  Mesa's by-right housing rules for a typical house lot, plus ADU math on sample assumptions, shown as ranges.

  Mesa rules · typical house lot

  High confidence

  Up to 3 homes on a typical house lot

  1 home today · room for 2 more (ADUs count toward the total)

  House + one attached and one detached ADU.

  Typical detached-lot baseline

  3 homes, ADUs included

  Accessory dwellings (ADUs)

  Up to 2 ADUs · attached, detached (backyard) · up to 1,000 sqft · no owner-occupancy rule foundHB2720 permits one attached and one detached ADU. Each may be up to the lesser of 1,000 sq ft or 75% of the main house. Long-term separate rental is allowed; no owner-occupancy condition is assumed.

  Caveats (4)

  • Airport/military and tribal-land exclusions, utility easements and private deed restrictions can prevent development.
  • An extra detached ADU on at least one acre requires at least one restricted-affordable ADU; excluded from this typical-lot count.
  • HB2721 allows duplexes through fourplexes within one mile of the designated central business district and on part of qualifying new subdivisions. It is not a citywide fourplex or transit-radius entitlement.
  • Illustrative entitlement screen, not a parcel determination. Verify zoning/overlays, historic review, recorded covenants, utilities, access, setbacks and building/fire/flood rules before relying on capacity.
