Connecticut Mechanics Lien Law: Notices, Deadlines, Lien Rights, and Contractor Registration

A mechanics lien is a legal claim against improved real property that helps secure payment for materials furnished or services rendered to a construction project. In Connecticut, it is a useful payment-security tool because it can give contractors, subcontractors, and suppliers a recorded interest in the property improved by their work.

1. Connecticut Lien Notices: Original Contractors and Lower-Tier Claimants Are Treated Differently

The key point is that Connecticut does not require the same notice from every claimant.

Original contractors generally do not need a notice of intent

An original contractor, meaning the contractor who contracts directly with the owner, generally does not need to give the separate notice of intent required of lower-tier claimants. The original contractor must still timely record a proper certificate of lien and serve the owner with a true and attested copy of the certificate.

Subcontractors and material suppliers usually need notice of intent

Under Conn. Gen. Stat. § 49-35, a person other than the original contractor generally must give written notice to the owner and to the original contractor that the claimant has furnished or commenced to furnish materials, or rendered or commenced to render services, and intends to claim a lien. The notice must be given after commencing, and not later than 90 days after ceasing, to furnish materials or render services.

There is an important exception. A subcontractor whose contract with the original contractor is in writing and has been assented to in writing by the other party to the original contract is not subject to the same notice-of-intent requirement. In practice, lower-tier claimants should not assume this exception applies unless the required written contract and written assent are clear and available.

The certificate of lien must also be served on the owner

Under Conn. Gen. Stat. § 49-34, a mechanics lien is not valid unless the claimant records the certificate within 90 days after ceasing to furnish services or materials and serves a true and attested copy of the certificate on the owner not later than 30 days after lodging the certificate for record. This service requirement is separate from any notice of intent required under § 49-35.

2. Connecticut Mechanics Lien Timing Requirements

The key point is that Connecticut's main recording deadline is 90 days after the claimant stops furnishing services or materials, followed by a 30 day service deadline and a one year foreclosure deadline.

A certificate of lien is lodged with the town clerk in the town where the building, lot, or plot of land is located. The certificate must describe the premises, state the amount claimed, identify the person against whom the lien is filed, state the date when the claimant began furnishing services or materials, state that the amount claimed is justly due as nearly as can be ascertained, and be subscribed and sworn to by the claimant.

Under Conn. Gen. Stat. § 49-39, a mechanics lien does not continue in force for more than one year after it has been perfected unless the claimant commences an action to foreclose it and records a notice of lis pendens on the land records within that one year period. If the claimant does not do both, the lien is invalid and discharged as a matter of law.

3. Connecticut Lien Amounts: The Lien Is Limited by the Statute and the Contract Chain

The key point is that Connecticut lien rights depend on the amount justly due and, for subcontractors, on the available lienable fund.

Under Conn. Gen. Stat. § 49-33, a person with a claim of more than 10 dollars for materials furnished or services rendered in covered construction, repair, improvement, site development, or subdivision work may have lien rights if the work or materials were furnished by agreement with, or consent of, the owner or a person with authority from the owner.

For subcontractors, the lien generally cannot attach to the property for more than the amount the owner agreed to pay to the person through whom the subcontractor claims. Connecticut law also accounts for the cost to complete the original contract, damages from default, and bona fide payments made by the owner before receiving notice of the lien. This is why the subcontractor's lien may be limited even if the subcontractor is fully unpaid.

Connecticut therefore does not use a simple "full price lien" and "unpaid balance lien" label in the same way some states do. The practical questions are:

• Is the claimant within the statutory class?
• Was the claim for materials furnished or services rendered to the specific property?
• Did the owner consent, or did a person with authority from the owner procure the work or materials?
• Was the certificate recorded within 90 days after the claimant ceased furnishing?
• Was any required notice of intent served?
• Is there a lienable fund available for a subcontractor or supplier claim?

The lien amount should be tied to the property and the amount justly due, after credits. It should not include unrelated invoices, non-project debt, or amounts that cannot be supported by contracts, change orders, invoices, delivery records, and payment history.

4. Who Can Claim a Connecticut Mechanics Lien, and Who Cannot

The key point is that Connecticut lien rights are broad enough to cover many project participants, but they are not automatic.

Connecticut lien rights may cover persons furnishing materials or rendering services for the construction, raising, removal, or repairs of a building or appurtenances, the improvement of a lot, or site development or subdivision of a plot of land. Connecticut case law recognizes lien rights for material suppliers and certain design or professional services when the statutory requirements are met.

