New York City Local Law 11 (Local Law 11/98) requires that all window air conditioners installed in multi-dwelling buildings (6 stories and taller) be secured properly. NYC Department of Building has issued below Installation Guidelines for window mounted air conditioners:

  • Make sure the unit is installed securely. Support the unit from underneath, or firmly fasten it from inside with angles. You may use metal brackets, mounting rails, etc.
  • Supporting metal brackets, interior angles, etc. should be structurally fastened to the building and must be strong enough for the size and weight of the AC unit.
  • Objects or shims used to adjust the position of the AC unit must have an independent source of fastening or attachment.
  • Secure leveling objects to prevent movement and shifting due to vibrations from the AC unit, wind and other weather conditions.
  • Install the AC unit so it remains in place when the window is opened, or affix it so that the window can’t be opened accidentally.
  • Tilt the unit slightly to provide water drainage, but don’t over tilt.
  • Do not use loose objects - such as wood blocking, bricks, telephone books, gypsum board or cans - to support the leveling of the AC unit.
  • Do not place anything (TV antennae, satellite dishes, plants, etc.) on top of the AC unit.
  • Do not block fire escape windows or other exits with the AC unit.

In NYC, Window Air Conditioners must be securely installed per NYC Local Law 11/98
