The Town of Greenwich's Building Inspection Division, part of the Department of Public Works on the second floor of Town Hall at 101 Field Point Road, enforces the Connecticut State Building Code for a coastal town of around sixty-five thousand people at the south-western corner of the state, with the state line at its back. The public counter is open from eight in the morning to one in the afternoon, and the division's process starts before the application does: a group number and sign-off sheet are obtained in person, the sheet shows which town departments must approve the project, and the applicant collects those approvals — zoning, sewer, health and whichever others are ticked — before the building permit is filed with two sets of plans.
Zoning is the first tick on every sheet. Every zoning permit and some trade permits are reviewed for compliance with the Building Zone Regulations before the division will accept the application, the Zoning Enforcement Office sits inside the division for that reason, and both the zoning enforcement officer and the building official must sign every certificate of occupancy before it takes effect. A limited set of application types can be filed by email; the rest are filed in person, and inspections are scheduled through the City Squared system once a permit exists.
This guide covers the Town of Greenwich, including its villages of Old Greenwich, Riverside, Cos Cob and Byram. Stamford is a separate city, the state line lies to the west and south-west, and no county building department exists anywhere in Connecticut.
Get the group number before anything else. Nothing is filed in Greenwich until the Building Inspection Division has issued a group number and a sign-off sheet, and the sheet is the route map: each ticked department must approve by signature or by email before the application is accepted. Zoning review comes first, and the zoning enforcement officer co-signs the certificate of occupancy at the end.
What requires a building permit in Greenwich?
Connecticut has one building code and no town may amend it. The State Building Inspector and the Codes and Standards Committee adopt the Connecticut State Building Code jointly under section 29-252 of the General Statutes, with the approval of the Commissioner of Administrative Services, and section 29-253 makes it the building code of every town, city and borough in the state. The edition in force is the twenty twenty-two Connecticut State Building Code, which has governed every permit applied for since the first of October twenty twenty-two and is built on the twenty twenty-one international building, residential, existing building, mechanical, plumbing, energy and swimming pool codes with Connecticut amendments, together with the twenty twenty National Electrical Code. A twenty twenty-six edition built on the twenty twenty-four model codes was drafted to take effect in July twenty twenty-six, but the legislature's Regulation Review Committee declined to approve it that April and its effective date is delayed; the twenty twenty-two code governs until a new one is approved, and when the change comes it will turn on the date of the permit application. So Greenwich neither adopts nor amends the code — it enforces it through a building official licensed by the state — and the practical questions are the local process, the zoning and wetlands approvals that come before a building permit, and the group number and sign-off sheet the town requires before it will take a filing.
The code itself draws the permit line, and it draws it in the same place in every town. Section 29-263 requires a permit before any building or structure is constructed or altered, and the code's own exemptions — ordinary repairs, small detached accessory structures, fences and retaining walls below its stated sizes, finish work and the like — are the state's exemptions rather than a local list. A town cannot add exemptions or take them away. What it can do is set its own fees, run its own portal, and sequence its own zoning, wetlands and health sign-offs ahead of the building permit.
Typically permit required
- Interior renovations that alter walls, windows, load-bearing elements or any trade system, under the town's own guidance
- A group number and completed sign-off sheet before any building permit application is accepted
- Zoning review under the Building Zone Regulations before the division will take the file
- New buildings, additions and any structural work, under section 29-263 of the General Statutes
- Alterations, renovations and repairs beyond the code's ordinary-repair exemption, and any change of use or occupancy
- Decks, sheds and accessory structures above the code's exemption sizes, retaining walls and swimming pools
Often exempt
- Painting, tiling, cabinetry without moving utilities and certain minor repairs, on the town's work-exempt list
- Ordinary repairs that do not alter structure, egress, fire protection or building systems
- Ordinary repairs that do not alter structure, egress, fire protection or building systems
- One-storey detached accessory structures, fences and retaining walls below the code's stated exemption sizes
- Painting, papering, tiling, carpeting, cabinets, worktops and similar finish work
What the town decides and what the state holds
Every town appoints a building official under section 29-260, and that official must hold a licence from the State Building Inspector under section 29-262, kept current through state-run continuing education funded by the education fee charged on every permit. The town sets the fee schedule, chooses the portal, decides how plans are submitted and runs its own Board of Appeals under section 29-266 for disputes with the building official, whose decisions go on to the Codes and Standards Committee. What the town does not hold is the code: variations from it are granted by the State Building Inspector on an application routed through the local official, historic buildings can be exempted only under section 29-259, and state-owned buildings are permitted by the state itself under section 29-252a. There is no county layer either — Connecticut abolished county government in nineteen sixty, so nothing sits between the town and the state. Beyond that, the group number and sign-off sheet that precede every filing, the zoning review that comes first, the shoreline and the coastal review, and the state line that ends the town's jurisdiction.
