Summary
In the Town of Hudson, New Hampshire, fences up to eight feet tall are allowed by right in every residential district under the Zoning Ordinance's fence chapter. Anything over eight feet needs a permit, must sit behind the home's front corner, use metal-reinforced posts, and any fence or sports/tennis enclosure over 10 feet triggers Planning Board review. Fences must never block roadway or driveway sight lines.
A. No permit shall be required for any fence not exceeding eight feet in height in any residential district. ... ... C. Any fence exceeding eight feet in height must be installed adjacent to or behind the front corner of the home. D. Any fence exceeding eight feet in height must have metal or metal reinforced support posts. E. Any fence, sports/tennis enclosure, other than for agricultural uses, exceeding 10 feet in height is subject to Planning Board review. ... ... H. No fence, hedge, planting or enclosure wall shall obstruct or interfere with roadway and/or driveway sight distances as determined by the office of the Town Engineer.
Full Breakdown
Hudson's Zoning Ordinance regulates every fence, wall or similar enclosure in town except trees, shrubs and natural vegetation, under § 334-12, last amended 3-14-1995 by Amdt. No. 3 and 3-9-2010 by Amdt. No. 6. In any residential district a fence up to eight feet tall needs no building permit at all. Once a fence, including a sports or tennis court enclosure, tops eight feet, the Community Development Department requires a permit before construction, and the fence must be installed adjacent to or behind the front corner of the house rather than out at the property line, with metal or metal-reinforced support posts holding it up.
Push a fence or tennis enclosure past 10 feet, agricultural fences excepted, and the application goes to the Planning Board for review rather than a routine permit sign-off. The ordinance sets no setback distance for fences at all: a fence may sit on the lot line. What it does require is a reasonable appearance toward neighboring properties and public rights-of-way, and it flatly bars any fence, hedge or planting that blocks roadway or driveway sight distance, a call the Town Engineer's office makes on inspection.
Because fences fall inside the Zoning Ordinance, an over-height or sight-blocking fence is enforced the same way as any other zoning violation, by the Zoning Administrator and Building Inspector under the Board of Selectmen's authority.
Violations & Fines
A fence built over eight feet without the required permit, or one that blocks sight distance at a corner or driveway, is a Zoning Ordinance violation under § 181-1: a civil fine of up to $100 per day runs from either the conviction date or the date the Town gives written notice, whichever comes first. The Town may also seek injunctive relief, cease-and-desist orders or a land-use citation under RSA 676:15, :17 and :17-a as adopted at § 334-79. Appeals of a Zoning Administrator decision go to the Zoning Board of Adjustment within 30 days under § 334-81.
