ADU Construction in Walnut Creek & the East Bay

Explore the potential of additional living space on your property. Rojas Construction & Remodeling works with homeowners on ADU construction and conversions, coordinating the construction scope with approved plans.

Start with the property and your goals

Tell us whether you are considering a detached unit, an attached space, or a conversion. Feasibility depends on the property, utilities, existing structure, and local requirements. The first conversation helps identify the next steps.

Coordinate the construction details

An ADU brings together structural work, framing, plumbing, electrical, insulation, kitchens, bathrooms, and finishes. A clearly defined scope helps homeowners understand responsibilities, selections, and scheduling.

Prepare for your consultation

Share your project city, intended use, any drawings you already have, and your preferred timing. Design, engineering, permit responsibilities, and fees should be clarified in the written project scope.

ADU planning questions

Can an existing space become an ADU?

Conversion feasibility depends on the existing structure, access, utilities, and local requirements. Share your drawings and property details so the construction scope can be evaluated.

Are design and permit fees included?

These responsibilities and fees must be identified in the written proposal. Construction pricing should not be assumed to include architectural drawings, engineering, or permit fees unless expressly listed.

What should I bring to the first conversation?

Your project city, intended use, photographs, existing plans, and goals help us discuss practical next steps.
