Ohio Mechanic Lien Law Overview
Last updated April 2026 · Reviewed by Thomas Emalfarb, Esq.
Ohio construction mechanic lien rights are governed by Ohio Revised Code Annotated §1311.01 through §1311.22. This statutory framework protects the payment rights of contractors, subcontractors, materialmen, and laborers who perform work or furnish materials for the improvement of real property in Ohio. Mechanic Lien filing deadlines vary significantly depending on the type of construction project.
A critical first step under Ohio mechanic lien law is obtaining a copy of the Notice of Commencement from the owner, contractor, or upper-tier subcontractor or materialman. There are statutory penalties for failure to furnish the Notice of Commencement after a request. This document establishes the framework for all subsequent notice and mechanic lien filing requirements on the project.
Subcontractors and materialmen not in direct privity with the owner must serve a Notice of Furnishing upon the owner and contractor within 21 days of commencing work or furnishing materials. No mechanic lien rights exist for work performed or materials furnished prior to 21 days before serving the Notice of Furnishing. Laborers and those working on owner-occupied residential construction contracts and railroads are exempt from this requirement.
Ohio also provides separate remedies for public works projects: a Mechanic Lien on Public Funds under §1311.25-.32 and Payment Bond claims under §5525.15 and §153.54-.57. Ohio has strong prompt pay provisions effective for all contracts entered into after April 10, 1991, requiring payment within 10 days of receipt with 18% per annum interest for late payment.
Ohio Notice Requirements
Notice obligations that must be satisfied before filing a mechanic lien in Ohio.
Ohio requires subcontractors, sub-subcontractors, and material suppliers who do not have a direct contract with the property owner to file a Notice of Furnishing with the county recorder and serve it on the property owner and general contractor within 21 days of first furnishing labor, materials, or services (O.R.C. §1311.05). Failure to file within 21 days limits the lien to labor or materials furnished on or after the 21-day lookback period — effectively eliminating recovery for the first 21 days of work.
Property owners may file a Notice of Commencement with the county recorder before construction begins (O.R.C. §1311.04). When a Notice of Commencement is filed, it triggers the 21-day obligation for subcontractors and suppliers to serve their Notice of Furnishing. The Notice of Commencement must be posted at the project site and a copy filed with the county recorder.
For Ohio public projects, the general contractor must provide a payment bond. Subcontractors and suppliers must give written notice of their claim to the public authority and the general contractor within 90 days of last furnishing to preserve payment bond rights under O.R.C. §153.56. Failure to provide timely notice forfeits bond claim rights.
