Success Stories from Our Satisfied Clients

Working with Tiffany & Steve at ADU-Builds was seamless from start to finish. Their eye for detail, communication, and design expertise transformed our space and removed all the stress from the process. I couldn't be happier.

Carol

Tustin, CA

We hired Steve Pope to remodel our home in Yorba Linda in 2020, and the experience was excellent from start to finish. His pricing was competitive, his subcontractors were reliable and punctual, and the project was completed exactly on schedule. Steve was always willing to accommodate changes along the way, which made the process even smoother. We were so pleased with the work that we hired him again in 2022 to build a beautiful 30x16 gabled patio cover. We would not hesitate to work with him again.

We are absolutely pleased with the results and wouldn’t hesitate to recommend them.

Marietta

Lake Forest, CA

We have worked with Steve Pope and his team on multiple projects in our home, and we couldn’t be happier with the results. From start to finish, the entire crew was exceptional.

Our first project involved expanding the square footage at the back of our home along with a full kitchen remodel. Steve and his team took the time to truly understand our vision and elevated it through thoughtful design and execution. The craftsmanship is outstanding, and the attention to detail is evident in every corner of our new kitchen.

Our second project was an ADU garage conversion, which was completed flawlessly. Both projects were completed on schedule and within budget.

Communication with Steve, the owner, was excellent throughout the entire process. We were consistently informed of timelines and daily schedules, which made the experience smooth and stress-free.

We highly recommend In-Line Construction / ADU-Builds for any renovation or construction needs and look forward to working with them again on future projects.

Working with Tiffany was an absolute dream. Her ability to curate, design, and plan every detail of my home remodel in Orange, CA was nothing short of extraordinary. Her impeccable attention to detail and incredible eye for design brought my vision to life in ways I couldn’t have imagined. Tiffany didn’t just decorate a space, she transformed my ideas into a warm, inviting environment that truly felt like home. Beyond her talent, she was such a joy to collaborate with, professional, creative, and endlessly thoughtful. I’m so grateful for her work and would recommend her to anyone looking to elevate their space or create a new one!

Heidi

Orange, CA

After tenants vacated our rental property, we discovered extensive damage caused by unreported roof leaks affecting ceilings, cabinetry, walls, and flooring. We contacted In-Line Construction for an evaluation, and Steve immediately provided expert insight on the required repairs.

Beyond addressing the damage, Steve offered thoughtful, cost-effective recommendations to improve the home and increase its overall value. His guidance on paint selections, flooring, and interior finishes helped create a cohesive, updated look without unnecessary expense.

We were highly satisfied with the quality of workmanship, professionalism, and efficiency of the In-Line team. We would confidently work with Steve and ADU-Builds / In-Line again and recommend them for renovation, repair, or ADU-related projects.
