Can you build a PSL Modular unit in New York?

The New York State Department of State, Division of Building Standards and Codes. Factory-manufactured (modular) buildings are built to the NY State Uniform Fire Prevention and Building Code, inspected by a recognized third-party agency, and bear a New York State Insignia of Approval issued under 19 NYCRR Part 1209. With the insignia, your local code enforcement permits the site work — foundation, utilities, zoning — without re-reviewing the structure.

No. A statewide ADU proposal in 2022 did not pass, so ADUs remain a local decision. That means very different rules across the state: some suburban jurisdictions on Long Island and in Westchester are restrictive, while many upstate towns are more flexible. Always confirm your specific municipality's zoning.

Partially. NYC's 'City of Yes for Housing Opportunity,' passed in December 2024, allows ADUs in more parts of the city — but with significant carve-outs: low-density R1, R2 and R3 areas are excluded unless they're in a transit-accessible district, and historic districts plus flood/coastal zones are restricted for certain ADU types. If you're in NYC, check your specific zoning district against the City of Yes rules.

Snow. Western New York (Buffalo's lake-effect belt), the Adirondacks, the Catskills, and especially the Tug Hill Plateau carry some of the heaviest ground-snow loads in the United States. That drives roof and structural design — a downstate spec will not pass upstate. PSL Modular engineers the snow load to your exact site.

Yes. These are strong cabin and glamping markets, and modular adds finished units quickly through a short building season. The structures clear via the state insignia; your work is county/town land-use, septic, access, and the local short-term-rental ordinance, which varies widely across upstate towns.