Who handles permitting in Greenwich?
The Building Inspection Division of the Department of Public Works is the permitting authority inside the town, enforcing the Connecticut State Building Code through a state-licensed building official and issuing building and trade permits. The Zoning Enforcement Office inside the division reviews zoning compliance first and co-signs certificates of occupancy, the sewer, health, conservation and coastal reviews sign the sheet where ticked, the fire marshal reviews plans alongside the building official, and the Department of Consumer Protection registers and licenses contractors statewide.

Permit types
Residential permits
A Greenwich house project begins at the second-floor counter with the group number, carries the sign-off sheet to zoning, sewer or septic and health, and files two sets of plans once every ticked box is signed or confirmed by email; the trades follow on their own permits, some of them eligible for email filing. The Building Zone Regulations govern setbacks, coverage and floor area closely, and on the shore, the Mianus and Byram river valleys and the back-country wetlands the conservation and coastal reviews are ticks on the sheet too.
How Connecticut contractor credentials work
Connecticut has no general contractor licence. The Department of Consumer Protection registers home improvement contractors under the Home Improvement Act for work on existing dwellings and new home construction contractors under their own chapter for building new ones, each paying into a guaranty fund that reimburses homeowners when a registered contractor fails to perform, and each obliged to put the registration number on a written contract that carries the owner's cancellation rights. The trades are licensed rather than registered: electrical, plumbing and piping, heating and cooling, sheet metal, fire protection and elevator work each require an occupational licence issued by the department after examination, in contractor and journeyperson classes. Above the threshold limits of section 29-276b a major contractor registration applies as well, and the building official must be satisfied that the architect, engineer, general contractor and major subcontractors on such a project all hold their credentials. In Greenwich the building official checks the registration or licence at permit issue, and a contractor applying as the owner's agent under section 29-263 files with the owner's written authorisation.
Commercial permits
Commercial work in Greenwich — the Greenwich Avenue and railway-station districts, the office campuses along the parkway and the hospital — files with sealed drawings after the same sign-off sequence, the fire marshal's review and, where the Planning and Zoning Commission's approval is required, the commission's decision in hand. The town's height limits keep most buildings below the threshold limits, but the review and the major contractor registration apply where they are crossed.
What comes before the building permit
In Connecticut the building permit is rarely the first approval and almost never the only one. Zoning is a separate town function under chapter 124 of the General Statutes, and most towns require a zoning permit or a sign-off from the zoning enforcement officer before the building official will accept an application; the inland wetlands agency must act first on any work near a wetland or watercourse; coastal towns run coastal site plan review for work inside the coastal boundary; the local fire marshal reviews plans for Fire Safety Code compliance alongside the building official under section 29-263; and a lot on a septic system needs the health department before the town will take the file. None of these is a building code question, and none can be waived by the building official. In Greenwich the Sound shoreline and the tidal river mouths bring coastal site plan review and flood-zone elevation rules, the back-country wetlands and watercourses bring the conservation review, and the state line to the west and south-west ends the town's jurisdiction where the road signs change.
