yes. New Hampshire's statewide ADU law (RSA 674:73) requires Manchester, like all NH municipalities, to allow at least one accessory dwelling unit by right on a lot with an existing single-family home, subject to the city's own size and parking standards.

The city has an active Zoning Ordinance Steering Committee working on updates to Title XV. Developers evaluating a project timeline should check whether a pending amendment or rezoning could affect their parcel's district before relying on current standards.
