Confidence votes 14. 21. I live in Ohio and rented a hotel room for my 18th birthday. I think it just depends on the hotel, but I am still not 21 and have never had a problem renting a room anywhere in Ohio.ll hotels have their own set of rules, its not the LAW that you have to be a certain age, but most hotels choose between 18 and 21 when you can start to rent a room. 4 people found this useful.
