Local risks
What causes water damage in Alameda
Original plumbing in older homes
44% of Alameda's housing predates 1960. Pipes that old narrow with rust, joints weaken and drain lines crack, so a small drip behind plaster or under a floor can go unnoticed until stains or soft spots appear.
Leaks between units
About 51% of occupied homes in Alameda are rented, and many are apartments or condos. A leak in one unit often reaches the units below, so landlords, associations and each tenant's insurer are involved.
Atmospheric rivers
Winter storms bring heavy rain, roof leaks and flooding.
Seasonal risks, licensing and FEMA history across the state are on the California page.
