Residential can get it too. They changed that a few years ago.
However, for any rental, it must rise to the level of a "Trade or Business" in order to qualify for Section 179.
I have no idea how ProConnect works, but in ProSeries the 4562 income limit (line 11) automatically assumes the rental does NOT rise to the level of a Trade or Business. So if it DOES rise to that level, you need to manually change line 11 on the 4562.
