California’s SB 800 Right-to-Repair statute gives homeowners a structured legal path to address construction defects in newly built homes — without immediately going to court. Signed into law in 2002, SB 800 establishes specific building standards, mandatory repair timelines, and a pre-litigation process that builders must follow before a homeowner can file a lawsuit.
For homeowners, landlords, and property managers dealing with defects in new construction, understanding this law determines whether you have a valid claim, how long you have to act, and what your builder is legally required to do.
This guide explains what SB 800 covers, who it applies to, how to file a claim, and what to expect once the process begins.
What Is California’s SB 800 Right-to-Repair Law?
California’s SB 800, formally known as the Right-to-Repair Act, is a state law that governs construction defect claims for newly built residential homes. It replaced the previous common law standard for most new home construction defect disputes and created a defined set of building performance standards that all builders must meet.
The law applies to new residential construction sold on or after January 1, 2003. It gives builders the right to inspect and repair defects before a homeowner can pursue litigation — but it also sets firm deadlines and quality standards that protect the homeowner throughout that process.
SB 800 was designed to reduce costly litigation by creating a structured resolution process. For homeowners, it provides clear legal standing and defined remedies. For builders, it provides an opportunity to correct defects before a lawsuit is filed.
SB 800 sits within a broader set of homeowner repair rights that govern how construction defects are handled across California — our complete guide to homeowner repair rights explains how state and federal protections work together to keep your property covered.
Key Definitions Under SB 800
Understanding SB 800 requires familiarity with a few core terms the statute uses consistently.
A construction defect under SB 800 is any failure of a home component to meet the performance standards defined in the statute — not simply any flaw or imperfection. A builder is defined broadly to include general contractors, subcontractors, material suppliers, and design professionals involved in the original construction. A claimant is the homeowner or subsequent purchaser asserting a defect claim. The notice and claim process is the mandatory pre-litigation procedure that must be completed before any lawsuit can be filed.
What SB 800 Covers: Defects, Standards, and Timelines
SB 800 establishes two categories of performance standards that builders must meet: functionality standards and workmanship standards. These standards define what counts as a defect under the law and determine whether a homeowner has a valid claim.
Understanding which defects qualify under SB 800 requires familiarity with California’s broader construction defect standards, which define the technical thresholds builders must meet across structural, mechanical, and finish categories.
Functionality Standards vs. Workmanship Standards
Functionality standards address the performance of major building systems. These include the foundation, framing, roof, plumbing, electrical systems, windows, doors, and HVAC components. A defect under a functionality standard means the system failed to perform as the statute requires — for example, a roof that allows water intrusion or a foundation that shows movement beyond permitted tolerances.
Workmanship standards address the quality of finish work and installation. These cover items such as paint, flooring, tile, drywall, and cabinetry. Workmanship defects are typically less severe but are still actionable under SB 800 if they fall below the statute’s defined quality threshold.
The distinction matters because different standards carry different statute of limitations periods, which affects how long a homeowner has to file a claim.
Statutory Repair Timelines Builders Must Follow
Once a homeowner submits a written notice of claim, SB 800 sets strict timelines the builder must follow. The builder has 14 days to acknowledge receipt of the notice. Within 30 days of acknowledgment, the builder must complete an inspection of the claimed defects. Following the inspection, the builder has 30 additional days to offer a repair, a cash settlement, or a combination of both.
If the builder fails to meet any of these deadlines, the homeowner may proceed directly to litigation without completing the full pre-litigation process.
Who SB 800 Applies To: Builders, Homeowners, and Buyers
SB 800 applies to the original purchaser of a newly constructed home and, in most cases, to subsequent purchasers as well. The law covers single-family homes, condominiums, and multi-unit residential buildings constructed and sold after January 1, 2003.
California’s SB 800 works alongside the state’s new home warranty protections, which set additional coverage periods for structural components, plumbing, and electrical systems in newly constructed homes.
Original Buyers vs. Subsequent Purchasers
The original buyer has the clearest standing under SB 800 because they entered into a direct purchase agreement with the builder. Subsequent purchasers — those who bought the home after the original sale — also have rights under the statute, but their claims are subject to the same statute of limitations periods that began running from the date of original construction or the date the defect was discovered.
This distinction is particularly important for landlords and property managers who acquire newly built properties through resale. The statute of limitations may have already been running before the property changed hands, which means acting quickly after discovering a defect is critical.
How to File a Claim Under SB 800
Filing a claim under SB 800 begins with a written notice sent directly to the builder. This notice must describe the defects in sufficient detail for the builder to identify and inspect them. Vague or incomplete notices can delay the process or give the builder grounds to dispute the claim’s validity.
Before submitting your SB 800 notice, it is essential to thoroughly document construction defects with photographs, written records, and professional assessments — our step-by-step guide walks through every method you need to build a strong claim.
