Preliminary notices in Alaska

Alaska has a notice of right to lien for subcontractors and suppliers, which is optional but recommended. We don't show a single deadline for it: recording or delivering a notice of right to lien protects against owner payments made before it. Verify with the state statute.

Lien filing deadline in Alaska

If the GC hired you, you have 120 days after your last day furnishing labor or materials to record a mechanics lien in Alaska, about 30 days longer than the national median of 90 days (counted from last furnishing on a sample job). 9 of the 51 jurisdictions we track use this same lien deadline.

15 days after the owner records a notice of completion, if that is earlier.

The clock starts on your last day furnishing labor or materials under your contract. In many states, warranty visits and punch list work done mainly to extend the deadline don't restart it, so use your last day of real contract work.

Deadline to sue on the lien

To keep the lien alive you must sue to enforce it within 6 months after recording the lien. If you record on the last possible day, that is about 302 days after your last day on the job, about 63 days shorter than the national median of 365 days. 19 of the 48 jurisdictions we track have a shorter overall time to sue and 27 have a longer one.

Because the clock counts from recording, recording early also moves the lawsuit deadline earlier.

Can be extended by recording an extension before it expires.

How Alaska compares

Days are counted on a sample job with the lien recorded on its last allowed day, so states that count from recording or from completion can be compared with those that count from your last day on site. The median is across the jurisdictions with a dated rule on file.

Alaska deadlines vs the national median
Record the lien (from last day)
Alaska: 120 days
National median: 90 days
Sue to enforce (from last day)
Alaska: 302 days
National median: 365 days

Public and federal projects

Public property can't be liened, so subcontractors and suppliers on state and local public jobs in Alaska claim against the GC's payment bond instead. We haven't reduced Alaska's bond claim deadlines to one set of numbers, because they vary by agency and project. The governing law is Alaska Stat. §36.25.010. Verify the notice and suit deadlines with the statute and the bond itself before the job starts.

Federal jobs in Alaska follow the Miller Act instead of state law: those hired by a sub or supplier give the prime contractor notice within 90 days of their last furnishing, and suit is due within 1 year, in federal court. Prime contractors on federal work have no lien or bond claim.

Retainage and prompt payment in Alaska

We haven't reduced Alaska's retainage and prompt payment rules to single numbers yet: they depend on the agency, the contract size or the contract date. Rather than guess, the table shows "Verify" and the statutes to read are Alaska Stat. §36.90.200 to .250 (public); Alaska Stat. §08.18 (contractors). Your contract's payment terms still matter, and the federal rules below apply on federal work.

Not legal advice. Retainage and prompt payment rules differ by agency, contract size and contract date, and change often. Confirm the rules with the current statute, your contract and a construction attorney before relying on them.

Worked example: an electrical sub in Alaska

An electrical subcontractor hired by the GC on a private distribution warehouse in Alaska starts work on March 2, 2026 and last furnishes on July 17, 2026. The project is completed on August 28, 2026. Run through Alaska's rules, those dates give:

Deadlines for the worked example in Alaska
DeadlineDateCounted from
Record the lien November 14, 2026 Weekend Last furnishing
Sue to enforce the lien May 14, 2027 Lien recording
Notice of right to lien Verify with state statute No single date

The first deadline on the calendar is “Record the lien” on November 14, 2026.

One date lands on a weekend (November 14, 2026). Not every state rolls a deadline to Monday, so the safe move is to record or serve by the Friday before.

Rows marked "Verify" depend on facts or readings we can't settle for you, and rows without a date have no single number in the statute. Check them against Alaska Stat. §34.35.050 to .120.
