The growing demand for affordable and environmentally sustainable homes in Utah has given rise to many modular building companies. 

Apart from being more affordable and eco-friendly, modular homes are also easier (and faster) to build, generate less waste, and can be extensively customized to meet the needs and tastes of the buyer. 

Utah is served by some of the top modular builders on the west coast, so you’re spoilt for choice when choosing a company to build your home in the state. 

We’ve compiled a well-researched and comprehensive list of the best modular prefab builders in the Beehive State. Let’s get into it!

What We Like

Once you have signed on with Modal, it will take care of the entire ADU construction process, including site surveying, permit acquisition, material shipments, as well as the actual construction. Best of all, the ADU is built and assembled off-site, meaning you won’t have to deal with the day-to-day hassles of ongoing construction in your backyard.
