Over the past 10 years, violent crime rates in Yellowstone County have increased, placing greater demands on the Yellowstone County Detention Facility and highlighting the need for expanded capacity and ongoing support for public safety. This ballot measure asks voters to approve or disapprove a permanent annual levy to fund costs of public safety services, including operating and capital costs of the Yellowstone County Sheriff’s Office and the Yellowstone County Attorney’s Office and related public safety expenses.

Levy Information

The Yellowstone County Board of County Commissioners has passed a resolution to refer this ballot measure to the voters. If approved, the measure would authorize a levy of approximately 43.35 mills to generate $20 million annually to fund public safety services, including operating and capital costs of the Yellowstone County Sheriff’s Office and the Yellowstone County Attorney’s Office and related public safety expenses, with the levy to be subject to inflation pursuant to MCA 15-10-420(1)(a). Implementation of this levy is contingent upon both voter approval and the passage of a separate, contemporaneous general obligation bond election question to fund the renovation and expansion of the detention facility.

Shall Yellowstone County, Montana (the “County”) be authorized to permanently levy approximately 43.35 mills, to generate $20 million annually, subject to 15-10-420(1)(a), MCA, for the purpose of paying costs of public safety services, including operating and capital costs of the Yellowstone County Sheriff’s Office and the Yellowstone County Attorney’s Office and related public safety expenses, provided that the Detention Facility will be expanded only if the voters also approve the separate general obligation bond?

The bond and the operations levy are two separate ballot questions with two separate mill rates. If approved, the estimated annual tax increase beginning in taxable year 2027 would be:

Home Value Bond — Construction (20-yr) Levy — Operations (Permanent)
$100,000$21$33
$300,000 (Billings median)$64$99
$600,000$136$211
Property values in Montana are determined by the Montana Department of Revenue, not Yellowstone County. Your share of the bond and levy is based on your property's taxable value relative to all other taxable property in the county. As new homes and businesses are added to the tax base, the per-property share can decrease over time. The bond and levy are independent measures; both must pass for the jail expansion to occur. An increase in property taxes may lead to an increase in rental costs.

Common Questions About the Bond

Any registered voter in Yellowstone County may vote on the bond. Montana law sets participation thresholds that determine the approval requirement: if 40% or more of registered voters cast ballots, a simple majority (50%+1) is sufficient to pass. If turnout falls between 30% and 40%, 60% approval is required. If fewer than 30% of registered voters participate, the measure is automatically rejected regardless of the vote split.
The bond will be repaid through a general obligation mill levy of approximately 32 mills on taxable property in Yellowstone County, spread over 20 years. The annual cost to property owners depends on assessed home value — approximately $23/year for a $100,000 home, $70/year for a $300,000 home, and $165/year for a $600,000 home.
The facility will continue to operate at 38% over its rated capacity. The $9.5 million in high-priority deferred maintenance — covering life safety, ADA, and code compliance issues — will still need to be addressed regardless of the bond outcome. Without expansion, population projections show the county will need approximately 892 beds by 2029, growing to 1,277 beds by 2049. Inaction does not eliminate the cost; it defers and compounds it.
Yes. The bond was authorized by Resolution No. 26-41, passed by the Yellowstone County Board of County Commissioners on March 31, 2026. The Board of County Commissioners oversees all county expenditures and is accountable to voters. The bond will be subject to annual reporting with the SEC, including providing the County ACFR and audit.
