The City of Rochester’s Building & Licensing Services department at 33 Wakefield Street (603-332-3508) handles all building, electrical, plumbing and similar permits for a Strafford County city of around 34,000 in the Seacoast’s northern reach, on the Cocheco, along with the city’s licensing. Zoning Board of Adjustment applications are filed with the Planning & Development Department in the same building (603-335-1338).
The name needs settling. This is Rochester in New Hampshire, a city of 30-odd thousand in Strafford County; considerably larger cities of the same name exist elsewhere in the country, with their own building departments, their own adopted codes and processes that have nothing to do with this one. A search that lands on one of those produces a confidently wrong answer about permit fees, code editions and submission requirements alike — and New Hampshire's framework, where the state building code is uniform but local enforcement is optional, is not a framework those cities share.
This guide covers the City of Rochester in Strafford County, New Hampshire, including the Gonic and East Rochester villages within it. Dover, Somersworth, Barrington, Farmington and Milton are separate municipalities with their own building officials; the cities of the same name in other states are unrelated; and no New Hampshire county issues building permits in practice.
Building and licensing share one department; zoning board applications do not. Building & Licensing Services issues the building and trade permits and handles licensing, while variance and appeal applications to the Zoning Board of Adjustment are filed with Planning & Development at the same address. Settle any zoning relief the project needs before the building permit application, and bring the whole project to the first enquiry.
What requires a building permit in Rochester?
In Rochester the questions are whether the municipality enforces, what it has amended, and the one department that covers building permits, trade permits and licensing.

What the municipality may change, and what it may not
Locally, what stands out is the one department covering building permits and licensing, and the Cocheco river corridor that shapes the older centre.
Every building in New Hampshire must meet the state building and fire codes (the 2024 codes since July 2026). Only towns that have adopted an enforcement mechanism issue local permits, and any local amendment must be administrative and confirmed by the state. New Hampshire rules
Who handles permitting in Rochester?
Building & Licensing Services is the permitting authority inside the city, administering the New Hampshire State Building Code through the enforcement mechanism Rochester has adopted and issuing building, electrical, plumbing and similar permits alongside the city’s licences. Zoning Board of Adjustment applications go to the Planning & Development Department. The State Fire Marshal permits state, university and community college buildings, the environmental department issues shoreland, wetlands and sewage approvals, and the Office of Professional Licensure and Certification licenses the trades statewide.

Permit types
Residential permits
A Rochester house project takes the building permit and the trade permits from Building & Licensing Services, with electrical and plumbing work carried out by state-licensed tradespeople; any variance goes to the Zoning Board of Adjustment through Planning & Development first. The city’s older housing in the centre and the villages carries the existing building questions, while the outer parcels bring septic and well work through the state environmental department rather than the city.
Commercial permits
Commercial work in Rochester — the downtown, the Route 11 corridor, the industrial park and the airport shared with neighbouring towns — runs through Building & Licensing Services for the permits and any licence the use needs, with zoning relief through Planning & Development. The state fire code applies alongside, and the fire marshal’s pre-construction review reaches projects on the state’s own list.
The state permits that sit outside the town
In Rochester the Cocheco and Salmon Falls rivers bring the state environmental department's shoreland and wetlands approvals ahead of the local permit on the affected frontage, and the outer parcels' reliance on wells and septic puts the state's subsurface approval in the file before the building permit.
New Hampshire has no general contractor licence; the contractor carries the duty to meet the state codes, and the trades hold state licences. New Hampshire rules

Call 1-855-478-4290 →Rochester permit costs and fees
Rochester charges building and trade permit fees under the city's schedule through the same department, with zoning and licensing fees alongside and the state's approvals charged by the department issuing them.
| Item | Fee or rule |
|---|---|
| Building permit | On the declared construction value, per the city's schedule |
| Trade permits | Electrical, plumbing and similar, from the same department |
| Zoning | Zoning board applications through the Planning & Development Department |
| Business licensing | Where the use requires it, through the same department |
| State permits | Shoreland, wetlands and sewage approvals through the environmental department |
| Fire review | State fire code review where the project reaches it |
This is not the Rochester most searches find. There are much larger cities called Rochester elsewhere in the country. Their fee schedules, adopted code editions and submission requirements have no application here, and neither does their state framework. A quote built from the wrong city's tables will be wrong in both directions, and the error is common enough to be worth ruling out before any number is relied on.
Trade permits and who may pull them
Permit required
- Electrical — by an electrician licensed by the state electricians' board
- Plumbing — by a plumber licensed by the state mechanical licensing board
- Gas fitting — by a gas fitter licensed by the state mechanical licensing board
- Fire protection — under the state fire code, with the fire marshal's review where it applies
Typically exempt
- Arc-fault protection beyond the 2014 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 Rochester building permit
Permitting exists locally only where an enforcement mechanism has been adopted under RSA 155-A:3; the code applies either way.
A local amendment may cover only administrative matters, 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 trade inspections as the town requires, then the certificate of occupancy where the town issues one.
Review, corrections and what actually causes delay
The department reviews for the state building code, with the state fire code alongside. What delays a Rochester project is a fee or requirement imported from a same-named city elsewhere, zoning relief sought after the building set was drawn, and a rural parcel where the state’s septic approval was left until after the design.

Get a free quote →Inspections in Rochester
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 48 hours ahead, non-compliant work draws a written order to correct, and the re-inspection carries its own fee. Rochester inspections are requested from the department against the permit number, with each trade inspected on its own permit and the certificate of occupancy issued at the close.

Which Rochester is this?
Rochester in Strafford County, New Hampshire, a city of around 34,000 on the Cocheco. The much larger cities of the same name elsewhere are unrelated jurisdictions.
Who issues building permits here?
Building & Licensing Services at 33 Wakefield Street (603-332-3508), which handles building, electrical, plumbing and similar permits. No New Hampshire county issues building permits in practice.
Do I go elsewhere for a zoning question?
For zoning relief, yes: variance and appeal applications to the Zoning Board of Adjustment are filed with the Planning & Development Department, in the same building at 33 Wakefield Street (603-335-1338). Building and trade permits come from Building & Licensing Services.
Which code applies?
The New Hampshire State Building Code — the 2024 international codes with the 2018 energy code and the 2023 electrical code, in force since the first of July 2026.
Who approves a septic system?
The state environmental department approves subsurface sewage disposal; the city does not. The approval belongs in the file before the building permit.
Do I need a licensed contractor?
New Hampshire issues no general contractor licence, but electricians, plumbers and gas fitters hold state licences and the contractor carries the compliance duty by statute.
