Sewage & Biohazard Cleanup questions
Do I need a permit for repairs in Palo Alto?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Palo Alto Development Services.
Does insurance cover earthquake damage in Palo Alto?
Not by default. Earthquake coverage is a separate policy, often through the California Earthquake Authority, and it has its own deductible.
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.
