A mechanic's lien is a legal document used by contractors, subcontractors, and suppliers to secure payment for work completed on a construction project. Filing a mechanic's lien essentially states that:
- You're owed money for services provided
- You're expecting payment by a specific date
- You'll proceed with litigation if you don't receive payment by that date
While a lien is in place, it restricts the owner from selling, refinancing, or transferring the property without paying you. That pressure makes liens one of the most powerful payment tools available—especially for subcontractors and suppliers.
Mechanic's lien laws vary significantly by state, with different rules governing who can file a lien, what notices are required, and timelines for filing and enforcement. This guide covers the essentials of Ohio's mechanic's lien laws to help you protect your right to payment.

Ohio mechanic's lien rights are governed by Ohio Revised Code Chapter 1311 and apply only to private construction projects. (Public projects cannot be liened. If you're unpaid on public work, payment disputes are handled through bond claims or public improvement fund remedies under Ohio's Little Miller Act.)
Ohio's lien system hinges on one key document: the Notice of Commencement. When an owner properly records and posts this notice, it triggers additional obligations for subcontractors and suppliers—most important of which is the requirement to serve a Notice of Furnishing to preserve full lien rights.
With that framework in mind, let's dive in.
In Ohio, lien rights are broad and cover almost anyone who contributes to a permanent improvement, including:
- General (original) contractors
- Subcontractors and lower-tier subcontractors
- Material suppliers
- Laborers and tradespeople
- Design professionals, such as architects, engineers, and surveyors (when their services qualify as lienable labor)
- Machinery and equipment lessors
To qualify for a lien in Ohio, the work must provide a permanent "improvement" to the real property, meaning labor or materials furnished for the construction, alteration, or repair of a structure O.R.C. §§ 1311.01, .02, .03).
Here are some examples of what’s usually considered lienable and what isn’t.
Lienable Work in Ohio
- Construction, alteration, repair, or demolition of buildings or structures
- Excavation, grading, ditching, and landscaping
- Drilling or construction of oil and gas wells
- Materials, fuel, or supplies furnished for use in the improvement
- On-site rental equipment and machinery
- Architectural, engineering, and surveying services tied to the improvement
- Construction or repair of private roads, sidewalks, sewers, and similar improvements
Non-Lienable Work in Ohio
- Work on public projects
- Work performed without the owner’s express or implied consent
- Reusable tools or equipment that are not valueless upon return
- Purely administrative or clerical services
Ohio applies different lien filing deadlines depending on whether the project is commercial or residential. Residential projects—defined as one- or two-family dwellings—carry a shorter filing window than commercial work.
Regardless of project type, make sure you’ve met any notice or preliminary requirements that apply to your role (see table above).
Deadline to File
- Commercial projects: All claimants must file within 75 days from the date on which the last labor was performed or materials were furnished.
- Residential projects: All claimants must file within 60 days from the date on which the last labor was performed or materials were furnished.
Filing Requirements
- Filing location: Record the Affidavit of Mechanic’s Lien with the county recorder's office for each county where the property is located.
- Form requirements: Ohio provides a statutory affidavit form under O.R.C. § 1311.06. The affidavit must include:
- The amount due after deducting all credits and setoffs
- A description of the property sufficient for identification
- The name and address of the party who hired you
- The name and address of the property owner
- The name and address of the lien claimant
- The first and last dates work or materials were furnished
- Verification: The lien must be signed by the claimant in front of a notary.
- Filing fee: Varies by county recorder.
Service Requirements
A copy of the recorded lien must be served on the owner within 30 days of filing via certified (or other receipted) mail. If the owner cannot be served, you have an additional 10 days to post it on the premises in a highly-visible place (O.R.C. § 1311.07(A)–(B)).
Recording a lien preserves your rights—but enforcement is how you get paid. Here’s what you must do to ensure you enforce your lien in Ohio.
Enforcement Requirements
- Enforcement deadline: You must file a foreclosure action within six years after the lien is recorded. If the owner files a Notice to Commence Suit, the enforcement deadline is slashed to 60 days.
- Filing location: Suit must be initiated in the Court of Common Pleas in the county where the property is located.
- Lien priority: Properly perfected mechanic’s liens generally take priority over liens or mortgages recorded after the Notice of Commencement. Laborer liens receive special statutory protection.
Lien Release Requirements
Once the debt is paid or otherwise satisfied, the claimant must record a written release or satisfaction of lien with the county recorder’s office. Failure to release a satisfied lien may expose the claimant to damages (O.R.C. § 1311.20).
- Unified workflow: Manage lien rights within your billing and collections workflow to keep payment context in one place.
- Automated compliance: Automatically track critical deadlines and milestones based on each state's lien laws.
- Meaningful visibility: View the lien protection status for each project to identify and mitigate risk.
- Document creation: Generate state-specific lien notices instantly using existing project data
- Integrated delivery: Send notices via certified mail directly from Siteline to streamline delivery.
Generally, yes. Ohio’s mechanic’s lien statutes do not contain a strict provision that automatically bars unlicensed contractors from filing. However, if your trade specifically requires a professional license, the lack of a license could be used to invalidate your case.
Yes, Ohio lien rights extend down the chain to subcontractors, lower-tier contractors, and material suppliers. As long as you were hired by someone with a contract for the improvement, you have lien rights—provided all notice and timing requirements are met.
Yes, but just the enforcement deadline. Ohio gives an owner (or other interested party) the ability to serve a Notice to Commence Suit. Once served, the lien claimant has 60 days to file a foreclosure lawsuit (rather than the standard six-year timeline—a huge jump).
No, Ohio does not require anyone to file a Notice of Intent (NOI) before filing a construction lien.
Yes, but only if the property owner records a Notice of Commencement. If they do, subcontractors and suppliers must serve a Notice of Furnishing within 21 days of first furnishing labor or materials to preserve their full lien rights.
If you miss this window, don't panic—you can still send a late notice, but your lien rights will only cover work performed in the 21 days immediately preceding the notice and everything you do afterward.
There is no statutory lien waiver form in Ohio, so parties are free to use any format they choose. We recommend brushing up on the specific rules in our Ohio lien waiver guide before your next project.
In Ohio, you can lien for the unpaid "price and value" of your work, which typically reflects:
- The remaining unpaid contract balance (including any retainage you’ve already billed for)
- Approved change orders
- The rental value of any on-site machinery and equipment
- Specially fabricated materials custom-made for the project
- Fuel and supplies consumed by machinery while performing work
You typically can’t include attorneys’ fees, interest, or overhead costs in the initial lien amount. And willfully overstating a lien in Ohio can invalidate it, so keep it reasonable and within the statute’s confines.
No. Ohio law recognizes lien rights for work performed under an express or implied contract, which includes verbal agreements. That said, we always recommend having a written agreement on file because it can make it easier to prove your case in court.
