SB 428 Wisconsin Senate · 2025-2026 Regular Session

Relating to: county public works notice and competitive bidding thresholds. (FE)

SB 428 raises county public works bidding and notice thresholds in Wisconsin. It increases the bidding threshold from $25,000 to $50,000 for competitive bidding and the notice threshold from $5,000 to $10,000 for public notice requirements. The bill also creates an automatic inflation adjustment: every 5 years, these thresholds will increase based on the U.S. consumer price index, rounded to the nearest $1,000. This affects counties and contractors handling public construction projects, requiring them to follow these updated cost-based bidding rules for most projects over the new thresholds.
