I’ve seen one interpretation of our fire code result in each enclosed stall requiring their own flashing light and siren. So the expense to build really does add up. Every contractor knows how to do it the cheap way, anything else they charge a much higher rate to make it worth the trouble. Maybe some shit related to sex or drug use in bathrooms as well, I’d imagine the more secure it feels the more likely someone might see that as a safe thing to try, not saying that’s a real thing but shit gets talked about on the news enough for it to be something the decision maker has in their head to be influenced one way.
