If the Landlord Knows or Believes

Residential landlords shall provide written disclosure to prospective and current tenants of the affected units when the residential landlord knows, or has reasonable cause to believe, that mold, both visible and invisible or hidden, is present that affects the unit or the building and the mold either exceeds the permissible exposure limits to molds established by subdivisions (a), (b), and (c) of Section 26103 or poses a health threat according to the department’s guidelines as developed pursuant to Section 26105.

Air and Surface Testing is Not Required

Prospective and Current Tenants Must be Notified

The written disclosure required from the landlord shall be provided:

  • To prospective tenants prior to entering into the rental or lease agreement.
  • To current tenants in affected units as soon as is reasonably practical.

Written Disclosure Exemption

A residential landlord shall be exempt from providing written disclosure to prospective tenants pursuant to this section if the presence of mold was remediated according to the mold remediation guidelines developed by the department pursuant to Section 26130.
