South Carolina Construction Lien Guide

⭐ South Carolina Lien Deadlines (Critical)

South Carolina lien law is strict. Missing a required notice or deadline can permanently destroy lien rights.

Deadline #1 — Send Notice of Furnishing (Subs & Suppliers Only)

Before a subcontractor or supplier can file a mechanics lien, a Notice of Furnishingmust be served.

Deadline:Within 30 days of first furnishing labor or materials

Failure to timely serve this notice completely bars lien rights for lower-tier claimants.

Deadline #2 — File the South Carolina Mechanics Lien

In South Carolina, a mechanics lien must be filed within ninety (90) days after the claimant last furnished labor, materials, equipment, or services to the project. This deadline is strictly enforced and applies to all lien claimants, including general contractors, subcontractors, and suppliers.

The “last furnishing” date is the date you last performed meaningful work or supplied materials that were part of the original contract or an approved change. Minor touch-ups, warranty work, or corrective work performed after substantial completion generally do not extend the lien deadline.

If the lien is not filed within this 90-day window, the right to claim a mechanics lien is permanently lost, regardless of the amount owed or the reason for nonpayment. South Carolina courts do not allow extensions or equitable exceptions for late filings.

Deadline #3 — Enforce the South Carolina Mechanics Lien

Filing a mechanics lien in South Carolina does not by itself secure payment. To preserve the lien and convert it into enforceable leverage, the claimant must initiate a lawsuit to enforce (foreclose) the lien within the statutory timeframe.

In South Carolina, enforcement must occur: Within six (6) months after the mechanics lien is filed.

Enforcement means filing a civil action in the appropriate court seeking to foreclose the lien against the property and obtain a judgment. Simply recording the lien, sending demand letters, or continuing settlement discussions does not stop or extend this deadline.

If a foreclosure action is not filed within the six-month window, the mechanics lien automatically expires by operation of law, even if the lien was validly filed and the debt remains unpaid. Once expired, the lien cannot be revived or refiled, and the claimant loses all lien-based leverage against the property.
