Bannock County board adjusts multiple property assessments after appeal hearings

Bannock County commissioners, sitting as the Board of Equalization, adjusted several property assessments after hearing appeals from homeowners and reviewing evidence presented by the assessor’s office.

The board opened the formal hearing by reminding appellants of the burden of proof under Idaho law. “According to Idaho Code 63-502, our role is confined strictly to assuring that the market value for assessment purposes of your property has been properly determined by the assessor,” said Commissioner Jeff Huff, chairman of the Board of Commissioners. He told appellants they must supply factual evidence — recent sales, professional appraisals, photographs or documentation of damage or limitations — to meet a preponderance-of-evidence standard.

Commissioners heard separate appeals from multiple property owners. Appellants presented sales comparables, time-adjusted sale prices, acreage corrections and evidence about easements, drainage and unfinished interior space. County staff and assessor’s office representatives responded with their sales analyses, time adjustments to the valuation date of Jan. 1 and recommendations. After brief discussion in each case, the board voted to adopt adjusted values or accept purchase prices as described below.

Why it matters: Local property assessments determine tax bills and can affect owners’ decisions to sell, refinance or invest in property. The board’s role is limited to whether the assessor correctly determined market value as of Jan. 1; the board does not set tax rates.

Key decisions and reasoning

- Parcel RPR4013049517: The assessor corrected the parcel acreage after the appellant noted the assessor’s record listed 8.72 acres but the appellant’s deed and evidence showed 2.57 acres. The assessor’s office recommended an adjusted land value and a revised total assessed value. The board approved the adjusted assessed value as moved on the record (motion text recorded by the clerk) and the motion passed by voice vote. The board said the correction addressed the appellant’s primary concern about acreage and that the revised per-acre values were consistent with neighboring parcels as analyzed by staff.

- Parcel RP...000400 (appellant Emily Stark): Stark argued her lot, along Highway 91 near a frontage road, should be valued lower than the assessor’s figure based on recent sales in the immediate area and concerns about runoff and highway frontage. The assessor said several listed comparables were verified sales and time-adjusted to Jan. 1; staff recommended upholding the assessment. One commissioner moved to reduce to $75,000 based on pending sales, but the board instead accepted the appellant’s documented purchase price of $80,053 (motion passed by voice vote).

- Parcel RPRCH E1000300 (appellant Amber Anderson): The purchaser said the house sold in August 2024 for $495,000 and objected to a higher assessed value the assessor produced using mass-appraisal formulas. The assessor described the ratio study and time adjustments used to convert sale prices to the Jan. 1 valuation date and said the mass appraisal results fell within statutory tolerance. The board applied a modest time adjustment and approved an assessed value of $509,850, with the reduction taken from improvement value.

- Parcel RP R P C P P O...010500 (appellant Jessica Watson): Watson presented evidence about a sewer easement that she said reduced usable acreage and cited a prior purchase price and recent sales. The assessor presented three comparable sales in the same subdivision and noted they were bare land sales time-adjusted to Jan. 1. The board concluded the appellant met the burden for a lower value than initially assessed and approved an adjusted assessment of $90,000.

- Parcel RPRRPEP000100 (appellants Patrick/Pat McCullough): The appellants argued that assessor records incorrectly counted unfinished or accessory space (a storage/bonus area above the garage) as finished living area; they also raised concerns about comparables and the rate of increase in assessed values. The assessor’s office agreed to re-inspect and reclassify the space if it is not accessible from the house and therefore not above-grade finished living area. After staff costed adjustments, the board adopted an adjusted total assessed value of $714,138.37, with the reduction coming off the improvement value.

What commissioners and staff said

Commissioner Jeff Huff, chair: “We are not here to discuss taxes. … Under Idaho law, you as the taxpayer have the burden of proof when seeking to change your assessment.” (board opening remarks)

Assessor’s office (staff, identified in the hearing as Miss Sesser and other office representatives) described the county’s use of a ratio study and mass-appraisal process to time-adjust sale prices to Jan. 1 and explained how land value allocations (a higher value for the first acre, lower for additional acres) were applied in the county’s market analysis.

Appellants raised factual evidence used in appeals: corrected acreage, closing statements and purchase prices, comparables time-adjusted to the valuation date, easements and drainage issues, and the presence or absence of hookups (sewer, power) on comparable lots.

Next steps and appeals rights

The board’s decisions are the Board of Equalization’s determinations for the assessment year in question; appellants were told they will receive written notices explaining the decisions and that further appeals may be filed to district court or the state board of tax appeals, as allowed by law.

Ending

Letters summarizing each decision will be mailed to appellants. Commissioners said assessor staff will follow up on re-inspections where measurement or classification questions remain (for example, the contested space over one garage). The Board adjourned after the scheduled appeals.
