What exactly can you build here?
An architect-grade zoning study for any NYC lot. Every legal scenario modeled, every floor drawn, every constraint cited to the Zoning Resolution. Minutes, not weeks.
Free to look No account, no card. FAR, buildable SF and every legal scenario before you pay. Full report from $149.
One lot, 88 pages, page by page.
The pages on the right are taken straight out of the generated PDF for the lot on this placard. What a visitor sees is what a customer receives.
Anyone can tell you the FAR. Will it survive a DOB examiner?
So we grade ourselves against reality. The engine's output is compared to real filed DOB jobs: job number, filed floor area, filed unit count, across thousands of NYC lots. When it drifts from what examiners actually approved, we find out before you do.
Everything in it.
Not a summary and not a screening tool: the full study, drawn and cited, that an architect would hand you in week two of schematic design. Every report contains all of this. There is no cut-down version.
As-of-right, City of Yes UAP, Inclusionary Housing, Tower-on-Base, SRO. FAR, height and unit count per scenario, side by side. Split zoning and assemblage handled per edge. Tax eligibility: 421-a, J-51, ICAP, 485-x.
MORE →Per-floor plates with unit footprints, corridor and core placement, stair geometry, room dimensions. Cross-sections at the critical heights, setbacks at every plane. Native DXF, OBJ, GLB and IFC for Revit, AutoCAD, Rhino and SketchUp.
MORE →The full Zoning Resolution citation table. Special-district and overlay overrides applied automatically. Building Code analysis, Chapter 5. Defensible with any architect or DOB examiner.
MORE →White-label PDF and a live web view under your logo. Shareable link, no account needed on the other end. Free re-runs on the same lot as the design changes. Two years of hosted history.
MORE →The zoning analysis your architect charges thousands for, on demand.
An architect-grade feasibility study delivered as a live, interactive web report, the same analysis an architect spends weeks producing. Hand it to your architect as a starting point and save yourself the upfront engagement.
Handles the edge cases too: irregular lots, split-zoned parcels, and special zoning districts. The engine does the per-edge yard classification and overlay FAR overrides automatically.

ARCHITECT
“The zoning engine is genuinely world-class. Split-zone detection with weighted envelopes, anisotropic yard geometry, full Zoning Resolution and special-district interpretation, sky-exposure plane calculations, dormer allowances, PBA detection. An architect-level computation.”
Built for everyone who does the deal.
Brokers price and pitch it. Owners test what their site is worth building. Developers underwrite before they bid.
Win listings with architect-grade reports under your logo. Source cold leads by piercing the LLC. Track every client, target and active deal in one pipeline.
SEE THE WORKFLOW →“The NYC defaults on the valuation tool are scary good. I was plugging in Class 2 tax rates by hand before this.”
Understand your portfolio without hiring an analyst. Value every building, model a what-if rezoning, get alerts when a violation lands or a new-build files nearby.
SEE THE WORKFLOW →“I watch six buildings in my neighborhood for violations and new-build activity. I get an alert before the block does.”
Screen ten sites in the time it used to take to screen one. Stack every zoning scenario, run the assemblage, value the deal, track every target.
