California's housing stock spans everything from 1900s craftsman bungalows to mid-century tract homes to modern construction — and each era brings its own inspection concerns. Add in regional climate variation (wet winters in the north, extreme heat inland, marine layer and salt air along the coast), and you get a state where inspection findings are shaped heavily by both age and geography.

A few factors are uniquely California. Seismic retrofitting requirements — particularly cripple wall bracing and anchor bolts — appear on many inspections for pre-1980 homes. HVAC systems vary dramatically: in coastal areas, air conditioning may be absent entirely; in the Central Valley and Southern California inland regions, aging AC units are a primary concern. Fire-resistant roofing and ember-resistant vents have become increasingly relevant as defensible space requirements expand.

California has strong seller disclosure laws. The Transfer Disclosure Statement (TDS) requires sellers to document known defects, and many jurisdictions require additional local disclosures. Still, a thorough independent inspection remains essential — disclosures reflect what sellers know, not what a qualified inspector may find.

Common California Considerations

  • Cripple wall and foundation anchor bolt deficiencies in pre-1980 homes
  • Galvanized or cast-iron plumbing in older homes (1940s–1970s)
  • Deferred maintenance on aging AC systems in inland and Southern California
  • Stucco cracking and water intrusion in coastal areas
  • Grading and drainage issues due to clay-heavy soils and seasonal dry-to-wet cycles

Local Requirements: California requires seller disclosure via Transfer Disclosure Statement (TDS). Local jurisdictions may require additional point-of-sale inspections (roof, sewer lateral, chimney). Los Angeles and some Bay Area cities have mandatory seismic retrofit programs for certain property types.
