Preliminary notices in Kansas
Kansas 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 owner often learns about your claim only when the lien is recorded.
Lien filing deadline in Kansas
If the GC hired you, you have 3 months after your last day furnishing labor or materials to record a mechanics lien in Kansas, about the same as the national median of 90 days (counted from last furnishing on a sample job). 28 of the 51 jurisdictions we track have a shorter lien deadline and 22 have a longer one.
Can be extended one month by filing a notice of extension before the deadline.
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.
If you're the GC, in contract with the owner, you have 4 months after your last day furnishing labor or materials instead.
Deadline to sue on the lien
To keep the lien alive you must sue to enforce it within 12 months after recording the lien. If you record on the last possible day, that is about 457 days after your last day on the job, about 92 days longer than the national median of 365 days. 34 of the 48 jurisdictions we track have a shorter overall time to sue and 13 have a longer one.
Because the clock counts from recording, recording early also moves the lawsuit deadline earlier.
How Kansas 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.
- Record the lien (from last day)
- Kansas: 92 daysNational median: 90 days
- Sue to enforce (from last day)
- Kansas: 457 daysNational median: 365 days
Public and federal projects
Public property can't be liened, so subcontractors and suppliers on state and local public jobs in Kansas claim against the GC's payment bond instead. We haven't reduced Kansas's bond claim deadlines to one set of numbers, because they vary by agency and project. The governing law is Kan. Stat. §60-1111. Verify the notice and suit deadlines with the statute and the bond itself before the job starts.
Federal jobs in Kansas 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 Kansas
We haven't reduced Kansas'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 Kan. Stat. §16-1901 to -1908 (Fairness in Public and Private Construction Contract Acts). 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: a plumbing sub in Kansas
A plumbing subcontractor hired by the GC on a private bank branch in Kansas starts work on March 2, 2026 and last furnishes on July 17, 2026. The project is completed on August 28, 2026. Run through Kansas's rules, those dates give:
| Deadline | Date | Counted from |
|---|---|---|
| Record the lien | October 17, 2026 Weekend | Last furnishing |
| Sue to enforce the lien | October 17, 2027 Weekend | Lien recording |
The first deadline on the calendar is “Record the lien” on October 17, 2026.
2 dates land on a weekend (October 17, 2026, October 17, 2027). Not every state rolls a deadline to Monday, so the safe move is to record or serve by the Friday before.

Not legal advice. Lien and bond claim rules change and have exceptions for project type, contract terms and how notices are served. Confirm every deadline with the current statute or a construction attorney in the project's state before relying on it. Rules shown as "Verify with state statute" have exceptions or variations we could not reduce to one number.
