What Is a Notice of Commencement (and How Does It Affect Deadlines)?

A notice of commencement (NOC) is a document recorded by the owner or GC. It goes on file at or before the start of construction.

It names the project, property, key parties, and start date. In many states it starts the clock for preliminary notices and sets who must be served. So it affects your lien rights and payment paperwork.

Why does a notice of commencement matter?

The NOC works like a project directory and a timing trigger. It feeds both your compliance and your billing.

• Lists the owner, GC, and lender, plus the project address, for correct service
• Sets the official start date for notice and lien timelines
• Helps owners and lenders track who is furnishing labor and materials
• Cuts pay-app delays by aligning documents with the right parties

What is in a notice of commencement?

Details vary by state, but most NOCs cover the same ground. Use it to confirm names and the property description.

• Property or legal description and the project address
• The owner legal entity and contact information
• The GC or prime contractor and the lender, if any
• Effective or start date, and sometimes the bonding company
• Instructions for serving preliminary notices

How does the NOC affect notices and lien deadlines?

Use the NOC to drive your compliance calendar. It clarifies recipients and can affect timing. Deadlines still vary by state.

• Preliminary notice windows often run from your first furnishing, and the NOC clarifies recipients
• Some states adjust lien filing deadlines around the NOC or completion
• If the NOC lists a specific address or service method, follow it exactly

Where do you find the NOC?

Get the NOC early so your paperwork is accurate. There are two reliable sources.

• Ask the owner or GC for a copy at award or precon
• Check the county recorder or clerk where the property sits
• Confirm the parties and property description match your contract

What if the information changes mid-project?

Names, lenders, or contacts can change after the job starts. Keep your records current so notices reach the right parties.

• Request an updated NOC or a formal notice of change
• Update your prelim and lien contact list and pay-app cover sheet
• Note the change in your project record for future submissions

When should you check the NOC?

Check the NOC before you serve any notice or send a pay app. Treat it as the source of truth for parties and addresses.

Pull it at award, then again before each compliance step. Re-check it if the project changes hands or adds a lender. A stale NOC leads to misdirected notices and lost time.

• At award or precon, before you furnish work
• Before serving a preliminary notice or NOI
• Before submitting a pay app or lien waiver
• Any time ownership or lender info changes

What are common NOC mistakes?

A few checks prevent most compliance headaches. Build them into your routine.

• Wrong party names, so copy legal names from the NOC and contract
• Missed deadlines, so calendar windows from first furnishing and keep the NOC on file
• Service to the wrong address, so use the addresses listed in the NOC
