Summit County GIS maps parcels, zoning and development data
Summit County’s GIS maps help buyers, owners and builders check parcel lines, zoning and nearby development before a deal gets expensive.
A Park City buyer, a Kamas landowner, or a small builder in Coalville can lose money fast if a parcel line or zoning district is off by even a small amount. Summit County’s GIS tools are built to answer the questions that decide whether a property works for a purchase, a permit, or a development deal: where the parcel sits, what code applies, and what else is mapped around it. The county’s property and planning pages pull those answers into one public toolkit.
What Summit County GIS actually gives you
Summit County GIS is a mapping and geographic-data service that provides spatial analysis tools, property information, zoning maps, and other resources for planning and development in Summit County, Utah. It is the county’s public-facing layer system for understanding how land is organized on the ground, from roads and subdivisions to zoning and property context.
One county parcel reference map includes separate layers for roads, cities, subdivisions and parcels at multiple scales. Another county map service, EB - Parcel Web Map, adds parcel proportional layers, a parcel heat map, market value of land and community-related overlays. The county’s Property Page ties those tools together with links to an Assessor Values Map, County Road Map, Parcel Map, Zoning Map, PLSS Tie Sheets and a Wildfire Risk Assessment map.
A property can be compared against road access, neighboring subdivisions, city boundaries, assessed land value and wildfire exposure before anyone commits to a purchase price or starts a design.
Why zoning depends on the exact place
Land use in Summit County is regulated through development plans, development codes, zoning regulations and development agreements. The county has two planning districts: the Snyderville Basin Planning District and the Eastern Summit County Planning District.
Properties in Snyderville Basin, the unincorporated area surrounding Park City Municipal, are regulated by the Snyderville Basin Development Code. Properties in Eastern Summit County, the unincorporated area surrounding Henefer, Coalville, Oakley, Kamas and Francis, are regulated by the Eastern Summit County Development Code. In practical terms, the same kind of lot can face different rules depending on whether it sits near Park City or farther east in the county.
The recorder’s records show what is on file, while the map layers show where a parcel sits in relation to the county’s districts, roads and neighboring land uses.
What to check before you buy, build or apply
The county’s map tools answer the everyday questions that drive financial decisions. If you are looking at a lot in Park City or a parcel outside Coalville, the county’s parcel map and zoning map help confirm whether the land is actually where the seller says it is and which rules apply to it. The road map and PLSS tie sheets add a second layer of verification for location and alignment.
The Assessor Values Map and the EB parcel layers also help you think about price. A parcel heat map and market value of land overlay can show how a property sits within broader value patterns, which is useful when a listing seems out of step with surrounding land. The Wildfire Risk Assessment map adds another practical filter in a mountain county where hazard exposure can affect insurance, financing and development costs.
On the recorder / surveyor search page, parcel-number indexing begins on January 1, 2001. That gives title work, property histories and archival searches a clear cutoff, which is useful when a parcel has changed hands or been subdivided over time.
How planning updates change the value of the maps
Summit County is updating both of its General Plans, and Utah state law requires a general plan. The plan must include land use, transportation and traffic circulation, water use and preservation, resource management for public lands and moderate-income housing.
The county’s code page is current through Ordinance 981, passed July 10, 2024. As plans change and development code is adjusted, the GIS layers help residents, agents and small developers see how a parcel fits into the rules now, and how it may fit into the next version of those rules.
How Summit County fits into Utah’s wider GIS system
Summit County’s parcel information is not isolated from the rest of the state. County parcel and assessment data support public safety, economic development, transportation, planning and public services. The state GIS portal also identifies Summit County parcel boundaries as authoritative parcel data within the broader Utah system.
Summit County’s parcels feed into planning, emergency response, infrastructure and economic decisions that extend beyond one property line.