The Pre-Litigation Notice and Inspection Process
The SB 800 pre-litigation process follows a defined sequence that both parties must complete before a lawsuit can be filed.
Step 1 — Written Notice: The homeowner sends a written notice of claim to the builder describing each defect. The notice must be sent to the builder’s last known address and should be sent via certified mail to create a documented record.
Step 2 — Builder Acknowledgment: The builder has 14 days to acknowledge receipt of the notice in writing.
Step 3 — Inspection: Within 30 days of acknowledgment, the builder must inspect the property and assess the claimed defects. The homeowner has the right to have a representative present during the inspection.
Step 4 — Builder’s Response: Within 30 days after the inspection, the builder must provide a written response offering to repair the defects, offering a cash settlement, or disputing the claim.
Step 5 — Homeowner’s Decision: The homeowner reviews the builder’s offer and either accepts it, rejects it, or requests further negotiation. If the parties cannot reach an agreement, the homeowner may proceed to litigation.
If the builder fails to respond at any stage within the required timeframe, the homeowner is released from the pre-litigation requirement and may file suit immediately.
SB 800 vs. Common Law Claims: What Homeowners Need to Know
Before SB 800, California homeowners pursued construction defect claims under common law theories including negligence, breach of contract, and strict liability. SB 800 did not eliminate common law claims entirely — but it significantly changed how and when they can be used.
For most new home construction defects covered by SB 800’s performance standards, the statute is now the exclusive remedy. This means a homeowner cannot bypass the SB 800 pre-litigation process and go directly to a common law lawsuit for defects that fall within the statute’s defined standards.
However, common law claims remain available for defects that SB 800 does not cover — such as defects that cause actual personal injury or property damage beyond the home itself. In those situations, a homeowner may pursue both an SB 800 claim and a parallel common law claim.
For homeowners weighing whether to pursue SB 800 or a common law claim, understanding the full scope of homeowner legal protections in California helps clarify which path offers the strongest remedy for your specific situation.
What Happens After a Builder Receives Your SB 800 Notice
Once the builder receives a valid SB 800 notice, the process moves into the inspection and response phase. The builder’s response options are defined by the statute and carry specific obligations depending on which option they choose.
Repair, Cash Settlement, or Dispute Resolution
Repair: If the builder offers to repair the defects, they must complete the repairs within a reasonable time and to a standard that meets SB 800’s performance requirements. The homeowner has the right to inspect the completed repairs and dispute their adequacy if the work does not meet the statutory standard.
Cash Settlement: The builder may offer a monetary settlement in lieu of repairs. The homeowner is not required to accept a cash offer and may reject it and proceed to litigation if the amount does not adequately address the defects.
Dispute: If the builder disputes the claim — asserting that no defect exists or that the defect does not fall within SB 800’s standards — the parties may enter mediation or proceed to litigation.
When a builder completes repairs under SB 800, working with qualified home repair services ensures the remediation meets the same statutory standards the original construction was required to follow.

Frequently Asked Questions
What types of defects does SB 800 cover?
SB 800 covers defects in major building systems such as foundations, roofing, plumbing, electrical, and HVAC, as well as workmanship defects in finishes like flooring, drywall, and paint. The defect must fall below the statute’s defined performance standards to qualify as a valid claim.
How long do I have to file a claim under SB 800?
The statute of limitations under SB 800 varies by defect type. Structural defects carry a 10-year period, while most other defects carry periods ranging from 1 to 4 years from the date of discovery or the close of escrow. Acting promptly after discovering a defect is essential to preserving your rights.
Does SB 800 apply to homes built before 2003?
No. SB 800 applies only to new residential construction sold on or after January 1, 2003. Homes built and sold before that date are governed by common law construction defect standards, not SB 800.
Can I sue my builder directly without going through the SB 800 process?
For defects covered by SB 800’s performance standards, you must complete the pre-litigation notice and inspection process before filing a lawsuit. Skipping this process can result in your case being dismissed. Exceptions apply when defects cause personal injury or damage beyond the home itself.
What if my builder ignores my SB 800 notice?
If the builder fails to acknowledge your notice within 14 days, fails to inspect within 30 days, or fails to respond within the required timeframe after inspection, you are released from the pre-litigation requirement and may proceed directly to litigation.
Does SB 800 protect subsequent buyers, not just the original purchaser?
Yes. Subsequent purchasers of a newly built home retain rights under SB 800, subject to the same statute of limitations periods that began running from the original construction date or the date the defect was discovered. Buyers of resale new construction should assess any running deadlines immediately.
What is the difference between SB 800 and a builder’s express warranty?
An express warranty is a contractual promise made by the builder at the time of sale, covering specific components for defined periods. SB 800 is a statutory right that exists independently of any contract — it applies even if the builder’s express warranty has expired, provided the applicable statute of limitations has not run.
