Luxury ADUs & Detached Guest Houses
Beyond the Backyard Cottage
In 2026, the Accessory Dwelling Unit (ADU) has evolved into a centerpiece of the luxury estate. Whether you require a private residence for aging parents, a sophisticated guest sanctuary, or a detached executive office, Simon Joseph Custom Homes builds “Casitas” that offer full independence without compromising your primary home’s architectural integrity.
2026 Luxury ADU Features
We build independent homes, not “glorified sheds.” Our ADU projects include:
Independent HVAC, high-efficiency plumbing, and separate electrical metering where required.
Integrated infrared saunas, steam showers, and floor-to-ceiling glass walls to maximize natural light.
Hand-troweled Venetian plaster, rift-sawn white oak flooring, and custom-integrated millwork that hides technology.
Retractable glass walls that open onto private courtyards or pool-side lounges.
Navigating the Permit Gauntlet
Building an ADU in North Dallas is often a bureaucratic challenge. Each municipality has distinct, rigorous standards for detached living spaces:
We manage the complex Board of Adjustment hearings and Neighborhood Overlay requirements.
We ensure compliance with the "Backyard Cottage" (BYC) standards, including the 10-foot separation and 400–1,100 sq. ft. footprint limits.
We specialize in architectural matching, ensuring your guest house uses the same 100% masonry and roof profile as your main residence.
We handle the specific utility and short-term rental licensing requirements for secondary units.
The 3D Visualization Advantage
Before we break ground, our 3D Visualization Software allows you to walk through your ADU virtually. You can test different floor plans, see how the unit sits on your lot relative to your pool or primary home, and finalize material selections with 100% certainty.
