ADU builds near ASU, whole-home renovations, casita additions, outdoor living โ€” Tempe's growing housing market creates real opportunity.

Tempe's Trusted Construction Partner

Tempe's proximity to ASU, light rail access, and dense urban fabric make it one of the best markets for ADU investment in Arizona. We have built casitas, converted garages, and completed whole-home renovations throughout Tempe โ€” from older neighborhoods near downtown to newer builds in south Tempe. We know Tempe's permitting process, setback requirements, and HOA restrictions well.

Tempe City Council adopted its updated ADU ordinance effective December 20, 2024, replacing the more restrictive 2019 rules and opening ADUs to every single-family zoned area citywide. As of July 1, 2026, Tempe is also required to accept submittals under its Preapproved Standard ADU Plan program โ€” a state-mandated pathway (ARS 9-461.19) that lets homeowners select a pre-reviewed design and move straight to an expedited permit, skipping a full custom plan review entirely.

One detail unique to Tempe: the city caps ADU size at 800 square feet, tighter than the 1,000 sq ft state default used in Phoenix and Chandler. Tempe does not charge a dedicated ADU impact fee, though standard building, plumbing, mechanical, and electrical permit fees still apply through Tempe Community Development. If you plan to license your ADU as a short-term rental, note that units built on or after December 20, 2024 trigger an on-site owner-residency requirement for STR use specifically โ€” long-term rentals carry no such restriction.
