North Carolina: Mechanic's Lien Deadlines & Notice Requirements

The short answer

North Carolina runs its mechanic's lien system on a single trigger date —
the claimant's own last day of furnishing labor or materials — rather than
an owner-controlled completion notice. A contractor with a direct contract
with the owner has 120 days from that date to file a claim of lien on real
property, and 180 days from the same date to sue to enforce it. Subcontractors
don't get a direct real-property lien this way; instead they get a "lien upon
funds" against whatever the owner or a higher-tier contractor still owes,
which they can reach by simply serving written notice on whoever holds the
money. On larger projects, every claimant should also send a short notice to
the owner's lien agent within 15 days of first showing up on the job, or risk
losing priority if the owner sells or refinances before the lien is perfected.

Requirements one by one

Governing law

North Carolina's mechanic's lien law is General Statutes Chapter 44A, Article
2 ("Statutory Liens on Real Property"), split into Part 1 (liens claimed
against the owner directly) and Part 2 (liens on funds for subcontractors
dealing with someone other than the owner). It is an older, state-specific
statute, not built on a uniform act, and has been amended repeatedly —
including a 2025 session-law update to the lien-agent notice rules.

Who can claim

G.S. § 44A-8 gives a right to file a "claim of lien on real property" to
anyone who furnishes labor, professional design or surveying services,
materials, or rental equipment "pursuant to a contract, either express or
implied, with the owner." That direct-contract requirement is the key
dividing line: a subcontractor who never contracted with the owner instead
gets a "lien upon funds" under § 44A-18, secured against money owed to
whoever they did contract with. A subcontractor can still reach the real
property itself, but only by subrogation to the contractor's own lien rights
under § 44A-23, and only "to the extent of its claim."

Preliminary notice

North Carolina doesn't require any notice before you can claim a lien at
all. But for projects where the owner must designate a "lien agent" — a
title company or agency the owner names, required once a project's cost
reaches the statutory threshold — § 44A-11.2(l) lets a claimant preserve
full priority for its eventual lien only if the lien agent "received a
Notice to Lien Agent from the potential lien claimant no later than 15 days
after the first furnishing of labor or materials." Missing that window
doesn't destroy the underlying lien right; it just leaves the lien
subordinate to a mortgage or deed of trust, or a sale to a good-faith buyer,
recorded before the claimant otherwise perfects its lien.

Deadline to file the lien

Every claimant, contractor or subrogated subcontractor alike, files on the
same clock. G.S. § 44A-12(b) sets the deadline "not later than 120 days
after the last furnishing of labor or materials at the site of the
improvement by the person claiming the lien." There's no separate, shorter
window for subcontractors the way some states run it — the 120 days is
uniform once a claimant is filing a claim of lien on real property at all.

Notice of completion effect

North Carolina has nothing resembling a Notice of Completion or Notice of
Cessation that shortens a claimant's deadline. Both the 120-day filing
deadline and the 180-day suit deadline run from the claimant's own last date
of furnishing labor or materials, a date the claimant controls and records
on the lien form itself — not from any act the owner takes to close out the
project.

Serving the lien on the owner

Filing alone doesn't perfect a North Carolina lien. G.S. § 44A-11(a) requires
both "service of a copy of the claim of lien on real property upon the
record owner" and "filing of the claim of lien on real property under
G.S. 44A-12" before the lien is perfected. The statute spells out several
accepted, no-signature-required delivery methods (personal delivery or
deposit with the postal service or an authorized carrier), so a claimant
doesn't need to prove the owner actually received it, just that it was sent
the right way to an address the statute treats as good.

Deadline to sue to foreclose

The suit deadline tracks the same trigger date as the filing deadline,
just with a longer fuse. G.S. § 44A-13(a) bars any enforcement action
commenced "later than 180 days after the last furnishing of labor or
materials at the site of the improvement." There's no owner mechanism in
this statute to force an earlier suit or shorten that window.

Homestead/residential extras

The one residential carve-out in this chapter runs through the lien-agent
system, not the core filing or suit deadlines. G.S. § 44A-11.1(a) excuses an
owner from designating a lien agent at all "for improvements to an existing
single-family residential dwelling unit ... that is occupied by the owner as
a residence," or for an incidental accessory structure. On those projects,
the 15-day priority-notice mechanism simply doesn't apply, since there's no
lien agent to notify.

What trips people up

Because North Carolina's clock runs entirely off the claimant's own last
date of furnishing labor or materials, there's no owner filing to watch for
the way there is in states with a notice-of-completion system — but that
also means claimants who keep working intermittently, or who confuse "last
billed" with "last furnished," can miscalculate their own deadline. On
larger jobs, subcontractors who skip the 15-day Notice to Lien Agent don't
lose their lien outright, but a mortgage or refinance the owner records
first can leapfrog them in priority — a loss that isn't obvious until a
foreclosure sale doesn't leave enough money to reach every lienholder.

Common questions

I'm a subcontractor with no contract with the owner — can I still get a
lien on the property itself?
Only by subrogation under § 44A-23, and only up to the amount the owner
still owes the contractor. Your baseline remedy is a lien on funds under
§ 44A-18, reachable by serving written notice on whoever holds the money you're owed.

Do I need to notify anyone before I start work to protect my lien?
Not to have lien rights at all — but on a project big enough to require a
designated lien agent, sending a Notice to Lien Agent within 15 days of
first furnishing work protects your priority against a later mortgage or
sale, even though it isn't required to file the lien itself.

What starts my 120-day and 180-day clocks?
The same date for both: the last day you personally furnished labor or
materials at the site, not the date the whole project wrapped up and not
the date you were last paid.
