West county is green for a reason: shade, fog and rain. Homes around Sebastopol often dry slowly, and those near the Laguna de Santa Rosa can see floodwater when the Russian River is high. In February 2025, the Sebastopol Times reported the Laguna rising onto part of Morris Street as the river peaked (Sebastopol Times).
West county mold risks
- Crawlspace moisture under homes on damp, shaded lots. See crawlspace moisture.
- Laguna flooding in low areas. See Sebastopol flood mold cleanup.
- Condensation in older, less-insulated homes.
- Roof leaks under trees that drop debris into gutters and valleys.
Permits and rentals
Inside city limits the City of Sebastopol handles building and code questions; many west county addresses are unincorporated and fall under the County. If you rent, see our rental mold guide.
