The Climatizing Our Overheated Living Spaces Regulation Amendment Act of 2025 aims to update the regulations regarding the provision of heat and air conditioning in rental housing within the District of Columbia. The bill proposes to amend Title 12-G of the District of Columbia Municipal Regulations by changing the required dates for landlords to provide these services. Specifically, it extends the air conditioning provision period to start from May 1 and end on October 1, while the heating period will now run from October 15 to April 15. Additionally, landlords will have the flexibility to transition from heating to air conditioning between April 15 and May 1, and from air conditioning to heating between October 1 and October 15, allowing for a two-week earlier and later transition than currently permitted.

Furthermore, the bill introduces minimum and maximum year-round internal temperature requirements for rental housing where tenants control heating and air conditioning. This aligns with similar regulations passed in Montgomery County. The changes are in response to rising average temperatures and increased reports from tenants regarding uncomfortable living conditions due to extreme temperature fluctuations. The bill is set to take effect on October 1, 2027, following the necessary approval processes.
