📋 What Are Construction Defects?

Construction defects are deficiencies in the design, materials, or workmanship of a building that cause damage, reduce its value, or make it unsafe. California law provides extensive protections for propietarios through the Contratistas State License Board (CSLB), the contratista's license bond, and the SB 800 Right to Reparación Act for new residential construction.

California's Construction Defecto Framework

California provides multiple overlapping protections for propietarios dealing with construction defects:

📚 CSLB Contratistas State License Law (B&P Code 7000+)

California's comprehensive contratista licensing law requires all contratistas performing work over $500 to be licensed. Key provisions include:

  • B&P Code 7109: Departure from accepted trade standards or negligent construction is grounds for discipline
  • B&P Code 7110: Material deviation from plans without consent is a violación
  • B&P Code 7119: Failure to prosecute work diligently is grounds for discipline
  • B&P Code 7159: Contract requirements including scope, timeline, and payment terms

🏗 SB 800 Right to Reparación Act (código civil 895-945.5)

SB 800 (also known as the Right to Reparación Act) applies to new residential construction sold after January 1, 2003. It establishes specific construction standards and a mandatory pre-litigio reparación process:

  • Detailed standards for each building component (código civil 896-897)
  • Mandatory notice and reparación opportunity before filing suit
  • Specific timelines for builder response (código civil 910-938)
  • Statutes of limitation specific to each defecto type (código civil 941)

🔒 Contratista's License Bond (B&P Code 7071.5-7071.11)

Every licensed California contratista must maintain a $25,000 contratista's license bond. This bond protects propietarios:

  • Minimum bond is $25,000 (some specialty licenses require more)
  • Claims can be filed directly with the bonding company
  • Bond claims are separate from CSLB demandas and lawsuits
  • 2-year deadline from violación or 1 año(s) desde completion, whichever is later

🔗 Mechanic's Lien Protections (código civil 8000-8848)

Understanding mechanic's liens is crucial when dealing with construction defects, as unpaid subcontratistas may file liens against your property:

  • Subcontratistas must provide preliminary 20-day notices (código civil 8200)
  • You can demand lien releases before payment (código civil 8132-8138)
  • Joint check provisions protect you from paying twice
  • You can bond around filed liens (código civil 8424)

⚠ SB 800 vs. Common Law Claims

The type of reclamación you have depends on your property:

  • New residential construction (sold after 1/1/2003): SB 800 applies with mandatory pre-litigio reparación process
  • Remodel/renovation work: Traditional incumplimiento de contrato and negligencia claims apply
  • Commercial construction: SB 800 does not apply; common law claims only
  • Multi-unit residential: HOAs may pursue SB 800 claims on behalf of owners
