One county-wide November 16 deadline

LaSalle County Assessment Publications posts a county-wide banner: the deadline for ALL 2026 assessment appeals is Monday, November 16, 2026. Newspaper publication date for the listed townships is Friday, October 9, 2026. The Appeal Form still references the 30-days-after-township-publication rule — product surfaces the posted county banner date and does not invent per-township appeal dates.
