Cromwell, Connecticut Building Permit Guide

In Cromwell, the Town’s Building Department on the second floor of Town Hall, 41 West Street, administers the State Building Code and issues building permits, including the mechanical work an application covers. You download the application, but it can only be submitted in person or by mail. Under chapter 99 of the Town Code the permit fee is $20 for the first $1,000 of estimated cost and $15 for each further $1,000 or part of it, and the application adds lines for plan review, a certificate fee and the state education fee.

John Egan is the Chief Building Official, working with an assistant building official. The department’s number is 860-632-3428. Cromwell has its own Health Department for septic systems and wells and a Planning and Development office for zoning and wetlands, both on the same floor of Town Hall, so most of the sign-offs a project needs are in one building.

The whole town files here; neighboring Middletown, Rocky Hill and Berlin have their own building departments.

What requires a building permit in Cromwell?

Cromwell’s Town Code adopts the Connecticut State Building Code as the Town’s building code, so the state code’s list of permitted and exempt work applies here. The Town’s application asks for electrical, plumbing, heating and air conditioning, home improvement, new home construction and swimming pool builder license numbers, which shows the range of work it covers, and the department publishes a separate process for solar installations and a requirements list for demolition.

What the town decides and what the state holds

The code itself is the 2022 Connecticut State Building Code, which the application records as effective October 1, 2022; the 2026 edition is delayed, and the filing date will decide which edition applies. Cromwell’s Town Council sets the fees in chapter 99, rewritten in full on February 8, 2017, along with the plan review charges, certificate fees, refund rules and the rule that no permit or certificate is approved on property with delinquent taxes. Zoning and wetlands are decided by the Planning and Zoning Commission and the Inland Wetlands and Watercourses Agency, and septic and well approvals by the Town’s own Health Department.

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

Cromwell building department: who handles permitting

The Building Department reviews plans, sets the final valuation of each job, issues permits and inspects. Planning and Development supports the Planning and Zoning Commission, the Zoning Board of Appeals, the Conservation Commission, the Inland Wetlands and Watercourses Agency and the Aquifer Protection Agency, and its staff handle zoning and wetlands enforcement. The Health Department permits on-site septic systems and private wells and reviews additions and other changes on septic lots. The Fire Marshal, Engineering, the Sewer and Water departments and the Tax Department each sign off where the Town’s construction checklist calls for them.

Permit types

One building permit application, revised in March 2026, serves most jobs. It records the estimated cost including labor and materials, the building, plan review, certificate and state fees, whether the fee includes mechanicals, the owner and applicant, the purpose of the permit and the license or registration numbers of every trade involved, and both the owner (or authorized agent) and the applicant sign. The department’s forms page adds the workers’ compensation affidavit, the solar permitting process, the demolition requirements and the construction checklist.

Residential permits

For houses, townhouses and their accessory structures, the Building Official decides whether a plan review is needed; when it is, the fee is $50 per dwelling, covering the mechanicals, additions and alterations, and resubmitted plans cost another $50. The applicant supplies the estimated value and the Building Official sets the final figure; an estimate that looks low means the permit is denied unless detailed estimates back it up. Before applying, the Town’s construction checklist asks you to collect the sign-offs that apply to the job, on each department’s own form.

On a septic lot, an addition, garage, shed, pool, finished basement or lot line change needs the Health Department’s B100a review. The plan review application asks for a plot plan showing septic and well setbacks and a code-complying septic area, floor plans before and after for interior work, the bedroom count before and after, and soil data or new soil testing where none is on file. The Health Department charges $100 per lot for a B100a review.

Commercial permits

Commercial and all other non-residential work pays a $200 plan review fee, and $200 again for resubmitted plans, on top of the $20 and $15 permit rate. The Building Official may send a project to an approved outside agency for plan review, at the applicant’s cost. Commercial jobs collect the same departmental sign-offs, and the checklist also lists the state Department of Transportation and the Office of the State Traffic Administration among the possible approvals.

