details ▸

Heat is required October 1 through May 31: at least 68°F from 6am to 10pm when it is below 55°F outside, and 62°F overnight whatever the temperature outside. Hot water must be at least 120°F, 24 hours a day, all year.

If your apartment is colder than that, file a complaint with 311 and keep the service request number so you can track it. Never use a gas oven or range for heat, which can produce dangerous levels of carbon monoxide.
