Scottsdale's casita ordinance is broadly similar to Phoenix but layered with the city's Sensitive Design overlay in older South Scottsdale and the ESL (Environmentally Sensitive Lands) ordinance covering the North Scottsdale Sonoran Preserve foothills. ESL lots add native-plant inventory, grading review, and a 6-12 week timeline premium. South Scottsdale flat lots are closer to the standard Phoenix path.

Common Scottsdale ADU permit mistakes

Skipping the ESL (Environmentally Sensitive Lands) native-plant inventory on North Scottsdale lots.
Underestimating summer construction curfews (115°F afternoons).
Missing the Sensitive Design overlay review in older South Scottsdale neighborhoods.
Not confirming Scottsdale Water tap size availability — older 5/8" residential taps frequently need upsize for ADUs.
