    California law requires buildings and grounds to be kept clean and sanitary and free from debris, filth, rubbish, garbage, rodents and vermin. San Francisco requires property owners to keep their property free of vermin, and requires an owner or manager to respond to a tenant's bed bug complaint by hiring a licensed pest control operator.

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.

  • San Francisco Health Code §581(b)(6)
  • Electrical problems have been reported here.
    Worth checkingⓘ
    Look for defects in wiring and fixtures such as scorch marks, loose sockets or exposed wire, and check whether there are enough outlets in each room for how you would use it.

    California law requires an electric system, including lighting, wiring and equipment, in good working order. San Francisco's Housing Code treats hazardous wiring as a condition that makes a building substandard.
