New York City is changing how alterations to existing buildings are regulated.
Beginning July 17, 2027, the new NYC Existing Building Code, or EBC, will govern alteration applications filed for existing buildings across the five boroughs.
If your building runs on natural gas in New York City, you may be on a non-firm (interruptible) service agreement — and if so, October 1 is a hard compliance deadline you cannot afford to miss.
If your New York City building is subject to the City’s energy grading requirements, the 2026 Building Energy Efficiency Rating Label must be posted no later than October 31, 2026.
Annual pre-season heating system maintenance gives you an opportunity to make sure your boiler is ready before colder weather arrives and before you begin relying on it every day.
If your NYC property has an in-ground sprinkler system, a swimming pool, multiple water service lines, a chemically treated boiler, or a commercial kitchen, New York State law almost certainly requires you to have a backflow prevention device — and to have it tested every year.
The DOB and DEP violations NYC building owners get fined for most: LL152 gas piping, boiler inspections, LL84/LL97, No. 4 oil, and permits.
An NYC Local Law 152 inspection is a periodic visual inspection of a covered building’s exposed gas piping, performed by a New York City Licensed Master Plumber. The inspection focuses on what the plumber can safely and legally see and evaluate — exposed piping, valves, joints, meters, and any signs of leakage, corrosion, damage, or conditions that may be unsafe or out of code.
If you own or manage a NYC building over 25,000 square feet, Local Law 88 is one of the four building energy laws you have to think about — and it’s the one most owners understand the least. LL88 requires two things: upgrading the building’s lighting to meet the current NYC Energy Conservation Code, and installing submeters for non-residential tenant spaces over 5,000 square feet.
In New York City, a commercial backup generator usually belongs in one of three places: on the roof, at grade outside the building, or in a dedicated interior generator or mechanical room. The right answer depends less on convenience and more on code constraints: FDNY rooftop access rules, zoning screening and enclosure rules, structural capacity, flood exposure, exhaust routing, fuel storage or gas-service capacity, air-permit thresholds, and access for maintenance.
Installing or replacing HVAC in an NYC apartment building that still has people living in it is as much a logistics project as a mechanical one. The equipment decisions matter, but the schedule is usually decided by access — who can get in, when, with what insurance, and without cutting off heat, hot water, or cooling for longer than tenants can tolerate.
