Yelp Logo

I had a great experience with DevArt8 Construction! Everyone involved with the project did a great job. What stood out to me was their well-managed remodel process, especially handling permits and helping us through material selection.

Reviews in Houzz

I was initially really nervous about building an ADU and worrying about whether it would be all to code. But Ray, Matthew and Eve made the process simple and straightforward, and you can tell they know the local zoning requirements and building codes inside and out.

Reviews in Houzz

Top notch remodeling company serving Milpitas. Owner Ray is communicative, friendly, helpful. Give them a call for home construction; you won’t be sorry.

I’m incredibly grateful for Ray and Devart8 team. Just can’t believe that he succeeded to solve all the mess that other contractors left us with and pass finals on all.
