text: No. I think going into a woman's restroom in itself isn't against the laws of any state. It's what you do in there which could constitute a breach of legality. Otherwise, how would janitors be able to clean it.\n\nSuppose you accidently went into the ladies' room and quickly left when you realized your mistake. No harm, no foul.\n\nNow what if you went into the ladies' room, peeked into a stall ? Then you've broken the law. Or if you just went in, used the toilet, exposing yourself knowing that women were probably watching. Here again, you've broken the law.\n\nNow what if the men's room were broken and you had to use the ladies' room. If it was a restroom with a lock, there's probably no law. You gotta take care of business.
