To file a mechanic’s lien in Ohio, you record a sworn lien affidavit with the county recorder in the county where the property sits, then serve a copy on the property owner. If you’re a subcontractor or supplier, you have preliminary notice steps to handle first. Every step runs on a strict clock, and missing any one of them can void the lien even when the debt is real.
Who Can File
Contractors, subcontractors, laborers, and material suppliers who perform work or furnish materials for an improvement on private property in Ohio have potential lien rights.1Ohio Legislative Service Commission. Ohio Revised Code 1311.02 – Lien of Subcontractor, Laborer or Materialman Government-owned property is off limits; public and federal projects use bond claims instead, covered at the end of this article.
Your role changes what you have to do. A general contractor with a direct contract with the owner skips the Notice of Furnishing step. A subcontractor or supplier without that direct contract has to serve one, and quickly.
Step 1: Check for a Notice of Commencement
Before you do anything else, look up whether the owner recorded a Notice of Commencement with the county recorder. That document identifies the owner, the property, the general contractor, and the owner’s designated agent for notices.2Ohio Legislative Service Commission. Ohio Revised Code 1311.04 – Recording Notice of Commencement It’s the source of the addresses you need for Step 2.
If no Notice of Commencement was ever recorded, subcontractors and suppliers are not required to serve a Notice of Furnishing at all and can proceed directly to the affidavit when the time comes.3Ohio Legislative Service Commission. Ohio Revised Code 1311.05 – Subcontractor or Material Supplier Notice of Furnishing Don’t guess about this. Check the recorder’s records.
Step 2: Serve a Notice of Furnishing (Subcontractors and Suppliers)
If a Notice of Commencement exists, you have 21 days from the first day you perform labor or furnish materials to serve a Notice of Furnishing on both the owner’s designated agent and the general contractor named in the Notice of Commencement.3Ohio Legislative Service Commission. Ohio Revised Code 1311.05 – Subcontractor or Material Supplier Notice of Furnishing
Miss the 21 days and the notice can still be served, but it only protects amounts owed for the 21 days immediately before service and any work after. Everything earned before that window is unprotected. This is where most subcontractor liens quietly fail: nobody thinks about lien rights until a payment problem two months in, and by then the protection for the earliest work is already gone.
General contractors in privity with the owner do not serve a Notice of Furnishing.
Step 3: Prepare the Lien Affidavit
The filing document is the Affidavit for Mechanic’s Lien. It must be sworn under oath before a notary and contain:4Ohio Legislative Service Commission. Ohio Revised Code 1311.06 – Affidavit – Time Period for Filing – Contents
- The amount owed, after any legal setoffs or credits.
- A legal description of the property, available from the county auditor’s website or the deed.
- The name and address of the party who hired you.
- The name of the owner, part owner, or lessee, if known.
- Your name and address as the lien claimant.
- The first and last dates you performed labor or furnished materials.
The statute provides a standard form, but you’re not required to use it verbatim. Address inaccuracies won’t invalidate a properly recorded affidavit. The number is different. Inflating the amount, especially with disputed extras or unapproved change orders, invites a challenge from the owner and can expose you to liability. Claim the actual contract balance minus legitimate credits.
Step 4: File Within 60 or 75 Days
File the notarized affidavit with the county recorder in the county where the property is located. The deadline runs from the last day you actually performed labor or furnished materials on the project, not from your last invoice or the date a dispute arose:4Ohio Legislative Service Commission. Ohio Revised Code 1311.06 – Affidavit – Time Period for Filing – Contents
- Residential projects (one- or two-family dwellings and residential condominiums): 60 days.
- Commercial projects: 75 days.
These deadlines don’t bend. One day late voids the lien. Calendar the date from your genuinely last day on the site and leave yourself several days of buffer to get the affidavit drafted, notarized, and delivered to the recorder.
Expect a recording fee. In Ohio the base recording fee is roughly $34 to $44 for the first two pages, plus $8 for each additional page, though exact amounts vary by county.5Mahoning County, OH. Schedule of Fees
Step 5: Serve the Owner Within 30 Days
Recording is only half the job. Within 30 days after the affidavit is filed, you have to serve a copy on the property owner using the methods specified in the statute. Certified mail with return receipt is the standard choice because it creates proof of service. If you can’t reach the owner through the ordinary methods, you get an extra 10 days after the 30-day window to post the affidavit in a conspicuous place on the property.6Ohio Legislative Service Commission. Ohio Revised Code Chapter 1311 – Liens – Section 1311.07
What Happens After the Lien Is Filed
An Ohio mechanic’s lien stays in force for six years from the recording date. If you don’t file a foreclosure lawsuit within that period, the lien expires on its own.7Ohio Legislative Service Commission. Ohio Revised Code 1311.13 – Attaching of Liens – Continuance and Priority The lien itself doesn’t force payment. It creates leverage because the owner can’t sell or refinance with a clean title while it sits on the record.
The owner can compress the timeline. Ohio law lets the owner serve you with a notice requiring you to commence suit. Once you receive it, you have 60 days to file a foreclosure lawsuit. Miss that window and the lien becomes void and the property is discharged from the claim.8Ohio Legislative Service Commission. Ohio Revised Code Chapter 1311 – Liens – Section 1311.11 The debt still exists, but the leverage is gone. Treat that notice as urgent.
Once you’re paid or a judgment satisfies the debt, you have 30 days to record a release with the same county recorder. Fail to release on time and you become liable to the owner for damages caused by the delay, up to the full amount of the lien plus costs.9Ohio Legislative Service Commission. Ohio Revised Code Chapter 1311 – Liens – Section 1311.20 Some counties want a specific format for the release, so ask the recorder before you draft it.
Public and Federal Projects
You can’t file a mechanic’s lien on government-owned property in Ohio. State and local public improvement projects use a statutory bond claim process against the contractor’s payment bond instead.
Federal projects fall under the Miller Act. If you supplied labor or materials to a federal project and haven’t been paid within 90 days of your last day of work, you can sue on the payment bond. Subcontractors without a direct contract with the general contractor must send written notice to the general contractor within 90 days of their last day of work, and any suit must be filed within one year of that date, in the U.S. District Court for the district where the project is located.10Office of the Law Revision Counsel. 40 USC 3133 – Right of Action on Payment Bond
Mistakes That Kill an Ohio Lien
Most failed Ohio mechanic’s liens fail on paperwork and timing rather than on the merits. The recurring errors:
- Missing the 21-day Notice of Furnishing on a project with a recorded Notice of Commencement. Late notice loses protection for earlier work; no notice loses everything.
- Filing the affidavit after the 60- or 75-day deadline, usually because someone counted from the final invoice instead of the final day of work.
- Recording the affidavit but not serving the owner within 30 days.
- Ignoring an owner’s notice to commence suit and missing the 60-day window to file foreclosure.
- Overstating the claim by loading in disputed extras or unapproved change orders.
The best time to think about lien rights is before the first day of work. Pull the Notice of Commencement, calendar the 21-day Notice of Furnishing deadline, and track your first and last dates on the job from day one. Every deadline in this process runs from something you did or didn’t do on the site, and the record you keep from the start is what makes the filing at the end possible.
