"They built a detached ADU in our backyard in North Park and the whole process was smoother than I expected. The crew was respectful of our space and the finished unit looks amazing — our tenant moved in the week it was done."
"We hired Platinum for a full kitchen remodel and they knocked it out on schedule. No surprise costs, no disappearing for days — just solid work from start to finish."
"Our 1960s bathroom was a disaster and they completely transformed it. They even caught a plumbing issue behind the wall that could have been a much bigger problem down the road."

Call (619) 374-7269ADU costs in San Diego typically range from $150,000 to $350,000 depending on size, finishes, and site conditions. Garage conversions tend to be on the lower end, while detached new builds with full kitchens and bathrooms cost more. We provide detailed estimates after an on-site consultation so you know exactly what to expect.
It depends on the scope. A bathroom remodel might take 3-5 weeks, a kitchen 6-10 weeks, and a whole home remodel several months. Permitting timelines in San Diego can also affect the schedule, which is why we start that process as early as possible.
Most remodeling work that involves structural changes, electrical, plumbing, or adding square footage requires a permit from the City of San Diego. We handle the permit application and inspection process for you so nothing falls through the cracks. Skipping permits can cause serious problems when you try to sell your home later.
California state law has made it much easier to build ADUs, and most single-family lots in San Diego qualify. There are rules around setbacks, height, and size that vary by zone. We evaluate your property during our initial consultation and let you know exactly what's possible.
We offer design-build services, which means we handle both the design and construction under one roof. This keeps the process simpler and avoids miscommunication between separate teams. If you already have plans from an architect, we're happy to work from those too.
We serve homeowners throughout San Diego County including North Park, Hillcrest, Normal Heights, La Mesa, Chula Vista, Encinitas, and beyond. Our office is on University Ave, so we're centrally located and can reach most neighborhoods quickly. Just give us a call and we'll confirm we cover your area.
