Preferred Home Builders: The Best ADU Contractors in Los Angeles, CA
What makes Preferred LA’s go-to team for accessory dwelling units.
When it comes to adding an ADU (Accessory Dwelling Unit) to your home, you want to make sure you find the right contractor. There are different options out there — such as a detached ADU or an attached ADU — and it can be tough to know where to start.
Luckily, Preferred Home Builders has a team of experienced ADU contractors in Los Angeles that specialize in designing and constructing top-notch accessory dwelling units. We understand how important it is to find a builder you can trust for such an important investment — that’s why we take the time to get to know each client and their individual needs, and we stay transparent in every aspect of our work, from project estimates to design plans.
With Preferred Home Builders, you can trust that our ADU construction services are of the highest quality. We take pride in our attention to detail and craftsmanship, striving to exceed customer expectations on every project we complete.
What is an ADU?
Accessory Dwelling Units — also known as ADUs, “in-law units,” or “granny flats” — are small living spaces typically attached to (or beside) the main house. They range in size and style from studios to full apartments depending on your needs, and they offer an affordable housing solution for families who need extra space without a major remodel. No matter the size and scope, it won’t be a major project with us.
At Preferred Home Builders, our local contractors specialize in building ADUs with a focus on quality and efficiency. From the beginning of the design process to the completion of construction, you can trust that our team will go above and beyond to meet your needs.
