Southern California homeowners who trusted us with their ADU — and what happened next.
“We got quotes from four contractors. Payless4ADU came in $40,000 less and actually explained what was in the price. Our 800 sq ft detached ADU was done in 7 months — on time, on budget. We're already renting it for $2,200 a month.”
Maria & Carlos T.
Whittier, CA
“I was skeptical about the 'no hidden costs' claim. But they meant it. The price we agreed on day one was the price we paid. The permit process in Orange County was a nightmare and they handled every single step.”
David K.
Anaheim, CA
“My parents moved into the ADU and I can't put a price on the peace of mind. The team was professional, bilingual, and kept us informed every week. From permit to move-in was under 9 months.”
Sandra R.
Riverside, CA
“We had a complicated lot with setback issues. Their team knew exactly how to navigate the city and got our plans approved on the first submission. That alone saved us months. Highly recommend.”
James & Priya N.
Torrance, CA
“The free site analysis was genuinely useful — not a sales pitch. They told me exactly what I could build, what it would cost, and what the rental income would look like. That transparency is why I hired them.”

Sergio and his team did an amazing job on our project. As a real estate investor, I've worked with a lot of contractors over the years, and communication, quality of work, and attention to detail are extremely important to me. Sergio delivered a true luxury-level finish for a fraction of what I expected to pay. What impressed me most was his attention to detail. He personally walked me through every little detail, every nook and cranny, making sure everything was completed properly. Nothing was overlooked or left undone. If an issue came up, he addressed it and made sure it was right. The finished product exceeded my expectations, and I would absolutely work with Sergio again. I highly recommend him to anyone looking for a reliable contractor who can deliver high-end renovation or ADU work without the typical luxury price tag.
