Norwich, Connecticut Building Permit Guide

In the City of Norwich, the Building Department in Planning and Neighborhood Services issues building, electrical, plumbing, mechanical, roofing and demolition permits, and the City takes applications through its OpenGov portal. Under Ordinance No. 1870, in force since July 1, 2025, the building permit costs $40 for the first $1,000 of construction value and $20 for each further $1,000, plus the state education fee.

The department is on the first floor at 23 Union Street, open 8:30 a.m. to 4:30 p.m. on weekdays, with inspectors in the field from 9:30 a.m. to 3 p.m.; Christopher Burger is the Building Official. Norwich is a consolidated city and town of about 40,000 people (Census estimate for 2025), so one building office covers all of it, both the City Consolidation District and the Town Consolidation District.

What requires a building permit in Norwich?

The portal’s building permit page lists the common jobs, and it adds that no trade work can be done under a building permit: electrical, plumbing, mechanical, roofing and fire protection work each has its own permit type.

The City’s permit tutorial says a deck needs a building permit whatever its size, while the code exemption list that the City reprints in its 2023 handout excuses a detached deck of 200 sq ft or less, no more than 30 inches above grade, that needs no guards and does not serve the required exit door; the code list is the adopted rule.

What the city decides and what the state holds

Norwich sets the fee ordinance in chapter 4 of its code, the portal filing system, the inspection booking system and the demolition notice periods. The code, the list of exempt work and every trade license 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

Norwich building department: who handles permitting

The Building Department administers the State Building Code: it takes applications, reviews plans, inspects construction, issues certificates of occupancy and demolition permits, and coordinates projects with Norwich Public Utilities, which issues its own permits for water and sewer service lines. Zoning permits, the Commission on the City Plan, the Inland Wetlands, Watercourses and Conservation Commission and coastal site plan review sit in the same Planning and Neighborhood Services office. The Uncas Health District handles septic systems, and the Fire Marshal reviews the plans of permits that need its sign-off, though it does not inspect one- and two-family homes for life safety.

Permit types

Residential permits

For a house project the City asks for a specific description: an application that only says “build garage” or “fence” will not be approved. The tutorial explains how to print the lot from the City’s GIS at a scale of 40 and draw the site plan on it with setbacks and dimensions, and engineered plans are needed for larger work such as a new home. Handouts cover finished basements, pools, decks for one- and two-family homes and when architectural plans are required. Roofing has a quick form that needs photographs of the sheathing, ice barrier, seam tape, underlayment, drip edge, step flashing and finished roof, and an overlay must show that the existing roof does not have too many layers and is not waterlogged.

Commercial permits

Commercial fit-outs, changes of use and new commercial buildings file on the same building permit, with fire alarms, sprinklers and kitchen hoods on a separate fire protection systems permit. The Fire Marshal wants plans in full-size paper form and will not approve a final certificate of occupancy for a project whose plans it did not review before work began. A new or changed business first gets a zoning verification, and tents, construction trailers and events take a temporary installation permit.

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

What comes before the building permit

The zoning enforcement officer must issue a zoning permit before the building inspector can issue a building permit for new buildings, additions, pools, fences, sheds, garages, driveways and changes of use. Special permits, site plans, wetlands, subdivision, coastal area management and variance applications are still filed on paper, with the portal used to hold the documents. Any activity within 100 feet of a wetland or watercourse needs the wetlands agent’s review, and the zoning regulations were amended by Ordinance No. 1881 in January 2026. On a septic lot the Uncas Health District reviews additions, decks and pools under the Public Health Code’s B100a rule.

Norwich permit costs and fees

Fees are set in sections 4-3 and 4-5 of the Code of Ordinances, rewritten by Ordinance No. 1870 of April 21, 2025 and in force since July 1, 2025. The fee is first paid on the estimated cost; under section 4-6, when the finished work cost more than $500 the applicant files a declaration of the actual cost and pays the difference, and a lower actual cost is refunded.

Worked example. A $20,000 bathroom and kitchen renovation pays $40 for the first $1,000 and 19 × $20 ($380) for the rest, $420, plus $5.20 in state education fee: $425.20, before any plan review or certificate fees. Expedited handling of the same permit would add another $420.

The City’s Building Fees web page, which it calls a courtesy, still shows several older figures: a $35 minimum, $150 for an initial plan review, $250 for an annual maintenance permit, $950 for a mobile home and a $250 charge for work done without permits. It describes the $50 and $100 inspection charges as re-inspection fees. The ordinance figures are the adopted ones, and the page’s refund rules still apply: requests in writing within 30 days of approval, a $50 administrative charge, and no refund once a review or inspection has been done.

Trade permits and who may pull them

Each trade files its own permit in the portal. The electrical permit covers new circuits, solar with or without batteries, EV chargers, mini-split circuits, low-voltage systems and pool bonding; the mechanical permit covers boilers and furnaces (like-for-like replacements included), wood and pellet stoves, chimney liners, gas piping, heat pumps and vented fans; the plumbing permit covers water heaters, fixtures and gas piping, with pressure tests done with the appliances disconnected.

The Department of Consumer Protection issues the trade licenses and registers home improvement and new home construction contractors.

How to apply for a Norwich building permit

Review, corrections and what causes delay

The usual hold-ups are a vague project description, image files instead of PDFs, a missing owner’s authorization and a building permit filed before the zoning permit. Expedited review moves a file ahead of the queue but, as the ordinance says, depends on staff availability and does not guarantee approval. Section 4-8 bars a permit or certificate of occupancy while property taxes are delinquent, unless the Building Official finds a safety risk or the City Manager approves. Demolition of a building of 500 sq ft or more needs a newspaper notice at least 30 days before the permit (60 days for historic district or National Register buildings), mailed notice to abutters and a 2 by 3 foot sign posted for 30 days.

Inspections in Norwich

Request inspections through the portal, which the City prioritizes, or by phone on 860-823-3766 or 860-823-3739, giving the inspection type, address and permit number. In busy periods inspections may be booked 14 days or more ahead. Permits from the City’s older computer system are handled through the office staff.

The City’s required inspections handout lists footings (with all property corners located and marked so setbacks can be checked), foundation walls, framing and masonry, rough plumbing, electrical and mechanical with pressure tests, wallboard, and the final, for which house numbers, sidewalks and final grading must be done. Floodplain inspections, checked against the FEMA flood maps that took effect on August 1, 2023 (the City posts the panels on its maps page), and insulation, fire-rated construction and radon or vapor barrier inspections can be added. The Fire Marshal does not do residential life safety inspections of one- and two-family homes.
