NYC Construction Intelligence

Data, unified.Decisions, grounded.

NYC construction runs on information silos. Zoning lives here, permit history there, ownership somewhere else, subsurface data nowhere. BuildNYC is the first platform to unify every data source — so you see what no single system shows alone.

Why unified data changes everything

The whole is greater than any single part.

Every firm in NYC construction operates from its own information. The developer knows their contractors. The broker knows the ownership. The attorney knows the filing history. The engineer knows what's underground. Each document, each system, each relationship — held separately, by separate parties, serving separate interests.

Individually, each piece is useful. Unified, they reveal something none of them could show alone — the complete record of a building, an owner, a contractor, or a market.

One platform. Every system. The full picture.

BuildNYC indexes DOB NOW job applications, permit issuances, stop-work orders, plan examination objections, and the legacy BIS permit system — over 2 million filings across all five boroughs. Data refreshes daily from NYC Department of Buildings feeds.
BuildNYC's Ownership & Entity Graph traces beneficial ownership across ACRIS deed transfers, HPD registrations, and LLC filings. You can identify the individual or entity that controls a building even when it is held through multiple shell companies or related LLCs.
Local Law 97 (LL97) sets carbon emissions limits for NYC buildings over 25,000 square feet, with penalty thresholds in 2024 and 2030. BuildNYC calculates per-building penalty exposure by comparing benchmarked emissions against the applicable carbon limit, generating an annual penalty estimate for each covered property in the five boroughs.
Yes. BuildNYC's Shield module scores every contractor across DOB NOW and BIS permit history, computing a Permit Abandonment Rate (PAR) from 29,000+ entities. See active jobs, stop-work order history, violation rates, and network risk derived from co-occurrence with other high-risk entities. Add any building to your portfolio and get alerted the moment a high-risk contractor files.
DOB plan examiners review construction documents before issuing permits. Approval time varies significantly by job type, borough, and work type. Based on 450,000+ measured permit approvals, median approval time for an Alteration in Manhattan is 20 days, but projects with contested objections can take 3–6 months. BuildNYC's Plan Review Intelligence module analyzes objection patterns by borough, discipline, and code section — with approval time distributions so you can forecast your timeline before filing.
BuildNYC uses a kriging interpolation model trained on 112,000+ soil borings and geotechnical investigation reports to predict subsurface conditions at any NYC coordinate. Outputs include bedrock depth, groundwater elevation, fill extent, and P10/P90 uncertainty bounds — before you commission your own geotechnical investigation.
BuildNYC serves anyone making decisions about NYC construction, development, or real estate — developers, brokers, general contractors, architects, subcontractors, structural and MEP engineers, material suppliers, attorneys, expediters, and PE firms. Any role where understanding who has worked with whom, what has been built, and what the data says about a building, owner, or contractor leads to a more informed decision.
Built for professionals who need the full picture.
