Residents press county over large, uneven assessment increases; assessor outlines valuation process

Humboldt County supervisors spent a large portion of a regular meeting hearing public complaints about sharply higher property assessments and a presentation from the county assessor outlining how values were set and what options property owners have to challenge them.

Residents told the board their assessments jumped by tens or hundreds of thousands of dollars in some cases while neighboring parcels saw smaller changes or declines. “I wanna be treated fairly, and that’s all,” said resident Richard Olsen, who said his business assessment rose about $100,000 this year while some nearby commercial properties fell in value.

Assessor Linda (Humboldt County assessor) told the board assessors use 12 months of sales data and state-produced productivity values to compute assessments, and that the Department of Revenue will apply a statewide rollback that limits how much assessed-value increases translate into taxable value. “The Department of Revenue will recalculate the rollback rate to limit … across the state to 3%,” Linda said, explaining the distinction between assessed value and taxable value and noting the county does not set tax rates.

Why this matters: Residents face higher assessed values now but the eventual change to individual tax bills depends on the state rollback percentage and next year’s levy rates. The assessor’s presentation showed agricultural productivity values and the mechanics used for residential, commercial and agricultural classes; residents asked how appeals and Board of Review or PAV (Property Assessment Appeal Board) hearings work.

Key details and county responses

- Multiple residents reported large, inconsistent assessment changes: one said a business assessment rose by about $100,000 while a nearby property decreased by $100,000; another cited a house assessed near $1.6 million though construction and market figures differed.

- Assessor Linda summarized class-level changes: agricultural values rose (she said about a 35% increase in the ag productivity-based calculation, with CSR-based rates cited moving from $25.45 to $35.50 per CSR point), an ag building factor change to 74% (meaning ag buildings are valued at about 26% of replacement cost after depreciation), and other recalibrations for residential and commercial classes.

- Sales ratio statistics presented: the assessor cited metrics including a residential median near 99.01 after revaluation, a coefficient of dispersion of roughly 25 (the assessor noted coefficients above 20 indicate potential inequities that require attention), and a price-related differential (PRD) of about 1.11; she explained what those indices mean for equality of assessments across value ranges.

- Appeals and evidence: Linda described appeal options (local board review, PAV) and said assessors must rely on available market sales; where sales are scarce, appraisals or cost/replacement analyses can be used. She urged owners to bring appraisals or allow staff to inspect interior quality when appropriate, saying, “Assessors are allowed to estimate under these circumstances. It may turn out that the estimate is wrong. And if so, then corrections can be made upon proper proof.”

- Timing and uncertainty: the assessor emphasized the county cannot predict an individual taxpayer’s final bill because levy rates and the state’s rollback calculation will determine taxable value; she said '25 assessments will affect bills payable in fall 2026 and spring 2027.'

What supervisors said and next steps

Supervisors acknowledged constituent frustration and suggested scheduling a work session with the assessor to review specific cases. Board members and staff offered to meet 1-on-1 with residents to review property record cards and identify errors; the assessor said she will accept appointments and correct obvious factual errors when supported by documentation.

The board did not take any formal action on assessments at the meeting; residents were advised to consider protests and formal appeals if they disagree with their assessments.
