Is it illegal for three people to live in a standard hotel room?

It's not illegal. Let's deal with it strictly. Big cities are definitely stricter than small cities, and the downtown is definitely stricter than the suburbs. According to the strict management system, it is not allowed to live more than the specified number. Living in too many people will be a safety hazard. According to the regulations of the fire department, the per capita area of hotel rooms needs to be above a certain number. I forgot the specific data, so a standard room in a hotel of average size is only enough for two people. There are too many people, and when there is a fire, there will be shoving and trampling. In areas with strict management, hotels will be punished if they find guests who are out of scope. 500 yuan fined, according to the anti-terrorism law, the minimum fine was tens of thousands, which brought serious trouble to the hotel. I hope everyone will not only care about themselves, but also consider others.
