HB 485 Montana House · 2025 Regular Session

Revise residential home construction contract laws

HB 485 sought to revise residential home construction contract laws. It proposed that an accepted bid in a residential home construction contract would constitute the total amount to be paid. This means a contractor could not increase the bid amount after it was accepted. However, this provision would not apply if the parties agreed in writing, before bid acceptance, that the bid was not the final amount. This bill would directly affect homeowners and contractors involved in residential construction agreements.
