Red Stickers

DOB inspectors are on Corbin Place checking for structural stability issues. Photographed building numbers 286 and noted 295.

As per DNAinfo.com:

The Department of Buildings has to send an inspector to the Zone A buildings one by one to determine whether they're safe and structurally sound, Bloomberg said at a press conference.
Larger buildings will be allowed to self-certify whether their buildings are safe to enter, Bloomberg said.

Red stickers mean the buildings are not safe to enter, yellow means caution, and green stickers mean you can enter, Bloomberg said.

More information can be found here from the Buildings' Department website:
A NYC Department of Buildings green sticker issued after inspection authorizes re-occupancy of such building. In lieu of a Department inspection, an owner may obtain a green sticker upon satisfaction of both of the following:

1. Submission to the NYC Department of Buildings of a certified report by a NYS licensed professional engineer or registered architect certifying the following:
• There is no standing water in the building;
• The building is structurally sound;
• All required life safety systems, including but not limited to, fire alarms, sprinklers, standpipes,
carbon monoxide and smoke detectors, are intact and in good working order;
• If there is an elevator, at least one working elevator serves all floors; and
• The building is otherwise safe to occupy.
2. The building has electrical power or a working emergency generator to power all required life safety systems.

ALL SUBMISSIONS
All submissions including certified reports in accordance with the above shall be submitted to the following email address reoccupyzonea@buildings.nyc.gov or to one of the Department
Borough Offices. For any variation from the above requirements, the NYS licensed professional engineer or registered architect must first submit a request for variation determination to reoccupydeterminations@buildings.nyc.gov.
