“They have ongoing care and pride in what they do.”

“I found Backyard Unlimited on the web in 2019. I was immediately drawn to them because of their ability to do drawing submittals as well as the construction of an ADU. It was a one stop shop and now that my ADU is complete I can say I am very satisfied with the service, quality and most importantly their ability to honor the price that was in contract. The permitting and plan submittal was the most time consuming part of the process and it did have to do with me requesting a major change in the plans due to new setback rules that would benefit my ADU. Max was supportive and understanding of the changes and once I finally got the permit, it was a matter of scheduling to break ground. Unfortunately it was rainy season and covid which delayed the start. Once it started, things progressed and inspection with city inspectors went well. Because the ADU was in the peninsula in San Mateo County, the scheduling was a little tricky since they drive from the Sacrameto area, but it didn’t bother me that much. What I was most looking for was for the ADU to be built properly, pass inspection, stay within budget and for them to stand behind the quality of the work. I’m happy to say, all those criteria were met. I didn’t go over budget. No major issues with the city inspector were found. I notified them of some quality corrections and they immediately acknowledged and responded which demonstrated to me they have ongoing care and pride in what they do. I would use Backyard Unlimited again in the future and I would definitely recommend them to my friends and family. Good luck on your projects.

“Extremely respectful polite and professional”

“I was looking for a really beautiful tiny house to put on my back deck for an extra bedroom. While backyard unlimited costs more than their competitors, the house has a really unique and cool design (with 7 windows and a slanted roof going up to 11 ft), they were very prompt and friendly, they delivered it 2 to 3 weeks early, and all of the people I spoke with were extremely respectful polite and professional. I cannot recommend them enough.”
