How many Grantsville homes look over-assessed?
We analysed 4,140 single-family homes and condominiums with a Grantsville address that carry enough detail to compare against neighbours — an assessed value, a building area, and a named subdivision. They sit across 134 subdivisions.
1,503 of them — 36.3% — are assessed more than 5% above the median of comparable homes in their own subdivision, once building size is accounted for. Of those, 1,099 are more than 10% above.

"Grantsville" here is the address city as the county records it, which follows postal rather than municipal boundaries — a few of these parcels may sit outside the city limits.
The largest subdivisions in Grantsville
Comparisons are made within a subdivision, because that is the group an assessor values together. These are the largest ones here.
| Subdivision | Homes analysed | More than 5% above median |
|---|---|---|
| (None) | 1,015 | 585 (57.6%) |
| South Willow Est Amd Plat 1 | 134 | 47 (35.1%) |
| Old Church Sub | 77 | 27 (35.1%) |
| South Willow Estates Ph 4 | 77 | 23 (29.9%) |
| Park Meadows Sub | 75 | 18 (24.0%) |
Subdivision names appear exactly as Tooele County records them, abbreviations and plat numbers included — so "Amd" for amended, "Add" for addition, "Ph" or "#2" for a phase. We do not tidy them up, because the name is what you would search for in the county's own records to check a comparable.
What is the 2026 appeal deadline for Grantsville?
Grantsville property is assessed by Tooele County, so the appeal is filed with the county rather than the city. 15 September 2026, or 45 days after your valuation notice — whichever is later.
The later of September 15, or the last day of a 45-day period beginning the day the county auditor provides the valuation notice (Utah Code 59-2-1004(3)(a)).
The application goes to County Auditor.
Can a Grantsville homeowner appeal on comparable assessments?
Equalization Ground Accepted
Yes. UT treats equalization — how your assessment compares with comparable properties — as a ground in its own right, separate from arguing what the home would sell for.
UT is a non-disclosure state: sale prices are not public record. That is why comparing assessed values is the practical route — assessed values are published for every parcel, and sale prices are not published at all.

The figures above are the roll in aggregate. For one property we show its own comparable homes, each with its parcel number so it can be checked against Tooele County's records.
