The tenant rented the house in advance and will move in a month, but the residential doorman property won't let him. Can you call the police?

Because the doorman doesn't know you, it is his responsibility and power not to let you in, which shows that he has a conscience. As long as you have proper rental procedures, such as a rental contract, you can find a room east to explain the property to the community doorman, and the problem will be solved. Don't make a mountain out of a molehill by calling the police. You won't get along with the doorman in the future.
