Why San Diego homes are different

Mission Valley sits directly in the San Diego River floodplain, and coastal neighborhoods get a near-daily marine layer that keeps humidity higher than the region's low rainfall totals would suggest.

Older stucco-clad homes near the coast trap condensation behind the exterior finish more than the newer, better-vented construction common further inland, since stucco was never designed to dry out quickly.
