The 2016 California mold law, SB 655 applies to hotels, motels, apartment houses & dwellings (including houses and homes) regardless of the date of construction. Non-dwellings are excluded from SB 655.
The California Department of Public Health (CDPH) has determined that the presence of water dampness, visible mold, or mold odor in schools, workplaces, residences, and other environments is unhealthy. It recommends addressing water damage, dampness, visible mold, and mold odor by (a) identifying and correcting the source of water that may allow microbial growth or contribute to other problems, (b) the rapid drying or removal of damp materials, and ( c) the cleaning or removal of mold and moldy materials as quickly and safely as possible. These guidelines are similar to EPA and CDC guidelines regarding mold conditions and corrections. Using bleach to clean up mold or simply painting over the problem are not solutions to visible mold conditions in an indoor environment.
SB 655 provides guidance to local code enforcement and other public health officers that mold growth is a health and safety concern when it endangers the life, limb, health, property, safety, or welfare of the public or the building’s occupants. A Health officer or code enforcement officer must make this determination. Such ‘qualified’ mold is illegal under State Housing Law. Local agencies are mandated to enforce the State Housing Law and have the authority to issue notices to property owners to abate qualified mold growth as routine housing code enforcement.
The presence of mold that is minor and found on surfaces that can accumulate moisture as part of their proper functioning and intended use is exempt from enforcement under SB 655. Such mold is a ‘housekeeping’ task that is the occupant’s responsibility.
Landlords are required to keep their units safe and habitable, and free from violations of the State Housing Law. This obligation may not be waived or bypassed by any agreement to the contrary. SB 655 amends the landlord-tenant law so that landlords are not required to remediate mold unless they have notice of the mold or if the tenant is in violation of specific affirmative obligations.
Regardless of this Civil Code provision, under SB 655 substandard buildings remain subject to code enforcement by local agencies under the State Housing Law, which requires enforcement agencies to give notice to owners. Dwellings with unlawful mold may be deemed uninhabitable and may be required to be vacated and/or subject to other remedies including fines and penalties.
