Unlock Your Property’s Full Potential with an ADU

An ADU (Accessory Dwelling Unit) is a dynamic investment that provides flexible living space and superior financial returns. We specialize in all three primary types of ADU projects. This includes Detached New Builds, which are free-standing units like backyard cottages, offering maximum privacy and top rental value with flexible design. We also expertly handle Garage Conversions, transforming existing garages into living spaces for a faster build time and often a more cost-effective solution than new construction. Finally, we manage Basement Conversions, which involve converting an unfinished basement into a full apartment, utilizing existing square footage while providing excellent insulation and soundproofing.

We handle everything from site planning and structural preparation to utility hookups and internal finishing, ensuring a perfect, profitable final product regardless of the structure type.

Our Full-Service ADU Construction Approach

Building a certified, legal ADU requires specialized expertise beyond standard remodeling. Our process is designed to be fully compliant and stress-free:

Design & Planning: We optimize the unit layout for maximum usability, profit potential, and aesthetic appeal.
Permitting & Compliance: We manage all necessary local permits and zoning requirements in your Utah municipality, guaranteeing your ADU is 100% legal and rentable.
Complete Build-Out: Our work includes all critical components: structural framing, electrical/plumbing, insulation, drywall, finishing, and installing required egress windows and safety features.

We guarantee your new unit is not only beautiful but also a high-performing, long-term asset built to the strictest safety and building standards.

Testimonials

Nuveau Homes did a room addition and a bathroom remodel. They did a great job seeing our vision and putting it together. The work was thorough and well communicated.

Alicia G

This was actually a full remodel with many change orders as we went along. They were very receptive and accommodating to all of our requests. The place turned out beautiful! We are so happy with it! I highly recommend Nuveau Homes.

Jodi V

I cannon recommend Adam and his team enough. We had never renovated a house and Nuveau Homes made the entire process a breeze. They pointed out things I never would have considered updating and provided the perfect amount of guidance to narrow down the millions of choices while still making the space my own. The entire team is kind, respectful and knowledgeable and I'm confident the work was done right from the start.

Alexandria R

Not only did we get a full kitchen remodel, but we got a complete bathroom remodel, vinyl flooring throughout the house, new doors & casings and baseboards - they painted the whole house too! Adam and his crew were fantastic! They were professional and very considerate of the fact that we were both retired and home. I love my house! It's perfect and so thankful to the job they did for us!
