Do I need a permit in Concord, and who pulls it?

New Hampshire has one building code for the whole state. Under RSA 155-A the State Building Code, the 2024 International Residential Code for one- and two-family homes and the 2023 National Electrical Code, each with New Hampshire amendments, applies in every city and town, and a permit is required before work covered by the code begins. What differs from town to town is the office that issues it: the state leaves permits, inspections and fees to each municipality, which is why this page starts with the Concord building department.

Who applies is more open than in some states. The code lets the owner or the owner's authorized agent apply for a building permit, and New Hampshire issues no statewide general contractor licence. The trades are another matter: electrical installations need a licensed electrician, and gas fitting and plumbing need a licence from the Mechanical Licensing Board, in each case with a permit and inspection. The statute is explicit that the contractor is responsible for meeting the code, so the usual arrangement is that the contractor doing the work pulls the permit under their own licence.

Heating and cooling in ConcordReplacing a furnace, boiler or water heater, or installing a heat pump, ductless mini split or central air conditioner, is permitted work in New Hampshire: the code requires a permit to install, alter or replace any mechanical, gas or electrical system it regulates, and only portable appliances and minor part replacements are exempt. Anything on the gas side, a gas furnace, boiler, water heater or the piping to it, is fuel gas fitting, licensed by the state's Mechanical Licensing Board, and the wiring to a heat pump, mini split or condenser is an electrical installation that needs a licensed electrician.Read more

Ask the Concord building department which permits it issues for the equipment itself; the contractor pulling them is expected to know.

New Hampshire has no separate HVAC contractor licence: the state's Mechanical Licensing Board licenses fuel gas fitters and plumbers, and oil heating technicians only on a voluntary basis, so do not expect an HVAC licence number. What you should expect is a fuel gas fitter licence on the gas work and an electrician's licence on the wiring, each with its own permit on file. The state also bars any town from restricting your choice of heating system or fuel supplier, so the decision between oil, propane, natural gas and a heat pump is yours.

If you are counting on an NHSaves rebate for a heat pump or central air conditioner, the conditions are the utility program's: a residential electric customer of Eversource, Liberty, Unitil or the New Hampshire Electric Co-op, equipment that meets the efficiency minimums, an install within the program year, and for the enhanced heat pump rebate a pre-verification before the install. A permitted, inspected installation is how the town documents the work; it does not replace the rebate paperwork.

Windows and doors in ConcordReplacing windows or exterior doors is not on the code's list of work exempt from a permit, that list is finish work such as painting, tiling, cabinets and counter tops, small detached sheds, fences and low decks, so plan on a permit in Concord. The code's own exception for ordinary repairs stops at anything that removes or changes a required means of egress, which is exactly what a bedroom window is, and enlarging or shrinking an opening alters the structure.Read more

Whether a strict like-for-like swap in the same opening counts as an ordinary repair is the Concord building department's call, so ask before assuming.

New Hampshire issues no statewide licence for window or door installers, so the permit is the record of the work: it is issued by the town under the state code, and the owner or the contractor as the owner's agent applies for it. If Concord has a historic district, the state statute leaves historic district ordinances fully in force, so exterior window and door changes inside one usually need the historic district commission's approval before the building permit issues.

Roofing in ConcordRe-roofing and roof replacement are not among the projects the code exempts from a permit, so in Concord treat a roof job as permitted work: the code requires a permit to alter or repair a building, and its ordinary-repairs exception is written for minor work, not for stripping and replacing the weather envelope. The town issues the permit under the state code, and the statute makes the contractor responsible for meeting it.Read more

The code has requirements for roof coverings, underlayment and ice barrier that the inspector checks against, and New Hampshire adopts them with its own amendments: the 2024 edition from 1 July 2026, with permits accepted under either the 2021 or the 2024 code until the end of 2026. Rather than quote them here, ask the Concord building department what it inspects for on a re-roof; the contractor pulling the permit is expected to know.

Siding in ConcordResiding a house is not on the code's list of permit-exempt work, so in Concord plan on a building permit for siding replacement. The exemption covers finish work, painting, papering, tiling, carpet, cabinets, and small accessory structures, not the recladding of a building's exterior; the Concord building department decides where the line between a patch and a replacement falls, and the contractor pulling the permit is expected to ask.Read more

No statewide licence covers siding contractors in New Hampshire, so the town's permit and inspection are the record that the work was done to code, with the contractor responsible under the statute for meeting it. If Concord has a historic district, a change of siding material or profile on a building inside it usually needs the historic district commission's approval first; the state code leaves those local ordinances in force.

