New Home Warranty Act: Coverage, Deadlines, and Damages

The Louisiana New Home Warranty Act gives every buyer of a newly built home three automatic warranties from the builder: one year against general workmanship defects, two years on major home systems, and five years against major structural defects. The Act is codified at La. R.S. 9:3141 through 9:3150, and it applies to every new home in the state whether or not the local jurisdiction enforces a building code.¹ To use those warranties you have to follow the Act’s notice and timing rules exactly, because the statute is also the only legal path for construction-defect claims between a builder and owner.

What the Three Warranties Cover

The length of coverage depends on the severity of the defect. All three clocks start on the same day — the warranty commencement date, discussed below.

One year, general defects. The builder warrants the home will be free from any defect caused by failure to meet building standards or by poor workmanship and materials. Cracked drywall, bad trim work, improperly installed flooring, and paint failures sit in this tier.²
Two years, major home systems. Plumbing, electrical, heating, cooling, and ventilation systems are warranted for two years. Appliances and fixtures connected to those systems are not; only the systems themselves.²
Five years, major structural defects. This longest tier covers damage to load-bearing components that makes the home unsafe, unsanitary, or unlivable. The statute lists foundation systems, footings, beams, girders, lintels, columns, walls and partitions, floor systems, and roof framing systems.³

The five-year warranty has a demanding threshold. The damage must actually affect the load-bearing function of the component to the point that the home becomes unsafe, unsanitary, or unlivable. A cosmetic crack in a foundation wall that doesn’t compromise structural integrity would not qualify.³

The term “builder” is defined broadly. Any person, corporation, partnership, LLC, or joint venture that constructs a new home qualifies, even if the builder initially lived in the home before selling it. It does not matter whether you also bought the land from the builder; constructing the home is enough to trigger the warranty obligations.³

When the Warranty Clock Starts

The warranty commencement date is whichever happens first: the date you receive legal title to the home, or the date someone first moves in.³ If you occupy a home before closing, your clock starts on the move-in date, not the closing date. Keep records of both dates. A builder who later argues your warranty expired before you filed will often reach for whichever date helps the defense.

What the Warranty Does Not Cover

The exclusion list in the statute is long, and some of these catch homeowners off guard:

Anything outside the home itself. Fences, landscaping, driveways, walkways, and off-site improvements are excluded entirely.²
Appliances, fixtures, and equipment. Your dishwasher, water heater, and light fixtures fall under their manufacturers’ warranties. The two-year systems warranty covers the plumbing and electrical lines in the walls, not the devices plugged into them.
Damage caused by the homeowner. Negligent maintenance, failure to keep adequate ventilation or drainage, unauthorized modifications, and changes to the grading around the home all void coverage for any resulting damage.
Natural disasters and external events. Floods, hurricanes, earthquakes, hail, lightning, mudslides, vehicles, aircraft, and civil disturbances are all excluded.
Normal wear and tear, and insect damage such as termites.
Losses that arise while the home is being used for nonresidential purposes.²
Work or materials supplied by someone other than the builder or the builder’s subcontractors. If you hire your own electrician to add a circuit and that work causes a problem, the builder owes you nothing for it.
Damage you failed to minimize in a timely way. Notice a leak, let it run for weeks, and the extra water damage from your delay sits outside the warranty.²

How to Notify the Builder of a Defect

Before you fix anything yourself or file suit, you must send the builder written notice describing every defect you want repaired. The notice must go by registered or certified mail, and it must be sent within one year after you first learn of the defect.⁴

That one-year-from-knowledge deadline sits on top of the warranty periods themselves. You could spot a plumbing defect 18 months after the warranty commencement date and still be within the two-year systems warranty, but if you wait 13 months after noticing the leak to mail your notice, the builder can deny the claim.

The notice must give the builder “a reasonable opportunity” to inspect and repair. The statute sets no specific number of days. What counts as reasonable depends on the defect and the scope of the repair, but you cannot send a letter on Monday and file suit on Tuesday. Allow time for the builder to schedule an inspection and arrange the work.

Do not make repairs yourself before sending notice. The statute says notice must come “before undertaking any repair.” Hire your own contractor to fix the problem first and the builder can argue you forfeited the warranty claim by denying the opportunity to inspect and repair.⁴

List every issue in your notice, not just the worst one. The statute requires you to advise the builder “of all defects.” If you leave a defect out and later try to add it to a lawsuit, the builder may argue that defect was never properly noticed. A solid notice describes each problem, says when you first observed it, and attaches photographs documenting the condition. Mail it to the builder’s registered agent — you can find the correct address on the Louisiana Secretary of State’s commercial database.⁵

The Hard Deadline to File Suit

Louisiana uses a peremptive period for these claims, which is an absolute deadline. After it passes, your right to sue ceases to exist, regardless of the circumstances. The period expires thirty days after the end of the applicable warranty period.⁶

In practice: if your warranty commencement date was January 1, 2024, the one-year warranty runs through January 1, 2025, and you have until January 31, 2025 to file suit on a general-defects claim. After that, the claim is gone. Add thirty days to the end of each of the three warranty periods for the equivalent cutoff on systems and structural claims.

You also need to have sent your written notice within one year of discovering the defect, and to have given the builder a reasonable opportunity to respond, all before that thirty-day window closes. The moment you spot a defect, the clock is already running on more than one deadline. Delay rarely helps.

What You Can Recover

If a builder fails to honor the warranty after proper notice, you can sue for actual damages, attorney fees, and court costs. Damages are measured by the reasonable cost to repair or replace the defective item, with two caps: damages for a single defect cannot exceed the reasonable cost to fix that defect, and total damages across all defects in the home cannot exceed the home’s original purchase price.⁷

The attorney-fee provision matters. In many lawsuits each side pays its own lawyer regardless of outcome. Under this Act, a homeowner who proves the builder violated the warranty can recover legal fees on top of repair costs.

The parties can agree to arbitrate warranty disputes rather than go to court. Any such arbitration must comply with Louisiana’s general arbitration statute at La. R.S. 9:4201 and following.⁷ Many builder purchase agreements include an arbitration clause, so read yours before assuming court is an option.

A separate protection worth asking about at closing: a builder may insure its warranty obligations through an insurance company authorized to do business in Louisiana.⁸ If the builder has warranty insurance and later goes out of business, you may be able to claim against the insurer.

Buying a Home Already Under Warranty

If you buy a home that is still within its warranty periods, the builder’s warranty transfers to you automatically and at no charge. Any warranty insurance the builder purchased transfers the same way.⁹ You do not need to file paperwork or register with the builder. The Act’s definition of “owner” also sweeps in heirs, assignees, and invited occupants.³

The key question for a subsequent buyer is when the warranty commencement date fell. If the original buyer closed three years before you did, the one-year and two-year warranties have already expired. You’d still have roughly two years left on the five-year structural warranty, but a thorough inspection before closing matters because systems and workmanship issues are no longer the builder’s problem.

The Act Is Your Only Path

The New Home Warranty Act is the exclusive remedy for construction-defect claims between a builder and an owner in Louisiana. No other warranty law or redhibition claim applies to new-home construction. You cannot sidestep the Act’s procedures by filing a general negligence lawsuit or invoking Louisiana’s broader rules on defective products. That cuts both ways. The Act gives you a clear set of rights and a defined process, and it leaves no fallback theory if you miss a deadline or skip the notice requirement.¹
