Purpose-Built Casitas & ADUs for Elevated Living

As a premier luxury ADU and casita builder in Phoenix, Erwin Jaye Homes creates detached and attached living spaces that complement the main home while standing on their own as refined, functional environments.

Our casitas and ADUs are ideal for homeowners who want to expand their property’s livability, versatility, and long-term value — without compromising design cohesion or quality.

Each project is carefully planned to respect the property, architecture, and lifestyle needs of the homeowner.

Designed to Feel Seamless, Not Separate

Luxury casitas and ADUs should feel intentional — not added on.

As an experienced luxury casita builder in the Phoenix metropolitan area, we focus on:

  • Architectural alignment with the primary home
  • Thoughtful site placement and orientation
  • High-end materials and finishes
  • Efficient, livable floor plans
  • Privacy without isolation

The result is a space that feels fully integrated into the property — both visually and functionally.

A Builder’s Approach to Luxury ADUs

What distinguishes Erwin Jaye Homes is our ability to approach casitas and ADUs with the mindset of a custom home builder, not a volume ADU contractor.

The Erwin Jaye standard includes:

  • Design-First Planning — Every decision supports the overall property vision
  • Structural Expertise — Built for longevity and performance
  • Premium Craftsmanship — Elevated execution at every scale
  • Clear, Guided Process — From permitting to final walkthrough
  • Refined Luxury — Timeless design over short-term trends

We build secondary suites that feel primary in quality.

Casita & ADU FAQs

Zoning and building codes vary by city and even by neighborhood. Some areas in Paradise Valley and Arcadia have strict limitations, while Scottsdale tends to be more flexible. We help you navigate local regulations and determine what’s feasible on your specific lot.

Casitas and ADUs can serve as guest houses, in-law suites, home offices, rental units, or private retreats. Depending on the design, they can include full kitchens, bathrooms, and living spaces. We work with you to customize the layout based on your goals.

In most cases, yes — especially in high-demand markets like Scottsdale and Arcadia. A well-designed, permitted ADU adds livable square footage and flexibility that appeals to buyers. It can also provide income potential if rented out long-term or seasonally.

Setback requirements differ depending on the jurisdiction and your lot's zoning. For example, Scottsdale may allow closer setbacks than Paradise Valley. During planning, we work with city officials to ensure full compliance while maximizing usable space.

ADUs can either share utilities with the main home or have separate meters, depending on the design and your goals. We’ll advise on what makes the most sense for your property and coordinate with utility providers during construction.

Timelines vary based on size, permitting, and customization. A typical casita or ADU project takes 4–6 months from permit to completion. We provide a detailed timeline after our initial consultation and keep you updated every step of the way.
