Florida’s New Mandatory Builder Warranty: What Developers Need to Know

Effective July 1, 2025, a new provision of Florida law, Section 553.837, Florida Statutes, establishes a mandatory builder warranty for qualifying newly constructed homes. This statute imposes minimum warranty obligations on builders of single-family homes, duplexes, triplexes, and quadruplexes. For residential developers and homebuilders, understanding the scope and practical implications of this law is essential to managing risk.

What the New Warranty Covers

Section 553.837 requires a builder to warrant a newly constructed home against all construction defects of equipment, material, or workmanship furnished by the builder or any subcontractor or supplier that result in a “material violation” of the Florida Building Code. The term “material violation” carries the same meaning as in Section 553.84, Florida Statutes, linking the warranty standard to the existing statutory framework governing building code violations.

The warranty lasts for one year after the earlier of (1) the date of original conveyance of title to the initial owner, or (2) the date of initial occupancy of the residence. This creates a bright-line deadline that builders must track carefully from the point of sale or first use.

Importantly, the statute defines “newly constructed home” to include residential real property and certain manufactured, modular, or factory-built buildings that are single-family dwellings, duplexes, triplexes, or quadruplexes that have not been previously occupied. Defects involving appliances or equipment covered by a manufacturer’s warranty are excluded from the scope of the statutory builder warranty.

What Is Excluded

The statute expressly carves out several categories from the required warranty coverage:

•       Normal wear and tear.

•       Normal house settling within generally acceptable trade practices.

•       Defects caused by work or materials supplied incident to construction, modification, or repair performed by the initial purchaser, a subsequent purchaser, or anyone acting on their behalf (other than the builder or its employees, agents, or contractors).

•       Loss or damage caused by the initial purchaser, a subsequent purchaser, a third party, or an act of God outside the builder’s control, such as a natural disaster or lightning-caused fire.

These exclusions provide builders with clear defenses to warranty claims arising from events outside the builder’s responsibility. However, the burden will be on the builder to demonstrate that an exclusion applies, which makes documentation at the point of sale and during the warranty period critical.

Builder’s Remedy Obligation

When a covered defect exists, the builder must remedy the defect at the builder’s expense and restore any work damaged in fulfilling the warranty. The statute also provides that a builder may purchase a warranty from a home warranty association licensed under Chapter 634, Florida Statutes, to cover the required warranties. This gives builders flexibility to manage risk through insurance products rather than self-insuring all warranty obligations.

Why Transferability Matters for Developers and Purchasers

A significant feature of Section 553.837 is that the builder must comply with the one-year warranty requirement even if the home is sold or transferred and is no longer owned by the initial owner. This means the statutory warranty automatically follows the property during the one-year period, regardless of changes in ownership. For developers marketing homes to investors or in markets with high early turnover, this is an important consideration—warranty obligations cannot be extinguished simply because the initial purchaser flips the property.

How Express Warranties Can Supersede the Statutory Default

If the builder's express written warranty offers the same or greater scope, coverage, and duration, and it automatically transfers to a new owner during at least the initial one-year period, then the new statutory warranty will not apply. If a builder’s express written warranty extends beyond the one-year statutory requirement, it must clearly state that it exceeds the statutory minimum, specify the length of the warranty, and disclose whether the warranty is transferable beyond the one-year statutory period along with any applicable transfer terms.

This framework gives builders an incentive to provide well-drafted express warranties that can serve as the governing warranty document, rather than relying on the statutory default.

Enforcement and Limitations

Enforcement of Section 553.837 is limited to a private civil cause of action by a purchaser against a builder that fails to comply. The statute does not create an administrative enforcement mechanism or regulatory penalty. Notably, the statute expressly provides that it does not extend the statute of repose beyond otherwise applicable law, meaning the existing limitations periods under Florida’s construction statute of repose remain in effect.

Applicability and Interaction with Other Warranty Regimes

It is important to understand that Section 553.837 does not apply to all new construction in Florida. Its scope is limited to a defined “newly constructed home”—single-family dwellings, duplexes, triplexes, and quadruplexes (including certain manufactured, modular, and factory-built buildings) that have not been previously occupied. The statute does not, by its terms, extend to traditional condominium projects, larger multifamily developments, or renovations of exiting single-family homes.

For condominium projects, Chapter 718, Florida Statutes, provides a separate warranty regime. Section 718.203 establishes implied warranties for condominium developers, contractors, subcontractors, and suppliers, covering the roof, structural components, mechanical and plumbing elements, and other building elements for specified periods. Developers of residential projects should carefully assess how Section 553.837 interacts with other Florida statutory warranty regimes, including condominium warranties under Chapter 718, to determine which obligations apply to a given project type—particularly for mixed residential, townhome, and small multifamily projects that may fall near the boundary of the statute’s definitions.

Conclusion

Section 553.837 represents a meaningful shift in Florida’s residential construction landscape by codifying a minimum warranty standard that applies regardless of whether a builder provides a separate written warranty. For developers and builders of qualifying newly constructed homes, the statute creates both obligations and opportunities. The obligations require updating contracts, processes, and risk management strategies. The opportunities lie in using well-drafted express warranties to control the scope and terms of warranty coverage while exceeding the statutory minimum.

Builders and developers should work with experienced real estate and construction counsel to review their warranty programs, update form documents, and implement compliance systems that align with the new statutory requirements. Early attention to these details will help avoid disputes and position builders to defend against unwarranted claims when they arise.
