Understanding Preliminary Notices in Ohio
Ohio uses a preliminary notice system. Here's what that means in plain English: when you start working on a construction project (or deliver your first batch of materials), you need to send a document called the “Notice of Furnishing” to certain people within 21 days.
Imagine you're an electrician hired to wire a new office building in Ohio. Your first day on the job site is March 1st. Under Ohio law, you need to send the Notice of Furnishing by 21 days later. This notice goes to the property owner. Send it on time to keep your lien rights active. This is the single most important compliance step on any Ohio project.
Who Needs to Send a Preliminary Notice in Ohio?
This applies to nearly everyone who works on a construction project and wants to protect their payment rights. That includes general contractors, subcontractors (electricians, plumbers, roofers, etc.), material suppliers (lumber, concrete, fixtures), equipment rental companies, laborers, architects and engineers, and surveyors. The specific rules — like who you need to notify and your deadline — depend on your role. Check the table below to see exactly what applies to you.
Why Preliminary Notices Matter
The Notice of Furnishing is what keeps your lien rights active in Ohio. It's standard paperwork — sending it on time protects your payment on every project.
Who Must Receive the Notice of Furnishing?
Who you need to notify depends on your role on the project. Here's a simple breakdown:
| If You Are A... | You Must Notify... |
|---|---|
| General Contractor | No notice typically required (direct contract with owner) |
| Subcontractor | Property Owner |
| Material Supplier | Property Owner, General Contractor |
| Laborer | Property Owner |
| Equipment Rental Company | Property Owner, General Contractor |
| Architect / Engineer / Surveyor | Property Owner |
How to Deliver the Notice in Ohio
Use one of the approved delivery methods below to make sure your notice is valid. Ohio accepts these methods:
Certified Mail — You send via USPS and get a green receipt card proving the notice was delivered. This is the gold standard because it creates clear proof of delivery.
Personal Delivery — You (or someone you designate) hand-deliver the notice directly to the recipient. Make sure to get a signed acknowledgment as proof.
Statutory Notice Language
Ohio law requires your Notice of Furnishing to include specific warning language. This isn't language you write yourself — it's exact wording specified by OH Rev. Code Ann. §§ 1311.01 et seq.. Using the wrong language (or leaving it out) can invalidate your notice. LienGrid automatically includes the correct statutory language for Ohio.
Owner Warning Language (excerpt from OH Rev. Code Ann. §§ 1311.01 et seq.)
