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
| Part | What it does | What goes wrong |
|---|---|---|
| Intake (hopper) door | Where trash goes in on each floor; closes and latches on its own | Grease, sticking open, worn closers and latches |
| Baffle | The vinyl piece along the bottom of the door that seals the gap | Caked grease, so smoke and odor reach the hallway |
| Shaft | Carries trash from the top floor to the bottom | Grease and residue film that smells and feeds pests |
| Sprinkler heads | Fire protection inside the chute and at the bottom | Caked over, damaged or blocked |
| Compactor / refuse room | Collects and compacts the trash | Spillage, 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
| Who | Responsible for |
|---|---|
| Owner / managing agent | Keeping the chute and refuse room clean, sanitary and pest-free; the treatment program and records; doors and fire protection in working order |
| Super / building staff | Daily upkeep, the compactor, checking doors latch, posting notices |
| Chute cleaning contractor | Deep cleaning the shaft, doors, baffles and compactor area on a schedule, and reporting problems |
| Tenants | Bagging 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:
| Building | Recommended |
|---|---|
| Hospitals, hotels, heavy-use buildings | Quarterly |
| Most apartment buildings, co-ops and condos | Twice a year |
| Light-use buildings | At 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.
