i was wondering if it is ilegal to have an exact model of the outside of someones house in a game without there permission. and is it ilegal to mention the street and the house number and all that stuff
This is a fairly complex issue, and it’s important to note that the advice you receive here is not legal advice. If you wish to use the likeness of a building in a game, and especially if you plan to sell the game, and you have any doubts about its legality, I suggest you contact a lawyer.
It’s also important to note that copyright laws vary by country, and by time of construction (for instance, whether the building was constructed before 1990 can have a bearing on legality).
That being said, in most cases you should be fine reproducing a building in your game, provided that a) the building is visible from a public area, and b) the building contains no copyrighted works of art. There may be other exclusions that I’m not aware of. Please see the links below for some more information:
Copyright Code, Title 17, Circular 92, § 120 . Scope of exclusive rights in architectural works (Chapter 1 - Circular 92 | U.S. Copyright Office)
(a) Pictorial Representations Permitted.—The copyright in an architectural work that has been constructed does not include the right to prevent the making, distributing, or public display of pictures, paintings, photographs, or other pictorial representations of the work, if the building in which the work is embodied is located in or ordinarily visible from a public place.

Don’t use directly the same model but try to modify as per your requirement…
