NYC rules that apply here

Based on the building’s size, age and type. These apply whether or not anything is open.

• Sidewalk shed / scaffold upAn active DOB NOW permit for a sidewalk shed, scaffold or construction fence. A shed is a monthly rental cost, and one that stays up for years usually means facade repairs are stalled. The permit has to be renewed while the shed stands; an expired shed permit is a violation.
• LL97: emission limits from 2024On DOB’s Local Law 97 list under Article 320: emission limits since January 1, 2024, report every May 1.
• LL87 energy auditOn DOB’s Local Law 87 list: an energy audit and retro-commissioning report every ten years, the year set by the block number’s last digit.
• LL88 lightingOn DOB’s Local Law 88 list: lighting in non-residential and common spaces had to meet code by January 1, 2025 (and tenant submeters in the largest buildings), with a report to DOB.
• HPD registration every yearRequired for every residential building with 3 or more apartments, between May 21 and September 1. Without it, an owner cannot bring a nonpayment case or certify corrected violations. Read the guide
• Lead-paint rules (Local Law 1)Built before 1960, so paint in the apartments is presumed to be lead-based: annual notices, turnover work, XRF testing and ten years of records. Read the guide
• Annual window-guard noticeEach January every tenant gets the window-guard notice; guards go on every window of an apartment where a child 10 or younger lives. Read the guide
• Heat and hot waterHeat season runs October 1 to May 31 (68°F by day when it is below 55°F outside, 62°F at night); hot water at 120°F all year. Read the guide
• Gas piping inspection every four years (Local Law 152)Every building except one- and two-family homes; the year depends on the community district. Read the guide
• Natural gas alarms by January 1, 2027Every apartment in a building with gas service needs a natural gas alarm (Local Law 157 of 2016, deadline set by Local Law 102 of 2025). Read the guide
• Façade inspection every five years (FISP / Local Law 11)Taller than six stories, so a qualified inspector must examine the exterior walls every five years and file with DOB. Read the guide
• Energy benchmarking and Local Law 97About 77,008 sq ft, over the 25,000 sq ft line: Local Law 84 benchmarking and the Local Law 97 emissions report are due May 1 if the building is on the covered list. Over 50,000 sq ft, a Local Law 87 energy audit is due every ten years. Read the guide
