New ADU Construction in Los Angeles

Detached, ground-up ADUs on your property — designed, permitted, and built.

Overview

What is a new ADU?

A new ADU (Accessory Dwelling Unit) is a fully detached secondary home built on your property — typically 400 to 1,200 square feet. It has its own entrance, kitchen, bathroom, and utilities, and can be rented long-term, used by family, or sold as part of the property.

California law allows most single-family lots in LA to add at least one detached ADU. We handle everything from initial feasibility study through final inspection and certificate of occupancy.
