Middletown, Connecticut Building Permit Guide

In the City of Middletown, the Building Division of Public Works issues building, electrical, plumbing and HVAC permits. You fill in the City’s online application, then email or post the plans and papers and pay by check; nothing is reviewed until the payment and every required document have arrived. The fee is $28.26 for the first $1,000 of work and $15.26 for each further $1,000.

The division works from the second floor of City Hall at 245 deKoven Drive, open 8:30 a.m. to 4:30 p.m. on weekdays, under Chief Building Official Dean Lisitano. Middletown is a consolidated city of about 48,400 people (Census estimate for 2025), so one building office covers the whole municipality, from downtown on the Connecticut River to Westfield and Maromas.

Cromwell, Portland, Durham, Middlefield, Haddam and Berlin border Middletown and permit through their own building officials.

What requires a building permit in Middletown?

Middletown’s ordinance (chapter 120 of the Code of Ordinances) requires a separate permit for each building, structure or sign that is built, enlarged, altered, removed, relocated or demolished, and a separate permit for each trade on each building: electrical, elevator, plumbing and heating, air conditioning and refrigeration, and oil burner work. The Building Division also publishes the code’s list of work that is exempt, and a common-questions sheet for backyard projects.

What the city decides and what the state holds

The City sets the fee ordinance, the check-only payment rule, inspection booking and local rules such as the surveyor’s plot plan; the code, the exempt-work list and all licensing 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

Middletown building department: who handles permitting

The Building Division of the Public Works Department receives every permit application under section 120-1 of the city code. The Land Use Department (Planning and Zoning, the Inland Wetlands and Watercourses Agency, the Zoning Board of Appeals and zoning enforcement) signs off on site plans and zoning first. The Health Department reviews septic plans and does the soil testing for new systems, and the Water & Sewer Department issues the permit to connect to or repair city water and sewer lines.

Permit types

Residential permits

On the online form you tick every trade the job involves. A new house needs the most paperwork. Section 120-12 requires a plot plan prepared and sealed by a Connecticut registered land surveyor, showing the front, rear and side yards. Only the foundation is authorized at first; the surveyor then recertifies the plot plan with the foundation as built, and the rest of the house is approved once the Building Official finds it complies with zoning. Plot plans must also show the finished first-floor elevation and the center line of the street, and the code asks for the first floor to sit two feet above the street pavement wherever possible, or a grading and drainage plan where it cannot.

The new-home plan review checklist asks for the Department of Consumer Protection new home construction registration number, proof of workers’ compensation, a site plan that matches the building plans, full plans and sections, and energy compliance details under the 2021 codes.

Commercial permits

Commercial work files on the same form with the property type marked commercial. For large jobs the general contractor or the owner can take a blanket permit that covers every subcontractor. A sign that hangs over a street, alley or other public way needs a $10,000 surety bond and a certificate of at least $150,000 in liability insurance on file before its permit is issued. New non-residential buildings go through a Land Use site plan, with a minimum fee of $300, and designs that need the Design Review and Preservation Board are filed there too (no charge for a building review, $25 for a sign).

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

Land Use takes a site plan application for new homes, additions and accessory structures. Its fees are $100 for the first dwelling unit and $50 for each additional unit, $50 for an accessory dwelling unit, and $20 for additions and accessory structures such as pools, garages, decks and sheds, which need a GIS image showing the structure’s size and distance from the lot lines. Lots on well and septic may need a B100 application to the Health Department, and section 120-2 bars a permit for a new building, a use change or an addition that cuts into the septic area unless public sewer is available or the Health Department has issued its permit. Work in the upland review area around wetlands and watercourses goes to the Inland Wetlands and Watercourses Agency, and its 2026 decisions include single-family houses as well as large commercial sites. Land Use also has a new zoning code that took effect on August 19, 2026.

Middletown permit costs and fees

The fee rule is in section 120-3 of the Code of Ordinances, last amended on June 2, 2025 by Ordinance No. 04-25. The fee is based on the cost of the work, materials and labor, sworn to by the owner or set by the Building Official if the estimate looks low. Owners doing their own work must still add a fair market cost for labor.

