Clinton, Connecticut Building Permit Guide

The Clinton Building Department at Town Hall, 54 East Main Street, reviews plans, issues building and trade permits and inspects the work, and applications go in through the town’s OpenGov system as PDF files. The fee is $25 for the first $1,000 of job value and $12 for each further $1,000, plus the state education fee, and since January 1, 2025 every electrical, plumbing and heating job needs its own permit priced on its own cost.

What requires a building permit in Clinton?

Clinton’s Building Department issues permits and makes inspections for new and renovated buildings, electrical, plumbing, heating and air conditioning work, demolitions, and the installation or removal of gas and oil tanks. Propane tanks and generators also need a plot plan showing the location (and, for a generator, the direction of the exhaust).

What the town decides and what the state holds

The technical rules and the exempt-work list are the State Building Code’s. Clinton decides the rest. The department sets its own fee schedule and filing rules, the Town Code sets a fee waiver for older and disabled owners and the land use fees, and two town code sections can hold a permit back: no permit is issued on a subdivision lot that does not front an accepted street until the access road has its binder course, and no permit is issued on a property with delinquent real estate taxes unless the work repairs a condition that impairs the occupants’ health and safety. The Planning and Zoning Commission’s regulations, revised through July 10, 2026, add coastal site plan review and flood rules along the shore.

Clinton building department: who handles permitting

Richard Pleines is Clinton’s Building Official. He reviews building and site plans and points applicants to the other agencies they need. Zoning, wetlands and the zoning board are handled by the Land Use office, and septic and well approvals come from the regional Connecticut River Area Health District in Old Saybrook.

Clinton permit types and application documents

Every Clinton application, whether building, electrical, plumbing or HVAC, needs a certificate of insurance or workers’ compensation affidavit and a copy of the contractor’s license. Documents are uploaded as PDF files, and the department does not treat an application as complete until the files are in, the fee is paid and the zoning, wetlands and health approvals have been obtained.

Residential permits

New house, addition, second floor or garage: approvals from health, zoning and inland wetlands; two complete paper sets of drawings plus PDF copies showing the foundation plan, floor plans, wall sections from the bottom of the foundation to the roof with framing sizes, and front, rear and side elevations; a description of the insulation, roofing and windows; and separate plumbing, electrical and HVAC applications. A new house also needs a bond lodged with Public Works for a curb cut on a town road, or the state’s approval on a state road.

Deck: health, zoning and wetlands approval, a wall section showing the attachment to the house, a floor plan, framing plans and footing locations. Bathroom or removing a wall: existing and proposed floor plans, with the replacement beam size for a load-bearing wall. Accessory building over 200 sq ft: much the same as a garage.

Building or remodeling a home here? Alliance handles home building permits, so the crew isn't waiting on the counter.

Commercial permits

Commercial projects, including buildings of three or more families, may pay a Fire Marshal review fee on top of the building fee, and the Building Department works closely with the Fire Marshal’s Office. Commercial and multi-family development, like new homes, ends with a surveyed final as-built plan that must be approved before the certificate of occupancy.

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: a zoning permit ($50) from the Land Use office; an accessory structure of any size needs zoning approval, and a fence over 7 feet needs a zoning permit.
• Inland wetlands: the Inland Wetlands Commission meets on the first Tuesday of each month at 7 p.m. in Andrews Memorial Town Hall, and its applications are filed in the same OpenGov system.
• Health district: on a well or septic lot the Connecticut River Area Health District reviews the plan (its forms include the B100a application and the permit to construct). Converting a seasonal cottage to year-round use needs a winterization permit from the Director of Health (Chapter 432).
• Coastal site plan review: see below.
• Driveways and town roads: a driveway apron permit from Public Works for any driveway meeting a town road, and an excavation permit for digging in the town right-of-way.

Clinton permit costs and fees

The Building Department’s 2025 policies and fee sheet, signed by the Building Official, sets the building fee; since January 1, 2025 electrical, plumbing and heating work is priced on separate permits, each on its own construction value, and the building permit covers only work such as foundations, framing, windows, doors and insulation. The state education fee is not part of the town rate: the sheet adds 26 cents for each $1,000 of construction value for the State Code Education Fund.

For example, a $30,000 addition pays $25 plus 29 × $12 ($348), or $373, plus $7.80 in state education fee: $380.80. Under Chapter 296 of the Town Code, building permit fees are waived for an owner-occupied single-family home where a record owner is 65 or older or disabled, for handicapped access work, roofing, siding, storm windows and doors, and plumbing, electrical, heating or air conditioning work. A refund is possible only while the permit is unexpired (180 days from issue) and goes to whoever paid.

