In reality there is no way to keep a plant from not growing taller than
it is designed to.
The best thing you can do is have it moved, though it could be to large
to move ans the only thing you can do is cut it down and use it for
firewood.
My personal pereference is that you should never plant trees next to a
house.

Don't cut it down. The OP said it is only 3 feet tall. You can easily
transplant a tree that size. I don't think there are any varieties of
Japanese maples that will stop growing at 3 feet. If it is a dwarf variety,
you may have to resort to bonsai techniques to keep it that small.
