Connecticut · Construction-defect rights
Here is what you have, and here is how to keep it.
Connecticut bars suits against an architect, professional engineer or land surveyor more than seven years after substantial completion (eight if the injury first appears in the seventh year). Crucially, this repose does NOT cover general contractors/builders — a claim against your builder runs under the three-year general tort statute instead.
What you have
If the builder or developer still controls the property, the deadline isn’t theirs to raise.
The exception most homeowners would never think to ask about: repose not assertable by a person in actual possession or control when the deficiency proximately causes injury/death (Conn. Gen. Stat. § 52-584a(d)) It matters most where a builder still controls part of a project — a phased subdivision, an unfinished condo association.
Your window depends on whom you are suing. Against an architect, engineer or land surveyor you have seven years from substantial completion (Conn. Gen. Stat. § 52-584a), and a party still controlling the property cannot raise it. Against a general contractor or builder there is NO seven-year repose — the three-year general tort statute (§ 52-577) runs from the act, so acting quickly matters far more.
The deadline
7 years to bring a construction-defect claim
Conn. Gen. Stat. § 52-584a(a)
SCOPE — READ FIRST: § 52-584a covers ONLY architects, professional engineers and land surveyors. A homeowner suing a GENERAL CONTRACTOR / BUILDER is NOT under this repose — that claim is governed by Connecticut's general tort statute § 52-577 (three years from the act or omission, an occurrence-based bar). So the "7 years" applies to design professionals; against a builder the practical deadline is much shorter. For design professionals: 7 years from substantial completion (§ 52-584a(a)), extended to at most 8 years if the injury first appears in the seventh year (§ 52-584a(b)). No fraud exception in the statute; a person in possession/control cannot raise it (§ 52-584a(d)).
“No action or arbitration, whether in contract, in tort, or otherwise, (1) to recover damages … shall be brought against any architect, professional engineer or land surveyor performing or furnishing the design, planning, supervision, observation of construction or construction of, or land surveying in connection with, such improvement more than seven years after substantial completion of such improvement.”
Before you sue: We have not yet confirmed whether Connecticut requires written notice to the builder before a lawsuit. Some states do, and skipping it can get a case stayed or dismissed. Ask a Connecticut attorney before filing.
What to do now
Write it down the day you notice it. Photograph it with something for scale. Note the date, the room, and what you saw. If it gets worse, photograph it again - a sequence is far stronger than one picture. Keep every message with the builder. You are not starting a fight; you are keeping the option open. Some states require written notice to the builder before you can sue. We have not confirmed whether Connecticut does, so check with a licensed attorney before filing. A record made at the time is what most people are missing later.
The same defect, a different answer next door
The construction-defect deadline is a state-by-state accident of geography. The identical crack in the identical house can be dead in one state and live in another.
