Preliminary notices in North Dakota
North Dakota is one of the states with no general preliminary notice for subcontractors on commercial work in our summary. That doesn't mean you can skip paperwork: the lien itself still has a hard deadline, and the other notices below still apply.
Before recording, GCs, subcontractors and suppliers send a notice of intent to lien at least 15 days before the last day to record the lien. Because it counts back from the deadline, waiting until the last week can leave you too late to record at all.
Lien filing deadline in North Dakota
If the GC hired you, you have 90 days after your last day furnishing labor or materials to record a mechanics lien in North Dakota, about the same as the national median of 90 days (counted from last furnishing on a sample job). 23 of the 51 jurisdictions we track use this same lien deadline, which makes it the most common rule.
A lien can be recorded later (up to 3 years) but loses priority against buyers and lenders. Verify this with the statute before relying on it.
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 36 months after your last day furnishing labor or materials. That comes to about 1096 days after your last day on the job, about 731 days longer than the national median of 365 days. 45 of the 48 jurisdictions we track have a shorter overall time to sue and 2 have a longer one.
North Dakota counts the suit deadline from last furnishing, not from recording, so recording late eats into the time left to sue.
Or 30 days after an owner's written demand to sue.
How North Dakota 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.

Public and federal projects
Public property can't be liened, so subcontractors and suppliers on state and local public jobs in North Dakota claim against the GC's payment bond instead. We haven't reduced North Dakota's bond claim deadlines to one set of numbers, because they vary by agency and project. The governing law is N.D. Cent. Code §48-01.2-10. Verify the notice and suit deadlines with the statute and the bond itself before the job starts.
Federal jobs in North Dakota 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 North Dakota
We haven't reduced North Dakota'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 N.D. Cent. Code §48-01.2-13 (public). Your contract's payment terms still matter, and the federal rules below apply on federal work.
| Public work | Private work | Federal work | |
|---|---|---|---|
| Retainage cap | Verify | Verify | 10% |
| Release | Verify with state statute | Verify with state statute | Released with final payment, or earlier once progress is satisfactory. |
| GC pays subs within | Verify | Verify | 7 days |
| Late-payment interest | Verify | Verify | Treasury prompt payment rate (reset every January and July) |
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 North Dakota
An electrical subcontractor hired by the GC on a private apartment building in North Dakota starts work on March 2, 2026 and last furnishes on July 17, 2026. The project is completed on August 28, 2026. Run through North Dakota's rules, those dates give:
| Deadline | Date | Counted from |
|---|---|---|
| Notice of intent to lien (15 days before recording) | September 30, 2026 | The lien deadline |
| Record the lien | October 15, 2026 Verify | Last furnishing |
| Sue to enforce the lien | July 17, 2029 Verify | Last furnishing |
The first deadline on the calendar is “Notice of intent to lien (15 days before recording)” on September 30, 2026.
Rows marked "Verify" depend on facts or readings we can't settle for you. Check them against N.D. Cent. Code §35-27-01 to -28.