Greenwich permit costs and fees
Greenwich charges building and trade permit fees on the declared construction value under its published fee schedule, with the state's education fee on every building permit and separate fees for the zoning permit and the other sign-offs on the sheet.
| Item | Fee or rule |
|---|---|
| Building permit | Valuation-based on the declared construction value, per the town's fee schedule |
| State education fee | Twenty-six cents per thousand dollars of declared value, remitted to the state |
| Zoning permit | Separate fee, reviewed before the building permit is accepted |
| Trade permits | Separate electrical, plumbing and heating and cooling fees; paid at the counter |
| Sewer, health and conservation | Their own fees where ticked on the sign-off sheet |
| Records | Surveys, permit reports, plans and certificate copies by email request and appointment |
The counter closes at one, and fees are paid at it. Greenwich's public counter runs from eight to one. Trade permits and permit fees are handled at the counter rather than by post, so a fee arriving at two in the afternoon waits for the next morning. Building the counter's hours into the filing plan is not optional.
Trade permits and who may pull them
Trade work is permitted separately in every Connecticut town and carried out by tradespeople holding the occupational licence the Department of Consumer Protection issues for that trade. A home improvement registration does not cover licensed trade work, and a licensed tradesperson working within the licence needs no registration.
Permit required
- Any trade permit that needs a zoning sign-off — reviewed for zoning compliance before the division accepts it
- Electrical — separate permit, by a licensed electrical contractor of the appropriate class
- Plumbing and piping — separate permit, by a licensed plumbing contractor
- Heating, cooling and sheet metal — separate permit under the mechanical code, by the licensed contractor for that class
- Fire protection sprinklers and alarms — separate permit, with the local fire marshal's review
Typically exempt
- Like-for-like replacement of fixtures and appliances that the code's own exemptions leave outside the permit
- Minor low-voltage and portable equipment work within the code's electrical exemptions
How to apply for a Greenwich building permit
The building official will not take an application the zoning enforcement officer has not cleared, and wetlands, coastal and septic approvals run through their own boards.
The twenty twenty-two Connecticut State Building Code governs until the delayed twenty twenty-six edition takes effect; the application date fixes which one applies.
Home improvement or new home construction registration from the Department of Consumer Protection, and the occupational licence for each trade.
Section 29-263 requires the owner's application or written authorisation, plans reviewed by the building official and the fire marshal, and the state education fee on the declared value.
The building official must act on an application within thirty days of receipt; corrections restart the clock in practice, and threshold-limit projects add the independent structural review.
Footing to final, trades on their own permits, then the certificate of occupancy under section 29-265.
Review, corrections and what actually causes delay
The Building Inspection Division reviews for the State Building Code with the fire marshal alongside, but only once the sign-off sheet is complete; zoning review comes before that. What delays a Greenwich project is an application presented without a group number, a sheet with a department unsigned, a set filed by email that the division only takes in person, and an arrival after one o'clock.
Inspections in Greenwich
Inspections follow the code's sequence in every town — footing, foundation, framing, rough electrical, plumbing and mechanical, insulation and final — requested from the building official by permit number, with the trades inspected on their own permits. Work that passes final receives a certificate of occupancy under section 29-265, without which a new or altered building may not be occupied; on a project above the threshold limits the architect and engineer of record and the general contractor also sign a statement of professional opinion that the finished work substantially matches the approved plans. Greenwich inspections are scheduled through City Squared against the permit number, with building, electrical, plumbing and heating and cooling inspectors at each critical stage; the certificate of occupancy takes effect only once both the building official and the zoning enforcement officer have signed it.

Frequently asked questions
What is a group number?
The number the Building Inspection Division issues in person at the start of an application. It organises the file and tracks the departmental sign-offs the sheet requires.
Does zoning review come before the building permit?
Yes. Every zoning permit and some trade permits are reviewed for compliance with the Building Zone Regulations before the division will accept the application.
Who signs the certificate of occupancy?
Both the building official and the zoning enforcement officer. A certificate is not effective until both have signed.
Which code applies?
The twenty twenty-two Connecticut State Building Code, uniform statewide. The twenty twenty-six edition is delayed and does not yet apply.
Can I file by email?
Only for a limited set of application types. The rest are filed in person with two sets of plans, and the counter is open from eight to one.
Is there a county building department?
No. Connecticut abolished county government in nineteen sixty. The town is the only permitting authority inside its limits, and the state line ends it to the west.
