Sharing Helpful Information: Clarifying Connecticut’s 9-Year Permit Closure Rule
There has been some confusion regarding the closing out of building permits after nine years, pursuant to C.G.S. §29-265(c). This section refers specifically to permits for which “certificates of occupancy” (“COs”) have not been issued. However, not all permits require a CO. Some permits are closed out by Certificates of Approval (“COAs”) which are not mentioned in the statute.
According to §R110.10 of the Connecticut State Building Code, COAs are issued “for all completed work that requires a building permit but does not require a certificate of occupancy. Such work shall include, but not be limited to: fences greater than 7 feet (2134 mm) in height; retaining walls greater than 3 feet (914 mm) in height; decks; garages; swimming pools; basements and attics converted to habitable space; electrical, plumbing and mechanical repairs or alterations.”
The fact that §29-265(c) does not expressly include permits for which a COA has not been issued has led some municipalities to consider such permits excluded from the statute, and therefore not closed out after nine years. In response to this position, On May 27, 2026, the Connecticut State Building Inspector, Omarys C. Vasquez provided guidance to all Connecticut building officials. Below are the key points of her communication:
• While the statute explicitly names "Certificates of Occupancy," the Certificate of Approval is a Connecticut-specific amendment. Because COAs do not exist in the model codes, they were not explicitly spelled out in the broad statutory language.
• For all intents and purposes, a Certificate of Approval falls squarely under the Certificate of Occupancy master section (R110 in the IRC). In other words, a Certificate of Approval is a sub-type of a Certificate of Occupancy.
• The original intent of the statute at the time of enactment was to close out any and all outstanding permits for one- and two-family dwellings after nine years where a final certificate had not been issued—regardless of whether that final sign-off was a CO or a COA.
• Based on this historical intent and code structure, the 9-year statute does apply to Certificates of Approval.
