Okay, I did a Google image search, and it seems the American word for this is "duplex".

Although, with more searching, it seems that "semi-detached home" refers to one living space, not the whole building, and that the semi-detached home is owned, not rented, so a more equivalent term may be "(half of a) two-family condominium".
