About Pros ADU Builders
Pros ADU Builders is a team of local building professionals specializing in Accessory Dwelling Unit (ADU) construction. Founded by Derek M., Marla C., and Jayson R. — a group of experienced contractors who recognized a growing demand for functional and affordable housing solutions — the company was built around a straightforward principle: every inch of a property should work for its owner.
Based in the El Cerrito area, Pros ADU Builders focuses on helping homeowners expand their living space without the stress of relocating or dealing with inflated construction costs. Their team manages every phase of the ADU process, from initial planning and permit navigation through to final finishes and move-in readiness.
ADU Construction Services
Pros ADU Builders handles a range of accessory dwelling unit project types, tailored to fit different property layouts and homeowner goals. Their services include:
- Detached ADU builder services for backyard cottage and standalone unit construction
- Garage conversion contractor work, transforming existing garage space into livable units
- Construction of in-law suites and multigenerational living spaces
- Custom granny flat and Casita builds designed to complement the existing home's style
- Turnkey project management — from permits to paint — so homeowners don't have to coordinate multiple contractors
As a locally licensed ADU contractor, Pros ADU Builders ensures all projects are built to comply with local city codes and are designed to pass inspection. They do not use cookie-cutter designs; instead, each build is customized to the specific property and the homeowner's needs.
An Accessory Dwelling Unit is a secondary housing unit located on the same property as a primary residence. It can serve a variety of purposes, including generating rental income, accommodating extended family members, or providing a dedicated workspace. The timeline and complexity of any ADU project will vary depending on the scope of work involved.
