As far as I know, there are no rules regarding the drainage of rainwater inside the house.
However, it is important to remember that runoff and rainwater should be separated inside the house so that it drains independently to the outside.
Most importantly, a second drain or overflow should be provided in case the existing drain does not work properly.
