Connecticut Building Permit Guides

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 and decide how applications are filed, within the state rule that it must accept them in person, by post or by email. The zoning, wetlands and health approvals that come before the building permit are set by state law, and each town runs them through its own officials.

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, decides how applications are filed (state law lets you file in person, by post or by email) 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; for a historic structure on the State Register of Historic Places, the State Building Inspector and the Codes and Standards Committee can set aside or modify individual standards under section 29-259, and work by state agencies needs no town building permit — under section 29-252a the State Building Inspector permits the larger state projects and the agency certifies the rest. There is no county layer either — Connecticut abolished county government in 1960, so nothing sits between the town and the state.

What comes before the building permit

In Connecticut the building permit is often not the first approval you need. Zoning is a separate town function under chapter 124 of the General Statutes, and state law says no building permit can be issued for work that is subject to zoning until the zoning enforcement officer certifies in writing that it complies (section 8-3). Work in or near a wetland or watercourse that is likely to affect it needs a permit from the town’s inland wetlands agency, and zoning cannot decide a site plan for that work until the agency has reported. Coastal towns run coastal site plan review, through zoning, for larger projects inside the coastal boundary; many towns exempt minor residential work. The local fire marshal reviews plans where the Fire Safety Code applies, and on a lot with a septic system the local health department must approve additions, conversions, changes of use, garages, sheds and pools before the building permit is issued. None of these is a building code question, and none can be waived by the building official.

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 pays into a state guaranty fund, which can pay homeowners who win a court judgment or arbitration award against a registered contractor and cannot collect it. Each must put its registration number on a written, signed contract, and a home improvement contract must also set out the owner’s right to cancel. 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. Larger contractors may also need major contractor registration (section 20-341gg), and on projects above the threshold limits of section 29-276b the building official must be satisfied that the architect, engineer, general contractor and major subcontractors all hold their credentials.

Trade work needs a permit in every Connecticut town, and many towns issue it as a separate trade permit; it must be done by a tradesperson holding the Department of Consumer Protection licence for that trade. A home improvement registration does not cover licensed trade work, and a licensed tradesperson working within the licence needs no registration.
