How much does a casita or ADU cost in Phoenix?
Answered by AskBaily Editorial · Updated
Short answer
Conversion of an existing attached space (garage, bonus room) into a legal JADU: $60K-$135K. Detached stick-built casita 500-750 sqft with kitchenette + bath: $180K-$310K. High-end detached casita 900-1,100 sqft with full kitchen + bath + laundry: $345K-$525K. HB 2720 removed many municipal blockers but city permits, HOA review, and utility tie-ins still gate timeline.
