The City of Dover's Inspection Services division, part of the Planning Department, handles building, electrical, plumbing, mechanical and fire and life safety plan review and permit issue, and enforces the building and fire codes and health regulations for a Strafford County city of around thirty-five thousand that has grown faster than any other larger city in the state. The division moved to 269 Mast Road on the ninth of June twenty twenty-five, next to the public works facility, having outgrown its old offices at the Liberty North End fire station — an address change recent enough that older directories still send people to the wrong building.
Dover's online portal is the most developed in the batch: about sixty applications for permits, plans and business licences, from utility and paving licences to driveway and excavation permits and building permits, available at any hour without entering a municipal building. Customers may use it fully, stay on paper, or work somewhere in between. The city also publishes impact fees for larger projects separately from the ordinary fee schedule — a cost that lands on development rather than on a straightforward renovation and that is easy to miss when budgeting a subdivision or a commercial build.
This guide covers the City of Dover in Strafford County. Rochester, Somersworth, Durham, Madbury and Rollinsford are separate municipalities with their own building officials, the state line lies to the east, and no New Hampshire county issues building permits in practice.
The office moved; the old address is still in circulation. Inspection Services now operates from 269 Mast Road, not from City Hall or the Liberty North End fire station — the move took effect in June twenty twenty-five. Its own line is separate from the City Hall switchboard, and third-party directories still list the health office and City Hall for building permits. Confirm the address before travelling.
What requires a building permit in Dover?
New Hampshire applies one code everywhere and leaves the enforcing to the town. Under RSA 155-A all buildings, building components and structures constructed in New Hampshire must comply with the state building code and the state fire code — there is no opting out of the standard. What varies is who administers it: a municipality takes on permitting and inspection only by adopting an enforcement mechanism under RSA 674:51, and a good number of New Hampshire towns never have. The code itself is the twenty twenty-one international building, residential, existing building, plumbing, mechanical and swimming pool codes with the twenty eighteen energy code and the twenty twenty-three National Electrical Code, all with New Hampshire amendments, in force since the first of July twenty twenty-four. So in Dover the questions are whether the municipality enforces, what it has amended, and the sixty-application portal and the office that moved to Mast Road.
Two statutory rules shape every New Hampshire project and neither is in the model code. The first is a lock on the edition: the state building code in effect when the permit application is received by the governing authority remains in effect for the duration of the work covered by that permit, so a long project is not overtaken mid-build by a new code. The second is the concurrency period: for six months after a new edition takes effect an applicant may elect to show compliance under either the old code or the new one — but not a combination of the two. Beyond that, the code draws the ordinary permit line: construction, alteration, renovation, repair, removal and demolition are covered; ordinary repairs are not.
Typically permit required
- Building, electrical, plumbing, mechanical and fire and life safety work, reviewed and permitted by the division
- Driveway, excavation, paving and utility work, on their own applications through the portal
- Impact fees on larger projects, published separately from the ordinary fee schedule
- New construction and renovation, on a permit obtained before work begins under RSA 155-A:4
- Alteration, renovation, rehabilitation, repair, removal and demolition of buildings previously erected
- Electrical, plumbing and mechanical work, by tradespeople licensed by the state
Often exempt
- Ordinary repairs that do not alter structure, egress, fire protection or building systems
- Painting, papering, flooring, cabinets and similar finish work
- Ordinary repairs that do not alter structure, egress, fire protection or building systems
- A tent of any size erected as an accessory structure at an owner-occupied one or two-family dwelling
- Painting, papering, flooring, cabinets and similar finish work
What the municipality may change, and what it may not
New Hampshire lets a municipality amend the state building code, and then puts a check on it. Local amendments are adopted by the legislative body under RSA 674:51, but since the twenty twenty-two amendment to that statute a local ordinance amending the code may not be enforced unless it has been confirmed by the state Building Code Review Board, which publishes the amendments it confirms. Issuing permits and collecting fees are not themselves amendments and need no confirmation. A municipality that has adopted an enforcement mechanism may contract the work to a local enforcement agency or a qualified third party rather than employ its own building official, and that contractor holds the same authority as a building inspector. Appeals from a local official go to the municipality's own building code board of appeals; appeals from the State Fire Marshal go to the Building Code Review Board. Beyond that, the sixty-application portal, the office that moved to Mast Road in twenty twenty-five, and the impact fees the city publishes for larger projects.
Who handles permitting in Dover?
The Inspection Services division of the Planning Department is the permitting authority inside the city, administering the New Hampshire State Building Code through the enforcement mechanism Dover has adopted and handling building, electrical, plumbing, mechanical and fire and life safety review, permit issue, code enforcement and health regulations. Planning and Community Development handles land use, the Engineering Division reviews infrastructure, the environmental department issues shoreland, wetlands and sewage approvals, and the Office of Professional Licensure and Certification licenses the trades.

