Florida Notice to Owner Deadlines: A Contractor's Quick Reference Guide

This guide provides a detailed, professional reference on Florida NTO deadlines, service requirements, and best practices to protect your lien rights under Florida Statute §713.06.

What Is a Notice to Owner?

A Notice to Owner (NTO) is a preliminary legal notice that certain lienors must serve on the property owner (and sometimes other parties) to inform them that they are furnishing labor, services, or materials to a construction project.

Serving an NTO preserves your right to later record a Construction Lien if you are not paid.

Key Facts

• The NTO is required only for parties without a direct contract with the owner, such as subcontractors and suppliers.

• The general contractor does not need to serve an NTO because they are already in privity with the owner.

• The NTO is a prerequisite to enforcing lien rights under Florida construction lien law.

Critical Deadline: The 45-Day Rule

The most important deadline in Florida's NTO process is the 45-day service window.

When Must You Serve the NTO?

You must serve the Notice to Owner:

• Before commencing work, or

• Within 45 days of first furnishing labor, services, or materials on the project.

The 45-day period begins on your first day of furnishing work or materials on that specific project, not when the overall project begins.

Examples

If you deliver materials on January 1, your NTO must be served by February 15 (Day 45).

If you begin work on March 10, you must serve the NTO by April 24.

What Happens If You Miss the Deadline?

• An NTO served after Day 45 is invalid.

• You lose your lien rights entirely for work furnished before the notice was served.

• Even if you have performed thousands of dollars of work, missing the deadline eliminates your right to lien.

Florida strictly enforces this deadline. There is no grace period.

When the 45-Day Clock Starts

Understanding the trigger date is essential because the 45-day deadline begins when you first furnish labor, services, or materials—not when the overall project starts.

The deadline begins:

• On the date of your first material delivery.

• On the first day labor is performed.

• When work begins on manufacturing specially fabricated materials.

• On the first day a subcontractor begins installation work.

For specially fabricated materials, the clock starts when fabrication begins, not when the materials are delivered to the project site.

Who Must Receive the Notice to Owner?

The NTO must be served on:

• The property owner (or the owner's authorized representative)

• The contractor with whom you contracted (if applicable)

• Any other party named in the Notice of Commencement (NOC)

How to Identify Required Recipients

• Obtain a copy of the project's Notice of Commencement from county records.

• Review the NOC carefully for additional parties who must receive the NTO.

Proper Method of Service

Florida law requires strict compliance with service requirements.

You may serve a Notice to Owner using one of the following methods:

• Certified Mail with Return Receipt Requested (RRR)

• Global Express Guaranteed through the U.S. Postal Service

• Personal delivery with a signed receipt or written proof of service

Important: Regular mail is not an acceptable service method.

Florida Statute §713.06 specifically requires approved delivery methods that provide proof of service.

Additional Timing Requirements

Before Final Payment

The NTO must be served before the owner makes final payment to the prime contractor who has delivered a final payment affidavit.

If final payment has already been made, the NTO is ineffective even if served within 45 days.

Specialty Materials

If you are furnishing specially fabricated materials, the 45-day period begins when work starts on manufacturing those materials.

Common Mistakes to Avoid

The following mistakes frequently result in lost lien rights.

Assuming Day 45 Is the Last Mailing Day

Waiting until the last day can create delivery issues that jeopardize your lien rights.

Sending the NTO by Regular Mail

Regular mail does not satisfy Florida's statutory service requirements and may invalidate your notice.

Confusing the Project Start Date with Your Start Date

The deadline is calculated from the date you first furnish labor or materials, not from the overall project commencement date.

Failing to Review the Notice of Commencement

Missing a required recipient listed in the Notice of Commencement can create compliance issues and potentially invalidate the notice.

Waiting Until Day 45 to Send the Notice

Even if technically timely, last-minute mailing increases the risk of delivery problems.

Best Practice

Serve the Notice to Owner by Day 40 whenever possible to provide a buffer for delivery delays.

Best Practices for Filing a Notice to Owner in Florida

1. Understand and calendar the 45-day deadline immediately.

2. Review the Notice of Commencement before preparing the NTO.

3. Include accurate project and owner information.

4. Use certified mail or another approved delivery method.

5. Retain copies of all notices and delivery confirmations.

6. Send the NTO as early as possible.

7. Follow Florida statutory formatting requirements.

8. Use a professional template to reduce errors.

9. Maintain communication with project stakeholders.

10. Consult a construction attorney when unusual situations arise.

Related Florida Lien Deadlines You Must Also Know

The Notice to Owner is only one part of Florida's lien process. Contractors should also monitor the following deadlines.

Claim of Lien

A Claim of Lien must be recorded within 90 days after the last furnishing of labor, services, or materials.

Service of the Recorded Lien

A copy of the recorded lien must be served on the owner within 15 days after recording.

Lien Enforcement Lawsuit

A lawsuit to enforce the lien generally must be filed within one year after recording the lien, although that period may be shortened to 60 days if a Notice of Contest of Lien is served.

Missing any of these deadlines can invalidate your lien rights even if your Notice to Owner was properly served.

Quick Reference Checklist

• Determine whether you are required to serve a Notice to Owner.

• Identify your first furnishing date.

• Calendar the 45-day deadline immediately.

• Aim to send the NTO by Day 40.

• Obtain and review the Notice of Commencement.

• Serve the NTO using an approved delivery method.

• Include complete and accurate project information.

• Retain proof of service and delivery.

• Monitor all subsequent lien deadlines.

Conclusion

The Florida Notice to Owner is a critical requirement for subcontractors, suppliers, and other parties seeking lien protection. The 45-day deadline is strictly enforced, and failure to comply can result in the permanent loss of lien rights.

By serving the NTO early, using the correct delivery method, and maintaining accurate records, construction professionals can significantly reduce payment risk and preserve their ability to enforce lien rights when necessary.
