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

6 If accepted, repairs commence within 14 days; every effort to complete within 120 days of commencement Civ. Code Section 921(a)-(b)

B. Your Obligations Upon Receipt

Upon receipt of this notice, you are required to:

  1. Acknowledge Receipt: Provide written acknowledgment within 14 days after receipt of this notice (Civ. Code Section 913)
  2. Inspect (if elected): If you elect to inspect, complete the initial inspection and testing within 14 days of your acknowledgment (Civ. Code Section 916(a)); any second inspection must be completed within 40 days of the first (Civ. Code Section 916(c))
  3. Provide Written Offer: Offer to repair (accompanied by an offer to mediate) or otherwise compensate under Section 944 within 30 days after the inspection (Civ. Code Sections 917, 919)
  4. Note: Failure to acknowledge, elect, inspect, or offer within these deadlines releases the claimant from the prelitigation requirements and permits immediate filing of an action (Civ. Code Sections 915, 916(d), 920)

C. Inspection Procedures

If you elect to inspect pursuant to Civil Code Section 916:

  • Provide written notice of inspection dates
  • Inspections must be at mutually convenient times
  • You may employ qualified consultants and experts
  • Destructive testing requires advance written approval
  • You must repair damage caused by testing

D. Document Exchange

Pursuant to Civil Code Section 912, we request the following documents:

  • All maintenance and service records for the property
  • All claims reported and repairs made
  • All warranty information provided to original purchaser
  • Enhanced Protection Agreement (if any)

VII. PRESERVATION OF EVIDENCE

You are hereby directed to preserve all documents and materials, including:

  • All construction contracts and subcontracts
  • Plans, specifications, and drawings (including as-builts)
  • Building permits and inspection records

  • Daily construction logs and progress reports
  • Quality control and inspection reports

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).


VIII. SETTLEMENT DEMAND

To resolve this matter without litigation, we demand:

  1. Complete repair of all identified defects per Civ. Code Section 921

Mediation is a four-hour session occurring within 15 days of the request. We propose:

  • Mediator: [NAME] or mutually agreed mediator from [MEDIATION SERVICE]
  • Location: [CITY], California
  • Timing: Within 60 days of impasse

X. CONCLUSION

CALIFORNIA-SPECIFIC PRACTICE NOTES

SB 800 Applicability (Civ. Code Section 895):

  • Covers single-family homes, condos, townhouses, and multi-family (4 units or less)
  • Does NOT apply to commercial construction or conversions
  • Does NOT apply to owner-builder sales

Enhanced Protection Agreements (Civ. Code Section 901):

  • A builder may (but need not) offer greater protection or longer time periods than Chapter 2 (Section 896) by express contract; it may not lower the Section 896 protections. Such a contract is an "enhanced protection agreement."
  • If provided, EPA terms may govern in addition to the statutory minimums
  • Request copy of EPA if unknown (builder document duties are in Civ. Code Section 912)

CSLB Licensing:

  • Verify license at www.cslb.ca.gov
  • Unlicensed contractors cannot recover compensation
  • CSLB complaints may result in disciplinary action and restitution

Common California Defects:

  • Stucco and EIFS failures
  • Window/sliding door water intrusion
  • Deck and balcony waterproofing
  • Hillside foundation issues
  • Fire resistive construction defects (especially in WUI areas)

Class Action Considerations:

  • Multiple unit developments often warrant class or representative actions
  • HOA may have standing for common area defects
  • Davis-Stirling Act governs HOA claims

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.
