Pre-Approved Modular ADUs Across California. 90+ Cities. 400+ Units Installed.
We've delivered prefab ADUs for homeowners, fire rebuilds, and multifamily properties across California. From coastal cities to wildfire zones to apartment complexes. State pre-approved plans compress the permit timeline, so your project moves from signed contract to installed faster than site-built construction can match.
Step 1
Six Designs. Choose Yours.
Six floor plans from 340 to 1,200 sq ft. Studios, one-bedrooms, two-bedrooms, and three-bedrooms. Pick your size, customize the finishes. State pre-approved, so you skip the architect and avoid plan check delays.
Step 2
Fixed Pricing. Zero Surprises.
We survey your site and give you one guaranteed price. It covers foundation, permits, and installation. The price you see is the price you pay. Portfolio pricing available for multi-unit projects.
Step 3
We Handle Permits and Site Prep
Our team manages city permits and builds your foundation while your home is built in our factory. Both happen at the same time, which compresses the timeline by months.
Step 4
Installed as Fast as One Day.
Your finished home arrives on a truck. A crane sets it in place. Most projects go from signed contract to move-in or lease-up in six to eight months.
Vaulted ceilings.
Standing seam metal roof.
Built to last.
Every Abodu has vaulted ceilings, full-height windows, and solid residential framing. Built in our factory, every unit meets strict fire-resistance and energy standards. The finish rivals custom homes. This is permanent housing, not a temporary fix.

"It's a great look. In 10 years, it'll still look good. And in 20 years, it'll still look good. It's pretty classic."
