Other risks in Berkeley
Hillside runoff and slides
Heavy rain sends water and mud toward homes on steep Berkeley Hills lots, especially where retaining walls and drains are old.
Earthquake pipe damage
The Hayward Fault runs through the city, and a quake can crack supply lines, gas lines, water heaters and foundations.
Student rental leaks
Rentals near campus change tenants every year, and slow leaks under sinks and showers can run for months unreported.
Older plumbing
Century-old homes have galvanized supply lines and cast-iron drains that leak, clog and corrode with age.
Signs you need sewage & biohazard cleanup

Sewage & Biohazard Cleanup questions
Do I need a permit for repairs in Berkeley?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Berkeley Permit Service Center.
Does insurance cover earthquake damage in Berkeley?
Not by default. Earthquake coverage is a separate policy, often through the California Earthquake Authority.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
