Zoning, explained in plain English. See what’s allowed, what’s not, and whether a property has real upside — in seconds.
Most zoning research takes hours of digging through government websites. Zonescore gives you the three things every real estate decision starts with.
Permitted uses, ADU rights, STR status, duplex and multifamily eligibility — color-coded and tappable.
Height limits, FAR, minimum lot sizes, and coverage maximums pulled from the official zoning ordinance.
Stability and Opportunity scores show you how likely the zone is to hold — and what it could support.
The free lookup answers “what can I build here?” Zoe answers “where can I build this?” — every district in a county that allows a use, with the section that says so.
Data sourced directly from city and county zoning APIs, GIS layers, and parcel databases — not scraped aggregators.
Every market records the exact ordinance edition and data date it was built from, and publishes them with the answers. A newer edition is re-extracted and re-verified before it ships.
Every result links to the jurisdiction’s official zoning source so you can check it yourself before you act.
Decision advantage in real estate. Now available to everyone.
Know what you — and your future neighbors — can build before you close. Understand how zoning affects resale value and long-term potential.
Screen deals in seconds. Instantly surface ADU rights, STR eligibility, density potential, and comp-plan alignment before you spend time underwriting.
Embed Zonescore in any listing page. Deliver instant zoning clarity to your buyers — a signal that separates you from every other agent in the room.
Most buyers, sellers, and investors make decisions without ever reading the zoning code. Zonescore closes that gap.
Zoning and other land-use controls “play the dominant role in making housing expensive.”
Glaeser & Gyourko — “The Impact of Zoning on Housing Affordability,” NBER WP 8835 (2002)“Zoning may be more important than either geography or transportation networks… in explaining where commercial and industrial activity are located.”
