The longest tier of a new-home warranty covers major structural elements, often up to ten years. This guide explains how that coverage typically works in California and what to verify.
California new homes commonly carry a long-tier structural warranty up to ten years for major structural elements, alongside statutory defect rights under the Right to Repair Act (SB 800). Coverage definitions, exclusions, and the claims process vary by builder, so read the specific written warranty and confirm terms before closing.

Where the 10-year tier fits
Most builder warranties are tiered: short fit-and-finish coverage, multi-year systems coverage, and the longest tier for major structural elements (commonly up to ten years), such as load-bearing components. The exact list of covered elements and exclusions is defined in the written warranty.
Warranty versus statutory rights
The builder's written warranty operates alongside California's Right to Repair Act, commonly referenced as SB 800, which sets standards and a process for many residential construction defects with category-specific timeframes. These are legal matters; consult a qualified attorney for advice on your situation.
What to confirm
- The exact structural elements covered and the duration.
- Exclusions and maintenance obligations that can void coverage.
- The claims and notice process and required timeframes.
- Whether the warranty is builder-backed or third-party administered.
Protect your coverage
Document the home's condition at the final walk-through, report issues in writing within required windows, perform required maintenance, and keep records. Good documentation makes a structural claim far easier if one ever arises.

Frequently Asked Questions
How long is the structural warranty on a California new home?
The major-structural tier is commonly up to ten years, while fit-and-finish and systems tiers are shorter. Durations and covered elements vary by builder; read your specific written warranty.
Is the 10-year warranty the same as SB 800?
No. The builder's written warranty is contractual; SB 800 (the Right to Repair Act) is California's statutory framework for construction defects. They operate alongside each other. Consult an attorney for legal advice.
What can void structural coverage?
Failure to perform required maintenance, unapproved alterations, or not reporting issues within required windows can affect coverage. Read the warranty's exclusions and obligations carefully.
What should I do if I suspect a structural defect?
Report it in writing within the applicable window, keep records, and follow the claims process. For significant defects or disputes, consult a qualified construction-defect attorney.
What about interest rates and builder buydowns?
As a general 2026 reference, conventional 30-year rates have run roughly in the 6.5%-7.0% range, and builders sometimes offer rate buydowns that can reach into the high 4s on specific quick-move-in homes through their preferred lender. These offers change frequently and have conditions; verify current terms with the builder and compare against an outside lender.
Are the prices and phases on this page current?
No. This page is general guidance only and intentionally avoids quoting prices, phase availability, floor-plan sizes, completion dates, or incentive specifics, because they change constantly. Confirm all current details directly with the builder.
