New York City is tightening rules on sidewalk sheds and proposing new designs intended to remove unnecessary structures faster while making required sheds less disruptive to pedestrians.
Mayor Zohran Kwame Mamdani and Department of Buildings Commissioner Ahmed Tigani announced the changes in August as the city works to reduce the number of sidewalk sheds.
As of Aug. 17, the city had 7,427 permitted sheds, more than 1,000 fewer than at the same time last year and nearly 10% fewer than when Mamdani took office Jan. 1.
“New Yorkers have gotten used to sidewalk sheds darkening our streets and taking up precious public space, but it doesn’t have to be this way. There are already close to 10% fewer sheds up than when we took office. With better designs and stronger enforcement, we are going to keep bringing down the number of sheds, opening up our sidewalks and making them safer, brighter and more welcoming for everyone,” said Mayor Mamdani.
Under new Department of Buildings rules, sidewalk shed permits must be renewed every 90 days instead of annually. Property owners must explain what repairs require the shed and provide information about progress toward completing the work.
The rules also create graduated monthly penalties after 180 days for property owners who leave sheds in place without active work or fail to complete facade repairs within a reasonable period. Penalties can be paused when owners show meaningful progress. DOB expects to begin imposing the penalties in early 2027.
The changes could affect Brooklyn residents and businesses by reducing the amount of sidewalk space covered by sheds and improving visibility and pedestrian access. New guidance will limit required shed coverage on large properties, including NYCHA campuses, schools and medical facilities, to a maximum of 40 feet from a building.
The city is also proposing six new sidewalk shed designs developed by architecture and design firms Arup and Practice for Architecture and Urbanism. The designs are intended to provide more light, visibility and pedestrian space while maintaining overhead protection.
The proposed designs were published in the City Record, with the public comment period running through Sept. 24. DOB is conducting outreach to property owners about the new requirements as the city prepares to enforce the updated rules and promote wider use of the new designs.
