What happens next
It reached the Governor's desk on September 10, 2026. Bills presented after the Legislature adjourned on August 31 must be signed or vetoed within thirty days.
The Governor can sign the bill, veto it, or let it become law without a signature. Until the decision, sign and veto request letters are the remaining channel, and the Department of Finance's enrolled bill report carries weight on anything with a fiscal effect. If signed, most provisions take effect January 1, and implementation moves to the agencies named in the bill.
What it means for housing organizations
Two decisions follow from a bill at this stage. The first is whether to weigh in with the Governor's office before the thirty-day window closes. The second is how to prepare for implementation if it becomes law: which agency writes the rules, when the comment period opens, and which obligations begin January 1.
The housing group at Capitol Axis handles that for housing clients.
