(Washington, DC) Does your landlord provide air conditioning? If so, your unit must be kept at least 15 degrees cooler than the outside temperature.
If you rent an apartment or house in the District, the Department of Consumer and Regulatory Affairs (DCRA) regulates air conditioning. If your lease includes air conditioning through individual units or a central air conditioning system, then the inside temperature must be at least 15 degrees cooler than the outside temperature.
Individual units or central systems must be inspected each year, between September 1 and May 1. This inspection must be done by a master refrigeration and air conditioning mechanic. Owners must file inspection results with DCRA within 15 days of inspection.
Failure to comply with a Notice of Violation may result in the District imposing a fine of $1,000 and imposing penalties and fees on the owner. Residents can report violations by calling (202) 442-4400.
(Air conditioning regulations are from Section 510.10 of the DCMR14: Title 14, chapter 14.)
