The Town of Fairfield's Building Department, on the second floor of Sullivan Independence Hall at 725 Old Post Road, enforces the Connecticut State Building Code for a coastal town of around 66,000 people between the largest city in the state and the Sound. Permit applications are accepted online only, through the City Squared system, and the public counter keeps two short windows — half past eight to half past 10 in the morning and half past three to half past four in the afternoon — while inspection scheduling, property searches and code questions go by phone to the department directly.
The name needs settling. Fairfield County survives as a name on maps, but Connecticut abolished county government in 1960, so there is no Fairfield County building department; the Town of Fairfield is one of the county's towns, with its own building official, its own Town Plan and Zoning Department and its own zoning regulations, rewritten and effective from September 2025. Zoning compliance applications also go in online, and the planning director's department is the town's floodplain administrator as well.
This guide covers the Town of Fairfield. Bridgeport, Westport, Easton and Trumbull are separate municipalities with their own building officials, and Fairfield County has had no government since 1960.
Over 4,000 properties sit in the flood zone. Fairfield has more than 4,000 properties in the federal flood zone, and the Town Plan and Zoning Department, as floodplain administrator, applies its own Flood Mitigation Regulations. Any improvement or repair costing more than half the value of the structure must bring it up to flood standard, damage of any origin counts towards the half, and every new work proposal in the zone files a substantial damage estimate form.
What requires a building permit in Fairfield?
Connecticut has one building code and no town may amend it. The State Building Inspector and the Codes and Standards Committee adopt the Connecticut State Building Code jointly under section 29-252 of the General Statutes, with the approval of the Commissioner of Administrative Services, and section 29-253 makes it the building code of every town, city and borough in the state. The edition in force is the 2022 Connecticut State Building Code, which has governed every permit applied for since the first of October 2022 and is built on the 2021 international building, residential, existing building, mechanical, plumbing, energy and swimming pool codes with Connecticut amendments, together with the 2020 National Electrical Code. A 2026 edition built on the 2024 model codes was drafted to take effect in July 2026, but the legislature's Regulation Review Committee declined to approve it that April and its effective date is delayed; the 2022 code governs until a new one is approved, and when the change comes it will turn on the date of the permit application. So Fairfield neither adopts nor amends the code — it enforces it through a building official licensed by the state — and the practical questions are the local process, the zoning and wetlands approvals that come before a building permit, and the online-only filing rule and the flood regime along the shore.

What the town decides and what the state holds
Locally, what stands out is the online-only filing rule, the Town Plan and Zoning Department that comes first, and the flood mitigation regulations that govern thousands of properties along the shore.
Connecticut has one State Building Code: the code itself sets which work needs a permit and which is exempt, every town’s building official is licensed by the State Building Inspector, and there is no county government. Connecticut rules
Who handles permitting in Fairfield?
The Fairfield Building Department is the permitting authority inside the town, enforcing the Connecticut State Building Code through a state-licensed building official. The Town Plan and Zoning Department reviews zoning compliance, administers the flood mitigation regulations as floodplain administrator and staffs the planning and zoning commission, the Conservation Department handles inland wetlands and the coastal review, the fire marshal reviews plans alongside the building official, and the Department of Consumer Protection registers and licenses contractors statewide.

Permit types
Residential permits
A Fairfield house project files zoning compliance online with the Town Plan and Zoning Department — most single-family and small multi-family work, including pools, garages and sheds, is reviewed administratively — then the building permit through City Squared with the trades on their own permits. In the beach and marsh neighbourhoods the flood regime governs the design from the start: a renovation priced above half the structure’s value becomes a flood-standard rebuild, and the substantial damage estimate form goes in with any new work.
Commercial permits
Commercial work in Fairfield — the Post Road corridors, the university campuses and the railway-station districts — files online with sealed drawings after zoning review under the regulations rewritten in 2025, with the fire marshal's review; mixed-use projects are filed as commercial. Above the threshold limits the independent structural review applies as everywhere in the state.
What comes before the building permit
In Fairfield the shoreline, the tidal marshes and the Mill and Ash Creek corridors put the flood mitigation regulations and coastal site plan review at the front of the file, the Conservation Department reviews the wetland edges inland, and the historic districts in the town centre and Southport add their own review.
Connecticut has no general contractor licence: the Department of Consumer Protection registers home improvement and new home construction contractors and licenses the trades. Connecticut rules

