Idaho Senate Passes Bill Criminalizing Use of Public Bathrooms Not Matching Biological Sex
BOISE, Idaho — The Idaho Senate passed legislation Friday that would criminalize the use of public restrooms that do not match an individual’s biological sex, sending House Bill 752 to Governor Brad Little’s desk for his signature. If signed into law, the measure would mark a significant expansion of Idaho’s existing transgender bathroom restrictions and represent one of the more far-reaching pieces of legislation to emerge from the 2026 Idaho legislative session.
The bill’s passage adds Idaho to a growing list of states moving to codify biological sex-based restroom access policies into law, a trend that has generated intense national debate over the past several years. For Bannock County residents and communities across Southeast Idaho, the legislation would have practical implications for enforcement in public facilities ranging from government buildings and parks to retail establishments and restaurants.
What House Bill 752 Would Do
House Bill 752 builds upon a 2023 Idaho law that required schools to regulate bathroom and locker room access based on students’ biological sex. That earlier measure focused specifically on educational settings. The new legislation extends criminal penalties to public restroom use broadly, meaning the restriction would apply across a much wider range of publicly accessible facilities throughout Idaho, including those in Pocatello, Chubbuck, Inkom, Lava Hot Springs, and communities across Bannock County.
Under the proposed law, individuals who use a public restroom that does not correspond to their biological sex could face criminal charges. The bill passed the Idaho Senate on Friday morning and now awaits action from Governor Little. The governor’s office had not publicly announced a position on the bill as of Friday afternoon.
Supporters of the legislation argue the measure is necessary to protect privacy and safety in intimate public spaces, particularly for women and children. Proponents have framed the bill as a commonsense protection that reflects the values of the majority of Idaho residents, who they say support clear, biological definitions of sex in public policy.
Opponents have countered that the bill is unenforceable, discriminatory, and harmful to transgender Idahoans, arguing it would expose a vulnerable population to harassment and legal jeopardy simply for using a restroom. Civil liberties organizations have indicated they may mount legal challenges should the bill be signed into law.
Legislative Context and the Path to the Governor’s Desk
The passage of House Bill 752 through the Idaho Senate reflects the conservative direction of Idaho’s Republican-dominated legislature in recent sessions. Idaho lawmakers have addressed a range of social policy issues in 2026, including legislation related to disability housing funding and ongoing debate over medical marijuana legalization, signaling an active session on both fiscal and social fronts.
The bathroom bill had already cleared the Idaho House before advancing to the Senate, where it passed Friday. The measure’s path through the legislature was relatively straightforward given the Republican supermajority that controls both chambers. GOP legislators in Idaho have consistently argued that state law should reflect what they describe as biological and scientific definitions of sex, particularly in settings where privacy is at a premium.
For Idaho State University and other public institutions in Bannock County, the bill’s potential signing raises administrative questions about compliance, signage, and enforcement — areas where public entities would likely need to develop internal policies to align with state law.
The broader debate over this type of legislation continues at the national level, with similar laws having been passed or attempted in several other states. Courts have issued mixed rulings on comparable measures, and legal experts expect challenges to Idaho’s law if it is enacted.
Governor Little, a Republican who has signed a range of conservative social legislation during his tenure, has not publicly stated whether he intends to sign House Bill 752. He has until the constitutional deadline to act on the bill.
What Comes Next
The legislation now sits with Governor Brad Little, who can sign the bill into law, allow it to become law without his signature, or veto it. If signed, the law would represent one of Idaho’s broadest restrictions on restroom access to date and would likely face immediate legal scrutiny.
