Scottsdale ADU rules at a glance
Arizona state law preempts local ADU bans — Scottsdale must allow ADUs. Guest houses (a form of ADU) long permitted on large lots. ADU design review required in certain architectural overlay zones. Maximum ADU size is 1,000 sqft under state minimums.
Typical Scottsdale lot profile
Most Scottsdale single-family parcels are about 7,500–15,000 sqft with a median home price near $825,000 in a city of roughly 250K residents. Lot size drives ADU feasibility — smaller lots often still qualify for a JADU even when a detached ADU doesn't fit.
ADU vs JADU
A detached ADU is a new stand-alone structure. An attached ADU is built onto the primary home. A JADU (Junior ADU) is carved out of the existing house with a small kitchenette — usually capped around 500 sqft but easier to permit. Buildability™ checks eligibility for all three types on your specific Scottsdale address.