Before you plan work in Concord

Concord's Building Safety Division, part of the Code Administration Division at 37 Green Street, takes every permit application through the city's Citizen Self Service permit portal: building, residential and commercial electrical, plumbing, residential and commercial mechanical, and demolition. Paper applications have been discontinued, though a kiosk in the office and staff guidance are there for anyone who prefers to apply in person, and the city asks portal users to work from Google Chrome on a computer rather than a phone. A contractor, permitting service, design professional or owner-builder registers for an account; anyone else can use the portal's public search to look up a permit. The city tells the applicant the fee after review, and it must be paid before the permit issues.

The Code Administration Division lists the codes it enforces: the 2024 International Building, Residential, Mechanical and Plumbing codes, the 2023 National Electrical Code, the 2018 energy code, the 2021 pool and spa code and the 2021 International Property Maintenance Code. Concord is one of the cities with a housing program: the Housing Division responds to complaints about existing rental housing under the city's Housing Maintenance and Occupancy Code, and the division's housing inspectors also carry building inspections. Zoning questions moved from Code Administration to the Planning Division on September 30, 2024, so a project that needs zoning relief starts there.

Frequently asked questions

Do I need a permit to replace my furnace, boiler or AC in Concord?

Yes. The New Hampshire building code requires a permit to install, alter or replace a mechanical, gas or electrical system, and only portable appliances and minor part replacements are exempt. Gas equipment is fuel gas fitting, licensed by the state's Mechanical Licensing Board; the wiring to a heat pump or condenser needs a licensed electrician, and Concord issues the permits. The contractor doing the work normally pulls them.

Do I need a permit to install a heat pump or mini split in New Hampshire?

Yes. The electrical connection is an electrical installation that needs a licensed electrician and an electrical permit from the town, and the equipment itself is mechanical work the code regulates. NHSaves rebates are the utility program's business, with their own equipment and paperwork conditions; they do not replace the permit.

Read the full New Hampshire guide
Do I need a permit to replace windows in New Hampshire?

Plan on it. Window and door replacement is not on the code's list of permit-exempt work, and the ordinary-repairs exception excludes anything that removes or changes a required egress, which a bedroom window is. Whether a same-size swap counts as an ordinary repair is the local building department's call.

Read the full New Hampshire guide
Do I need a permit to replace siding in New Hampshire?

Plan on it. Residing a house is not among the projects the code exempts from a permit; the exemption covers finish work like painting and tiling, not recladding the exterior. The local building department settles borderline cases and issues the permit.

Read the full New Hampshire guide
Do I need a permit to replace my roof in Concord?

Yes. Re-roofing is not exempt under the New Hampshire building code, so Concord will expect a building permit before the work starts, and the contractor is responsible under RSA 155-A for meeting the code's roofing requirements.

Read the full New Hampshire guide
How long is a building permit good for in New Hampshire?

Under the International Residential Code as adopted by New Hampshire (section R105.5), a permit becomes invalid if the work has not started within 180 days of issue, or if more than 180 days pass between inspections once work has begun; the building official may grant written extensions of up to 180 days at a time. An application that is filed but not pursued is treated as abandoned after 180 days.

Are building permits public record, and how do I look one up for an address in Concord?

Yes, permits are public records. Concord uses EnerGov, linked at the top of this page, where you can search by address. The recent filings table on this page shows the same public data with the street, date and permit type.

Can a homeowner pull their own permit in New Hampshire?

Often, yes. The code lets the owner apply for the building permit, and New Hampshire's licensing statutes let the owner-occupant of a single-family home do their own electrical installations and, in an existing single-family primary residence, their own fuel gas fitting: still under a permit, to code and with the town's inspection. A licence is required for anyone else doing that work. Most homeowners still let the contractor pull the permit, because the statute makes the contractor responsible for meeting the code on the work they do.

What happens if work is done without a permit?

The town can order the work stopped, opened up for inspection, corrected or removed, and the code provides penalties for building or altering without a permit. Unpermitted work also surfaces at sale, when a buyer's attorney searches the permit history. It is far cheaper to permit it the first time.
