Cheshire, Connecticut Building Permit Guide

In Cheshire the town’s Building Department at Town Hall, 84 South Main Street, issues building, electrical, plumbing, mechanical, sewer connection, fuel tank and demolition permits, all filed through the town’s OpenGov portal; state law lets an applicant file in person, by mail or by email in the manner the building official sets, so call 203-271-6640 if you cannot use it. Under the fee ordinance the Town Council adopted on June 13, 2024, building, trade and sewer connection permits cost $30 for the first $1,000 of work and $15 for each further $1,000, fees are never refunded, and the department asks for 10 to 14 business days’ notice for inspections in the busy season.

What requires a building permit in Cheshire?

The Building Department lists the residential and commercial work it permits, and that list includes re-roofing, new siding and replacement windows, wood and gas stoves, oil tanks, electrical service repairs and pools, whether they sit in the ground or above it. The department also warns that a building permit project will often need electrical, mechanical, plumbing or sewer permits as well, and a zoning permit.

Anything not on the list follows the exemptions in the State Building Code. Work the building code exempts can still need the zoning compliance review, which covers sheds, decks, signs and filling or grading.

What the town decides and what the state holds

The Town Council sets the fees in section 3-3 of the town code; its last amendment, adopted on June 13, 2024, took effect 21 days after publication. On October 13, 2026 the Council also adopted a new ordinance that can delay demolition of historically significant buildings by up to 150 days; it takes effect 21 days after its legal notice is published, expected in November 2026. The town’s Department of Planning and Development runs zoning, Chesprocott Health District handles septic and health approvals, and the Building Code Board of Appeals hears disputes with the building official. The code itself, and whether plans meet it, rest with the state code and the state-certified building staff.

Cheshire building department: who handles permitting

The Building Department is staffed by state-certified officials who issue building and mechanical permits and certificates of occupancy on new construction and additions. Conrad Cyr, Jr. is the Acting Building Official, working with an assistant building official, an electrical inspector and a combined assistant building official and electrical inspector. The office is on the first floor of the original Town Hall building; Engineering is on the second floor.

Cheshire permit types and application documents

Each permit is a separate OpenGov application, and the portal posts the supporting documents next to them: Workers’ Compensation Commission Forms 7A, 7B and 7C, a fillable letter of authorization, the concrete information form the state requires, a wall bracing worksheet and instructions, the sign permit procedure, the zoning compliance review form and a link to the state’s trade license lookup.

Residential permits

For houses, the Department of Planning and Development’s administrative zoning compliance review covers new single-family homes, additions, in-law apartments, decks, sheds, pools and filling or grading, and the form asks for the lot’s development standards. On a septic lot the Chesprocott Health District’s forms apply, and for roofing, siding and window permits on houses built before 1978 the district hands out the federal lead-safe renovation (RRP) rules, which require firms paid for that work to be lead-safe certified. Switching from septic to the town sewer is a sanitary sewer connection permit, priced like any other permit, with in-person inspection of the pipe and trench from the house to the curb and an as-built drawing.

Commercial permits

Commercial and industrial projects pay the same building and mechanical rates plus a Fire Marshal review fee of $5 per $1,000. New businesses, expansions of commercial or industrial buildings and new commercial, industrial or multi-family buildings go through zoning compliance first. The portal posts the Office of the State Traffic Administration’s review process for developments of 100,000 sq ft or more or with 200 or more parking spaces, and the state code’s exceptions for temporary tents.

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

Zoning compliance comes from Planning and Development, septic and well matters from Chesprocott Health District (which serves Cheshire, Prospect and Wolcott), and sewer work also involves Engineering: a $5,000 drain layer bond, a street excavation permit for digging in the road, Engineering’s own inspection of every connection to the sewer main and a sewer use fee. Once the new demolition delay ordinance takes effect, demolition of an older building will start with the Historic District Commission (see below).

Cheshire permit costs and fees

Section 3-3 of the town code, as amended on June 13, 2024, applies one scale to residential and commercial work. Residential means a one- or two-family house, including townhouses, or an accessory structure.