Call 1-855-478-4290 →Fairfield permit costs and fees
Fairfield charges building and trade permit fees on the cost of construction: since April 2024, $58.26 for the first $1,000 of value and $16.26 for each further $1,000, a figure that includes the state’s 26-cent education fee, rounded up to the nearest dollar. The town emails a payment request after review, and zoning compliance fees are paid separately to Town Plan and Zoning.
| Item | Fee or rule |
|---|---|
| Building permit | $58.26 for the first $1,000 of construction value, $16.26 for each further $1,000 (from April 1, 2024) |
| State education fee | 26 cents per $1,000 of declared value, remitted to the state |
| Zoning compliance | Separate fee at Town Plan and Zoning, filed online |
| Trade permits | Separate electrical, plumbing and mechanical fees |
| Flood-zone work | Substantial damage estimate form with any new work; elevation certificate where required |
| Pool permit | With the pool enclosure agreement and the required inspection list |
Half the value, and damage of any kind counts. In the flood zone the number that decides a Fairfield renovation is the value of the structure. Improvement or repair costing more than half of it triggers a flood-standard rebuild, and the town counts flood, fire and wind damage repair towards that half. A budget that ignores the rule is not a budget.

How to apply for a Fairfield building permit
No building permit can be issued until the zoning enforcement officer certifies the work complies. Wetlands permits come from the town's inland wetlands agency, coastal site plan review runs through zoning, and septic approval comes from the local health department.
The 2022 Connecticut State Building Code governs until the delayed 2026 edition takes effect; the application date fixes which one applies.
Home improvement or new home construction registration from the Department of Consumer Protection, and the occupational licence for each trade.
Section 29-263 requires the application to come from the owner or the owner's authorised agent; the building official reviews the plans, the fire marshal also reviews them where the Fire Safety Code applies, and the state education fee is charged on the declared construction value.
The building official must issue or refuse the permit within 30 days of the application; if the plans do not comply, the refusal must be in writing with reasons. Projects above the threshold limits also need an independent structural review.
Footing to final, trade inspections as the town requires, then the certificate of occupancy under section 29-265.

Get a free quote →Review, corrections and what actually causes delay
The Building Department reviews for the State Building Code with the fire marshal alongside; Town Plan and Zoning reviews zoning compliance and the flood regime first, online. What delays a Fairfield project is a paper application, a shoreline renovation priced without the half-value rule, a pool or generator filed on the old forms the town replaced in 2025, and a fire marshal or health approval nobody took in person.
Inspections in Fairfield
Inspections follow the code's sequence in every town — footing, foundation, framing, rough electrical, plumbing and mechanical, insulation and final — requested from the building official by permit number, with the trades inspected on their own permits. Work that passes final receives a certificate of occupancy under section 29-265, without which a new or altered building may not be occupied; on a project above the threshold limits the architect and engineer of record and the general contractor also sign a statement of professional opinion that the finished work substantially matches the approved plans. Fairfield inspections are scheduled by telephone with the Building Department against the permit number, with each trade on its own permit and the pool inspection list followed in order; the certificate of occupancy follows the final, with the zoning and flood sign-offs closed alongside.

Is there a Fairfield County building department?
No. Connecticut abolished county government in 1960. The Town of Fairfield's own Building Department at 725 Old Post Road is the authority inside the town.
Can I file a paper application?
No. Fairfield accepts building permit applications online only, through City Squared, and the application does not proceed until Town Plan and Zoning, the Conservation Department and, where applicable, the Historic District Commission have approved it. The fire marshal (140 Reef Road, 203-254-4720) and the Health Department (203-256-3020) are not yet online, so their approvals are still obtained in person. Inspections, property searches and code questions go by phone to the Building Department.
What is the 50 per cent rule?
In the flood zone, improvement or repair costing more than half the value of the structure must bring it up to flood standard, and damage repair of any origin — flood, fire or wind — counts towards the half.
Which code applies?
The 2022 Connecticut State Building Code, uniform statewide. The 2026 edition is delayed and does not yet apply.
Have the zoning regulations changed?
Yes. New zoning regulations took effect in September 2025. Confirm which setbacks and standards apply before relying on an older approval.
Does a pool need anything beyond the permit?
Yes. Fairfield requires its pool enclosure agreement and follows a required pool inspection list, both updated in 2025.
