"The team handled every permit detail and finished two weeks ahead of schedule. My mother has her own space, and we have our privacy back. The price was locked from day one — no surprise change orders, no hidden fees."
Unfiltered reviews from homeowners and investors across California who built ADUs with us. Every testimonial is from a completed project — no placeholder quotes, no anonymous reviews.
"We interviewed four contractors before choosing ADU Construction. They were the only team that explained the zoning constraints clearly, gave us a realistic timeline, and put the price in writing before asking for anything. My mother moved into her 720 sq ft backyard home in April. She has her own kitchen, bathroom, and entrance — real independence — but she is thirty steps from our back door. Two weeks ahead of schedule, price never moved."
Filter reviews by the type of ADU the client built. Every one is from a completed, permitted, and inspected project.
"The team handled every permit detail and finished two weeks ahead of schedule. My mother has her own space, and we have our privacy back. The price was locked from day one — no surprise change orders, no hidden fees."
"Our garage became a rental that covers half our mortgage. The pricing was transparent from day one — no surprise change orders, no delays, no excuses. It rented three weeks after final inspection."
"We interviewed four contractors. ADU Construction was the only one that explained the zoning constraints clearly and gave us a realistic timeline. My father has his own entrance and kitchen, and a connecting door when we want it."
"Our lot is forty feet wide and sloped at the back. Every contractor we spoke with said a detached ADU was impossible. ADU Construction proposed building above our garage instead. It rents for $3,200 a month now."
"We had a finished basement we barely used. They carved out a 440 sq ft junior ADU in about three months. The permit came through in five weeks. We rent it for $1,900 a month now."
"We owned a 1960s office building with two floors of dead space nobody wanted to lease. ADU Construction ran the feasibility study and built out six residential units over eleven months. Net operating income has more than doubled."
"We built a 480 sq ft detached studio for short-term rental. High ceilings, ocean-facing glazing, and a full outdoor kitchen maximize the small footprint. It pays for itself in rental income and added property value."
"They converted our two-car garage into a studio with a kitchenette and murphy bed. Rented within three weeks of final inspection. The team was honest about timeline from day one and delivered exactly what they promised."
"Our adult son moved back home after college. The attached ADU gave him his own entrance from the back yard and his own bathroom and kitchen. Everything we hoped for. Took one week longer than scheduled, but the quality was worth it."
"The structural work was the part that worried me most. Their engineer walked me through every calculation. The moment frames preserved our open parking bays. It is a real one-bedroom unit — not a converted attic."
"Wide doorways, a walk-in shower, and an attached screened porch were designed specifically for my aging parents. The team understood what mattered. It never felt like a construction project — it felt like they were building for their own family."
"We converted an oversized guest wing into a legal junior ADU. The permit came through faster than any project I have been involved with. The unit is compact but feels spacious — the design made every square foot count."
Post-completion survey results from the last twelve months. Every client receives the same four-question survey at final walkthrough.
Craftsmanship, materials, and finish detail
Pricing clarity and communication
Adherence to published schedule
Speed and clarity of the permit process
The number they signed is the number they paid. No surprise change orders, no retroactive billing, no line items added after the fact.
The person who did the feasibility walk is the person who handed over the keys. No department transfers, no re-explaining the project.
Every Friday: progress summary, photos, completed milestones, and the plan for the coming week. Silence is not an option.
Delivered in writing at handover. We stand behind the structure we built for a decade, and the finishes for one year.
We will connect you with two or three past clients in your area who built a similar ADU type. Ask them anything — the good, the bad, and the frustrating parts of the process. We do not coach them.
