Why biohazard cleanup is needed in San Francisco

Combined sewers

Most of San Francisco uses a combined sewer system for sewage and rain, and heavy storms can back water up into low spaces.

Multi unit buildings

In shared buildings, contamination and odor can spread to neighboring units.

Trauma scene rules

California requires trauma scene waste practitioners to register with the California Department of Public Health.

Hoarding

Hoarding cleanup in older apartments often uncovers pests, mold and hidden damage.

Permits and local rules

Cleanup itself does not usually need a permit, but the repairs that follow often do. Inside the city of San Francisco, larger drywall, electrical and plumbing repairs can require permits from the San Francisco Department of Building Inspection. Homes in other cities, such as Daly City, Oakland or San Mateo, follow the rules of that city or county.

In California, most construction and repair work above a small dollar amount must be done by a contractor licensed by the Contractors State License Board. You can check a license on the board’s website.

Seasonal risks in San Francisco

If anyone is hurt or in danger, call 911. After a death or a crime, the police and medical examiner must finish their work before cleanup begins.

  • Storm season: heavy rain can bring sewage backups.
  • Summer: heat speeds up decay and odor.
  • Fall and winter: rodents move indoors.
  • All year: hoarding and trauma cleanup can be needed at any time.

Be prepared

  • Know where your home’s sewer cleanout is
  • Ask a plumber about a backwater valve if sewage has backed up before
  • Check whether your policy includes sewer backup coverage
  • Report sewer problems in the street to SF311
  • Seal gaps where rodents can get in
