San Diego's mild climate is one of its biggest selling points — and it creates a false sense of security for home buyers reviewing inspection reports. The assumption is that nothing wears out in San Diego because the weather is perfect. That's not quite right.

Salt air corrosion affects homes within a few miles of the coast. Clay soils in hillside neighborhoods like Mission Hills, Normal Heights, and parts of El Cajon create ongoing drainage and foundation challenges. And because air conditioning is rarely needed near the coast, HVAC systems sometimes get neglected for years — until you move in and discover the furnace is 30 years old and hasn't been serviced since the Clinton administration.

Termites are a constant presence in San Diego County. Wood-destroying organism (WDO) inspections are typically done separately from standard home inspections here, and the findings frequently come back with active infestations or previous damage. Most real estate transactions in San Diego include a WDO report — if yours doesn't have one, ask for it.

Climate: Mediterranean coastal climate. Mild year-round with summer morning fog (June Gloom). Coastal areas stay below 90°F; inland communities like El Cajon and Santee experience significant heat. Annual rainfall averages 10–12 inches, mostly November through March.

County: San Diego County

Common Considerations in San Diego

  • Salt air corrosion on exterior metal components near the coast

Key Neighborhoods: North Park, South Park, Hillcrest, Mission Hills, Normal Heights, Pacific Beach, Ocean Beach, Point Loma, La Mesa, Chula Vista

Local Requirements: San Diego requires a Real Estate Transfer Disclosure Statement. Some properties require sewer lateral inspections through San Diego Metro's Sewer Lateral Rehabilitation Program. Point Loma and older sewer-connected neighborhoods may trigger lateral testing requirements at sale.
