Permits
Fence permits in Hudson
A permit for every fence. Hudson's Building Department answers the question directly: exterior additions "such as a deck, pool, fence, shed, or garage require a building permit" (Building Department FAQ). There is no height cutoff in that answer, so a short picket run along the front walk is treated the same way as a tall privacy fence. The same FAQ lets above-ground pools, decks and sheds skip the plot plan; it says nothing either way about fences, so ask what drawing to send.
Filing and fees. Applications go in through the town's file upload link, by email, by mail or in the drop box, fees can be paid online (Permits & Applications). The Application Fee Schedule revised 06/15/2023 carries no line for fences; it shows a $30 minimum charge and a $250 charge for working without a permit, and the FAQ says fees vary by permit type, so call Inspectional Services for the figure (fee schedule).

New Hampshire basics. Towns set their own permits and fees under RSA 155-A:2. The state's 2024 codes took effect July 1, 2026, either code set is accepted through December 31, 2026, and from January 1, 2027 every permit request follows the 2024 codes. The Attorney General notes that "contractors do not need to be licensed" in New Hampshire, so ask for references and proof of insurance, sign a written contract before paying anything, and be wary of a deposit over 50% (NH AG). More on our New Hampshire rules page.
Before the auger comes out. Under RSA 374:51, notice goes to Dig Safe at least 72 hours ahead, not counting weekends or holidays, and the dig area is premarked in white; a ticket is good for 30 days. Dig Safe says property owners and contractors are both required by law to notify it (Dig Safe), and its homeowner brochure lists fencing among the projects to call about; call 811 (Dig Safe homeowner brochure). A homeowner digging on their own lot is spared the civil penalty in RSA 374:55, not the duty to give notice. The notice rule in RSA 374:51 covers digging within 100 feet of an underground facility.

Height and placement
Height limits, setbacks and corner lots in Hudson
No posted fence height. We found no fence height cap or corner sight-line rule in what Hudson publishes, so ask the Building Department before ordering 8-foot panels or fencing close to an intersection. For distances from lot lines, the FAQ points to the Table of Minimum Dimensional Requirements in § 334-27 of the Zoning Ordinance (Building Department FAQ); an October 2024 zoning board agenda refers to a 15-foot side setback in the R-2 district, a figure aimed at buildings rather than fences (ZBA agenda).
Where the line really is. A stone wall or a tree row is not always the boundary. A survey, or the plan on file with the town, settles it before posts are set. New Hampshire also has a spite fence statute: a fence that unnecessarily exceeds 5 feet and is put up to annoy the people next door is a private nuisance under RSA 476:1.
Pool fences
Pool fences in Hudson
Asked how tall a pool fence must be, Hudson's FAQ gives a one-line answer: "48 inches" (Building Department FAQ). The pool itself is permitted separately, at $50 for an above-ground pool and $75 for an in-ground pool on the schedule revised June 15, 2023. Gates, latches and gaps fall under the swimming pool code New Hampshire adopts as part of its building code. Federal CPSC guidance, which is advice rather than law, suggests no gap a 4-inch sphere can pass and gates that swing away from the water and close and latch on their own (CPSC Pub. 362).
Wetlands and flood zones
Historic districts and wetlands in Hudson
No historic district. Hudson's list of boards has no historic district commission, so there is no design review of fences on historic grounds (Boards and Committees).
The 50-foot buffer. The Wetland Conservation District, amended March 12, 2024, sets "a fifty-foot-wide buffer around wetlands and surface waters for residential uses" (§ 334-35). Structures there are allowed only as conditional uses; an accessory structure for an existing house needs a Planning Board Conditional Use Permit, written comment from the Conservation Commission and proof there is no practical spot outside the district (§ 334-36). Fences are not named, so a back-lot run toward a brook or a pond edge is a question for the Planning office before the layout is final.
Floodplain and ponds. Floodplain covers over 2,000 acres, about 11% of Hudson, according to the town's Natural Resources chapter, and development in a special flood hazard area needs a floodplain permit from the Town Engineer (floodplain ordinance). The town's natural resources chapter also notes that Ayers, Ottarnic and Robinson Ponds come under the state Shoreland Protection Act (Natural Resources chapter).
Hudson's homes
Mostly post-war houses on suburban lots
The 2020 Census counted 10,080 housing units in Hudson: 81% single-family, 17% multi-family and 2% manufactured homes (Population and Housing chapter). Only about 9% of the housing was built before 1950, according to a state lead data brief from April 2023 (NH DHHS).
With so few pre-war houses, most Hudson fence work is a first fence on a ranch or colonial lot, or swapping out an aging wood or chain link run for vinyl or aluminum.
FAQ
Hudson fence questions
Does Hudson require a permit to put up a fence?
Yes. The Building Department FAQ lists a fence alongside decks, pools, sheds and garages as exterior additions that require a building permit. Paperwork can be sent through the town's file upload link, by email or mail, or left in the drop box, and fees can be paid online.
What does a fence permit cost in Hudson?
The Application Fee Schedule revised June 15, 2023 has no separate fence line, so call Inspectional Services for the amount. The same schedule sets a $30 minimum charge and a $250 charge for working without a permit.
How tall does a pool fence have to be in Hudson?
The town FAQ answers 48 inches. Pool permits on the 2023 fee schedule are $50 for an above-ground pool and $75 for an in-ground pool.
Can I fence near a brook or pond in Hudson?
Check first. Hudson's Wetland Conservation District keeps a 50-foot buffer around wetlands and surface waters for homes, and accessory structures there need a Planning Board Conditional Use Permit. The ordinance does not name fences, so ask the Planning office whether your fence line counts.
What does it cost me to use New England Fence Pros?
Nothing. Asking is free for homeowners; the contractor prices the job, and the price and contract are between you and them.
