Understanding Preliminary Notices in Florida
Florida uses a preliminary notice system. Here's what that means in plain English: when you start working on a construction project (or deliver your first batch of materials), you need to send a document called the “Notice to Owner” to certain people within 45 days.
Imagine you're an electrician hired to wire a new office building in Florida. Your first day on the job site is March 1st. Under Florida law, you need to send the Notice to Owner by 45 days later. This notice goes to the property owner, the general contractor. Send it on time to keep your lien rights active. This is the single most important compliance step on any Florida project.
Who Needs to Send a Preliminary Notice in Florida?
This applies to nearly everyone who works on a construction project and wants to protect their payment rights. That includes general contractors, subcontractors (electricians, plumbers, roofers, etc.), material suppliers (lumber, concrete, fixtures), equipment rental companies, laborers, architects and engineers, and surveyors. The specific rules — like who you need to notify and your deadline — depend on your role. Check the table below to see exactly what applies to you.
Why Preliminary Notices Matter
The Notice to Owner is what keeps your lien rights active in Florida. It's standard paperwork — sending it on time protects your payment on every project.
What If You Miss the Deadline?
Late Notice is Better Than No Notice
If you miss the 45-day deadline, don't give up. Florida allows late notices with partial protection. A late Notice to Owner covers your work from the 45 days BEFORE you sent the notice, plus everything after. You only lose protection for the earliest work. Send it as soon as you realize you missed the deadline.
Who Must Receive the Notice to Owner?
Who you need to notify depends on your role on the project. Here's a simple breakdown:
| If You Are A... | You Must Notify... |
|---|---|
| General Contractor | No notice typically required (direct contract with owner) |
| Subcontractor | Property Owner, General Contractor, owner designee |
| Material Supplier | Property Owner, General Contractor, owner designee |
| Laborer | Property Owner, General Contractor, owner designee |
| Equipment Rental Company | Property Owner, General Contractor, owner designee |
| Architect / Engineer / Surveyor | Property Owner, General Contractor, owner designee |
How to Deliver the Notice in Florida
Use one of the approved delivery methods below to make sure your notice is valid. Florida accepts these methods:
Certified Mail — You send via USPS and get a green receipt card proving the notice was delivered. This is the gold standard because it creates clear proof of delivery.
Personal Delivery — You (or someone you designate) hand-deliver the notice directly to the recipient. Make sure to get a signed acknowledgment as proof.
Statutory Notice Language
Florida law requires your Notice to Owner to include specific warning language. This isn't language you write yourself — it's exact wording specified by FL Stat. §§ 713.001 et seq.. Using the wrong language (or leaving it out) can invalidate your notice. LienGrid automatically includes the correct statutory language for Florida.

WARNING! FLORIDA'S CONSTRUCTION LIEN LAW ALLOWS SOME UNPAID CONTRACTORS, SUBCONTRACTORS, AND MATERIAL SUPPLIERS TO FILE LIENS AGAINST YOUR PROPERTY EVEN IF YOU HAVE MADE PAYMENT IN FULL. UNDER FLORIDA LAW, YOUR FAILURE TO MAKE SURE THAT WE ARE PAID MAY RESULT IN A LIEN AGAINST YOUR PROPERTY AND YOUR PAYING TWICE. TO AVOID A LIEN AND PAYING TWICE, YOU MUST OBTAIN A WRITTEN RELEASE FROM US EVERY TIME YOU PAY YOUR CONTRACTOR. Florida law prescribes the serving of this notice and restricts your r...
