Manhattan sidewalks must remain clear for pedestrian passage; DSNY and DOT enforce obstruction and snow-removal rules with fines from $100 upward.
New York County (Manhattan) sidewalk obstruction is governed by NYC Administrative Code Title 16 (Sanitation) and Title 19 (Transportation), plus Rules of the City of New York Title 34. Merchandise displays, A-frame signs, dining setups, and construction materials generally cannot block the pedestrian clear path (typically 8 feet minimum on commercial sidewalks). Snow and ice must be removed by adjacent property owners within 4 hours of snowfall ending during daylight, by 11 am if ended overnight, or by 9 am if it ended after 9 pm the previous day (Admin Code 16-123) — the 4-hour rule. Fines start at 100 dollars and escalate. DSNY enforces sanitation/snow rules; DOT enforces scaffolding, signs, and obstructions; NYPD also issues summonses.
