Florida's Construction Lien Law includes several types of notices that serve different purposes at different stages of a construction project. Two of the most commonly confused are the Notice to Owner (NTO) and the Notice to Contractor. They sound similar, but they protect different parties, serve different functions, and are governed by different sections of the statute.
The Notice to Owner: protecting subcontractors and suppliers
The Notice to Owner is governed by Florida Statute 713.06. It is the notice that subcontractors, sub-subcontractors, and material suppliers must serve on the property owner to preserve their right to file a construction lien. If you do not have a direct contract with the property owner and you want to protect your lien rights, the NTO is your responsibility to file.
The NTO must be served within 45 days of first furnishing labor, services, or materials to the project. It goes to the property owner, the general contractor, and the surety (if applicable). Its purpose is to put the property owner on notice that you are contributing to the project and may have a claim against the property if you are not paid.
The Notice to Contractor: protecting the property owner
The Notice to Contractor is a different document entirely. It is governed by Florida Statute 713.132 and is initiated by the property owner, not by the subcontractor. When a property owner makes a payment to the general contractor, the owner can serve a Notice to Contractor demanding that the contractor provide a list of all subcontractors and suppliers who have served Notices to Owner on the project.
The purpose of this notice is to help the property owner understand their exposure. By knowing who has filed NTOs, the owner can make more informed decisions about payments and ensure that the general contractor is actually paying the subcontractors and suppliers working on the project.
Key differences at a glance
The Notice to Owner is filed by the subcontractor or supplier to protect their lien rights. The Notice to Contractor is initiated by the property owner to understand who has lien rights on their property. The NTO has a strict 45-day deadline from first furnishing. The Notice to Contractor can be served at various points during the project when the owner makes payments. The NTO is your responsibility as a subcontractor or supplier. The Notice to Contractor is the owner's tool for managing risk.
Why the confusion matters
The most dangerous misunderstanding is when a subcontractor assumes that because the property owner is somehow involved in the notice process, they do not need to file their own NTO. That is incorrect. The Notice to Contractor does not replace, substitute for, or eliminate the need for your Notice to Owner. These are two separate documents serving two separate purposes under two separate sections of the statute.
As a subcontractor or supplier, the only notice you need to worry about filing yourself is the Notice to Owner. It is your responsibility, it has a firm deadline, and failing to file it eliminates your lien rights on the project. Everything else in the lien law ecosystem is secondary to getting your NTO on file within 45 days.
Other notices in the Florida lien law process
For context, there are several other notices in Florida's Construction Lien Law. The Notice of Commencement is recorded by the property owner before construction begins. The Claim of Lien is the actual lien document filed after an NTO has been served and payment has not been received. The Notice of Contest of Lien is filed by the property owner to challenge a lien and shorten the enforcement deadline. Each plays a role, but for subcontractors and suppliers, the sequence that matters most starts with filing your Notice to Owner on time.
