Team worker made the process painless. The garage door conversion turned out seamless . Thanks a lot good service
I had a stressful lockout situation late at night, but AJ Locksmith is a game-changer. I called their emergency number, and the person I spoke with was calm and courteous. The locksmith, Robert, called when he was on his way and arrived in under 20 minutes. He was extremely professional and friendly, taking one look at the situation and unlocking my door without damaging anything. The best part was that the final cost was exactly as quoted over the phone. No surprise charges or hidden here somsd. I would highly recommend this company to anyone in need of a reliable emergency locksmith.
Professional team delivering solid ADU construction, clear communication, dependable timelines, and quality workmanship.
We hired this ADU builder for a garage conversion, and the entire process was seamless. Highly recommend them for any Accessory Dwelling Unit project!
Im glad that i used their service. They really retrofitted the place and it looks brand new. Very functional. And the price was spot on. Completely worth it. I am glad we contracted them
My garage was just collecting junk, now it’s a fully functional rental unit. The quality of the work is impressive and the attention to detail really paid off. I would definitely hire them again.
I can honestly say these guys know their craft. They transformed my cluttered garage into a beautiful ADU that looks like it was always part of the house. Everything was completed right on schedule.
The project added real value to our home. The garage door conversion gave us the base to create a small apartment for my parents. The team really cared about how it looked, not just how it worked. I’d happily use them again for another project. Thanks again!
I was skeptical at first because I’ve seen some bad garage conversions in the past. These guys proved me wrong with clean lines, solid work, and a perfect finish on the door conversion. The ADU doesn’t just function well, it looks amazing. Friends can’t believe how well it turned out.
The work was done with a lot of attention to detail. The old garage door opening was converted into something solid and stylish. I was surprised at how much this improved the overall look of the home. The new ADU is both practical and great looking.

ADU Construction: Thinking and Design Process
A1 ADU specializes in Accessory Dwelling Unit (ADU) design and building, turning unused garage spaces into functional, stylish living areas. Our process begins with understanding your needs, whether for rental income, guest space, or family use. We then design a custom layout that optimizes your space, prioritizes energy efficiency, and meets all local building regulations. With high-quality materials and expert craftsmanship, we handle everything from permitting to construction, delivering a finished ADU that enhances your home’s value and fits your unique lifestyle.
The ADU Construction Process
Once the ADU design is authorized, our team proceeds with acquiring the necessary permits to ensure full compliance with local regulations. After permits are approved, we begin site preparation, which may include structural assessments and utility connections. Our skilled builders then transform the garage, framing new walls, installing insulation, and adding windows and doors for optimal functionality and comfort. Plumbing, electrical, and HVAC systems are installed to meet modern standards. Finally, finishing touches like drywall, painting, flooring, and cabinetry bring the ADU to life, resulting in a complete, high-quality living space tailored to your needs.