Important limits apply:

• Suppliers to suppliers should not assume lien rights. A remote supplier may have difficulty showing the statutory agreement, consent, and project connection required for lien rights.
• Materials must be furnished and used for the particular improvement. Connecticut authorities have long required a project connection for material claims.
• Public buildings generally are not subject to mechanics liens. On public work, payment bonds and public project remedies should be evaluated instead.
• Owner consent matters. Mere knowledge that work is being done may not be enough in some circumstances. The claimant should be able to show agreement, consent, or authority under the statute.
• Leasehold work may create leasehold lien issues. Section 49-33 includes provisions addressing claims based on agreement with or consent of a lessee, but the property interest subject to lien may differ from an owner-fee lien.

The claimant should identify the contracting chain, owner consent, property interest, last furnishing date, and available lienable fund before recording.

5. Contractor Registration Can Affect Contract and Lien Enforcement

The key point is that Connecticut registration rules can affect payment rights, especially on residential home improvement work.

Connecticut regulates home improvement contractors under the Home Improvement Act, Conn. Gen. Stat. § 20-418 et seq. That law generally requires registration and imposes strict written-contract requirements for covered home improvement work. Connecticut courts have treated noncompliance with the Home Improvement Act as a serious problem for contract enforcement. In All American Pools, Inc. v. Lato, 20 Conn. App. 625, 569 A.2d 562 (Conn. App. 1990), the court discussed Home Improvement Act issues in a mechanics lien foreclosure dispute involving pool repair work.

Connecticut separately regulates new home construction contractors under the New Home Construction Contractors Act, Conn. Gen. Stat. § 20-417a et seq. The consequences are different. In D'Angelo Development & Construction Co. v. Cordovano, 278 Conn. 237, 897 A.2d 81 (Conn. 2006), the Connecticut Supreme Court held that a new home construction contract that failed to comply with registration, disclosure, and contract-language provisions of that Act was not rendered unenforceable because the Act did not include contract invalidation as a penalty. The court also declined to invalidate the contractor's mechanics lien on that basis.

For lien claimants, the practical rule is to check the project category before work starts. A contractor should confirm whether the job is home improvement, new home construction, commercial work, trade-regulated work, or another category. The contracting entity, registration status, written contract, notices, and lien documents should all be consistent. Registration defects can create contract defenses, consumer protection claims, administrative penalties, and challenges to lien enforcement.

6. Suit to Enforce the Lien and the Lis Pendens Requirement

The key point is that recording and serving the lien certificate are not enough. The lien must be foreclosed on time.

Under Conn. Gen. Stat. § 49-39, the claimant must commence an action to foreclose the lien by complaint, cross-complaint, or counterclaim, and must record a notice of lis pendens on the land records of the town where the lien is recorded. Both steps must occur within one year from the date the lien was recorded, unless the statute provides a later deadline because of a lien discharge application and appeal process.

If the claimant misses the one year foreclosure and lis pendens deadline, the lien is invalid and discharged as a matter of law. Filing a lawsuit without recording the lis pendens can create risk. Recording a lis pendens without commencing the proper foreclosure action is also not enough.

Connecticut also has procedures for an owner to apply to discharge or reduce a mechanics lien. A claimant should be prepared to show probable cause for the lien, including the contract or consent basis, the amount due, the services or materials furnished, timely recording, required notices, and proper service.

Practical Takeaways for Connecticut Contractors, Subcontractors, and Suppliers

The key point is that Connecticut lien rights depend on proper notice, timely recording, owner service, and a timely foreclosure action.

• Original contractors generally do not need the separate lower-tier notice of intent.
• Many subcontractors and suppliers must give written notice of intent to the owner and original contractor after commencing and not later than 90 days after ceasing work or furnishing materials.
• The certificate of lien must be recorded within 90 days after the claimant ceases furnishing services or materials.
• A true and attested copy of the certificate must be served on the owner within 30 days after lodging the certificate.
• The foreclosure action and lis pendens must be filed within one year after the lien is recorded.
• Subcontractor liens are limited by the lienable fund and the owner's contract obligations and bona fide payments.
• Materials and services must be tied to the specific property and statutory improvement.
• Public buildings generally cannot be liened. Check bond remedies instead.
• Home improvement and new home construction registration rules should be checked before contracting and before filing a lien.
• Keep contracts, change orders, invoices, delivery records, payment records, and service proof organized by project.
