What can you build here?
The zoning analysis you usually have to wait weeks for.
On demand.
A full architect-grade feasibility study for any NYC building or assemblage. Every legal scenario modeled, every envelope constraint computed, every tax program evaluated, every ZR citation included — with floorplan sketches and a 3D massing model. Delivered as a live, interactive web report.
No account needed for a single report. $149–$499 depending on lot size.
Inside every report
A live dashboard, not a PDF attachment.
Every report is a live web dashboard, not a static PDF. Drill into any scenario, compare programs side by side, refresh when the underlying data changes. Export to PDF when you need to share.
Property Summary
PLUTO snapshot, frontage, street widths, flood zone, landmarks, E-designations, assemblage detection — all cross-referenced automatically.
Zoning Overview
District, overlays, special-district overrides, split-zoning detection. ZR citations on every claim so you can verify the call.
Development Scenarios
Max Residential, UAP / City of Yes, IH, Community Facility, SRO, Tower-on-Base, Shared Housing, Mixed Use — each scored and ranked.
Scenario Comparison
Side-by-side table — buildable SF, unit count, FAR utilization, height, setbacks, parking — across every viable program.
3D Massing + Stacking
Interactive 3D envelope viewer + floor-by-floor breakdown with use types. Rotate, pan, inspect any floor.
Parking Analysis
Required spaces, waiver eligibility, loading-berth requirements, special-district overrides, core + curb-cut implications.
Split Zoning
When a lot straddles two districts, the engine computes the weighted envelope and shows the per-district contribution.
Affordability
MIH compliance, AMI bands, IH options, 421-a / J-51 / ICAP eligibility, tax-program stacking strategy.

The engine
Architect-level computation. Not a lookup table.
Most “zoning tools” look up the FAR for a district and call it a study. Real zoning analysis is the geometry: per-edge yard classification, sky-exposure plane in 3D, dormer allowances, special-district overrides, weighted envelopes when a lot straddles two districts. We do the geometry.
“Genuinely world-class. Split-zone weighted envelopes, anisotropic yard geometry, full Zoning Resolution and special-district interpretation, sky-exposure plane, dormer allowances, PBA detection.”
Split-zone detection
Weighted FAR + envelope across two zoning districts.
Anisotropic yard geometry
Per-edge classification (front / side / rear) via DCM street polylines.
Sky-exposure plane
True 3D plane + base-height + setback envelope per ZR 23-60.
PBA detection
Private road / publicly-accessible-area detection affects yards + FAR.
Special districts + overlays
MiD, HY, DB, LIC, LM and dozens more — FAR overrides applied automatically.
All 5 boroughs, 1M+ lots
Every NYC tax lot, regardless of shape or zoning complexity.
Multi-lot studies
Assemblage in one click.
Select adjacent lots; the engine computes merged zoning, combined frontage, shared yards, and per-program scenarios for the assemblage as a whole. Irregular shapes, split zoning, special districts — all handled.

Enterprise tier
Put your logo on every report.
Enterprise subscribers get unlimited general analysis on every NYC lot, plus 15 advanced architect-grade reports per account per month — all carrying your firm's logo, colors, and name on the web view and every export. Clients see your brand, not ours.
See Enterprise pricingCommon questions
How long does a report take?
On demand. Assemblages of 10+ lots take a touch longer.
What if my lot is split across two zoning districts?
Handled automatically. The engine detects the split, computes weighted FAR, and generates per-district contributions for the envelope.
Do I need an account to run one report?
No. The a-la-carte path is the only module you can buy without an account. $149 for lots up to 6,999 SF, $349 up to 69,999 SF, $499 above.
What's NOT inside the report?
Dollar valuation and comparable sales live in separate tools (Valuation and Comparables). The report tells you what you can build — the valuation tool tells you what it's worth.
Can I export to PDF?
Yes, anytime. But the primary experience is the live web dashboard — you can return to it, drill in, and filter scenarios. PDF is for sharing.
Does it cover all 5 boroughs?
Every NYC tax lot — Manhattan, Brooklyn, Queens, Bronx, Staten Island. Over 1 million lots.
How do credits work on Enterprise?
Each account gets 15 advanced unlocks per month, pooled across all 3 seats (not per-seat). One credit unlocks the full architect-grade study for a single building or assemblage. Refreshes and re-runs on the same building are free for the rest of the cycle. Overages run each.
Can I share my login with my team?
No. Each seat is licensed to one person. Add seats from your admin dashboard.
Can I run a report for a colleague at another firm?
No — each Enterprise account is for properties and projects within your own business. If a colleague at another firm needs a report, refer them to our à la carte option ($149).
What happens if I switch laptops?
Revoke the old device from your settings, then register the new one on next sign-in. There is a 1 hour cooldown after revoking to prevent rapid swap abuse.
