Simsbury, Connecticut Building Permit Guide

The Town of Simsbury’s Building Department issues every building and trade permit in town, from the online permit center or over the counter at Town Hall. The fee is a flat $16.26 for each $1,000 of construction cost, rounded up, and since October 3, 2025 no permit or certificate of occupancy is issued on property with delinquent taxes or town charges.

The department works from Town Hall at 933 Hopmeadow Street, open 8:30 a.m. to 7:00 p.m. on Monday, 8:30 a.m. to 4:30 p.m. Tuesday to Thursday and 8:30 a.m. to 1:00 p.m. on Friday, with Danny Sousa as Building Official and a deputy building official. Besides the State Building Code it enforces the zoning regulations, the Historic District regulations and the town’s Oil Tank Ordinance, and it assigns street addresses. Simsbury has about 25,600 residents (Census estimate for 2025), all served by this one building office.

Avon, Canton, Granby, East Granby and Bloomfield border Simsbury and run their own building departments.

What requires a building permit in Simsbury?

Simsbury’s FAQ says permits are required before any new construction, alteration or repair begins, and it gives a list of common projects sorted by permit type. Several items that need only a trade permit also need a zoning sign-off for their location.

A new air conditioner, a ductless split or heat pump and a propane tank all need zoning sign-off for where they sit, and since May 2014 a shed under 200 sq ft still needs zoning sign-off although it needs no building permit. The town notes its list is not exhaustive and asks owners to call when unsure.

What the town decides and what the state holds

Simsbury sets its fee by Board of Selectmen ordinance, runs its own online permit center, enforces zoning and historic district rules through the same office and withholds permits on delinquent taxes. The tax rule, adopted on September 8, 2025, reaches electrical and mechanical permits and certificates of occupancy as well as building permits, and it also counts unpaid sewer fees and other town charges. The building code, the exempt-work list and the licensing of trades and building officials come from the state.

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

Simsbury building department: who handles permitting

The Building Department issues and inspects all building and trade permits. The Planning and Community Development Department, in the same building, staffs the Planning Commission, Zoning Commission, Conservation Commission acting as the Inland Wetlands and Watercourses Agency, Zoning Board of Appeals, Historic District Commission and Design Review Board, and administers the zoning regulations, the Simsbury Center Code and the Hartford-Simsbury Form-Based Code. Fire code review and the commercial fire review fee belong to the Simsbury Fire District, and septic and well approvals to the Farmington Valley Health District in Canton.

Permit types

Residential permits

Simsbury’s permit form covers building, HVAC and mechanical, plumbing, electrical and other work, and it can be filed as a blanket permit covering several trades or as separate permits. A house project uploads digital plans, though the department may ask for a paper set, and a plot plan drawn to scale showing the exterior work. The owner may apply, or an agent such as a contractor or architect with a letter of authorization. The department publishes its own guides for decks, basement finishes (one for contractors and one for homeowners), pools and demolition. The deck guide asks for joist, beam, post and footing details, footings at least 42 inches deep, ledger and flashing details, a scaled plot plan, the $25 zoning form and approval from the health district (septic) or the sewer authority.

Commercial permits

Commercial, industrial and multi-family applications add a paper set of plans for the Fire Marshal and a fire review fee of $5 per $1,000 of construction value, collected by the Building Department for the Simsbury Fire District since October 1, 2023. Where structural or mechanical review or testing services are needed, the applicant pays their cost on top of the permit fee. Projects in the town center or on the former Hartford site (Hartford North and Hartford South) follow the Simsbury Center Code or the Hartford-Simsbury Form-Based Code, and large or complex land use applications can be charged for outside consultants.

For tenant improvements and new commercial builds, Alliance handles commercial permit expediting through issuance. More on this: commercial building permits explained.

What comes before the building permit

The Zoning Compliance Review application, $25, is required for projects such as additions, decks, garages, generators, condensers and pools, and the same form later carries the certificate-of-occupancy sign-offs from the health district, sewer, Fire Marshal, zoning, wetlands, the Historic District Commission and engineering. Work in the Historic District needs a certificate of appropriateness from the Historic District Commission. In a flood zone, the town’s flood ordinance requires a development permit from the Town Planner, and a substantially improved home must have its lowest floor at or above the base flood elevation.

Demolition has its own checklist. The application is signed by the owner and a licensed demolition contractor and comes with the contractor’s insurance certificate, license and the $25 zoning form, plus a Historic District application inside the district. Before the permit is issued the town needs letters showing every utility is disconnected, a plan for any lead or asbestos abatement, a licensed exterminator’s certificate that the building is free of rodents and a hold harmless agreement; the contractor files the state Department of Public Health demolition notice separately. For an older building the department sends the legal notice to the abutters and the owners across the street, the state historic preservation office, the Connecticut Trust for Historic Preservation and the Simsbury Historical Society, and the applicant pays the notice costs.

Simsbury permit costs and fees

The Board of Selectmen amended section 70-2 of the town code on March 24, 2025, and the new rate took effect on July 1, 2025. The fee is charged on the market value of the work, materials and labor, rounded up to the next $1,000. The town’s deck guide still shows the old rate of $14.26, so use the ordinance figure.

Worked example. A $20,000 basement finish pays 20 × $16.26 = $325.20. A $19,400 job is rounded up to $20,000 and pays the same. A $200,000 commercial fit-out pays $3,252 for the permit and $1,000 in fire review fee, $4,252 in all, before any zoning or convenience fee.

Neither the ordinance nor the town’s fee announcement says whether the $16.26 rate includes the state education fee of 26 cents per $1,000, so ask the department when budgeting. Refunds are at the Building Official’s discretion, and fees for permits that have been reviewed and issued are not refunded. At the counter the department takes cash or check only; card or ACH payments go through the online center.

Trade permits and who may pull them

Trade work is charged at the same $16.26 per $1,000 rate, either on its own permit or as part of a blanket permit. The permit form asks for the contractor’s license number, and the Department of Consumer Protection licenses electricians, plumbers and heating contractors and registers home improvement and new home contractors; the department’s guide page links to the state licensing center.

How to apply for a Simsbury building permit

Review, corrections and what causes delay

The Building Official must examine everything submitted against the State Building Code, and the local Fire Marshal checks Fire Safety Code compliance where it applies; state law allows 30 days to issue or refuse. Delays in Simsbury usually come from delinquent taxes or sewer charges, a missing zoning review, a commercial set without its paper copy for the Fire Marshal, a deck or addition on a septic lot without health district approval, and an agent applying without the owner’s authorization letter. Demolition of a building of 500 sq ft or more that is over 50 years old waits for a legal notice in the Hartford Courant, published within 10 days of filing, and a 15-day objection period; an objection holds the permit until 90 days after the application was received.

Inspections in Simsbury

The permit form commits the applicant to call at least 24 hours in advance for each inspection, and the department’s residential schedule lists them in order: footing and foundation before concrete; rough plumbing, mechanical, gas and electrical, which must pass before framing can pass; a floodplain inspection where it applies; framing and masonry with fire-blocking and bracing complete; insulation; fire-resistance-rated assemblies such as garage separations; and the final. Roof underlayment can be inspected through photographs taken during the job and uploaded to the permit portal before the final is booked. The final may also need a final cost affidavit, the concrete supplier and installer form and the energy compliance certificate. For a new house the certificate of occupancy also needs an A-2/T-2 as-built survey at a scale of at least 1 inch to 40 feet, showing every structure, the elevations, utilities, well and septic, setbacks and easements.
