The new cooling mandate in Spokane is expected to reduce heat-related health risks for renters, who are statistically more vulnerable to heat exposure than homeowners. A study cited by Grist found renters are three times more likely to require medical care for heat-related illnesses. Without adequate cooling, extreme temperatures can lead to severe health issues, including heat stroke and dehydration. Tenant advocates warn that flexible measures, such as maximum indoor temperature limits, may allow landlords to avoid installing air conditioning, which is considered essential during severe heat waves.
