Powering your GIS decisions with better data
Still relying on outdated, misaligned data and telling yourself it’s “good enough”? That’s like driving blindfolded around a curve and hoping for the best. You wouldn’t do that—and you don’t have to with your GIS data, either.
Backed by decades of GIS mapping, data collection, and standardization expertise, ParcelQuest delivers the most authoritative, continuously updated California parcel boundaries, owner names, addresses, and characteristics directly into your GIS environment.
Features
Standardized Zoning Information Across City and County Lines
Gathering current zoning data from more than 500 municipalities across California is impressive on its own. But the real magic happens when that chaos is transformed into accurate, parcel-level zoning for all 13+ million parcels statewide and kept continuously up to date.
The PQ GIS team starts by overlaying every available zoning layer onto our daily-updated parcel base, resolving misalignments and inconsistencies along the way. Our team then interprets and applies every applicable zoning code to each parcel with precision. When GIS data doesn’t exist, we roll up our sleeves and manually assign zoning directly from source documents.
The result? A clean, statewide zoning layer that clearly defines boundaries and intent. All parcel level zoning codes, zoning descriptions, and associated zoning jurisdictions are then delivered seamlessly inside ParcelQuest Gateway, turning one of the most complex datasets in California into something powerful, reliable, and easy to use.
