Title Residential Landlords in California Now Have to Provide Prospective Tenants with CDPH Booklet on Dampness and Mold
Introduction LA Testing offers laboratory services, sampling supplies, test kits, building inspection tools and personal protective equipment to identify and mitigate exposure risks to mold and other indoor environmental quality concerns.

Huntington Beach, CA, February 11th, 2022

Beginning on January 1st of this year, residential landlords in California are now required to provide a physical copy of a 4-page booklet from the California Department of Public Health (CDPH) to prospective residential tenants prior to entering a rental or lease agreement in accordance with the 2001 Toxic Mold Protection Act (HSC #26148). The booklet, Information on Dampness and Mold for Renters in California, explains the potential health risks that may result from exposure to mold. It was produced by CDPH in 2020 and is available in both English and Spanish versions.

The main points of the booklet include:

  • Living in damp or moldy buildings increases the chances of respiratory problems like asthma.
  • The critical warning signs are visible mold, water damage, damp materials, or a mold smell.
  • Dampness is needed for mold to grow, so if dampness is controlled, mold can be controlled.
  • Dampness or mold indoors may make housing substandard, per the California Health & Safety Code.

"It has long been recognized that exposure to elevated levels of mold can cause respiratory irritation, allergic reactions, and may even lead to asthma attacks for some people with the condition,” said Michael Chapman, Laboratory Manager of LA Testing’s Huntington Beach facility. “For many people, their home is where they spend most of their time. Understanding the connection between mold and moisture is important for a healthy home. Residents of California concerned about mold and moisture can turn to the experts at LA Testing. With multiple laboratories, LA Testing offers mold, bacteria, radon, asbestos, lead, and other environmental tests for common exposure risks. We also provide sampling supplies, easy-to-use test kits, air monitoring instruments, building inspection tools, and personal protective equipment.”
