The short answer
Under NYC Administrative Code § 16-118(2)(a), the owner, lessee, tenant, occupant, or person in charge of a building or lot is legally responsible for keeping the sidewalk, flagging, and curbstone abutting the property clean — not the City. This duty applies even if someone else (a passerby, a delivery driver, the wind) caused the mess. DSNY's own guidance is explicit on this point: property owners “must clean and sweep the sidewalk, tree beds, and gutters next to their properties… This rule applies even if someone else caused the dirty condition.”
What the law actually requires
Per NYC Admin Code § 16-118(2)(a), every owner/lessee/tenant/occupant/person in charge must keep clean and free from obstruction:
- The sidewalk, flagging, and curbstone abutting the building or premises
- Air shafts, areaways, backyards, courts, and alleys on the property
- The gutter area extending 18 inches from the curb into the street (the code says “one and one-half feet from the curbstone into the street”)
- Exception: owners are not responsible for debris that accumulates at catch basins within that 18-inch strip
“Clean” under the statute means free from “garbage, refuse, rubbish, litter, debris and other offensive material” — loose trash, stray bags, broken glass, sweepings, organic waste.
Who's actually liable
The person in charge of the building or premises — owner, lessee, tenant, or occupant — not the City, and not whoever littered. DSNY confirms you can be ticketed “for trash you should have cleared but didn't,” even after you report the littering yourself via 311.
For commercial, manufacturing, or industrial buildings (including mixed-use, but excluding solely residential buildings), the person in charge of the business bears this responsibility during business hours; residential owners bear it the rest of the time.
When DSNY actually checks
Sidewalk cleanliness isn't checked 24/7 — DSNY inspects during specific windows tied to property type:
| Property type | Enforcement window |
|---|---|
| Residential | 8:00–9:00 AM and 6:00–7:00 PM, seven days a week |
| Commercial | Two 1-hour windows per day; exact times depend on the DSNY routing section for that address |
| Mixed-use | Commercial hours if the ground-floor business is open; residential hours if permanently closed/vacant |
Frequently asked questions
Am I responsible for cleaning the sidewalk if I didn't cause the mess?
Yes. NYC Admin Code § 16-118(2)(a) places the cleaning duty on the owner, lessee, tenant, or occupant regardless of who caused the dirty condition — DSNY confirms this applies “even if someone else caused” it.
How far into the street am I responsible for?
18 inches (one and one-half feet) from the curb into the roadway, in addition to the full sidewalk width, except for debris that collects specifically at catch basins within that strip.
What counts as “dirty” under the law?
Garbage, refuse, rubbish, litter, debris, and other offensive material — this includes loose trash, stray bags, broken glass, and sweepings.
Does the City ever clean my sidewalk for me?
No. DSNY cleans City streets and public litter baskets, not private sidewalks abutting your building. That obligation is yours under § 16-118(2)(a).
What happens if DSNY finds a dirty sidewalk during an inspection?
They may issue a summons/civil-penalty notice to the property owner — see our DSNY sidewalk violation fines guide for the fine schedule and process.
