Novato is mostly 1960s–90s single-family neighborhoods, plus newer development at Hamilton and the lagoon homes of Bel Marin Keys.
Novato is a bit warmer and drier than southern Marin, so mold here comes more from water than fog. The usual culprits are aging supply lines, water heaters and slow drain leaks under sinks in houses built decades ago, plus crawlspaces that stay damp near the marsh-edge neighborhoods. In bigger tract homes, attics with blocked soffit vents can build up condensation on the underside of the roof deck.
Moisture sources to check: under-sink cabinets, the area around the water heater, laundry rooms, and crawlspace vapor barriers that have shifted or torn.
Is water still coming in? Drying it out fast comes first: see Marin water damage help. For general guidance, see the EPA's mold resources.
