The Los Angeles County Board of Supervisors has passed a new ordinance aimed at helping renters in unincorporated areas stay cool during extreme heat. The board approved a measure that mandates landlords maintain indoor temperatures at or below 82°F. While not a directive for air conditioning, the ordinance encourages landlords to explore other cooling strategies, such as weatherproofing windows and roofs, installing ceiling fans, and using blackout curtains.
This indoor heat ordinance primarily targets vulnerable renters, especially those in older buildings located in unincorporated regions of the county. A 2023 study by the Los Angeles County Department of Public Health highlighted the increasing frequency of heatwaves and higher temperatures, which pose significant health risks, including heat-related illnesses and exacerbated chronic conditions.
Under the new policy, renters are also allowed to install cooling solutions like window A/C units and blackout curtains without fear of retaliation from landlords. This provision will go into effect within 30 days.
By 2027, landlords will be obligated to meet the 82°F indoor temperature requirement through various means, such as applying reflective coatings to roofs, adding shading, installing ceiling fans, or enhancing landscaping. However, smaller landlords with 10 or fewer units will initially only be required to maintain the temperature standard in at least one habitable room. These landlords will have until January 1, 2032, to fully comply with the indoor cooling regulations.
The amendment also mandates county staff to explore additional funding options to support landlords in achieving these cooling objectives.
