Free NYC property research tools
Resolve the property before you compare its records.
These public utilities handle small, defined research tasks. They do not create a full property report, spend an account search credit, or treat an empty result as proof of compliance, safety, ownership, or legal use.
Address → property identity
NYC BBL and BIN lookup
Resolve an NYC address to its borough-block-lot, building identification number where available, borough, block, and lot using one bounded NYC GeoSearch request.
Open lookup →Review workflow
NYC due-diligence checklist
Work through property identity, DOB, HPD, occupancy, ACRIS, zoning, and contextual sources in a browser-friendly checklist that is also designed to print cleanly.
Use checklist →Public-tool boundary
A basic lookup is not a property report. Full LotContext research remains private and keeps the existing account verification, usage limits, source-call budgets, and report authorization controls.