Worked example. A $20,000 kitchen remodel pays $28.26 for the first $1,000 plus 19 × $15.26 ($289.94) for the remaining $19,000, a total of $318.20, with any electrical or plumbing permit charged separately on its own cost. The City’s own example is a $1,500 job, which pays $43.52 because the extra $500 counts as a full thousand.

The state education fee of 26 cents per $1,000, which the Building Official collects and sends to the state, is not shown as a separate line on the City’s fee sheet or ordinance table; the ordinance makes even nonprofits whose fees the Common Council waives pay that education fee.

Trade permits and who may pull them

Electrical, plumbing and HVAC permits come from the Building Division on the same online form, each with its own fee on its own estimated cost. Contractors must email a copy of their Connecticut license and a certificate of liability insurance showing workers’ compensation; without workers’ compensation they file the state waiver from the Forms section. Permits connected to a building project, mechanical ones included, must be fully paid and issued before any inspection can be booked.

The Department of Consumer Protection licenses electricians, plumbers and heating contractors, and registers home improvement and new home construction contractors; its online lookup confirms a license before you sign.

How to apply for a Middletown building permit

Review, corrections and what causes delay

Connecticut law gives a building official 30 days from the application to issue or refuse a permit, and in Middletown the application only counts as complete when the check and the paperwork have arrived. The usual hold-ups are a missing license or insurance certificate, an owner form that is not notarized, plans not sent with a job that needs them, and a new-home set missing items from the City’s checklist. Demolition has its own sequence: utility shut-off letters, a certified letter to the Middlesex County Historical Society, a letter to the Connecticut Trust for Historic Preservation, notice to Planning and Zoning and to the neighbors, Health Department approval of an environmental assessment, and for a building 50 years or older a newspaper notice with a 10-day objection period; an 8-foot fence must be inspected before demolition starts.

Inspections in Middletown

Inspections are booked by phone only, on 860-638-4870; emailed requests are not scheduled. The division books 7 to 10 days ahead, and in summer it can be two weeks or more, so the inspection dates belong in the project schedule. A part of the job that fails twice costs $75 before a third visit is booked.

For one- and two-family homes and additions the City lists these inspections: footings or piers before concrete, wall rebar, foundation waterproofing and footing drains, rough framing with windows and doors in, rough electrical, heating, air conditioning and plumbing with underground conduit, the permanent electrical service, gas piping and pressure test, insulation before cover, and a final for the certificate of occupancy or approval letter, which needs the duct blast and blower door test results.

Roofs are no longer inspected on site. To close a residential or commercial roofing permit, email photographs of the drip and rake edge, taped seams, ice and water shield, the stripped deck, underlayment, flashing, every finished roof area and proof of no more than two layers, with the address and permit number.

Middletown permit search and official resources

For copies of past permits, plans or certificates of occupancy, ask the Building Division on 860-638-4870 or file a public records request through the City’s FOIA request portal. Flood zones come from FEMA’s maps: Middletown takes part in the National Flood Insurance Program, with a current effective map date of February 6, 2013, and the zoning code bars new houses in the special flood hazard area and requires a floodplain development permit from the Director of Land Use for other work there.

Middletown building permit FAQ

Who issues building permits in Middletown?

The City’s Building Division, part of Public Works, at 245 deKoven Drive, 2nd floor. It issues building, electrical, plumbing and HVAC permits; call 860-638-4870.

How much is a building permit in Middletown?

$28.26 for work up to $1,000 and $15.26 for each further $1,000 or part of it, so a $20,000 job pays $318.20.

Do I need a permit for a shed or fence?

Not a building permit for a shed of 200 sq ft or less or a fence of 7 feet or less, but call Land Use on 860-638-4590 because zoning approval may still apply.

Can a homeowner pull a permit?

Yes. An owner doing the work files a notarized 7B form with the application and the check; an owner applying for a hired contractor files a 7A form.

How far ahead are inspections booked?

Usually 7 to 10 days, and sometimes more than two weeks in summer. Book by phone only, after the permit is paid and issued.

Can I build a new house in the flood zone?

No. Middletown’s zoning code does not allow new residential construction in the special flood hazard area; any other development there needs a floodplain development permit, and a substantially improved home must have its lowest floor one foot above the base flood elevation.
