Hudson, NH Building Setbacks & Zoning: Setback Rules (2026)

Hudson's Zoning Ordinance keeps its base yard-setback figures for each district in the Table of Minimum Dimensional Requirements, which § 334-27 says is included at the end of the chapter as an attachment rather than printed inline. Where the ordinance body does set a specific, numeric setback is § 334-14B, added 3-8-2022 by Amdt. No. 7, which addresses the taller buildings allowed by the height exception in § 334-14A. Any building between 38 and 50 feet in height, the range permitted in a handful of listed industrial parcels such as the Sagamore Industrial Park, must be set back a minimum of 400 feet from any residential zone.

That 400-foot minimum is not static: it grows by 10 feet once the building's footprint reaches 100,000 square feet, and by another 10 feet for every additional 100,000 square feet after that, applied at a fractional rate, so the ordinance's own example puts a 190,000-square-foot footprint at an extra 19 feet of setback on top of the base 400. 1, the general dimensional requirements that do appear in the printed text, add related but narrower rules: accessory storage sheds must sit to the rear of the main building, the minimum buildable lot area may contain no slopes over 25% and must exclude wetlands, and frontage is measured along the sideline of a Class V or better street. None of those sections substitute for a per-district front/side/rear setback table, which stays in the unprinted attachment.
