This tool helps taxpayers and policymakers better understand property assessment in Utah, allowing anyone to examine property values across the State based on various metrics. By default, the tool shows the percent change in year—over-year property values on a parcel-by-parcel basis.

We believe the quality of public data improves as it is used. We also believe in transparency — connecting citizens with their data — to improve oversight, increase accountability, and ultimately provide a better understand of Utah’s real property tax system. (Real property includes land and buildings.) This tool brings together these elements.

We compiled property assessment data from county assessors and integrated it into this unified property valuation tool. The underlying data comes directly from county assessors. We added standardized property types and tax exemption classifications to improve searchability but included original parcel description information.

Explore the map by clicking and dragging your mouse cursor. To quickly find a specific parcel, simply click the Search button (the magnify glass icon in upper right corner of map), then enter the desired street address.

A huge thank you to all the county assessors who promptly shared their data, provided valuable feedback, and collaboration in developing this innovative tool.

We also express appreciation to our colleagues at the Utah Geographic Resource Center for their advice and help in developing this GIS-based tool.

Default Map

The default map shows the percent change in year-over-year property values. As an example, assume a parcel was valued at $500,000 in 2022 and increased in value to $625,000 in 2023 — an increase of 25%. The tool would visually display this significant increase in value. Conversely, assume a parcel was valued at $625,000 in 2022 decreased in value to $500,000 in 2023 — a decrease of 25%. The tool would visually display this significant decreased. And the tool does this on a parcel-by-parcel basis.

Map Legend

• Red: Property value increased (the darker the red denotes the greater the increase in the percent change in value)
• White: Minimal change in property value
• Blue: Property value decreased (the darker blue denotes the greater the decrease in the percent change in value)

Other Maps

Other maps are available. Click on the cube-shaped icon shaped (looks like it is sliced horizontally, called "Layers") to view all the available maps in the tool. Each map may be enabled by clicking the "eyeball" icon next to the specific name.

• Tax Exempt Properties — Parcels colored dark grey are tax exempt properties (such as churches or government buildings). This map shares available information for tax-exempt parcels.
• 2023 Market Value — The assessed market value of parcels are displayed. The assessed market value of a parcel is shown on scale from 0 being white with $2,000,000+ being the darkest shade of red.
• Property Types — This layer shows various standardized property classifications. Each county has unique classifications, but most can be standardized. For example, one county might use the word "Residential Property" another might use "Residential Prop" and another might use "Res Prop". We classified these as "Residential".

2023 Tax Year Data was submitted shortly after the May 22nd tax rolls were closed. This assessment data is subject to change, such as based on a successful appeal. Data shown in this tool is a "snapshot" in time and will change as updated. Checking the "Date Data Received From County" field allows you to see the date we received the property value information. We anticipate updating this data twice each year (before and after the board of equalization process).

The "Detailed Property Review Date" is the date when an assessor last reviewed a parcel in detail. Depending on the county, this may involve an in-person visit, a remodel or other new improvement, or the use of aerial imagery to assess a parcel. Important Note: Counties treat this field differently, so comparing this field across counties is discouraged.
