Zoning, permits, market feasibility, and offering plan data — everything you need for pre-development due diligence.
Every development decision starts with research across 5+ city agencies — DOB for permits, DOF for tax lots, HPD for violations, ACRIS for title, and MLS for market comps. None of these systems talk to each other.
DOB, DOF, HPD, ACRIS, and DCP each have their own portal, format, and search logic. No unified view of a site.
NYC's zoning code is 1,000+ pages. Determining buildable area, FAR, setbacks, and use groups requires deep expertise.
Is this the right location? What are comps selling for? What's the absorption rate? All separate research tracks.
Compiling Schedule A data, amendment history, and unit pricing for new developments — a manual, error-prone process.
