We provide structural engineering for all ADU types, from garage conversions to new detached units, throughout Sacramento Area.
Units typically under 500 square feet, created by converting a portion of the primary residence. Commonly used for extended family or rental purposes.
Units attached to the primary residence, often constructed as an addition or garage conversion.
Stand-alone structures built on the same lot as the primary residence, offering greater privacy and flexibility.
ADUs created within the basement of the primary residence, maximizing existing usable space.
Units constructed within or above an existing garage. A popular ADU option in Sacramento, La Jolla, and Carlsbad.
Secondary units designed for multi-family residential properties such as duplexes or apartment buildings.
