Custom ADU Construction & Design in Los Angeles
We are a full-service ADU contractor in Los Angeles. We manage the entire process, including architectural design, LADBS plan check approvals, and high-end construction.
About Our Team
Expert ADU Contractor in Los Angeles
We focus exclusively on accessory dwelling units. Since 2009, our team has completed over 200 custom builds and garage conversions as a leading ADU contractor in Los Angeles.
Building a detached ADU is a ground-up construction project requiring grading, foundation work, framing, and independent utility connections. Many general builders handle these projects as secondary work between custom homes. We specialize in them. We self-perform our core trades and coordinate the design, permitting, and construction in-house to deliver a premium guest house or rental property.
