New York City is rolling out new rules to reduce the number of sidewalk sheds. Zohran Mamdani announced the changes Friday, saying the city wants to limit how far sheds extend from buildings and increase enforcement against property owners who leave them up indefinitely.

Sidewalk sheds currently cover more than 380 miles of streets—about 7,500 city blocks—and some have remained standing for over 15 years.

Under current rules, sheds must extend at least half the height of the building under repair, meaning taller buildings often require much larger structures that can stretch far into sidewalks or open space. Beginning in August, however, sheds will be limited to extending no more than 40 feet from a building’s façade, regardless of the building’s height.

The city is also increasing enforcement against so-called “permanent” sheds. New rules from the New York City Department of Buildings will allow the agency to penalize property owners who keep sheds in place too long and require public updates on the status of each shed every 90 days.

In addition, inspection rules are changing for newer buildings. Well-maintained buildings under 40 years old will move from mandatory façade inspections every five years to every 12 years, with shorter visual check-ins every three years in between. The change is based on an 18-month review of façade inspection data.

New York City currently has nearly 8,000 active sidewalk sheds, about 1,000 fewer than five years ago, and officials say the new rules are meant to further reduce the number and keep sidewalks clearer for residents.
