What You Get

Kill Dead Ends Early

Prohibited use? Flood zone? Manufacturing district? ZoneLens catches fatal flaws in seconds — before you spend $500 on a zoning analysis or $2,500 on a Phase I that was never going to work.

Market-Validated Decisions

Zoning says apartments are allowed — but has anyone actually built them here? ZoneLens checks real permit data: approval timelines, denial rates, and who's already building in the zone.

Screen 200 Sites in One Session

Drop a list of addresses or browse the map. Every parcel gets instant zoning analysis, risk scoring, and a GO / REVIEW / NO-GO classification. Your team focuses only on what survives.

⏰

Minutes, Not Weeks

A typical site screening takes 15-30 minutes of manual research per parcel. ZoneLens does it in seconds. For a 50-site pipeline, that's 2 weeks of work compressed into one afternoon.

Who Uses ZoneLens

Built for people who make real estate development decisions.

Acquisitions Teams

"I screen 50+ sites a week. ZoneLens eliminated 80% of my manual zoning research and catches dead ends I used to find after spending money on title and environmental."

Lenders & Underwriters

"Before I approve a construction loan, I need to know the zoning risk is real. ZoneLens shows me the approval friction, denial rates, and whether similar projects have actually been permitted."

Land Use Attorneys

"My clients ask 'can we build X here?' and I need a fast, defensible answer. ZoneLens gives me the zoning analysis, permit precedent, and state preemption data in one place — with citations I can reference."