Trade permits and who may pull them in Clinton

Clinton treats each trade as a separate permit. Since January 1, 2025 the Building Official has required separate electrical, plumbing and heating permits on every project, each carrying its own cost of construction, so a kitchen remodel with new circuits and a relocated sink means three applications. Every trade application carries the contractor’s license and a certificate of insurance or workers’ compensation affidavit; licenses and home improvement and new home construction registrations are issued by the state Department of Consumer Protection.

The department’s workers’ compensation rule spells out what an owner signs. A property owner doing all the work and hiring no trades signs Form 7A. An owner doing part of the work and hiring trades, even trades not listed on the application, must show workers’ compensation cover or a notarized Form 7B.

How to apply for a Clinton building permit

Review, corrections and what causes delay

State law gives the building official 30 days from the date of application to issue or refuse a permit. Clinton does not review an application until every document, fee and outside approval is in, so the usual hold-ups sit outside the Building Department: a health district review on a septic lot, a wetlands decision that waits for the monthly commission meeting, a coastal site plan, or a curb-cut bond for a new house. The town’s preferred channel is OpenGov; state law also lets an applicant file in person, by mail or by email in the manner the building official sets, so call the office if you cannot use the portal.

Work already done without a permit can be legalized with an “after-the-fact” permit. Plans are usually waived, the fee is based on today’s fair market value of the work, and the work must meet the code in force now. Finishes may have to be opened up, and the certificate of approval notes that rough inspections were not performed.

Clinton inspections and closeout

The department’s inspection list, not all of which applies to every project, runs: footings before concrete is poured; foundation wall reinforcement (with a concrete affidavit); waterproofing and footing drains; wall sheathing before the exterior wrap; the slab vapor barrier and radon stand pipe; rough electrical, plumbing, HVAC and gas piping; structural framing; insulation; and the final. A deck is inspected at the footings before concrete, at the framing with flashing in place before decking, and at the final.

A new house closes out with the health district’s permit to discharge, an as-built plan showing underground tanks, utilities and a zoning data table, blower door and duct leakage results, a RES check or equal energy report, a water test and radon test on well water, the concrete affidavit, engineered lumber certificates, equipment manuals and, in a flood zone, an elevation certificate for the finished building. The final as-built plan must be approved before the certificate of occupancy is signed, and the town asks for it at least one week before any closing.

Connecticut building code

Clinton applies the 2022 Connecticut State Building Code, based on the 2021 International Codes, to applications filed from October 1, 2022. The 2026 edition is delayed, and once it takes effect the filing date will decide which edition applies.

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

Coastal site plan review and flood zones in Clinton

Section 18 of Clinton’s zoning regulations, effective October 6, 2025, puts every building, use and structure in the town’s coastal boundary through coastal site plan review, filed with the Planning and Zoning Commission or Zoning Board of Appeals together with the zoning or other land use application. The exemptions follow state law: exterior changes and minor additions to existing buildings and detached sheds or garages are exempt except in or within 100 feet of tidal wetlands, coastal bluffs and escarpments, beaches and dunes; residential decks, walks, pools, docks and detached accessory buildings are exempt except in or within 100 feet of tidal wetlands; interior work is exempt.

Section 17 governs the flood zones. Any development in a special flood hazard area needs a floodplain development permit first, which lapses if construction does not start within 180 days. In A and AE zones a new or substantially improved home must have its lowest floor, basement included, 1 foot above the base flood elevation, with utilities also 1 foot above it; in VE and coastal AE zones the building must sit at least 25 feet landward of mean high tide, with the lowest horizontal structural member 1 foot above the base flood elevation and the space below left open.

Clinton permit search and official resources

Clinton keeps land use, building, fire and health files on each property in two places. Documents from before June 2022 are in the Docuphase (Treeno) system, reached from the town website under How Do I, Find, Property Files and searched by street name; permits and documents from June 23, 2022 on are in OpenGov, using the Search link in the upper right corner of the portal. Clinton has taken part in the National Flood Insurance Program since 1980, and its current FEMA flood maps date from February 6, 2013; the Planning and Zoning Commission administers the Section 17 flood rules and may delegate that role to the Zoning Enforcement Officer, with support from the Town Engineer.
