    Connecticut Mechanics Lien Law: Deadlines, Notices & Filing Guide

    Connecticut mechanics lien practice is governed by Conn. Gen. Stat. § 49-34 for private work and §§ 49-41a and 49-42 for public projects. The 90-day recording deadline and its companion sub-tier notice both run from last furnishing, so early tracking matters.

    Connecticut mechanics lien deadlines at a glance

    Preliminary / pre-lien notice

    Connecticut does not require a separate preliminary notice on private projects. However, sub-tier claimants must serve a Notice of Intent to Claim a Mechanics Lien within the same 90-day window that governs recording, so that notice functions as a practical precondition for those claimants.

    Lien recording deadline

    A Connecticut mechanics lien certificate must be recorded with the town clerk within 90 days after the claimant last furnished labor or materials, under Conn. Gen. Stat. § 49-34. A copy of the certificate must also be served on the owner within 30 days of recording.

    Suit to foreclose

    An action to foreclose the lien must be commenced within one year after the lien is recorded.

    Public-project bond claim

    On Connecticut public projects, a claimant must serve written notice of claim on the payment bond within 180 days of last furnishing labor or materials. For amounts attributable to retainage specifically, that notice window extends to 210 days.

    Connecticut lien rights are available to general contractors, subcontractors, sub-subcontractors, material suppliers, and design professionals where the statute permits, provided they furnished labor, materials, or services to the improvement.

    Overview of Connecticut lien practice

    Connecticut's 90-day recording window is short by national standards, and the state layers an additional requirement on top of it for sub-tier claimants, who must serve a Notice of Intent to Claim a Mechanics Lien within that same 90-day period to protect their position. Once the certificate is recorded with the town clerk, a copy must reach the owner within 30 days, a step that is easy to overlook amid the rush to meet the recording deadline itself. Foreclosure must follow within one year of recording, giving Connecticut claimants somewhat more breathing room than some other states allow for that stage. Public projects run on separate bond-claim timelines, with a standard 180-day notice window that stretches to 210 days for retainage-related claims. As elsewhere, confirming the correct town clerk's office, the accurate owner of record, and the fact that federal property cannot be liened remain baseline diligence steps for any Connecticut claimant.
