Custom ADU Development Done Right
From design to permits to build, Builders Group and Design delivers accessory dwelling units homeowners trust.
What Is an ADU?
A Smart Way to Expand Your Property's Potential
An accessory dwelling unit, or ADU, is a fully independent secondary residence built on the same lot as your primary home — whether it's a detached backyard cottage, a garage conversion, or an attached suite. More homeowners are choosing to build an ADU because it delivers real, lasting value: additional income, flexible living arrangements, and a stronger property.
As a full-service general contractor, Builders Group and Design manages every stage of custom ADU development in-house — from initial design and engineering through permitting, construction, and final inspection. Homeowners work with a single, accountable team from start to finish, backed by our reputation for dependable craftsmanship and clear communication.
Rental Income Potential
A well-built ADU can generate steady rental income, helping homeowners offset their mortgage or build long-term wealth.
Multigenerational Living
Give aging parents or adult children a private, independent space while keeping family close.
Flexible Living Space
Use it as a home office, guest suite, or private studio — an ADU adapts as your household's needs change.
Increased Property Value
Adding livable square footage is one of the most reliable ways to grow the long-term value of your property.
