Trumbull, Connecticut Building Permit Guide

The Trumbull Building Department at Town Hall, 5866 Main Street, reviews plans, issues building and trade permits through the town’s OpenGov portal and inspects the work. Residential work costs $20 for the first $1,000 of value and $10 for each further $1,000, plus a $10 processing fee, a certificate of occupancy fee and the state education fee, and no permit is approved while property taxes or sewer charges on the lot are overdue.

What requires a building permit in Trumbull?

The department’s permit handout says a building permit must be obtained before construction, alteration or repair other than ordinary repairs, and it names decks, window replacements, wood or pellet stoves and prefabricated sheds over 200 sq ft among the work that needs one. Electrical, plumbing, heating, air conditioning and oil tank work done with a building permit needs its own separate permit for each trade.

What the town decides and what the state holds

Chapter 5 of the Trumbull Municipal Code adopts the State Building Code as the town’s building code and adds the local layer. Section 5-3 sets the fee schedule, last amended by Town Council resolution in April 2014; section 5-6 withholds approval of a building application on any property with delinquent taxes or sewer charges unless the building official certifies an emergency; and section 5-5 imposes a demolition review on older buildings. At its March 2026 budget hearing the department reported that its permit fee research did not call for changes to the town schedule. The code itself and the plan review against it remain the work of the state-licensed building official.

Trumbull building department: who handles permitting

The Building Department reviews construction documents against the State Building Code, issues the permits, monitors projects while they are built, carries out the final inspection and issues the certificate of occupancy; it also answers fire dispatch calls to judge whether damaged buildings can be occupied. Robert Dunn is the Building Official. Planning and Zoning on the second floor signs off on building permits, and the Fire Marshal on the main level reviews commercial plans.

Trumbull permit types and application documents

Applications go in through the online portal, and the department’s handout lists what goes with them: a completed application, a certificate from the Tax Collector that no taxes are owed, proof of workers’ compensation from contractors (a homeowner files the workers’ compensation affidavit form) and the approvals of any other department the project needs. Zoning permits need at least a scale plot plan, some need a full A-3 survey by a licensed surveyor, most building projects need architectural drawings, and some need an engineer’s stamp.

Residential permits

A homeowner or the homeowner’s representative with written authorization may apply. The department publishes its own guides for basements, decks, generators, pools, snow load and solar panels (a solar PV supplement goes with the application). A prefabricated shed application must include the maker’s data sheet showing a 30 lb per sq ft snow load and wind rating, with anchors for 110 mph winds and no plastic fasteners. When a permitted alteration or addition is done, the whole house must have smoke and carbon monoxide detectors. A second kitchen in a house or outbuilding in a single-family zone is not allowed, and an accessory apartment needs a meeting with zoning staff first.

Commercial permits

Commercial building and trade work is priced on a higher scale and closes with a $25 certificate of occupancy or approval. The Fire Marshal reviews all plans for new commercial buildings and for renovations of existing ones, charges its own plan review fee by floor area, and says its review can take up to 30 days. The Building Department releases the permit only after the plans are corrected to the Fire Marshal’s comments and both offices’ fees are paid. The Fire Marshal also posts temporary tenant permit forms, one of them for Westfield, and a tenant change of name form.

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

What comes before the building permit

Trumbull puts the approvals in a fixed order. Inland Wetlands approval comes before a zoning permit, and the zoning permit comes before the building permit. Zoning is not needed for re-roofing, re-siding or same-size window and door replacement, minor interior work, demolition, chimney liners or foundation repairs outside the flood zone. Sewer approval is needed for any structure on or connecting to public sewers, Engineering approves curb, sidewalk and driveway work in the road, and the Health Department must approve most work on a septic lot that involves digging, such as deck footings, or adds load to the system.

Trumbull permit costs and fees

Fees are set in section 5-3 of the municipal code. Every permit also carries a $10 processing fee and the state education fee of 26 cents per $1,000 of value (demolition excepted), and Town-owned buildings and the fire districts are exempt from the town’s building fees, though the department’s fee sheet says the state education, processing and certificate of occupancy fees still apply to Town-owned work.

