ADU Builder Los Angeles
The smarter way to build your ADU home.
Building an ADU in Los Angeles doesn't have to be stressful. LADU simplifies your accessory dwelling unit construction with expert guidance, faster timelines, and complete project management from start to finish.
Free, no-obligation site visit
Our team visits your property to assess your space, layout options, and goals — at no cost to you.
End-to-end ADU services
From planning and design to construction and final walkthrough, our team handles every detail so you don't have to.
Transparent pricing
Upfront estimates with clearly explained costs, timelines, and material choices. No billing surprises down the road.
Financing options available
We'll help you explore financing solutions to fit your budget and get your new ADU underway sooner.
What we do
Everything under one roof, from site visit to keys.
Other builders hand you off — to the architect, then the permit expeditor, then the lender, then the contractor. LADU coordinates all four inside a single project plan you can see at any time.

ADU benefits
Why invest in an Accessory Dwelling Unit?
An ADU is one of the smartest long-term investments homeowners can make.
-
Generate passive rental income
Rent your ADU long-term or as a short-term unit to offset your mortgage.
-
Expand space for multigenerational living
A self-contained home for parents, adult kids, or in-laws — close, but private.
-
Boost long-term property value
Adding usable square footage is one of the most reliable ways to grow equity in LA.
-
Create private guest quarters or a home office
A dedicated space that's separate from the main home, however you need to use it.

Future-proof your property
Flexibility for changing lifestyle needs, from kids returning home to aging in place.
