Among the most notable actions in a busy stretch of bill signings, Ferguson signed legislation on March 27 allowing housing to be built in commercial and mixed-use zones — a measure he had specifically requested. On March 23, he signed three separate bills: one establishing rules for how businesses handle penny shortages, one banning noncompete agreements statewide, and one expanding the Washington State Traffic Safety Commission's access to data used to review fatal crashes.
Earlier in the month, on March 17, Ferguson signed Senate Bill 6084, which prohibits double voting by closing an ambiguity in existing state law. That same day, Ferguson and Oregon Governor Kotek released a joint statement reaffirming their commitment to replacing the Interstate Bridge, a 109-year-old structure that engineers warn could collapse during a major earthquake due to timber support piles sitting in loose, liquefiable sand.
On March 20, Ferguson traveled to Yakima to sign 10 bills sponsored by Republican legislators, marking the second straight year he has taken bill-signing action in Eastern Washington on Republican-led legislation. Ferguson had commented on the conclusion of the 2026 legislative session on March 12.
