I can easily say, these guys know their craft. They did a great job on my garageI can now say it is part of the house. Everything was done as scheduled.
The ADU we built in the backyard is now my peaceful reading and hobby space. They did impressive work on the structure and interiors. It feels private yet connected to the main house.

Converted our garage into a fully functional ADU suite. Everything from the flooring to the electrical work was done right. The team was reliable and the final result looks fantastic.
The finished ADU conversion was done and completed on time as agreed, I somehow thought it would take forever but they walked the talk.

We renovated our master bathroom and the outcome is stunning. The walk-in shower and fixtures feel modern and luxurious. A1 ADU Contractor workers were respectful and very detail-oriented. We couldn’t be happier with the final result.
They handled our garage ADU project with real professionalism from beginning to end. Questions were answered quickly and progress stayed steady. The crew worked carefully and never rushed important details. The finished unit feels modern and well built. We would absolutely use them again.
Inspection process was extremely detailed and informative. They found the cause of the settling issues around our garage and repaired it before more damage appeared. Very reliable team with great communication throughout the project.
The materials used were high quality, and the craftsmanship was excellent throughout the house. The team listened carefully to our ideas and delivered exactly what we wanted. Highly recommended home builders.
Sylmar homeowners living near landmarks such as the Nethercutt Museum, Sylmar Veterans Memorial Park, and El Cariso Park often look for practical ways to expand living space without relocating. Whether you’re accommodating extended family, creating a private guest suite, or building a rental unit for additional income, a professionally constructed Accessory Dwelling Unit (ADU) offers a flexible and valuable solution. However, without experienced construction planning, projects can face delays, unexpected costs, or structural challenges.
