The best NYC zoning analysis software
There’s no single “best” tool — there’s the right tool for whether you need property data, a quick capacity read, or a full feasibility answer. Here’s an honest map of the NYC field and where each one fits.
Envelope

PropertyScout
Best for broker air-rights & site-findingA focused NYC zoning and air-rights product with strong deal-sourcing workflows for commercial brokers hunting assemblages.
PropertyShark
Best for property records & compsThe reference NYC property database — ownership, sales, permits, and zoning fields with deep history and multi-market coverage. Data, not a feasibility answer.
Buildout
Best for a quick buildable-area readFast, approachable NYC zoning automation that surfaces buildable area and ADU potential for a single lot.
TestFit
Best for generative site planningA cross-market generative engine for laying out buildings, parking, and units. Strong for design teams and layout-driven, lower-density sites.
Gridics
Best for multi-city / municipal analysisA 3D zoning-code and development-analysis platform spanning many cities, often sold to governments and enterprises.
Agora
Best for investor & capital managementInvestment-management software for sponsors — investor portal, fundraising, distributions, and reporting. The back office behind a deal, not the feasibility in front of it.
