The building super’s guide to trash chutes

A trash chute is a vertical shaft with a self-closing intake door on every floor, ending in a compactor or refuse room. It stays safe and odor-free when the doors latch, the sprinklers are clear and the shaft is degreased on a schedule. Here’s what every super and manager should know.

By Chute Cleaning Division, cleaning chutes since 1994. Last reviewed October 22, 2026. Rules are summarized from the linked official sources; check with your engineer or code consultant for your building.

The parts of a chute

PartWhat it doesWhat goes wrong
Intake (hopper) doorWhere trash goes in on each floor; closes and latches on its ownGrease, sticking open, worn closers and latches
BaffleThe vinyl piece along the bottom of the door that seals the gapCaked grease, so smoke and odor reach the hallway
ShaftCarries trash from the top floor to the bottomGrease and residue film that smells and feeds pests
Sprinkler headsFire protection inside the chute and at the bottomCaked over, damaged or blocked
Compactor / refuse roomCollects and compacts the trashSpillage, standing water, propped-open doors

Metal, masonry and incinerator chutes

Post-war buildings usually have smooth metal chutes. Many pre-war buildings have masonry chutes, and many of those are flues that once fed the building’s own incinerator. Larger apartment buildings built after May 20, 1968 had to have compactor systems instead (NYC Admin Code §24-119), and most building incinerators were shut down in the early 1970s. NYC’s chute rule expressly allows the old flues to be used as refuse chutes (1 RCNY §24-01).

Masonry is rough and porous, so grease settles into it instead of running off. Old incinerator chutes take more degreaser, more passes and a closer look than metal ones. See incinerator chute cleaning.

What NYC’s chute rule requires

NYC’s Buildings rule 1 RCNY §24-01, “Refuse Chutes and Refuse Rooms” covers most of what supers deal with day to day:

  • Chute openings need approved self-closing hoppers, with hopper doors rated for at least one hour of fire resistance.
  • Refuse room doors must be self-closing and rated at least 1½ hours, and it is unlawful to keep them open.
  • The refuse room needs sprinklers, a hose connection and a concrete floor sloped to a drain.
  • Compacting equipment must run before trash builds up to within three feet of the lowest intake door.
  • Chutes, refuse rooms and hoppers must be kept clean, sanitary and free of vermin and odors.
  • The owner must run a pest-treatment program for them and keep records for the Department of Buildings.

Outside the city, New York State’s fire code calls for sprinklers at the top of trash and linen chutes, in the room at the bottom, and on alternate floors where a chute runs through three or more floors (NY Department of State). New Jersey, Connecticut and Pennsylvania have their own codes.

Who is responsible for what

WhoResponsible for
Owner / managing agentKeeping the chute and refuse room clean, sanitary and pest-free; the treatment program and records; doors and fire protection in working order
Super / building staffDaily upkeep, the compactor, checking doors latch, posting notices
Chute cleaning contractorDeep cleaning the shaft, doors, baffles and compactor area on a schedule, and reporting problems
TenantsBagging and tying trash, keeping banned items out, closing the door

How often to clean

No NYC rule sets a cleaning frequency; the rule sets the result: clean, sanitary, free of vermin and odors. Our recommendation from 32 years of doing this:

BuildingRecommended
Hospitals, hotels, heavy-use buildingsQuarterly
Most apartment buildings, co-ops and condosTwice a year
Light-use buildingsAt least once a year

If tenants are complaining about smell, roaches or flies, the chute is already overdue.

Rules to post for tenants

  • Bag and tie all trash. Double-bag anything wet or smelly.
  • No liquids, loose cat litter, bedding, hangers, blinds or pizza boxes.
  • Nothing bigger than the hopper, and nothing burning.
  • No rechargeable batteries: they’re illegal in NYC trash (DSNY).
  • Recyclables go in the recycling space, not the chute.
  • Close the chute door behind you.

FAQ

More chute questions

What can’t go down a trash chute?

Keep out liquids, loose cat litter, unbagged food, bedding and cloth, hangers, blinds, pizza boxes, anything bigger than the hopper, recyclables and anything burning. Rechargeable batteries are illegal in NYC trash, chute included. Bag and tie everything else.

Do trash chutes attract roaches and rats?

They can. A chute and compactor that aren’t cleaned give pests food, moisture and a path through every floor of the building. Regular cleaning, bagged trash and a pest program cut pest pressure. In NYC, owners must treat chutes and refuse rooms as often as needed and keep records of the treatments.

Is a compactor chute the same as a trash chute?

Yes. In most buildings the “compactor chute” is the trash chute, and the compactor is the machine at the bottom that presses the trash into bags or containers. A proper cleaning covers the chute and the compactor area, because grease and spillage build up where the two meet.

When did NYC buildings stop using incinerators?

In stages. Larger apartment buildings built after May 20, 1968 had to have compactor systems instead, and most building incinerators were shut down in the early 1970s. Later laws required the remaining refuse-burning equipment to be stopped and sealed. That’s why so many older buildings have a chute but no incinerator.
