Solar site surveys · New YorkA technician on the roof, in the attic and at the service panel, with the survey read against the code editions, AHJs and utilities that apply in New York.
New York runs two code systems: the five boroughs of New York City write their own construction, electrical and fire codes, while the rest of the state enforces the 2025 Uniform Code, in effect since December 31, 2025. Most new residential rooftop systems still net meter under Phase One NEM but pay a monthly Customer Benefit Contribution per kW. Surveys in the city are shaped by FDNY rooftop clear-path rules and Con Edison's network grid; everywhere, plan for snow and coastal wind loads.
The capture spec is the same everywhere. What the engineer and the plan reviewer read it against is not.
The NYC Building Code sets a 25 psf ground snow load for roof design in the five boroughs. Upstate snow loads are much higher and vary by town, so take the design value from the local building department.9
In New York City, ordinary (Risk Category II) buildings are designed for a 117 mph ultimate wind speed, with wind loads calculated under ASCE 7. Attachment spacing near roof edges and corners follows from that.9
FDNY rules decide how much of a New York City roof is usable. Flat roofs need a clear path and perimeter landing areas, and brownstone-type homes with a mostly flat roof are treated as flat roofs even where part of the roof is pitched.8,7
Con Edison's network grids, used in most of the dense boroughs, limit export relative to load, and any upgrade may involve street work. Note the service type and main panel during the survey so the interconnection path is known early.10
Who reviews the plan set, and what the state layers on top.
The Public Service Commission's SIR applies to the state's major investor-owned utilities. LIPA is a public authority, and some local utilities outside PSC oversight have their own interconnection and net metering rules. Three Long Island villages (Rockville Centre, Freeport and Greenport) are outside LIPA's service.17,18,19
Serves New York City and Westchester. Installers apply through PowerClerk, and systems of 50 kW or less go through the SIR small-DG process. Much of Manhattan, Brooklyn, Queens and the Bronx is on underground network grids, where how much a system can export depends on its size relative to the building's load.20,10
Interconnection page ↗PSEG Long Island runs the grid owned by the Long Island Power Authority (LIPA) for about 1.2 million customers on Long Island and in the Rockaways. Residential solar customers there cannot opt into the Value Stack.19,21
Interconnection page ↗One standard, one visit, the same record in New York as everywhere else. What it gets checked against is the code stack above.
It depends on location. Outside New York City, the 2025 Uniform Code (in force since December 31, 2025) applies the 2023 NEC. New York City's 2025 Electrical Code, effective December 21, 2025, is based on the 2020 NEC with city amendments.2,3
Not for the 2025 codes. The Department of State says the 2025 Uniform Code and Energy Code books have no supplements, because the state amendments are written into the books and Title 19 NYCRR.1
Yes. Residential systems interconnected since January 1, 2022 stay on Phase One net metering but pay a monthly Customer Benefit Contribution per kW DC. The rate is reset every year; in 2026 it is $1.29/kW at Con Edison and $1.13/kW at LIPA.21
The utility does, under the state's Standardized Interconnection Requirements for systems up to 5 MW at the investor-owned utilities. Con Edison takes applications through PowerClerk, with a small-DG track for systems of 50 kW or less. LIPA/PSEG Long Island runs its own process.18,20,17
