California Custom Builders project

Accessory dwelling units

ADUs planned for the property and the people.

Attached and detached ADU construction in Ventura County with feasibility, estimating, design coordination and general contracting.

California Custom Builders

An ADU is a compact project with many of the same systems and approvals as a full residence. Early feasibility and disciplined coordination are essential to protect the budget and use the site well.

California Custom Builders helps owners evaluate access, utilities, existing conditions and the intended use of the new dwelling. We coordinate with the design team as plans are developed and help connect scope decisions to realistic construction costs.

We build attached ADUs, detached ADUs and conversion projects, managing trade sequencing, inspections and finishes through turnover.
