Superior ADUs is an Irvine-based ADU contractor serving Orange County homeowners. The company focuses exclusively on accessory dwelling units — pre-designed models and custom builds, all stick-built on site. They offer a library of pre-designed ADU floor plans in multiple sizes and architectural styles with three finish packages — transitional, modern, or contemporary — giving homeowners a clear starting point before customization. For homeowners who want full flexibility, Superior ADUs also designs and builds fully custom ADUs from the ground up. The company handles design, permitting, and construction coordination end to end. Their pre-designed plan library is already engineered and approved, which shortens the design and permit phase significantly compared to starting from scratch. Featured in the Orange County Register and Redfin. Active project gallery on their site with completed ADU photos. Licensed since 2021, bonded, and carrying $1,000,000 in liability insurance.