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 and wetlands: Planning and Development signs off zoning and handles wetlands applications to the Inland Wetlands and Watercourses Agency.
• Health: septic permits, septic plan reviews, B100a reviews and soil tests are $100 per lot each; a well permit is $100.
• Engineering, sewer and water: sign-offs where the work involves them.
• Taxes: the Tax Department confirms taxes are paid.
• Fire Marshal: sign-off on the forms listed on the checklist; the office is at 1 West Street, 860-635-3188, the number on the Town’s checklists and the state Fire Marshal list.

Cromwell permit costs and fees

Section 99-2 of the Town Code sets the fees. The standard fee for every permit is $20 for the first $1,000 of estimated construction cost or part of it, and $15 for each further $1,000 or part of it. The department’s fee table, marked to round up, works the state education fee out at 26 cents per $1,000 of the stated value and adds it to the building fee; the code says it is not waived even on Town projects.

Worked example. A $25,000 addition is $20 for the first thousand plus 24 × $15, or $380, and the state fee is 25 × 26 cents, $6.50: $386.50. If the Building Official requires the $50 plan review and a $20 certificate of occupancy, the total is $456.50.

All fees, re-inspections included, must be paid before a certificate of approval or occupancy issues. Refunds are asked for in writing to the Building Official within six months of issue, decided by the Town Manager, and capped at 70% of the fee; certificate fees are never refunded. Permits for the Town and the Board of Education are waived, though not the state fee, and the waiver does not extend to the Cromwell Fire District or the Mattabassett District.

Trade permits and who may pull them

Cromwell’s single application covers the trades: it has a box for whether the fee includes mechanicals and spaces for the electrical, plumbing and HVAC contractors’ license numbers, the home improvement registration, the new home construction contractor number and the swimming pool builder number. Each trade is charged at the same standard rate under chapter 99. The Town’s solar instructions show the process at work: a roof-mounted system needs the building application with total panels and kilowatts, a tax approval form, the home improvement registration, the E-1 electrician’s license, a stamped structural analysis and panel, racking, wiring and roof plan drawings. Ground and pole mounts add zoning, health and sewer sign-offs and two inspections. The Town estimates one day for building review, seven for zoning and engineering and 60 to 90 days where wetlands review is needed, and the department notifies Eversource within one business day of a passed final.

The applicant certifies that they own the property or are authorized by the owner, and accepts responsibility for requesting every required inspection and the final before use. Whether an owner may do trade work personally is a matter of state law.

How to apply for a Cromwell building permit

Review, corrections and what causes delay

The Town’s construction checklist says the departmental sign-offs come before you submit the application, so a missing zoning, health, sewer or tax sign-off stops a file before it starts. A low valuation can lead to denial until detailed estimates are produced, plan review may be needed and resubmitted plans carry a second fee, and no permit or certificate is approved on a property with delinquent taxes. State law gives the department 30 days from the application date to issue or refuse a permit.

Demolition has a longer list: signed approvals from the Tax Office, Fire Marshal, Health Department, Zoning and Sewer, utility shut-off notices, workers’ compensation proof, the demolition contractor’s license, proof that neighbors were notified by registered or certified mail, an application signed by owner and contractor, an insurance certificate written for demolition under state law, and a hold harmless statement. The Health Department charges $200 for its demolition permit.

Inspections in Cromwell

Call 860-632-3428 at least 24 hours ahead for each inspection and for the final before the building is used. Inspections are made between 9:30 a.m. and noon and between 1 and 3 p.m. The applicant is responsible for requesting all required inspections, finding out their results and calling for the final.

A failed inspection costs $30 for each re-inspection. Before the final for a certificate of approval or occupancy, the construction checklist asks for the same departmental sign-offs again, and every fee must be paid. A home in a mapped flood zone may need an elevation certificate, which the Town says owners obtain from a land surveyor of their choice. Under section 99-5, a code violation can bring a fine of up to $500 a day, and working on after a stop order adds a further fine of $25 to $500 a day.
