Residents of Granite County can explore parcel shapes, owner names, tax status and land‑use codes through the county’s online portal. By typing an address or tax ID into the search box, the system returns the exact lot outline, market value, and any outstanding taxes. The map engine layers streets, rivers, zoning districts and flood zones so users see a full picture of each property. The portal also hosts downloadable PDFs that list the current tax bill, assessment methodology and exemption criteria. All data updates automatically when the assessor’s office files a new record.
The platform links directly to Granite County GIS maps that show every parcel boundary. Users can turn on the “real‑estate GIS” layer to view recent sales prices, while the “land‑assessment” layer displays the latest assessed value for each lot. The parcel viewer works on desktop and mobile browsers, making it easy to check a property while on the road.
Property Search Tool Overview
What the Granite County Property Search Tool does
The tool matches an input address, parcel number or owner name with the county’s GIS database. Results appear as a highlighted polygon on an interactive map, plus a table that lists:
- Parcel ID
- Owner name
- Assessed value
- Land‑use code
- Current tax amount
Users can download the table as a CSV file for further analysis.
Cost of using the search tool
Access is free for anyone with an internet connection. No registration or payment is required to view parcels or download basic reports.
Database refresh schedule
New assessments, deed recordings and tax payments are entered nightly. The public map reflects those changes within 24 hours, ensuring that the information is current.
Partial address or owner searches
Typing only the street name, a portion of the owner’s last name or the first three digits of a parcel ID returns a list of possible matches. Users can then select the correct entry from the drop‑down menu.
When a property does not appear
Missing parcels usually belong to one of three categories:
- Newly subdivided land that has not yet received a parcel number.
- Properties owned by the state or federal government, which are recorded under a separate agency.
- Records that contain a data entry error.
In those cases, contact the office using the information in the “Contact Block” below.

Property Tax Estimator Details
How the estimator works
The estimator pulls the most recent assessment, applies the current mill rate and adds any special district fees. The result shows the projected tax bill for the upcoming fiscal year.
Coverage for all property types
Residential, commercial, agricultural and vacant land parcels are all accepted. The tool reads the land‑use code to apply the correct exemption rate.
Accuracy of the displayed amount
The figure is an estimate based on the latest data. Final tax bills may differ if a reassessment occurs after the estimate is generated.
Comparing estimates across years
Users can select a previous year from a drop‑down list. The system then displays side‑by‑side values, highlighting any increase or decrease.
Understanding the County Tax Roll
Definition of the tax roll
The tax roll is a master list of every taxable parcel, its assessed value and the amount owed for a given fiscal year.
Responsibility for preparation
The Assessor’s Office compiles the roll. After the assessment cycle ends, the Treasurer’s Office finalizes the numbers and publishes the roll.
Annual finalization date
Each year the roll is locked on October 15. After that date no changes are made for the current fiscal year.
Access to historic rolls
PDF copies of rolls from 2018 to the present are available on the county website. Users can download the file that matches the year they need.
Why historic rolls matter
Reviewing past rolls helps owners track value trends, supports appeals and assists researchers studying market changes.
Primary Residence Tax Classification
What the classification means
Properties classified as a primary residence receive a 30 % reduction in the assessed value. The reduction lowers the annual tax bill.
Eligibility criteria
- The owner must occupy the property as their main home.
- Ownership must be recorded in the county’s deed database.
- The owner cannot claim the same exemption on another property.
Application process
Applicants submit a short form with proof of residency, such as a driver’s license, utility bill or voter‑registration card. The form can be mailed or uploaded through the online portal.
Online Application
- Visit the Assessor’s website.
- Select “Primary Residence Exemption.”
- Upload required documents.
- Submit the form.
In‑Person Application
- Go to the Assessor’s Office during business hours.
- Fill out the paper form.
- Present original documents.
- Receive a receipt.
Application deadline
All requests must be filed by March 31 of the assessment year. Late filings are considered for the following year.
Impact of life changes
Changes such as marriage, divorce, or moving out of the home require a new filing. Failure to update the record can result in loss of the exemption.
General Services Provided by the Assessor
Viewing historic records online
The public portal includes a “Historical Records” tab. Users can select a year and view scanned copies of deeds, plats and previous assessments.
Appealing an assessed value
Owners have 30 days after the notice of assessment to file an appeal. The appeal form must include a recent appraisal, comparable sales data and a written statement of why the value is incorrect.
Verifying ownership
Enter a parcel ID into the search tool. The resulting page lists the current owner, mailing address and any liens recorded against the property.
Correcting inaccurate details
If a name, address or land‑use code is wrong, owners can submit a correction request. Supporting documentation, such as a court order or updated deed, speeds the process.
