Phoenix's updated building construction code aligns with the city's broader commitment to sustainable growth in a desert environment. For backyard casitas and detached guest houses, this means new expectations around plumbing fixtures, water efficiency, and how interior square footage is planned and utilized. Key among these updates is alignment with EPA WaterSense standards for plumbing fixtures.

AzADU casitas aren't modular boxes dropped in a backyard. They're stick-framed on a permanent slab-on-grade concrete foundation, built to the same structural standard as a primary residence. Dimensional architectural shingles with UV-resistant properties cap the roof, while gutters manage Arizona's intense monsoon runoff. Every unit is a real investment and it's protected like one.

AzADU was built on the philosophy that every casita we construct should feel like a natural, high-end extension of your home. That means our standard package includes finishes that many luxury builders charge extra for. Here's a closer look at what's included in every AzADU build — and why it matters.
