PHOENIX — The Arizona Senate passed a measure on Wednesday that will require all larger cities to allow owners of single-family homes to build at least one attached and one free-standing accessory dwelling unit or casita on their lots as a way to help address the state’s huge housing shortage.
The passage of House Bill 2720 on a 17-11 vote came after weeks of negotiations and an amendment that, along with other changes, added that second unit as a right for homeowners.
