Customer Reviews

Hector Pisano

We hired SouthSTAR Construction to build a 1,200 sq ft ADU in our backyard and honestly couldn't be happier with how it turned out. From the very first meeting, John and his team were straightforward about timelines, costs, and what to expect — no runaround, no surprise charges. They handled everything from permits to final inspection, which took a huge weight off our shoulders. The craftsmanship is excellent; the unit looks like it was always meant to be part of the property. Our neighbors have already asked who built it. If you're serious about adding an ADU and want a contractor who actually knows what they're doing, call SouthSTAR Construction. We've already recommended them to two family members. Five stars without hesitation. Best ADU Contractor!

We used South Star construction to build our ADU from the ground up and had a great experience overall. They were efficient, fairly priced, and very upfront about what was included in their scope of work. Communication was clear, there were no surprise costs, and they delivered what they promised. The project stayed on track, and the quality of work was solid. If you’re looking for an honest contractor who does good work and respects your budget, I’d definitely recommend them.

Felicia Becerra

We came to SouthStar to build an ADU on my grandparents property. At first we considered getting a manufactured home vs. an ADU. John and his team were extremely knowledgeable and not pushy. We ultimately went with SouthStar for the ADU build out and couldn’t be more happy with the results. He was able to work within our budget and still give us a beautiful finished product. You can probably find someone cheaper, but you get what you pay for. Save yourself the headache.

I hired another contractor who left me with a huge mess -unfinished and unpermitted work. John was referred to me and has been absolutely incredible with getting my renovation back on track, he not only gave me advice but helped me get to the point where am finally feeling like there is a light at the end of this nightmare of a renovation. He helped get me connected to quality subcontractors who were honest, fair and completed work on time. I am so thankful to have been referred to John, you won’t regret working with him!

We couldn’t have been happier with the work that was done by SouthSTAR Construction when we had our balcony torn down and rebuilt. John and his team were very professional, showed up on time, paid attention to all the little details needed, always cleaned up at the end of the day, and always communicated throughout the job on what was being done. I’d highly recommend John and his team from SouthSTAR Construction to anyone that needs work done, you won’t be disappointed!

Best ADU ever! Southstar Construction did a wonderful job in building my ADU in Fontana. John the Project Manager was proactive during the whole process; from the plans, design, permits, to construction, and through the final city approvals. His crew were very talented and professional; knew exactly what they were doing. The team gave me feedback when I was unsure. They were very good communicators and were available to answer any questions that I had. It has just the right amount of space for me. Construction was completed timely and the pricing was reasonable for what I wanted. I truly recommend Southstar Construction. I really love love love my new ADU!!! Thank you Southstar Construction!
