Two new laws require cities to permit ‘missing middle housing’ near city centers and ADUs on all single-family lots.

Two new Arizona laws will permit denser development near city centers, overriding local zoning codes, according to an article in The Real Deal.
“House Bill 2721, dubbed the ‘middle housing bill,’ requires cities with more than 75,000 residents to change zoning and other regulations to allow for duplexes, triplexes, fourplexes and townhomes within a mile of their central business districts.” The article notes that “The middle housing bill didn’t go as far as earlier legislation that would have stripped zoning controls from cities and prevented them from imposing HOA requirements on new communities.”
The second bill, House Bill 2720, requires cities of the same size to permit accessory dwelling units (ADUs), sometimes known locally as casitas, on single-family lots with no design or parking requirements.
