You can search the MLS, with accurate, up to date listings, on my website, with no sign up: http://www.davidbarrhomes.com/sarasota_mls
The closest thing we have is on an advanced local MLS search : exterior features= detached inlaw apt,. and there just aren't that many properties in our area with that feature.
I can set up a search for you with your criteria if you'd like some help.
