AZ HB2110

Municipalities with populations of 150,000 or more must establish objective standards within ninety days to allow multifamily residential development or adaptive reuse on at least ten percent of existing commercial, office, or mixed-use parcels without requiring rezoning, conditional use permits, or public hearings.

Municipalities may exclude up to ten percent of commercial parcels as essential commercial or employment hubs and may re-analyze eligible parcels every ten years.

Objective standards for multifamily development are limited to site plan review, adequate utilities, building and fire code compliance, documentation of economic or functional obsolescence, parcel size requirements (1-20 acres), and a ten-percent set-aside of units for moderate or low-income housing for at least twenty years.

Demolition permits cannot be withheld for qualifying projects; height limits are capped at five stories except two stories within 100 feet of single-family zones, with setbacks and density equivalent to the highest multifamily zoning district within one mile.

Exemptions apply to historic districts, lands near military or commercial airports, and municipalities located on tribal land; the law applies retroactively from December 31, 2024.