For example, a $50,000 residential addition costs $20 plus 49 × $10 ($490) for the permit, $10 processing, $13 state education fee and a $10 certificate of occupancy: $543 before any trade permits. The code sets a $40 minimum for trade permits, while the department’s posted fee sheet lists $60 for residential and $80 for commercial trade permits; the code is the adopted schedule. A septic permit from the Health Department is $200 for a new system and $150 for a repair.

Trade permits and who may pull them in Trumbull

Electrical, plumbing, heating, air conditioning and oil tank work is permitted separately from the building permit and priced on its own scale, and the department’s fee sheet adds a $10 certificate of approval for each commercial trade permit. The handout is clear on who may do the work: a homeowner may do his own work if he lives in the house and does not rent out any part of it, and still needs the permits; anyone else doing permitted work must be licensed and registered with the State of Connecticut. Generators should be installed by a licensed electrician with a permit.

The handout points homeowners to the Department of Consumer Protection’s online license lookup to check a contractor, and to the home improvement guaranty fund that protects work by registered contractors. Fire alarm and sprinkler plans for commercial buildings go to the Fire Marshal (203-452-5080), whose fees for those plans run from $100 for under 5,000 sq ft to $1,000 for 75,000 sq ft or more.

How to apply for a Trumbull building permit

Review, corrections and what causes delay

The department’s handout says review time depends on its workload, the project’s complexity and the questions that come up, that a complete application with plans showing code compliance is the best way to speed it up, and that state law requires review within 30 days. Files also wait on a missing earlier approval in Trumbull’s chain (wetlands before zoning, zoning before building), a commercial plan still out with the Fire Marshal, or a tax clearance held up by an e-check.

Trumbull inspections and closeout

Under the State Building Code the permit holder must tell the building official when work is ready. Trumbull takes inspection requests by phone at 203-452-5020 and asks callers not to leave them on voicemail; inspectors are in the office from 7:30 to 10 a.m. The required inspections are footings, with forms checked before the concrete is poured; foundations before backfill; mechanical fasteners; framing with the rough plumbing, heating and electrical before walls are closed or insulated (decks get a framing and flashing inspection); insulation before drywall; and a final before anyone moves in.

When the work is done, the owner or contractor picks up a request for certificate of occupancy form at the Building Department and gets each department that signed off on the permit to sign that its requirements were met; the building official then issues the certificate. The town code also requires an approved septic system or sewer connection before a certificate of occupancy is issued.

Connecticut building code

Trumbull’s code adopts the State Building Code as the town building code. The edition in force is the 2022 Connecticut State Building Code, based on the 2021 International Codes, for applications filed from October 1, 2022; the 2026 edition is delayed, and the filing date will fix 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

No. The Building Department does not accept cash.

Do I need a permit for a shed?

Not a building permit for a shed of 200 sq ft or less, but every shed needs Planning and Zoning approval and must meet the setbacks for accessory structures.

Why was my permit held up over taxes?

Town code section 5-6 withholds approval while taxes or sewer charges on the property are delinquent; pay them and get the Tax Collector’s clearance.

Is there a waiting period to demolish an old house?

For buildings of 500 sq ft or more built before 1940, yes: a 30-day review by the Demolition Review Committee and, if it finds possible historic significance, a further 90-day delay period.

Trumbull permit search and official resources

The department’s municipal search works street by street: the town website lists permit cards by street name, each card shows the permits taken out on that street by date, and you email the permit numbers you need to buildinginfo@trumbull-ct.gov for status and copies. The office holds permits from 1971 on and emails newer records (permits after December 2013 and mechanical permits from 2007). Monthly permit reports are posted on the website, and under a 2017 state law a one- or two-family permit with no certificate of occupancy is deemed closed nine years after it was issued. Trumbull’s FEMA flood maps date from June 18, 2010, and in a flood hazard zone even a foundation repair needs a zoning permit.
