How values are determined

Assessed value notices are ordinarily mailed annually and list the valuation date and any available exemptions or classifications.
- Sales comparison: recent nearby sales adjusted for differences.
- Cost approach: replacement cost minus physical depreciation.
- Income approach: capitalization of net operating income for rental properties.
- Exemptions and classifications: owner-occupancy, senior, or veteran exemptions when applicable.
