Dear Sir or Madam:
This firm represents [OWNER NAME] ("Owner" or "Claimant") regarding construction defects at the above-referenced property. This letter constitutes formal notice of construction defects pursuant to California Civil Code Sections 910-938 (commonly known as the SB 800 Right to Repair Act), and serves as the required pre-litigation notice providing you with the statutory opportunity to inspect, offer to repair, and/or settle this claim before litigation is commenced.
THIS IS A STATUTORY NOTICE REQUIRED UNDER CALIFORNIA LAW. YOUR TIMELY RESPONSE IS REQUIRED WITHIN THE TIMEFRAMES SET FORTH IN CIVIL CODE SECTION 913.
I. CALIFORNIA-SPECIFIC LEGAL FRAMEWORK
A. SB 800 Right to Repair Act (Civil Code Sections 895-945.5)
This notice is provided pursuant to California's comprehensive Right to Repair Act, which establishes:
Functionality Standards (Civ. Code Section 896):
The Act defines specific standards for various building components that builders must meet, including:
- Section 896(a): Water intrusion standards for roofs, windows, doors, decks, etc.
- Section 896(b): Structural standards for foundations, load-bearing components
- Section 896(c): Soil standards requiring proper preparation and drainage
- Section 896(d): Fire protection standards
- Section 896(e): Plumbing and sewer standards
- Section 896(f): Electrical system standards
- Section 896(g): Other standards including noise, irrigation, landscaping
Pre-Litigation Procedures (Civ. Code Sections 910-938):
- Section 910: Claimant must provide written notice of claim
- Section 913: Builder must acknowledge receipt in writing within 14 days after receipt of the notice
- Section 916: If the builder elects to inspect, it must complete the initial inspection and testing within 14 days after acknowledgment of receipt of the claim; a second inspection (if reasonably necessary, specified in writing within 3 days of the first) must be completed within 40 days of the initial inspection
- Section 917: Builder may offer in writing to repair within 30 days after the initial (or second) inspection
- Section 918: Homeowner has 30 days after receipt of the repair offer to authorize the builder (or to request up to three alternative contractors)
- Section 921: If resolution is by repair, repairs commence within 14 days of acceptance and every effort shall be made to complete them within 120 days (Section 921(b))
- Sections 919 & 928: The repair offer must be accompanied by an offer to mediate (Section 919); if the builder completed a repair and there was no prior mediation, the homeowner must request mediation in writing before filing (Section 928). Mediation occurs within 15 days of the request (four-hour session)
B. Applicable Statutes of Limitation Under SB 800
Most SB 800 standards carry the default 10-year outer limit measured from substantial completion (Civ. Code Section 941(a)); a handful of components in Sections 896(e)-(g) carry their own shorter periods running from close of escrow:
| Defect Category | Limitations Period | Authority |
|---|---|---|
| Water/moisture intrusion (windows, roofs, stucco, decks) | 10 years (default) | Civ. Code Section 896(a); Section 941 |
| Structural defects | 10 years (default) | Civ. Code Section 896(b); Section 941 |
| Soil-related defects | 10 years (default) | Civ. Code Section 896(c); Section 941 |
| Fire protection | 10 years (default) | Civ. Code Section 896(d); Section 941 |
| Plumbing/sewer | 4 years from close of escrow | Civ. Code Section 896(e) |
| Electrical | 4 years from close of escrow | Civ. Code Section 896(f) |
| Exterior pathways/driveways/hardscape | 4 years from close of escrow | Civ. Code Section 896(g)(1) |
| Other components (noise 1 yr; irrigation 1 yr; untreated wood posts 2 yr; landscaping/dryer ducts 2 yr; steel fences 4 yr; paint/stains 5 yr) | 1-5 years (component-specific) | Civ. Code Section 896(g) |
C. Statute of Repose / Outer Limit
For claims under the Right to Repair Act, the Act's own limitations provision, Civil Code Section 941(a), bars any action brought more than ten (10) years after substantial completion of the improvement (but not later than the date of recordation of a valid notice of completion). Section 941(d) expressly provides that Code of Civil Procedure Sections 337.15 and 337.1 do NOT apply to actions under the Act.
For common-law latent-defect claims outside the Act, Cal. Code Civ. Proc. Section 337.15 establishes a ten (10) year statute of repose for latent construction defects, running from substantial completion.
D. Alternative Common Law Claims
Exclusivity note: For new residential construction covered by the Act, the California Supreme Court held in McMillin Albany LLC v. Superior Court (2018) 4 Cal.5th 241 that the Right to Repair Act is the exclusive remedy and supplants common-law negligence and strict-liability claims for construction defects, whether or not the defect has caused property damage (disapproving Liberty Mutual Ins. Co. v. Brookfield Crystal Cove LLC (2013) 219 Cal.App.4th 98). Common-law theories below are therefore pleaded principally where SB 800 does not apply (e.g., pre-2003 construction, commercial property, condominium conversions) or as otherwise permitted:
- Breach of Contract: 4 years (CCP Section 337)
- Negligence: 3 years from discovery (CCP Section 338)
- Strict Liability: Where applicable and not supplanted by the Act (see McMillin)
- Breach of Express Warranty: Per warranty terms
- Implied Warranty of Habitability: Pollard v. Saxe & Yolles Dev. Co. (1974) 12 Cal.3d 374
E. Contractor Licensing (CSLB)
Under Bus. & Prof. Code Section 7000 et seq., contractors must be licensed by the Contractors State License Board. Unlicensed contractors:
- Cannot maintain actions for compensation (Bus. & Prof. Code Section 7031)
- Are subject to criminal penalties
- May be required to disgorge all compensation received

Spoliation Warning: California does not recognize an independent tort cause of action for the intentional first-party spoliation of evidence (Cedars-Sinai Med. Ctr. v. Superior Court (1998) 18 Cal.4th 1), but the intentional or negligent destruction of relevant evidence carries serious consequences, including an adverse evidentiary inference for willful suppression of evidence (Evid. Code Section 413) and the full range of discovery sanctions — monetary, issue, evidentiary, and terminating (Code Civ. Proc. Section 2023.030).

Common California Defects:
- Stucco and EIFS failures

Class Action Considerations:
- Multiple unit developments often warrant class or representative actions

Expert Requirements:
- CCP Section 411.35 requires certificate of merit for design professional claims
- Complex cases typically require multiple experts (water, structural, soils, etc.)

About This Template
A demand letter is a formal written request to fix a problem or pay what is owed, sent before anyone files a lawsuit. It gives the other side a real chance to settle, creates a record of your attempt to resolve things, and in many cases (unpaid debts, insurance claims, broken contracts) starts a legally required response window. A well-written demand letter lays out what happened, what you want, and a deadline to act, which is often enough to get results without ever going to court.
Important Notice
This template is provided for informational purposes. It is not legal advice. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.
