Before a homeowner or HOA can file a construction defect lawsuit in California for homes sold on or after January 1, 2003, the law requires a mandatory prelitigation process. This process, established by SB 800 — the Right to Repair Act (Civil Code Sections 895-945.5) — begins with a formal written notice to the builder and proceeds through a series of defined steps designed to give the builder an opportunity to inspect the property and offer repairs. Skipping this process can result in the dismissal of a lawsuit, making it essential that claimants understand and follow each step correctly.

The Purpose of the Prelitigation Process

The California Legislature enacted the SB 800 prelitigation process to reduce construction defect litigation by giving builders the opportunity to resolve claims before they reach the courthouse. The theory is straightforward: if a builder can inspect the defects and make repairs at a reasonable cost, both parties avoid the expense and delay of litigation. For more, see Understanding California's SB 800 Right to Repair Act.

In practice, the prelitigation process serves multiple purposes. It creates a documented record of the claimed defects. It establishes a timeline of the builder's response (or failure to respond). And it provides evidence that becomes valuable in any subsequent litigation — particularly when a builder ignores the notice, conducts a superficial inspection, or offers repairs that fail to address the underlying problems.

Step-by-Step: The SB 800 Prelitigation Timeline

Step 1: Written Notice to the Builder

The process begins when the homeowner or HOA sends a written notice to the builder describing the claimed construction defects in reasonable detail. Under Civil Code Section 910, the notice must include a description of the defects sufficient to allow the builder to identify the nature and location of the claimed problems.

The notice should be sent by certified mail or another method that provides proof of delivery. While the statute does not prescribe a specific format, the notice should be detailed enough to identify each category of defect — water intrusion through the building envelope, foundation cracking, plumbing leaks, and so on — without necessarily requiring a full forensic report at this stage.

Step 2: Builder's Acknowledgment (14 Days)

Within 14 days of receiving the notice, the builder must acknowledge receipt in writing. The acknowledgment should describe the builder's election to inspect the property. If the builder fails to acknowledge the notice within this timeframe, the claimant may proceed to file a lawsuit without completing the remaining prelitigation steps.

Step 3: Builder's Inspection

If the builder elects to inspect, the inspection must be completed within a timeframe established by the statute. The builder has the right to conduct a reasonable inspection, which may include visual observation, non-destructive testing (moisture meters, infrared scans), and — with proper notice and coordination — destructive testing to examine concealed conditions.

The claimant should be present during the inspection or have a representative observe the process. Documenting the scope and findings of the builder's inspection is important, particularly if the builder's assessment later conflicts with the claimant's expert findings.

Step 4: Builder's Offer of Repair (30 Days After Inspection)

Within 30 days after completing the inspection, the builder must provide a written offer to repair the claimed defects. Under Civil Code Section 912, the offer must describe the repairs the builder proposes to make, the timeline for completing them, and any monetary compensation offered.

The builder may also offer a cash payment in lieu of repairs, or a combination of repairs and payment. If the builder fails to make any offer within the 30-day period, the claimant is released from the prelitigation process and may file suit.

Step 5: Claimant's Response

The claimant has the right to accept, reject, or negotiate the builder's offer. If the offer is accepted, the builder proceeds with the agreed-upon repairs. If the offer is rejected — either because the proposed repairs are inadequate or because the claimant disputes the builder's assessment of the defects — the claimant is free to file a lawsuit.

There is no requirement that the claimant accept any offer. The decision to accept or reject should be based on a careful evaluation of whether the proposed repairs will actually resolve the defective conditions, not merely address cosmetic symptoms.

What Happens When the Builder Does Not Respond

Builders who fail to respond to a prelitigation notice within the statutory timeframes effectively waive their right to the prelitigation process. Under Civil Code Section 920, if the builder fails to acknowledge the notice within 14 days, or fails to inspect or make an offer within the applicable timeframes, the claimant's obligation to continue the prelitigation process is extinguished, and the claimant may proceed directly to litigation.

This provision is significant because some builders — particularly those that have dissolved, changed names, or are in financial distress — may simply not respond. The statute anticipates this possibility and does not allow a builder's non-participation to indefinitely delay the claimant's access to the courts.

Practical Considerations

Be thorough in the initial notice. While the statute requires only a description of the defects in "reasonable detail," providing a comprehensive list of defects at the outset strengthens the claim. Defects that are not included in the notice may be challenged later as outside the scope of the prelitigation process.

Do not allow the builder to control the narrative. The builder's inspection is conducted with the builder's interests in mind. Claimants should conduct their own independent forensic investigation before or in parallel with the builder's inspection. For more, see How to Choose a Forensic Engineering Expert for California.

Document everything. Every communication, inspection date, offer, and response should be documented in writing. The prelitigation record becomes evidence in any subsequent litigation, and a well-documented record strengthens the claimant's position.

The prelitigation process is a procedural prerequisite, not a barrier. When followed correctly, it provides homeowners and associations with a structured path toward resolution — and when the builder fails to participate meaningfully, it creates a clear record that supports the case going forward.
