What to watch forⓘ

  1. Fire safety problems have been reported here.
    Worth checkingⓘ
    Walk the exit route from the unit to the street and check the stairs and hallways are clear of stored items, and that fire doors close properly.
    details ▸

    California law requires safe fire or emergency exits leading to a street or hallway, and requires stairs, hallways and exits to be kept litter free. Storage areas, garages and basements must be kept free of combustible materials. San Francisco's Housing Code separately treats inadequate exits and inadequate fire protection equipment as conditions that make a building substandard, which is the finding behind a notice of violation.

  2. Smoke detector problems have been reported here.
    Worth checkingⓘ
    Look for a smoke detector in each bedroom and in the common stairwell, and for a carbon monoxide detector if the unit has a gas stove, a gas heater or an attached garage.

details ▸

California law requires working smoke detectors in all bedrooms and other designated areas of a rental unit, and apartment complexes must also have them in common stairwells. Any unit with appliances that burn fossil fuels such as natural gas, propane or fuel oil, or with an attached garage, must also have working carbon monoxide detectors.

  • California Tenant Guide
  • Tenants here have reported mold.
    Worth checkingⓘ
    Look for dark spots on walls, floors and ceilings, and for dry or wet spots, flaking or bubbling, or a damp or moldy smell, especially in bathrooms and closets.
    details ▸

    San Francisco's Health Code treats visible or otherwise demonstrable mold or mildew in a residential building as a public health nuisance in its own right. Under state law, mold that the landlord has notice of and that affects livability or health can also breach the implied warranty of habitability.
