Yorkville Property Assessment Update Sets Timeline for Resident Tax Notices From September 2026
Yorkville property owners will receive revised assessment notices starting in September 2026, with adjusted tax bills scheduled for the January 2027 collection cycle under the mayor's office implementation plan.
How we reported this
The Yorkville mayor's office released the rollout schedule for revised property assessment procedures on July 7. The changes apply to all 45,000 residential properties inside city boundaries. Assessment notices will begin arriving by mail on September 15, 2026, and will form the basis for 2027 tax statements issued by the municipal finance department.
City council approved the underlying assessment alignment measure in December 2025 to match updated regional housing value records collected through the end of 2025. The municipal budget documents list $2.3 million for the project within the 2026 operating budget. This step follows two years of recorded shifts in local sale prices tracked by the assessment office.
Effects on Household Costs and Local Services
Owners of single-family homes in the Riverside and West End districts will see the first concrete changes when the notices arrive. Renters in multi-unit buildings on Main Street may encounter follow-on adjustments if property owners recalculate lease amounts after receiving the new figures. The city finance office projects an average 4 percent shift in annual tax liability for detached homes based on the 2025 market data incorporated into the process.
Small businesses along Yorkville Avenue will receive parallel notices in the same September window. Those updated valuations will affect commercial tax payments due in the first quarter of 2027. Public works crews will continue routine road and park maintenance on the existing schedule, unaffected by the assessment timeline.
Remaining Phases Through 2027
Property owners can file appeals beginning October 1, 2026, with the assessment review board required to issue decisions by December 15. The full set of revised values will feed into the March 2027 tax billing cycle, according to the city clerk's public records. Staff from the assessment office will hold information sessions at the Yorkville Public Library on August 10, 17 and 24 to walk residents through the notice format and appeal steps.
