NYC AC Law Owner Checklist (Printable)

Now through 2027

Estimate which bedrooms tenants may request, and size them in the building planner.
Check electrical capacity. Any new outlet or circuit needs a NYC licensed master electrician and a permit.
Check windows that lead to fire escapes. The Fire Code bars a unit there unless another unobstructed window in the room reaches the fire escape.
In a landmark building or historic district, check Landmarks permits for permanent or through the wall installs.
If you plan window heat pumps, look at the NYSERDA incentive. It needs at least 10 units and closes June 30, 2027 or when funding runs out.

Get the City notice. The City must publish it by January 1, 2028.
Give the notice to every tenant.
Post it prominently in the building.
From March 1, 2028, make every new lease and renewal say who pays the electricity for cooling, and include the notice.

Expect the City's notice within 10 days, naming the rooms and the start date: 60 days after the request.
For a rent regulated tenant, get consent to the work and any charges first. Coverage starts only after that consent.
For an Individual Apartment Improvement in an occupied rent stabilized apartment, get the tenant's written consent.

Equip every requested room with cooling able to hold 78°F or below from June 15 to September 15.
Use approved equipment: window and wall units need at least 20 BTU per hour per square foot.
Keep existing central and permanent systems able to provide adequate cooling.
If you can't make it, apply for a hardship extension: up to two years, renewable.
