I am not seeing any granny units for Clovis in MLS. There are 4 listings in Fresno. If you would like to contact me, I can help setup a search to send you emails when they are listed in Clovis. There are five homes in Clovis with Isolated / Mother-in law setups, but they are not detached. If you would like a list of either set of homes or help with email alerts, let me know!
