Homes in San Francisco and how they leak

Victorians, Edwardians and stucco row houses from before 1940 make up much of the city, most divided into flats or condos, with garages at ground level and living space above. Galvanized supply lines and cast iron drains are common. The Sunset and Richmond have rows of 1930s to 1950s houses with similar layouts.

Local issues that cause water damage

Leaks between units

A failed supply line or overflowing fixture upstairs damages the flat below. See ceiling water damage.

Garage and ground-floor flooding

Low spots such as the area around 17th and Folsom streets flood when the combined sewers are overwhelmed in atmospheric river storms.

Roof and window leaks

Flat roofs, skylights and old wood windows let wind-driven rain in during winter storms.

Questions from San Francisco homeowners

My upstairs neighbor's leak damaged my flat. Who pays?

Your own policy usually pays for your unit and belongings first; insurers settle fault between them. In a condo building, the association's policy may cover shared structure.

Can old lath and plaster be dried?

Usually, with patience. Plaster dries slower than drywall, and readings confirm when it is done.
