A few days ago, Columbia Heights blogger The Heights Life shared a rather miserable plight with the Twittersphere: “We have no AC and haven’t for NINE DAYS! Anyone know if our landlord has any legal requirement to keep us cool?” Well, actually, they probably do. According to The Housing Regulations of the District of Columbia (Section 510.10 of the DCMR14: Title 14, chapter 14), “The owner of a rental habitation, who provides air conditioning as a service either through individual air conditioning units or a central air conditioning system, shall maintain such unit or system in safe and good working condition so that it provides an inside temperature at least fifteen degrees Fahrenheit less than the outside temperature.” If your landlord is cheaping out and depriving you of that sweet, recirculated cold air, you can call DCRA at (202) 442-4400 to report the violation.
