If you bought a newly built home, you likely received some form of builder warranty at closing — but the coverage, duration, and process for making a claim vary enough between builders and states that it's worth actually reading your specific document rather than assuming a standard national protection applies.
The common industry structure: '1-2-10'
A widely used pattern in the new-home warranty industry, commonly called '1-2-10,' breaks coverage into three tiers with different durations. This structure comes from warranty-industry companies that underwrite these products for builders, not from a government requirement — it's a common convention, not a legal mandate.
| Tier | Typical duration | What it generally covers |
|---|---|---|
| Workmanship/materials | 1 year | Fit and finish issues — doors, trim, paint, drywall, and similar workmanship defects |
| Systems | 2 years | Plumbing, electrical, and HVAC/mechanical distribution systems |
| Major structural defects | 10 years | Foundation, framing, and other load-bearing structural elements |
This is not a government-mandated warranty in most states: Unlike some consumer protections that are set by law, most states do not require builders to provide a warranty at all, and where warranties are common practice, the specific terms are set by the builder or the third-party warranty company underwriting it — not by statute. Some states do have limited implied warranty protections through case law or specific statutes, but these are narrower and different from the 1-2-10 structure, so don't assume your state guarantees this exact coverage even if it's common in your area.
What tends to fall outside the coverage
Warranty documents commonly exclude normal wear and tear, damage from the homeowner's own neglect or improper maintenance, cosmetic issues after the initial workmanship period, and damage from events outside the builder's control (severe weather, for example). Appliances are frequently covered under their own separate manufacturer warranties rather than the builder's home warranty, since they're products the builder installed rather than built.
What to actually do with your warranty document
- Read the actual document rather than relying on what you were told verbally at closing — the specific covered items, exclusions, and claim process are all defined in writing.
- Note the exact start date for each tier, since it's typically tied to your closing date, and mark the tier-1 and tier-2 expiration dates on your maintenance calendar so you don't miss a claim window.
- Understand the claim process before you need it — most builder warranties require written notice within a specific timeframe after you discover an issue, not whenever it's convenient to report it.
- If something arises that seems like it should be covered, document it thoroughly (photos, dates, any related conversations) before contacting the builder or warranty company.
- Keep the warranty document somewhere you can actually find it years later, since structural coverage can run a full decade and you may not remember the specific terms by the time you need them.
Why this matters for your own maintenance planning
Understanding what your warranty does and doesn't cover changes how you should prioritize your own maintenance during the covered period — an issue with a covered system is worth reporting promptly while it's still under warranty, rather than waiting and paying out of pocket for something that should have been the builder's responsibility.
If you're buying a resale home rather than a new build, ask directly whether any portion of the original builder's structural warranty might still be active and transferable, since the 10-year structural tier in a 1-2-10 style warranty is long enough to still be running years after the original owner moved out. Warranty transferability terms vary by the specific warranty company and are worth confirming in writing during a resale transaction rather than assuming coverage automatically lapsed with the first owner.
It's also worth asking your builder directly, in writing, what process they use for warranty claims specifically — some builders handle claims in-house while others route everything through the third-party warranty company that underwrites the coverage. Knowing which applies to your home before you actually need to file a claim saves real time, since the correct first call differs depending on how your particular warranty is structured.
Also confirm whether routine maintenance tasks you perform yourself, such as caulking or gutter cleaning, are a condition of keeping certain warranty items valid, since some builder warranties include maintenance obligations for the homeowner and can deny a claim tied to neglecting them.
What does the '1-2-10' new home warranty structure actually cover?
It's a common industry pattern with three tiers: 1 year for workmanship and materials like doors, trim, paint, and drywall; 2 years for systems including plumbing, electrical, and HVAC; and 10 years for major structural defects like the foundation and load-bearing framing.
Is a new home warranty required by law?
In most states, no. Builders are generally not legally required to provide this kind of warranty, and where the 1-2-10 structure is common practice, the specific terms are set by the builder or the third-party warranty company underwriting it rather than by statute.
What's typically excluded from a new home warranty?
Common exclusions include normal wear and tear, damage from the homeowner's own neglect or improper maintenance, cosmetic issues after the initial workmanship period ends, and damage from events outside the builder's control such as severe weather. Appliances are usually covered separately under their own manufacturer warranties.
Can a new home warranty transfer if I buy a resale home?
Sometimes — the 10-year structural tier can still be active years after the original owner moved out, and transferability terms vary by the specific warranty company. Ask directly and get confirmation in writing during a resale transaction rather than assuming coverage lapsed with the first owner.
