It depends where you are looking.  IN a town you would search for a casa independente - but that doesnt necessarily mean its detached.   IN the countryside it could be a casale, casa, casa rurale, - it all depends on how the site you are using classifies the houses.   Idealista for example does not have a detached house category and nor does immobiliare.it   Terms vary with location too. A rustico in some parts of Italy means a detached house in the country, in others it means a half built house.

Okay, that sums up what I had suspected, that we pretty much need to filter by general category, but then look home by home.  I guess this is really not any different from what I saw in the U.S., but it is odd to me.  It is a significant and clear criteria, but it gets mishandled often.

By the way I found some filtering on Idealista.  On the "Homes" filter, hit the down arrow and it expands to more sub-choices.  One is "Detached", but again, this still leaves more than a few that are attached.

That is quirky.  Should make for interesting shopping.
