Phoenix changes laws on ADU's/Casitas
After a few years of work new casita/ADU laws and regulations were passed. Looks like they changed the depth of setbacks from your back and side walls (which is big IMO) and listed some specifics about how large the Casita can be depending on your lot and home size. But, it looks like it will be illegal to STR your casita/ADU

I am sure more details will be coming out soon.
