Windsor Locks is a town of about 12,600 people (Census estimate for 2025) on the Connecticut River north of Hartford, and its Building Department works from the Town Office Building at 50 Church Street. Mark Doody is the Building Official, and also the town’s housing code enforcement officer and ADA compliance officer. The department has kept hours of 8 a.m. to 4 p.m. Monday to Wednesday, 8 a.m. to 6 p.m. on Thursday and 8 a.m. to 1 p.m. on Friday, but the First Selectman has announced a permanent four-day schedule for Town Hall offices from November 8, 2026: 8 a.m. to 5 p.m. Monday to Wednesday, 8 a.m. to 6 p.m. on Thursday, and closed on Fridays.

What requires a building permit in Windsor Locks?

The department administers permits for residential and commercial construction under the state building code and the town’s ordinances. Its application form lists the permit types it issues: building, demolition, electrical, plumbing, roofing, HVAC, solar, pool and signs, each priced on the fair market value of the labor and material. The department also posts the state code’s list of work exempt from permits.

What the town decides and what the state holds

Windsor Locks sets its permit fees, its minimum construction values, the Fire Marshal’s plan review charge (25% of the building fee on commercial permits, under a town ordinance), its refund policy and its zoning and wetlands rules. The code is the 2022 Connecticut State Building Code for applications filed since October 1, 2022, and the department’s November 2025 letter warns that drawings not designed to the 2021 model codes as adopted will be denied at plan review. A 2026 state edition has been delayed and will apply by application date once it is in force.

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

Windsor Locks building department: who handles permitting

The Building Department reviews plans, issues permits, inspects and issues certificates of occupancy. Before a permit issues, the application form collects sign-offs from zoning, the tax and sewer offices, the health department, wetlands and the Fire Marshal. The Fire Marshal’s office reviews plans for all buildings except one- and two-family homes, with its submittals made through the Building Official’s office. The Planning and Zoning Commission and the Inland Wetlands and Watercourses Commission are advised by the town planner, a wetland agent and a consulting town engineer, and septic systems and wells come under the North Central District Health Department.

Permit types

Residential permits

The department’s list of minimum information for construction documents asks for two sets of dimensioned plans with a site plan showing every structure and its distance to the lot lines; a flood hazard plan where the lot is in a flood zone, to set the structure’s elevation above the floodplain; a foundation plan with footings, walls, anchor bolts, rebar, drainage and waterproofing; floor plans (existing and new for a renovation); elevations with finished room heights; an electrical plan showing receptacle types, switches, fixtures, disconnects, smoke and carbon monoxide alarms and panels; and a braced wall plan. The plans must give room sizes and uses, the square footage of the work, bedroom escape openings and a window and door schedule, and come with appliance installation instructions and engineered calculations for all trusses and engineered lumber.

The application form adds a tax collector’s sign-off, a copy of the trade license, workers’ compensation proof or the state waiver, and an authorized agent affidavit when someone other than the owner applies. The department posts the state’s 7A and 7B workers’ compensation waiver forms, and guides for pool barriers, generators, deck building and asphalt shingle installation.

Commercial permits

Commercial work needs four sets of signed and sealed plans, including site plans, by a design professional licensed in Connecticut, drawn to at least 1/8 inch to the foot and fully dimensioned. They must show the full means of egress to the public way, the exterior envelope with its listed installation instructions, the codes referenced, occupancy classification, construction type, sprinkler type, building area and height, and the occupant load of each room and floor. The Fire Marshal reviews building, HVAC (including commercial kitchen hoods), plumbing (gas piping, tanks and sprinklers) and electrical plans (fire alarms, egress lighting and exit signs) for new construction, renovations and additions; signs, roofing, facades and awnings skip that review. The Fire Marshal’s fee is 25% of the building fee.

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

What comes before the building permit

The permit form’s approval block shows the order: zoning, tax and sewer, health, wetlands and the Fire Marshal sign before the building permit issues, and the department posts a separate zoning review form for driveways. The Inland Wetlands and Watercourses Commission treats clearing, grubbing, filling, grading, paving and excavating within 80 feet of a watercourse or 40 feet of a wetland as regulated activity, and asks owners to call the wetland agent before doing anything they suspect is regulated; the commission meets on the first Wednesday of the month at 7 p.m. On a septic or well lot the health department signs off first.

Windsor Locks permit costs and fees

The department’s permit fee schedule, effective July 1, 2024, charges $38 for the first $1,000 of work and $16 for each $1,000 after that, plus the state education fee of 26 cents per $1,000 under section 29-263 of the General Statutes. Values are the fair market value of labor and material, but never less than the department’s minimum values. Its newer Minimum Permit Cost Valuation Schedule of June 5, 2025 raises those floors above the figures still printed on the 2024 fee sheet (for example $112 rather than $95 per sq ft for a new house, and $40 rather than $30 for a deck).

Worked example. A $20,000 job pays $38 plus 19 × $16 ($304), or $342, and $5.20 in state education fee, $347.20 in all; a commercial job of the same value adds the Fire Marshal’s 25% of the $342 building fee. Under the refund policy effective July 1, 2026, nothing is refunded once a permit is issued, under review, voided, inactive or denied; an application still marked new gets back the town fees only, not the card processing or state fees.

Trade permits and who may pull them

Electrical, plumbing, HVAC, roofing and solar work are separate permit types on the same application form, each with a copy of the trade license. At every electrical inspection the department wants the E-1 license holder on site and the panel doors removed. Gas piping is inspected rough, underground, for CSST bonding and at a pressure test, and plumbing is tested at the building sewer, drain and vent piping, shower liners, backflow devices and hydronic piping.

Trade licenses and home improvement and new home construction registrations are issued by the state Department of Consumer Protection, which offers an online lookup.

How to apply for a Windsor Locks building permit

Windsor Locks offers PermitLink and a printable application. State law in section 29-263 of the General Statutes lets an applicant file in person, by mail or by email in the manner the building official prescribes, so call 860-627-1447 to agree the route that suits you.

Review, corrections and what causes delay

The building official has 30 days from the date of an application to issue or refuse the permit under state law. In Windsor Locks a file stops when the tax collector has not signed off, when plans are drawn to an outdated code (the department will deny them), when residential plans lack the braced wall plan or truss calculations, and when a value below the minimum schedule has to be corrected. Because refunds end once review begins, it pays to choose the permit types and value carefully before filing.

Inspections in Windsor Locks

It is the permit holder’s duty to tell the department when work is ready, with at least 48 hours’ notice, and to find out the result before carrying on. The approved drawings stay on site until the certificate of occupancy, and work stays exposed until it is approved in writing. The department may make a preliminary visit to the structure and site before it issues a permit.

The required list runs from piers, footings and foundation walls before concrete, waterproofing, footing drains and anchor bolts before backfill, and the vapor retarder and under-floor work before the slab, through braced-wall framing before the air barrier, chimney hearth and firebox, rough electrical, gas, plumbing and mechanical, rough framing with fire and draft stopping, fire-rated assemblies and insulation, to the finals. In a flood zone, a registered design professional must submit the as-built elevation of the lowest floor before construction goes any further.

Windsor Locks permit search and official resources

PermitLink’s public access portal offers a property search, a permit list and a document search, and the Building Department keeps the files for older work. The portal also warns of scammers posing as town officials who ask applicants to wire permit fees: the town never asks for wire transfers, and fees are paid inside PermitLink. Windsor Locks takes part in the National Flood Insurance Program, and FEMA lists new flood maps for the town taking effect on November 13, 2026; the department’s inspection list includes the lowest-floor elevation survey for work in a flood zone.
