Install a turnkey modular home in your Los Angeles backyard. We manage site engineering, city permits, crane delivery, and utility hookups directly.
About Our Team
Specialized Prefab ADU and Modular Builders
Our team specializes in turnkey modular construction throughout Los Angeles County. Since 2009, our licensed builders have installed over 200 secondary backyard homes.
A prefab ADU delivers modern living space in half the time of traditional builds. First, our crews inspect crane access and property power lines. Next, we pour an engineered concrete foundation and trench sewer lines. In addition, factory craftsmen construct your modular unit in a climate-controlled facility. Finally, our crane operators set the structure on your foundation in a single day. As a result, you avoid months of noisy backyard construction.

Installation Process
How We Deliver Your Prefab ADU
Our installation team follows four strict engineering stages to ensure rapid delivery and code compliance.
Feasibility & Site Engineering
First, our survey team verifies crane access, overhead utility wires, and lot setbacks. Then, our engineers design the custom foundation plan.
Permits & Factory Build
Next, we submit plans for LADBS approval while factory technicians fabricate your modular unit. Furthermore, state inspectors verify all framing and insulation off-site.
Foundation & Utility Trenching
Meanwhile, our ground crews excavate the site and pour reinforced grade beams. In addition, we trench underground conduits for power, water, and sewer.
Crane Set & Utility Tie-In
Finally, our crane crew hoists your prefab adu onto the foundation. Next, our plumbers and electricians complete final connections for occupancy.
