What Is a Preliminary Notice (and When to Send It)?

A preliminary notice (often called a “prelim,” “notice to owner,” or similar) is a document sent early in a project to inform owners, GCs, and lenders that you’re furnishing labor or materials. Sending it on time preserves your mechanics lien rights in many states and keeps payment paperwork clean. Because rules vary by state, treat this as practical guidance—not legal advice.

Why Preliminary Notices Matter

Prelims reduce surprise, help owners confirm who’s on site, and protect your right to secure payment if problems arise.

  • Preserves your ability to file a mechanics lien if unpaid (where required)
  • Improves visibility for owners/lenders → fewer pay-app holdbacks
  • Creates a documented start date for your participation
 

Who Sends It—and To Whom?

Subcontractors and suppliers are most often required to serve prelims; some states also require GCs. Recipients typically include:

  • Owner (or owner’s agent)
  • General Contractor
  • Lender (if applicable)

Tip: Confirm exact parties from the contract, permit, or a recorded Notice of Commencement (where used).

 

Deadlines & Timing (High-Level)

Timing is jurisdiction-specific, but the pattern is similar: serve the notice early—often within a set number of days after first furnishing labor or materials.

  • Common windows: 10–30 days after first delivery/work (varies)
  • Late service may limit rights to work furnished after the notice—or forfeit rights entirely
  • Keep proof of mailing/service and exact dates

Always check your state’s statutes and contract terms.

 

What to Include in a Preliminary Notice

Be specific and consistent with your contract and pay apps.

  • Project name and job address
  • Owner, GC, and lender (legal names)
  • Your legal entity, license # (if required), contact info
  • Description of labor/materials you’ll furnish
  • Estimated amount (if required) and first furnishing date
  • Any required statutory warnings or disclosures
 

Service Method & Proof

Follow your jurisdiction’s approved service methods and keep receipts.

  • Certified mail/return receipt or other approved service
  • Retain mailing receipts, tracking, and signed green cards
  • Log service dates and recipients in your project record
 

Tie Notices to Billing & Compliance

Make prelim tracking part of your normal billing workflow.

 

Common Pitfalls (and Easy Fixes)

Small gaps can undermine your rights—tighten these early.

  • Missing recipients: verify owner/GC/lender names and addresses
  • Late service: set reminders based on your first furnishing date
  • No proof: keep mailing receipts and delivery confirmations
  • Wrong entity names: match legal names on contracts and permits

FAQs About Preliminary Notices

 

Do all states require a preliminary notice?

No. Many do, especially for subs and suppliers, but details vary. Check your state’s rules and your contract.

What’s the difference between a Preliminary Notice and a Notice of Commencement?

A Preliminary Notice is served by contractors/subs to announce participation; a Notice of Commencement is usually recorded by the owner/GC to start the project timeline and list key parties.

Can I send a prelim late?

Sometimes—but your lien rights may be limited to work after the service date, or lost entirely in strict jurisdictions. Serve as early as possible and keep proof.