Permit types
Residential permits
A Dover house project files through the portal with the trades on their own applications, and can track the permit, pay fees and book inspections in the same place. The division's inspectors carry regulatory checklists in the field and can complete inspection reports on site and share them with the permit holder in real time. Records searches run through the portal or by calling ahead, though the city notes plainly that there are not always records to be found on an older property.
How New Hampshire contractor credentials work
New Hampshire issues no general contractor licence. A builder needs no state credential to take on a house, and the statute puts the duty squarely on them anyway: the contractor is responsible for meeting the minimum requirements of the state building code and state fire code, and no municipality may be held liable for a contractor's failure to comply. The trades are licensed through the Office of Professional Licensure and Certification: electricians under the electricians' board, plumbers under the plumbers' board, and gas fitters and mechanical trades under the licensing required by RSA 153:27. In Dover the credential is checked at permit issue where the municipality enforces, and where it does not the licence requirement still applies to the tradesperson doing the work.
Commercial permits
Commercial work in Dover — the mill buildings along the Cochecho, the downtown, the waterfront redevelopment and the business parks off the turnpike — runs through the same portal with fire and life safety review inside the division rather than as a separate errand. Impact fees apply to larger projects and are published separately, so a development budget built from the ordinary fee schedule alone will be short.
The state permits that sit outside the town
Several New Hampshire approvals come from the state rather than the municipality, and they are the ones most often missed. The Shoreland Water Quality Protection Act requires a permit from the Department of Environmental Services for construction, excavation and filling within two hundred and fifty feet of a protected water body — a state permit, not a local ordinance. Wetlands work and subsurface sewage approval run through the same department. The State Fire Marshal permits, inspects and certifies buildings owned by the state, the university system and the community college system wherever they stand, and operates the State Building Permit Program for municipalities without a code enforcement mechanism that have asked for help in writing. In Dover the Cochecho and Bellamy rivers and the tidal reach towards Great Bay put shoreland and wetlands approvals from the state environmental department ahead of the local permit on much of the city's waterfront, and the mill stock along the falls keeps existing building work at the centre of the commercial file.
Dover permit costs and fees
Dover charges permit fees under the city's published fee schedule, with impact fees published separately for larger projects and the state's own approvals charged by the department that issues them.
| Item | Fee or rule |
|---|---|
| Building permit | Per the city's published fee schedule |
| Impact fees | Published separately, applying to larger projects |
| Trade permits | Electrical, plumbing and mechanical, through the same portal |
| Driveway and excavation | Their own applications and fees |
| State permits | Shoreland, wetlands and sewage approvals through the environmental department |
| Records | Searchable through the portal; not every older property has records |
Impact fees are a separate schedule. Dover publishes impact fees for larger projects separately from the fee schedule that covers smaller ones. On a subdivision or a commercial build that is a material line item, and it is not discoverable from the ordinary permit fee table. Price both before committing to a development programme.
Trade permits and who may pull them
Trade work is permitted separately where the municipality enforces, and carried out by tradespeople holding the state licence their trade requires. New Hampshire declines to enforce arc-fault protection beyond the twenty fourteen electrical requirements, whichever edition of the electrical code the state has adopted.
Permit required
- Electrical — by an electrician licensed by the state electricians' board
- Plumbing — by a plumber licensed by the state plumbers' board
- Gas fitting and mechanical — under the state licensing required by RSA 153:27
- Fire protection — under the state fire code, with the fire marshal's review where it applies
Typically exempt
- Arc-fault protection beyond the twenty fourteen electrical requirements, which is not enforced in New Hampshire
- Like-for-like replacement the adopted code places below the permit threshold
How to apply for a Dover building permit
Permitting exists locally only where an enforcement mechanism has been adopted under RSA 674:51; the code applies either way.
A local amendment is unenforceable unless the Building Code Review Board has confirmed it, and the board publishes what it confirms.
Shoreland, wetlands and subsurface sewage approvals come from the environmental department, not from the town.
Electricians, plumbers and gas fitters are licensed by the state; there is no general contractor licence, and the contractor carries the compliance duty.
The code in effect when the application is received governs the whole of the work; during a concurrency period elect one edition, not a blend.
Footing to final with the trades on their own permits, then the certificate of occupancy.
Review, corrections and what actually causes delay
Inspection Services reviews building, electrical, plumbing, mechanical and fire and life safety together inside one division, which removes a handoff that most cities keep. What delays a Dover project is a visit to the old address, a development budget without the impact fees, and a records assumption on an older property the city never held records for.
Inspections in Dover
Where the municipality enforces, inspections follow the code's sequence — footing, foundation, framing, rough trades, insulation and final — requested from the building official by permit number, with the trades inspected on their own permits and a certificate of occupancy at the end. Where the State Building Permit Program covers the work instead, inspections are booked with the State Fire Marshal's office at least forty-eight hours ahead, non-compliant work draws a written order to correct, and the re-inspection carries its own fee. Dover inspections are requested through the portal against the permit number, with inspectors completing reports in the field and sharing them with the permit holder in real time, and each trade inspected on its own permit.
