2026 General Election · Tuesday, November 3, 2026

St. Joseph County Assessor

Voted on across St. Joseph County.

What this office does

The county assessor is an elected county officer who oversees the valuation of property for property taxes across the county. The assessor equalizes assessments countywide, certifies gross assessments to the county auditor, finds omitted property and, in most townships, does the assessing directly [1]. Every Indiana county elects its assessor in 2026 [2].

The job in full — the duties the Indiana Code puts in it, the term, what it pays and who sets that, and what to ask a candidate.

Term
4 years [3]
Term limit
None; the assessor is not one of the offices limited by Article 6, Section 2 [4]
Qualifications
Must have lived in the county for one year before the election and own real property in the county on taking office; must hold a level two assessor-appraiser certification before a first term, and level three if previously the county assessor [2, 3]
Pay and staff

What the law puts in this job (4)
  • Equalizes assessments across the county and certifies gross assessments to the county auditor [1].
  • Discovers and assesses omitted property [1].
  • Assesses property in every township that does not have its own elected, qualified township assessor [1, 8].
  • Does not set tax rates or levies; those are set by the local governing bodies and reviewed by the Department of Local Government Finance [9].

Measured, for this county

Ratio-study figures are county-wide numbers computed by Legal Insights' county study from the 2025 ratio study, not DLGF's official township statistics. A position compares this county with counties of similar size. It is not a grade: for most measures a higher or lower number is neither good nor bad on its own.

Median assessment ratio, homes · 2026

0.902

Assessed value divided by sale price for homes that sold; the middle value. 1.00 means assessments equal sale prices.

How much this is the officeholder's to decide: high: the assessor and the assessor's vendor set values; DLGF reviews and approves the ratio study

Position 11 of 11 counties with 150,000 or more residents that have this figure (1 = highest value)

source

Assessment uniformity (COD) · 2026

9.89

Coefficient of dispersion: lower means similar homes are assessed more evenly. The IAAO residential standard is 15 or less; DLGF applies it township by township, so a county-wide figure is context.

How much this is the officeholder's to decide: high: the assessor and the assessor's vendor set values; DLGF reviews and approves the ratio study

Position 4 of 11 counties with 150,000 or more residents that have this figure (1 = highest value)

Price-related differential (PRD) · 2026

1.003

Whether lower- and higher-priced homes are assessed at the same ratio; the IAAO range is 0.98 to 1.03.

How much this is the officeholder's to decide: high: the assessor and the assessor's vendor set values; DLGF reviews and approves the ratio study

Position 7 of 10 counties with 150,000 or more residents that have this figure (1 = highest value)

Home sales used in the ratio study · 2026

1,222

How many sales the study could use; fewer sales make the other figures less certain.

Context, not something the officeholder sets: number of sales in the market, not an assessor choice

Position 11 of 11 counties with 150,000 or more residents that have this figure (1 = highest value)

Net assessed value growth · pay2024-pay2026

+17.2%

Change in the county's net assessed value from taxes payable in 2024 to 2026.

How much this is the officeholder's to decide: low: mostly market prices, new construction and state law; the assessor applies them
