Sacramento’s Premier Garage Conversion & ADU Builders

Your garage is the most underutilized real estate on your property. Whether you are looking to build a private in-law suite, a dedicated home office, or a high-yield rental property, converting your existing garage is the fastest and most cost-effective way to add an Accessory Dwelling Unit (ADU) to your home. At GBG Construction Inc. (License #1071343), we specialize exclusively in high-end garage conversions across the Greater Sacramento area. From architectural planning and navigating county permits to Title 24 energy compliance and flawless interior finishes, we handle the entire build.

Building a ground-up, detached ADU is a massive undertaking that requires heavy excavation, new foundations, and long timelines. Converting your existing garage bypasses the heaviest construction phases and takes advantage of California's streamlined ADU laws. Here is why Sacramento-area homeowners are choosing garage conversions: No Replacement Parking Required: Under current California state law, if you convert your garage into an ADU, you are generally not required to build new off-street parking to replace the lost spaces. Keep Your Yard: A conversion maximizes your property’s interior footprint without sacrificing your backyard or outdoor living space. Streamlined Setbacks: Because the structure already exists, you bypass the standard 4-foot side and rear setback requirements that apply to newly built, detached ADUs. Faster Permitting & Build Times: With the foundation, framing, and roof already in place, conversions can typically be permitted and built in a fraction of the time of a detached unit.

A converted garage shouldn't feel like an afterthought—it should feel like a premium, custom-built studio or one-bedroom apartment. We don’t cut corners with basic builder-grade materials. Our standard ADU finishes are designed to command top-tier rental rates and maximize property value: Modern Lighting: Architectural matte black track lighting and dimmable LED flush-mount fixtures to make the space feel bright, modern, and expansive. Premium Bathrooms: Frameless glass shower enclosures, high-end tile work, and sleek, modern vanities. Custom Kitchenettes: Flawless cabinetry, durable quartz countertops, and perfectly integrated appliances. Superior Climate Control: Level-5 drywall finishes using professional skimming blades, Title 24-compliant insulation, and highly efficient split-system HVAC for independent climate control.

Because local zoning laws and permit requirements vary from city to city, you need a contractor who knows the local landscape.
