Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
New Hampshire state baseline under RSA 155-A: 2021 IBC, IEBC, IPC, IMC, ISPSC, and IRC; 2018 IECC; 2023 NEC; and state-approved amendments. The municipality may administer local amendments and enforcement where authorized.
Inspection lane
Contact the town or city building official for permit submission and inspections. RSA 155-A requires an authorized local enforcement mechanism to review plans, issue permits, inspect work, and issue occupancy certificates; the state fire marshal may act on written municipal request where no local mechanism exists.
Minor-work playbook
The county's permit FAQ states that construction, repair, movement, removal, or demolition of buildings and separate electrical, plumbing, and mechanical work generally require permits, but ordinary exemptions are determined by the responsible municipality.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
Contact the town or city building official for permit submission and inspections. RSA 155-A requires an authorized local enforcement mechanism to review plans, issue permits, inspect work, and issue occupancy certificates; the state fire marshal may act on written municipal request where no local mechanism exists.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
Open planning reference ↗Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
No verified online portal was located in the reviewed public materials. Contact 603-527-5400 (county administration) and request the current application route before preparing a final submittal.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
