Permits
Permits for siding, windows and decks in Pelham
Ask first. Pelham's "Do I Need a Permit" sheet lists jobs with and without permits, but its two-column layout doesn't read reliably online, so confirm siding, window, door, porch and deck work with the town before work starts; the sheet's own advice is "WHEN IN DOUBT, CONTACT THE PELHAM PLANNING DEPARTMENT," and it notes "All permits require inspections" (Do I Need a Permit).
Where to go. Building permits come from the Planning/Building Department at 6 Village Green. We found no online filing portal; fees can be paid online, and inspections run Monday through Thursday through the Planning Office (Building Permits; Building Services).
Posted fees. The building permit fee schedule adopted February 10, 2026 and effective March 1, 2026 sets a $50 residential minimum and a $50 re-inspection, and work begun before the permit is charged double (fee schedule). The schedule doesn't clearly show a separate deck line, so ask the office what yours will cost.

State rules. Under New Hampshire law, permits and their fees are a town matter (RSA 155-A:2). The 2024 State Building Code took effect July 1, 2026, with either code set accepted through December 31, 2026; from January 1, 2027, permit requests follow the 2024 codes (state code summary). There is no state license for exterior contractors; in the Attorney General's words, "contractors do not need to be licensed." The AG's advice is a written contract with scope, materials, total price and payment schedule before work or payment, references and suppliers, proof of insurance, and suspicion of any down payment over 50% (NH AG). Contracts over $5,000 come with the contractor's RSA 359-G notice, and a homeowner must give written notice of a defect 60 days before filing suit (RSA 359-G).
Lead and asbestos. On a house built before 1978, a paid contractor who disturbs more than 20 square feet of exterior paint must be EPA-certified, and replacing windows is always covered (EPA RRP for contractors). Cement-asbestos siding removal that is hired out needs an inspection by a qualified asbestos inspector and a state-licensed asbestos contractor, and a major project needs notice to NHDES at least 10 working days ahead (NHDES asbestos).

Historic review
Historic review of exteriors in Pelham
Pelham's zoning page says "Historic Regulations can be accessed by visiting the Planning Office during normal business hours"; no district map or rules are posted online, and the zoning ordinance revised March 2026 has no historic district or demolition article (Zoning Ordinance & Development Regulations). The town, settled in 1722 and incorporated in 1746, describes residents taking pride in "reusing and restoring our historical buildings" (town history). If you own an older building, read those regulations at the Planning Office before choosing new siding, windows or a porch design.
Decks and porches
Decks and porches in Pelham
Setbacks. Section 307-12E sets "garages, decks, sheds and other accessory uses" for single- and two-family homes back 30 feet from the front line and 15 feet from the side and rear lines; small sheds of 100 square feet or less and 8 feet tall or less are exempt. Single-family lots are 43,560 square feet with the same 30/15/15 setbacks (Zoning Ordinance, revised March 2026). The town posts no deck construction guide or frost depth, so the building inspector sets the footing details.
The 50-foot wetland line. The Wetland Conservation District covers all land within 50 feet of a wetland, perennial stream or water body (Section 307-37), and "No building or structure may be located within a Wetland Conservation District area" (Section 307-41B) (zoning). The town's 2026 wetlands FAQ calls the area a "'no cut, no disturb' zone" (Wetlands FAQs). Check the plot plan before stretching a deck toward a brook or pond.
Ponds and floodplains. The 2023 Conservation Plan names Gumpas, Harris, Little Island and Long Pond (Conservation Plan). For a lot in the protected shoreland, changing an attached deck needs a state shoreland permit or permit by notification, and decks on houses that don't meet the shoreland setbacks may extend no more than 12 feet toward the water (NHDES shoreland FAQ). Zoning Article VIII adopts the Hillsborough County flood study and flood maps dated September 25, 2009 (zoning). Footing holes need a free Dig Safe ticket (811) at least 72 hours ahead, weekends and legal holidays excluded (RSA 374; Dig Safe).
Pelham's homes
From farm town to post-war suburb
Pelham had fewer than 1,000 residents in 1946 and passed 10,000 less than 50 years later, according to the town's history (town history). It now has 5,089 housing units, 4,591 of them single-family (NHES community profile, ACS 2015–2019), and about 9% were built before 1950 (NH DHHS lead data brief, April 2023). Most of the town's houses come from that growth, an age when original siding, windows and decks come due together.
FAQ
Pelham exterior questions
Do I need a permit to replace siding or windows in Pelham?
Check with the Planning Department before work starts. The town's "Do I Need a Permit" sheet covers siding, windows and doors, but its two-column layout doesn't read clearly online, and the sheet itself says when in doubt, contact the Planning Department. The 2026 fee schedule lists a fee for decks and open porches.
How close to the lot line can a deck go in Pelham?
Zoning treats decks on single- and two-family homes as accessory uses with setbacks of 30 feet from the front line and 15 feet from the side and rear lines (zoning revised March 2026).
Can I build a deck near a brook or pond?
Not within the Wetland Conservation District. It covers land within 50 feet of a wetland, perennial stream or water body, and the zoning ordinance says no building or structure may be located there. The town's wetlands FAQ calls it a no cut, no disturb zone.
Does Pelham have historic rules for older houses?
The town keeps its Historic Regulations at the Planning Office, where they can be read during business hours; they are not posted online. If you own an older building, ask there before changing siding, windows or a porch.
What does it cost me to use New England Exterior Pros?
Nothing. Asking is free for homeowners; the contractor prices the job, and the price and contract are between you and them.
