The Senate has already approved its version of the bill, which expands a 2011 state law that prohibits discrimination against transgender people in the workplace and housing.
The House is expected to debate the bill on Wednesday.
The House version would allow the state attorney general to provide “guidance or regulations” to law enforcement about legal action against “any person who asserts gender identity for an improper purpose.”
Republican Gov. Charlie Baker hasn’t said whether he would sign the measure.
If the bill becomes law, Massachusetts would join 17 other states and the District of Columbia in banning discrimination against transgender people in public accommodations.
