ADU Design-Build • Santa Barbara & Ventura County • CSLB #1146801 • BBB A+ Rated
Hive ADU is a design-build ADU contractor serving Santa Barbara and Ventura County. Every project starts with a feasibility review: we confirm zoning, setbacks, lot coverage, utilities, access, and your permitting path before any design decisions are made. That front-loaded work is what keeps a project from stalling at the counter or coming back with expensive redesigns.
From there, design, engineering, permitting, and construction all run under one in-house team. One group owns the project from first drawing to final inspection. Whether it is a custom detached ADU or a compact backyard build, your ADU is built on your lot, on its own foundation, tailored to the property and how you plan to use it over time.
As a local ADU construction company, we are licensed and insured under CSLB #1146801 and hold an A+ rating from the Better Business Bureau. For a full walkthrough of feasibility, permitting, and construction in the county, see our Santa Barbara ADU Guide.
