Albuquerque is the Southwest's newest casita-friendly big city: the 2023 Housing Forward ABQ zoning update legalized casitas by-right in R-1 single-family neighborhoods, and the city set a goal of 1,000 new casitas. Rules are straightforward - 750 sq ft cap, 5-ft setbacks, one parking space - and the city offers pre-approved casita designs to speed permitting.
