San Diego County, California

What this place does to a house

• Termite pressure here is real. Mulch piled against siding is the #1 way homeowners invite them in — keep it 6 inches below any wood.
• Freezes are rare here — which is exactly why they do damage. Nobody's plumbing is ready for the one week it matters.
• Your AC works harder than your heat here. Its maintenance schedule matters more than the furnace's — we've planned accordingly.

The numbers we plan around

Frost

First frost usually lands around December 1, and the last one lets go around March 19 — figure ~37 freezing days in between.

The air

Desert-dry — easy on framing, hard on gaskets, finishes, and anything rubber.

The load

The AC works harder than the heat here, and its maintenance schedule matters more.

Termites

Moderate pressure across this part of the country — a regional band, not a guess at your street.

Radon

EPA Zone 2 — the middle band. A one-time test settles it.

Wildfire

High wildfire risk — defensible space is a maintenance item here, not landscaping.

What jobs cost here

Labor here runs about 25% above the national average — every price band on this site adjusts for it.
