Efren and his crew built our ADU from scratch and the result is stunning. They handled every single permit, kept us informed the entire way, and delivered ahead of schedule. 10/10 experience.
We had our garage converted into a beautiful studio ADU. Grand Valley Builders made the process incredibly smooth — permits, design, construction. Now we're earning $2,000/month in rent!
Professional team from start to finish. Efren was transparent about costs, timelines, and always answered our calls. The ADU looks incredible and added serious value to our property.
Built a detached ADU in our backyard for my mother-in-law. The quality of the work is exceptional. Grand Valley Builders truly lives up to their motto — they build more than homes.
BBB A+ accredited and they earned it. No surprises, no excuses — just clean, beautiful work delivered exactly as promised. Our addition came in on budget and on time.
