A thoughtfully designed ADU or casita can do so much more than add square footage to your property. It can provide a private guest retreat, a comfortable home for family, a dedicated space for work or hobbies, or even a completely independent living space.

At Arlington Custom Builders, we design and build custom ADUs and casitas that feel like a natural extension of your home while offering the privacy and functionality of a separate space. From full kitchens and comfortable bedrooms to spa-inspired bathrooms, offices, laundry rooms, exercise spaces, and garages, we can create a space tailored to the way you plan to use it.

With decades of experience building and remodeling homes throughout Arizona, our team handles every detail with the same attention to craftsmanship and design that goes into every Arlington project. Whether you're envisioning a cozy guest casita or a fully equipped secondary residence, we'll help bring your vision to life with thoughtful design, quality materials, and expert construction.
