In Plain English
Quick Answer
A written notice from a sub or supplier to the property owner saying they're working on the project and intend to protect their right to get paid.
Definition
Definition
A notice to owner (NTO) is a document sent by a subcontractor, sub-subcontractor, or material supplier to the property owner and general contractor informing them that the sender is performing work or furnishing materials to the project and intends to preserve its lien rights. Many states require subcontractors below the first tier to serve an NTO within a statutory deadline (often 45 days from first furnishing) as a prerequisite to filing a valid mechanic's lien. The NTO alerts the owner so they can ensure funds reach lower-tier parties.
Context
Why It Matters in Bidding
An NTO is a payment-security mechanism, not a bidding document, but estimators on the sub side must budget the administrative time and tracking to serve it correctly on every qualifying job. Missing the statutory deadline can void lien rights entirely, turning a routine collection into an unsecured debt and exposing thin margins to nonpayment risk. On the GC and owner side, receiving NTOs signals which lower-tier parties are on the job and informs lien-waiver tracking before releasing progress payments.
Example
Example
A drywall subcontractor's office manager serves a Notice to Owner within 40 days of delivering the first load of board to a strip-mall job, preserving the company's lien rights even though it contracts only with the GC and never deals with the owner directly.

FAQ
Questions Contractors Ask
Who has to send a Notice to Owner?
Generally parties without a direct contract with the owner, such as subcontractors, sub-subcontractors, and material suppliers, must serve one to preserve lien rights. Requirements vary by state, and prime contractors who contract directly with the owner usually do not need to send an NTO because the owner already knows they are on the job.
What happens if you miss the Notice to Owner deadline?
Missing the statutory window, often 45 days from first furnishing labor or materials, typically forfeits your ability to file a valid mechanic's lien. You may still pursue payment through breach-of-contract or other remedies, but you lose the leverage of a lien against the property, which significantly weakens collection efforts.
Is a Notice to Owner the same as a mechanic's lien?
No. The NTO is a preliminary notice served early in the project that preserves the right to lien later if you go unpaid. The mechanic's lien is the actual claim recorded against the property after nonpayment. Many states require the NTO as a prerequisite before a lower-tier party can record a valid lien.
