Arizona State University: Can an existing duplex use Tempe’s single-family ADU rules?
DIRECT ANSWER
Source guidance recorded on 2026-10-15. Confirm the applicable policy year, cohort and property jurisdiction before relying on time-sensitive facts.
The city says properties with an existing duplex, triplex or similar are not eligible under those ADU rules. Additional-unit potential instead depends on the underlying zoning district.
