The best NYC zoning analysis software
There is no single best tool, only the right tool for the job: property data, a quick capacity read, or a full feasibility answer. Here is an honest map of the NYC field and where each one fits.
Who does what.
Envelope
NYC-native. Runs any lot to an as-of-right FAR, a 3D massing with per-floor sketch plans, City of Yes programs, air rights, an income-approach valuation, and a development pro forma. One report from $149, no subscription.
What’s in a study →PropertyScout
A focused NYC zoning and air-rights product with strong deal-sourcing workflows for commercial brokers hunting assemblages.
Envelope vs. PropertyScout →PropertyShark
The reference NYC property database: ownership, sales, permits, and zoning fields with deep history and multi-market coverage. Data, not a feasibility answer.
Envelope vs. PropertyShark →Buildout
Fast, approachable NYC zoning automation that surfaces buildable area and ADU potential for a single lot.
Envelope vs. Buildout →TestFit
A cross-market generative engine for laying out buildings, parking, and units. Strong for design teams and layout-driven, lower-density sites.
Envelope vs. TestFit →Gridics
A 3D zoning-code and development-analysis platform spanning many cities, often sold to governments and enterprises.
Envelope vs. Gridics →NYC Zoning AI
A subscription zoning-lookup tool that returns FAR, density, height, yard, parking, and use-group values for a lot as an Excel workbook, with an ADU checker and drawn-area property search. Priced by monthly search and report allowance.
Envelope vs. NYC Zoning AI →Agora
Investment-management software for sponsors: investor portal, fundraising, distributions, and reporting. The back office behind a deal, not the feasibility in front of it.
Envelope vs. Agora →The fastest way to decide? Run your own lot.
