Local homes
A diverse mix of Victorian-era homes, mid-century suburban tracts, and modern hillside estates. The downtown area features some of the county's oldest residential buildings.
What we see in San Rafael
Seasonal flooding and high water tables in certain low-lying areas can cause significant mold issues. Older homes with crawlspaces are particularly susceptible to moisture accumulation.
