A Notice of Commencement in construction is a document the property owner records with the county recorder or clerk of court before work begins on a private project. It names the owner, the general contractor, the construction lender, and any surety, and it is required in several states to establish the lien priority date and to put subcontractors and suppliers on notice of whom to contact about payment.
What the Document Is For
The Notice of Commencement (NOC) serves two audiences at once. For the owner, it creates a structured system that forces subcontractors and suppliers to send preliminary notices before they can claim lien rights. That gives the owner visibility into who is on the job and a chance to verify payments before a dispute turns into a lien. For sub-tier parties, the recorded NOC is the roadmap: it tells them where to send their notices and whom to name when protecting their right to payment.
Without a recorded NOC in a state that requires one, that system breaks down. The preliminary notice requirement often drops away, the owner loses the early warning, and lien priority becomes harder to sort out. The NOC is the anchor document that keeps obligations and protections on the same timeline.
When You Need to File One
Not every state requires a Notice of Commencement. The states with a mandatory filing include Florida, Georgia, Michigan, Nebraska, Ohio, and Iowa. Texas has a voluntary version called an Affidavit of Commencement, which the owner and general contractor may jointly file but are not required to. Many other states have no equivalent document and use different mechanisms to establish lien priority.
Among the states that require an NOC, the filing trigger also varies. Most require the owner to record the document before any physical work begins. Georgia allows up to 15 days after the contractor physically starts work. Some jurisdictions set a minimum project cost, typically around $2,500, below which the filing is not required; others apply the rule to every private improvement regardless of value.
Even where filing is optional, recording an NOC can establish a clear lien priority date and simplify later disputes. Contractors working across state lines should verify the rule at the project location, because the consequences of getting it wrong fall on the owner.
Information Required on the Form
The form itself is straightforward, but accuracy matters. A small error in the property description or a missing contractor name can weaken the protections the document is supposed to provide. Fields vary by jurisdiction, but most states require substantially the same information:
- The full legal property description from the deed, not just the street address. County assessor records or the original title documents are the most reliable sources.
- The name and address of the owner, and, if different, the fee simple titleholder or land contract vendee.
- The name and address of the general contractor performing the work.
- The name and address of any construction lender financing the project.
- If a payment bond exists, the surety company name, address, and bond number.
- A general description of the planned improvement, specific enough for someone unfamiliar with the project to identify the type of work.
- In some states, a designated agent within the state authorized to receive notices and legal documents for the owner.
The owner or an authorized agent must sign the form, typically in front of a notary public. Notary fees for construction documents generally run between $2 and $25. Official NOC forms are usually available through the local county clerk’s office or building department.
How to Record and Post It
Once the form is complete and notarized, the owner files it with the county recorder or clerk of court in the county where the property sits. Many counties now accept electronic filings through online portals, and walk-in filing remains available everywhere. Recording fees for a standard one-page document typically fall between $10 and $88 depending on the jurisdiction, with multi-page filings costing more.
Recording alone is not enough. Most states that require an NOC also require the owner to post a certified copy at the job site in a visible location, such as a permit board, temporary fencing, or the main entrance to the work area. The goal is to make the document accessible to any subcontractor or supplier who shows up on site, so they can identify the owner, contractor, and lender without searching public records. Some local building departments will not schedule inspections until a copy of the recorded NOC has been submitted to their office or uploaded to their permitting portal.
Timing is critical. The NOC generally must be recorded before construction begins. Filing after work has already started can undermine its effectiveness and, in some jurisdictions, create gaps in lien priority coverage. The document belongs on the pre-construction checklist alongside building permits and insurance certificates.
How It Affects Mechanics Lien Rights
The NOC’s most significant legal function is establishing the priority date for mechanics liens on the project. When a subcontractor or supplier eventually files a lien claim, that lien’s priority typically relates back to the recording date of the NOC rather than the date the individual claimant started work. All lien claims on the project share the same priority date, anchored to the NOC recording.
This relation-back principle matters in payment disputes. If a subcontractor files a lien six months into a project, the lien’s priority is measured against the NOC recording date, not the date that subcontractor first showed up. Any mortgage, sale, or other encumbrance recorded after the NOC is subordinate to the lien claims. Encumbrances recorded before the NOC take priority over later liens.
The NOC also triggers notice obligations for sub-tier parties. In many states, subcontractors and suppliers must serve a preliminary notice, often called a Notice to Owner or Notice of Furnishing, within a set number of days after beginning work. Deadlines vary, with 45 days common in some jurisdictions, and the clock starts when the subcontractor begins furnishing labor or materials. Missing that deadline can be a complete defense for the owner against a later lien claim, which is why the information on the NOC matters to everyone down the payment chain.
What Happens If You Skip the Filing
The consequences of not recording an NOC fall heaviest on the property owner, though subcontractors feel the effects too. When no NOC exists on record, the structured notice system collapses in ways that tend to increase everyone’s risk.
- Broader lien exposure for the owner. Without a recorded NOC, subcontractors and suppliers in many states no longer have to send preliminary notices before claiming lien rights, and the owner loses the advance warning that would normally identify who is working on the project and expecting payment.
- Uncertain lien priority. With no NOC to anchor the relation-back date, priority may instead be set by the date each individual lien is recorded, which creates a first-to-file scramble rather than an orderly system.
- Third-party filing at the owner’s expense. In some states, a mortgage holder or general contractor can record the NOC on the owner’s behalf if the owner fails to do so, and the owner becomes liable for the costs of gathering the information and filing the document.
- Inspection delays. Local building departments that require a recorded NOC before scheduling inspections will hold up the project until the filing is complete.
Expiration, Amendment, and Termination
A Notice of Commencement does not last forever. Most states set a default expiration period of one year from the recording date, though Ohio uses a four-year window. If the form allows the owner to specify a different expiration date, that date should match the expected project duration. An NOC that expires while work is still in progress leaves a gap in lien priority coverage.
When construction extends beyond the original period, the owner files an amended NOC. The amendment typically relates back to the original recording date, preserving the lien priority structure. Only one NOC should be active for a given improvement at any time; filing a second one without properly amending the first can create conflicting priority dates.
When the project wraps up, or when a lender needs a clean title for refinancing or sale, the owner files a Notice of Termination. This formally cancels the NOC and cuts off the period during which new lien claims can relate back to the original recording date. Termination requirements vary by state but generally include notifying all known lien claimants before the termination takes effect. Some states require published notice in a local newspaper, and the termination date cannot be earlier than a set number of days after recording.
The prerequisite before terminating: all parties who served preliminary notices must be paid in full. Filing a termination while subcontractors remain unpaid invites legal challenges and does not eliminate existing lien claims. It only prevents new ones from attaching.
Clearing the Notice for a Sale or Refinance
An active NOC on the property creates a problem for anyone trying to sell or refinance. Because the NOC sets the priority date for potential lien claims, title insurance companies list it as an exception on any policy issued while the notice remains effective. A buyer or lender looking at that policy sees an open-ended risk: subcontractors could still file liens that take priority over the new mortgage or ownership interest.
To clear the NOC from the title, the owner typically records a Notice of Termination along with a final contractor’s affidavit confirming that all parties have been paid. Title companies also commonly require unconditional final lien waivers from every subcontractor and supplier who served a preliminary notice during the project. If those waivers are not available, the title company may require the owner to sign an indemnity agreement holding the insurer harmless against future lien claims, a commitment that can carry real financial consequences if an unpaid subcontractor surfaces later.
Owners who collected lien waivers at each payment milestone can clear the title quickly. Owners who did not track waivers through the project often find themselves scrambling at closing, unable to prove that sub-tier parties were paid.
