Fundamentals of Virginia Mechanics Liens & Statutory Deadlines

Key Takeaways

  • Title 43 of the Code of Virginia (Va. Code § 43-1 et seq.) governs all mechanics' liens, establishing statutory encumbrances on real property to secure payment for labor performed or materials furnished.
  • Under Va. Code § 43-4, a Memorandum of Lien must be filed no later than 90 days from the last day of the month in which labor was last performed or materials furnished, or within 90 days from project completion/termination, whichever occurs first.
  • Virginia enforces a strict 150-day lookback rule (Va. Code § 43-4): a mechanics' lien cannot include sums for labor or materials furnished more than 150 days prior to the last day labor was performed or material furnished on the job.
  • Failure to meet either the 90-day filing deadline or the 150-day lookback rule renders the entire mechanics' lien invalid and unenforceable in Virginia courts.

Fundamentals of Virginia Mechanics Liens & Statutory Deadlines

Statutory Basis & Purpose of Virginia Mechanics' Liens

Under Virginia law, a mechanics' lien is a powerful statutory remedy created by Title 43 of the Code of Virginia (Va. Code § 43-1 et seq.). It provides contractors, subcontractors, material suppliers, and design professionals with a direct security interest in the real property they improve. Because real estate cannot easily be liquidated or hidden, a properly recorded mechanics' lien clouds the property owner's title, making it difficult or impossible to sell, refinance, or convey the property until the underlying construction debt is satisfied.

The core principle behind Virginia's mechanics' lien statutes is preventing unjust enrichment. When a contractor performs labor or furnishes materials that increase the value of real property, equity dictates that the property itself should serve as security for the payment earned.

Entitled Claimants Under Title 43

Under Va. Code § 43-3, the following entities are entitled to record a mechanics' lien for work or materials furnished for the construction, removal, repair, or improvement of any building or structure:

  • General Contractors (Tier 1): Entities contracting directly with the property owner.
  • Subcontractors (Tier 2): Entities contracting directly with a general contractor.
  • Sub-subcontractors & Material Suppliers (Tier 3): Entities contracting with subcontractors or supplying raw materials/equipment used in the structure.
  • Design Professionals: Registered architects, professional engineers, and land surveyors who perform professional services directly connected to the physical improvement of the land.

The 90-Day Filing Rule (Va. Code § 43-4)

Virginia maintains one of the strictest mechanics' lien enforcement regimes in the United States. Compliance with filing deadlines is mandatory and strictly enforced by Virginia courts.

Under Va. Code § 43-4, any claimant seeking to enforce a mechanics' lien must record a Memorandum of Mechanics' Lien in the Circuit Court clerk's office where the land is situated no later than:

  1. 90 days from the last day of the month in which the claimant last performed labor or furnished material; OR
  2. 90 days from the time the building, structure, or project is completed (or work thereon is otherwise terminated), whichever date occurs first.

Critical Distinction — End-of-Month Calculation: Unlike many states that calculate deadlines strictly from the last calendar day work was performed, Virginia measures the primary 90-day window from the last day of the month in which labor or materials were furnished. For example, if a subcontractor performs their final work on June 10th, the 90-day statutory clock does not begin running until June 30th. The claimant has 90 days from June 30th (until September 28th) to record the memorandum, provided the overall project is not completed earlier.

ScenarioLast Work DateEnd of Month Date90-Day Filing Deadline
Mid-Month WorkMarch 12March 31June 29
End-of-Month WorkMarch 31March 31June 29
Project Completed EarlyApril 15 (Project Done)April 30July 14 (90 Days from Completion)

If the overall building or structure is completed before the end of the 90-day window, the 90-day cutoff from project completion overrides the end-of-month calculation.


The 150-Day Lookback Rule (Va. Code § 43-4)

In addition to the 90-day filing deadline, Virginia imposes a unique limitation known as the 150-day lookback rule. This statutory constraint dictates which historical invoices can be included in the total lien amount.

Va. Code § 43-4 provides that:

"No memorandum of lien filed shall include labor or materials furnished more than 150 days prior to the last day on which labor was performed or material furnished preceding the filing of such memorandum."

How the 150-Day Lookback Operates

The 150-day rule establishes a rolling 150-day window measured backward from the claimant's last day of work. If a project lasts 10 months and the contractor is unpaid from month 1 through month 10, the contractor cannot file a single mechanics' lien covering the entire 10-month balance. Any labor or materials furnished earlier than 150 days prior to the last day of work must be excluded from the mechanics' lien claim.

[--- Excluded Unpaid Invoices (>150 Days Old) ---] | <====== 150-Day Lookback Window ======> | [Last Work Date] ---> 90-Day Filing Window
                                                   ^ (Only Work in this Window Can Be Liened)

Statutory Exception for Retainage

To protect contractors on long-term projects where contractual retainage (typically 5% to 10%) is withheld until final project completion, Va. Code § 43-4 provides a specific exception:

  • Retainage amounts exceeding the 150-day window may be included in the Memorandum of Lien, provided the retainage was legitimately withheld pursuant to the terms of a written contract and does not exceed 10% of the contract price.

Tier Structure & Defense of Payment (Va. Code § 43-7)

Virginia mechanics' lien rights depend directly on the claimant's contractual position within the project hierarchy.

Claimant TierContractual PrivityLien Rights & Defense of Payment
General Contractor (Tier 1)Direct contract with Property OwnerCan lien full contract balance owed by owner.
Subcontractor (Tier 2)Contract with General ContractorSubject to Defense of Payment; limited to amount owed by Owner to General Contractor at/after notice.
Sub-subcontractor (Tier 3)Contract with SubcontractorLimited by amount owed to Subcontractor AND amount owed to General Contractor.

The Defense of Payment Rule

Under Va. Code § 43-7, a subcontractor's lien rights are derivative. If the property owner has paid the general contractor in full in good faith before receiving notice of the subcontractor's lien, the owner's property is protected by the Defense of Payment. The subcontractor cannot force the owner to pay twice for the same work. Consequently, lower-tier claimants must monitor payments closely and act promptly.


Strictly Enforced Court Standards

Virginia courts treat mechanics' liens as statutory creations in derogation of common law. As established in landmark cases such as Page v. Clements, strict compliance with every statutory requirement is required:

  • Inclusion of unallowable amounts outside the 150-day window can render the entire lien unenforceable.
  • Miscalculating the 90-day filing deadline by even a single day results in complete forfeiture of lien rights.
  • While a defective mechanics' lien forfeits real estate security, the contractor retains common law claims for breach of contract or quantum meruit against the party with whom they contracted.
