About Geico Builders

ADU Building Services by Geico Builders

Geico Builders offers a range of accessory dwelling unit options designed to suit different property layouts and homeowner needs. Whether the goal is generating rental income, housing extended family, or simply making better use of available space, they provide several ADU types to consider.

Detached ADUs are standalone units built separately from the main house. As a detached ADU builder, Geico Builders constructs these independent structures to serve as rental units, guest houses, or private living spaces for family members.

Attached ADUs are built as extensions of the existing home. These units integrate with the current structure while still providing a self-contained living area with its own entrance and independent amenities.

Junior ADUs (JADUs) are smaller units of up to 500 square feet, created within the existing footprint of a home. A JADU contractor like Geico Builders can repurpose an underused bedroom or interior space, adding a private entrance to create a functional, compact living unit.

Garage Conversions and Home Additions

For homeowners looking to maximize existing structures, Geico Builders also works as a garage conversion contractor. Converting an existing garage into a livable space can be a cost-effective way to add an accessory dwelling unit without the need for new construction from the ground up.

In addition, they handle home additions that can function as ADUs. This approach expands the home's footprint and offers flexibility — whether for accommodating an in-law suite, a granny flat arrangement, or a rentable space.

Geico Builders Reviews

"I think these guys are a class act. I hired them to replace a fence with a wall, matching the stucco wall in the front of the property. I solicited three bids. I selected Geico because Brian really listened and was able to write me a bid that separated out the shared costs with the neighbor from a few extras I wanted on my side of the wall. Brian was very professional and inspired confidence. They also gave a competitive bid! The guys on the crew were super: no-nonsense, get-it-done types, that did very skilled work on the foundation, framing, and stucco. They used quality materials and did not skimp, despite the fixed cost contract. I would hire them again in a second."

"Geico Builders exceeded our expectations with the pergola and landscaping project they completed for us. From the planning stage to the final touches, the entire team was organized, punctual, and very professional. A special thank you to Brian, our Project Manager, for his excellent communication, clear guidance, and attention to detail. He made the whole process stress-free and ensured everything went smoothly. We also want to recognize Oscar, the foreman, whose leadership and expertise were evident in the quality of the work. And a big appreciation to Freevie, the workers team lead, for overseeing the crew with dedication and skill. Their hard work and teamwork truly made a difference. The workmanship is top-notch, and the team kept the site clean and tidy every day. Our backyard now feels like a relaxing retreat.

"It was a pleasure working with Jean and his crew at Geico Builders. After interviewing several firms, we chose Geico because it was readily evident that they had extensive knowledge, experience and professionalism to carry out our project. Jean was an excellent project manager, very knowledgeable and easy to communicate with. He was on top of every aspect of our remodel and guided us through the whole process. Jean gave excellent advice and creative ideas for our project. We wanted to raise our living room floor and other firms pushed for wood framing. Jean explained that concrete would better support the hardwood flooring we planned. To our amazement, his team installed rebar, poured, and leveled the concrete all in one day. The raised concrete floor was nicely done and we were very happy with it. Their concrete pricing was also very fair. Geico also remodeled our downstairs bathroom and removed a wall between the shower and the sink. The results were fantastic! The finish, fit, and flow were exactly what we envisioned. Special thanks to Jeans crew for their excellent workmanship and attention to detail. They were hard working, conscientious, and thorough. They also cleaned up every night after their work. We highly recommend Geico Builders!"
