Santa Rosa's mold calls come from every kind of home: older houses in central neighborhoods with crawlspaces and original plumbing, mid-century homes with low-slope roofs, and homes in Coffey Park, Fountaingrove and Skyhawk rebuilt after the 2017 and 2020 fires.

Common sources in Santa Rosa

• Plumbing leaks under sinks, behind dishwashers and at water heaters.
• Roof leaks that soak attic insulation during atmospheric-river storms.
• Crawlspaces that take on water in wet winters.
• Storm runoff in post-fire areas. The City's Rain Ready page warns that flash floods and debris flows are more likely during intense rain.

Renters

Under California housing law, visible mold can make a rental substandard (CDPH). Inside city limits, the City of Santa Rosa handles code enforcement; see our rental mold article.
