Thinking about adding an ADU to your property? Spindola Construction designs and builds accessory dwelling units across San Jose and the South Bay, from detached backyard units to garage conversions. We handle the whole process: plans, city permits, construction, and final inspection. Licensed and insured, CSLB #870041.
A standalone unit in your backyard, built from the ground up. We take care of design, foundation, framing, plumbing, electrical, and finishes. One crew, one contract, one point of contact.
The fastest path to a rental unit or in-law suite is usually the garage you already have. We convert garages into legal living space with proper insulation, plumbing, and egress, permitted through the city.
Adding on to your existing home? We build attached ADUs and additions that tie into your house cleanly, with structural work, roofing, and finishes all handled by our team.
What it runs comes down to a few things: detached build or garage conversion, the size, the finishes, and what your lot and utilities already have. A garage conversion is the cheaper path since the shell’s already there. A detached unit costs more because it’s built from the ground up with its own foundation, utilities, and roof. We walk your property, figure out what your lot actually needs, and give you a real number before anything starts.
California made ADUs easier to permit than they used to be, but San Jose still has its own process, and every South Bay city is a little different. We handle the plans, the submittal, and the back-and-forth with the city so you’re not stuck at the planning counter. Most ADUs run a few months from permit to finish, depending on size and whether it’s a conversion or ground-up. You get a real schedule up front.
An ADU is one of the few things you can add that pays you back. Rent it for income, put family in it, use it as an office or a spot for aging parents to stay close. It adds real square footage and real value, and in the Bay Area that space is worth a lot. Permitted and done right, it counts when you sell or refinance.
Yes, every ADU does, conversion or detached. We handle the plans and the permit process for you.

These guys make your life easier. I cannot express how thankful I am to have found them during an emergency renovation. They did the job swiftly, with quality construction, and provided updates throughout. Keanu and Greg are very knowledgeable about what needs to be done - and they do it immediately. While others guys were telling us it would take months, Greg arrived at 8am the next morning with a crew and began immediately. We needed a lot done, and other companies wouldn't do it all. Greg said: I start and finish a project. He finished the project quickly, to help us get back in our home as soon as possible. And what's more, he tool diligent photos and videos and stayed in communication with us the whole time. These guys have earned my business for life. Don't hesitate. Call them and make your life easier.

Spindola Construction was extremely helpful, friendly, and on time during all the process of repairing the leak and redoing our bathroom. We really appreciated Greg's expertise in explaining what needed to be done, and how to do it right. Keanu worked with our insurance company to take some stress away from us. Unlike most general contractors we worked with in the past who just charged high prices and just did the minimum to get the job done, Spindola Construction went way beyond.
