LA County has adopted an ordinance capping indoor temperatures in rental units at 82 degrees Fahrenheit in unincorporated areas, aiming to protect renters from extreme heat while providing phased compliance and support for small landlords.
The Los Angeles County Board of Supervisors has approved the region’s first ordinance establishing a maximum indoor temperature for rental units in unincorporated areas, aimed at protecting residents from extreme heat. Introduced by Chair Pro Tem Hilda L. Solis and supported by Supervisor Lindsey P. Horvath, the measure sets a limit of 82 degrees Fahrenheit indoors and grants tenants the right to use portable cooling devices such as plug-in air conditioners, fans, and blackout curtains without fear of eviction, retaliation, or extra charges. The ordinance also includes protections for tenants by prohibiting rent increases, fees, or harassment tied to the use of cooling devices.
The measure addresses the growing climate threat in unincorporated areas in the San Gabriel, San Fernando, and Antelope valleys, where prolonged heat waves and older, poorly cooled housing stock place renters at higher risk for heat-related illnesses. Development of the ordinance followed a 2022 motion by Solis directing County departments to explore indoor temperature thresholds, with input from the Departments of Public Health, Consumer and Business Affairs, the Chief Sustainability Office, and County Counsel. Testimonies from tenants, such as members of the organization SAJE, highlighted how worsening summer heat makes daily life increasingly unsafe and uncomfortable.
The ordinance takes effect in 30 days, with phased compliance requirements for small landlords—ensuring one habitable room meets the temperature standard by January 2027 and all habitable rooms by January 2032. Landlord enforcement will begin in 2027, with possible extensions for major improvements. To help property owners meet the standard, Solis introduced a related motion for technical and financial assistance, with a funding plan expected within six months. This dual approach aims to protect vulnerable renters while supporting landlords in adapting to the realities of a hotter climate.
