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.
Data sourced directly from city and county zoning APIs, GIS layers, and parcel databases — not scraped aggregators.
Our data sources are monitored continuously so what you see reflects current zoning, not last year’s snapshot.
Every result links to curated official sources so you can verify before you act — one click to the ordinance.
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.

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.”
