Homeowner cites radon, unpermitted work and siding damage in challenge to Pleasant Prairie assessment; board sustains value

Tatiana Zarkarchenko appeared before the Pleasant Prairie Board of Review on July 14 to contest the village’s 2026 assessment of her home at 8942 106th Avenue. Zarkarchenko told the board she purchased the house for $599,500 on Oct. 30, 2025, and asked that the assessment be reduced to $510,000, arguing the assessor relied improperly on her purchase price and MLS advertising rather than village permit records.

Zarkarchenko said a February 2023 appraisal and a subsequent home-inspection record showed the basement was not a permitted finished living area and that a radon test taken during purchase registered hazardous levels. She also produced an Infinity exterior siding estimate for about $23,073 and claimed the assessor’s property record included a premium plumbing item that does not exist at her home.

Elizabeth Baker of the assessor’s office responded that staff had attempted two property-view inspections and relied on the best available information where access was not granted, including the MLS floor plan and photographs. The assessor explained the office’s valuation for 2026 reflected neighborhood sales, a finished‑basement adjustment based on MLS evidence, and time adjustments from sales covering 2024–25.

Board members questioned whether the radon test or the siding estimate were dispositive; the assessor said the lender did not require mitigation and that the siding matter and the home‑inspection report had not been fully shared with the office for verification. After deliberation the board voted to sustain the assessor’s valuation; the clerk will provide a notice of determination that explains appeal options.

Zarkarchenko’s claims raised two notable points for future appeal: (1) she displayed a contractor estimate for siding repairs and (2) she reported a radon test result that she said renders part of the basement unsafe as living space. The board’s decision rested on the evidence and comparables presented in the hearing record; owners who wish to pursue the matter further were advised how to file an appeal per the notice of determination.
