A notice of commencement is a legal document used in construction to officially mark the start of a project, set the formal start date, and identify the key parties involved (like the owner, contractor, and lender). It is usually recorded with the local government (often the county recorder or similar office) and may also need to be posted visibly at the job site.

What is a notice of commencement?

At its core, a notice of commencement is a construction project kickoff document that:

  • States that work has begun or will soon begin on a specific property.
  • Establishes the official project start date, which many legal deadlines are calculated from (like lien and lawsuit time limits).
  • Lists important details, such as the property owner, contractor, and often the lender or surety, plus a basic description of the work.

Think of it as the formal “announcement” to the world and to the local authorities that this particular construction job is now underway and who is involved.

Why is it important?

A notice of commencement plays a big role in managing risk and payments on construction projects.

Key purposes include:

  • Payment rights & liens:
    • It helps start the “clock” for mechanics lien deadlines and other legal time frames tied to the project start date.
* It provides a clear record that can protect both owners and contractors in case of nonpayment or disputes.
  • Transparency for stakeholders :
    • Everyone can see who owns the property, who the general contractor is, and sometimes who the lender and surety are.
* This helps subcontractors and suppliers know where to send notices and who is responsible for payment.
  • Government notice :
    • It tells the state, county, or local government that construction is starting at a particular location, with defined parties and scope of work.

In many places, filing and posting the notice is mandatory for certain types of projects or above certain dollar thresholds (for example, Florida requires it for permitted work over 5,000 dollars under its lien laws).

What information does it usually include?

While exact requirements vary by state or locality, a typical notice of commencement will contain:

  • Legal name and address of the property owner.
  • Property address and sometimes a legal description of the property.
  • Name, address, and contact information of the general contractor.
  • Brief description of the project or improvements (e.g., “new residential building,” “interior renovation,” “roof replacement”).
  • Start date (and sometimes expected completion date) of the project.
  • Lender information, if there is a construction loan.
  • Surety or bond information, if a bond is involved.
  • Signature of the owner (or sometimes an authorized representative), and in some states, a notarization requirement.

Some jurisdictions also require that the notice list the person to whom notices should be sent (for example, the owner’s designated agent).

How and where is it filed or posted?

The process also depends on local law, but generally you’ll see the same basic pattern.

  1. Prepare the form
    • Use the exact form required for your state or county; many areas have standardized templates.
 * Collect all required information before filling it out (owner details, contractor, property description, dates, etc.).
  1. Sign and notarize (if required)
    • Some states, such as Florida, require the notice of commencement to be signed by the owner and notarized.
  1. Record with the proper office
    • It is usually recorded in the county where the property is located (often the county recorder, clerk, or similar).
    • Many offices now allow electronic filing, mail-in filing, or in-person recording.
  1. Post at the job site
    • In many states, you must post a copy of the notice of commencement at the job site in a visible (conspicuous) location.
 * Failing to post it properly can cause legal disputes about whether notice was adequate.

Some services and platforms exist specifically to help contractors and owners e-file and manage notices of commencement and related documents.

Where is a notice of commencement used?

A notice of commencement is most commonly discussed in the context of U.S. construction projects, especially in states with detailed mechanics lien laws.

  • States with specific NOC statutes :
    Several states have formal legal procedures and forms for notices of commencement, including specific deadlines and strict compliance requirements.
  • Project types :
    • Residential, commercial, and industrial construction jobs may all use a notice of commencement when required by law or contract.
    • Some jurisdictions only require it above certain project values or where a permit is needed.

Because requirements are highly state-specific, owners and contractors are often advised to consult local statutes or a construction attorney before filing.

Mini example: A homeowner’s renovation

Imagine a homeowner planning a major renovation with a general contractor:

  • The contractor prepares a notice of commencement listing the homeowner as owner, the contractor as general contractor, the property address, a short description of the renovation, and the anticipated start date.
  • The homeowner signs it, has it notarized, and the document is recorded with the county.
  • A copy is then posted in a visible place at the job site (for example, on a fence or near the main entry).
  • Subcontractors and suppliers can use the information in that notice to send preliminary notices or protect lien rights, and later any dispute about timing or parties can be checked against the recorded document.

Quick SEO-style notes (for your post)

  • Core keyword: what is a notice of commencement
  • Secondary angles you can mention:
    • How it affects lien rights and payment protections.
* State-specific rules and deadlines (e.g., Florida’s requirement for jobs over 5,000 dollars).

* Practical tips: gather info early, use the right form, and post the notice conspicuously on site.

You can also add a short disclaimer like: “This is general information, not legal advice. For specific projects, check your local laws or talk to a construction lawyer.”

TL;DR: A notice of commencement is a recorded and often posted document that officially starts a construction project, sets the legal start date, and lists key participants, which in turn helps manage lien deadlines, payment rights, and transparency for everyone involved.