For example, a $60,000 addition to a house costs $30 for the first $1,000 plus 59 × $15 ($885), or $915 for the building permit, with the trade permits priced the same way on their own values. A $200,000 commercial fit-out pays $3,015 for the building permit plus $1,000 for the Fire Marshal review. The ordinance lets the Town Council waive fees for new construction of 5,000 sq ft or more assessed at over $750,000 that is wholly owned by a public charity serving the town, and for work at a disabled veteran’s home needed to meet the Americans with Disabilities Act.

Trade permits and who may pull them in Cheshire

Electrical, plumbing and mechanical (heating and air conditioning) permits, fuel tank permits and sewer connection permits are all issued by the Building Department through the portal. The department reminds homeowners to make sure every contractor holds the right license: electricians, plumbers, HVAC installers and sewer installers need a State of Connecticut license, and home improvement contractors and new home builders must be registered with the state. The portal links the state’s online license lookup so you can check, and a letter of authorization form for anyone filing on another person’s behalf.

Sewer laterals have extra steps: the permit goes through the portal, the trench and pipe on private property are inspected in person, the work needs at least two weeks’ notice for inspections, and Engineering inspects the connection at the main.

How to apply for a Cheshire building permit

Review, corrections and what causes delay

State law allows 30 days from the application for the building official to issue or refuse the permit. Much of the waiting in Cheshire comes from lead times the town publishes itself: the department asks for 10 to 14 business days’ lead time on inspections in the busy season, the sewer requirements ask for two weeks, and every department on the certificate of occupancy checklist wants at least a week’s notice. Once the new ordinance takes effect, a demolition of a historically significant building can be held for up to 150 days from the filing date, and the Fire Marshal’s review is part of every commercial file.

Cheshire inspections and closeout

Inspections need lead time: 10 to 14 business days in the busy season, and at least two weeks for sewer work. The department asks builders to follow the safeguards-during-construction chapter of the building code (Chapter 33) wherever the work could create a hazard, and to call Call Before You Dig (811 or 1-800-922-4455) before any earth removal. A failed inspection or reinspection costs $10.

Before the certificate of occupancy, the Building Official needs the signatures on the town’s certificate of occupancy checklist (updated September 2025): Planning and Zoning, the Police Department, Engineering, the Fire Marshal and Chesprocott Health District each confirm their requirements are met. All of them ask for at least a week’s notice for their inspections so problems can be fixed before the owner’s move-in date, and it is up to the owner or builder to check back with each department after its first visit.

Cheshire’s demolition delay ordinance

On October 13, 2026 the Town Council adopted, by 6 votes to 1 with one abstention, an ordinance on delaying demolition permits for historically significant buildings and structures. Its last clause says it takes effect 21 days after publication, so it is expected to apply from November 2026. It treats a building as potentially significant if it was built before January 1, 1927, stands in one of the town’s historic districts, is listed on or found eligible for the State or National Register of Historic Places, or appears in the town’s 1986 Historic Inventory.

For such a “targeted demolition” the applicant files a Notice of Intent to Demolish with the demolition permit application, in the form the Building Official prescribes, and gives a copy to the Historic District Commission. The applicant pays to publish the notice in a local newspaper between 5 and 15 days before the commission’s hearing and posts a demolition sign on the property at least 10 days before it. If the commission finds the building is not historically significant, the Building Official grants the permit once everything else is in order. If it finds the building significant, it can delay the permit for up to 150 days from the filing date, must hold at least one public meeting during that time, and can waive the rest of the delay. Inside a historic district a Certificate of Appropriateness is also required, applied for no later than the day the demolition application is filed. An optional pre-application meeting with the commission does not start any of these clocks.

Connecticut building code

Cheshire’s building staff review plans under the 2022 Connecticut State Building Code, based on the 2021 International Codes, for applications filed from October 1, 2022. The state has delayed the 2026 edition, and the date of filing will determine which edition an application falls under once it arrives.

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
