Detached backyard units are ideal for creating independent living spaces for guests, family, or tenants. These self-contained homes offer privacy, open layouts, and easy access—all designed to match Union City’s contemporary home styles.
Attached ADUs expand your living area without taking up too much yard space. Perfect for growing families or multi-generational living, these designs provide both convenience and privacy while maintaining architectural balance with your main house.
Transforming your garage into an ADU is a practical and affordable way to add livable square footage. With upgraded insulation, lighting, and finishes, it becomes an ideal spot for a rental unit, guest suite, or creative studio.
For smaller properties, two-story ADUs provide extra room without increasing the footprint. These designs feature versatile layouts that can include a living area below and bedrooms or offices above—combining comfort with modern aesthetics.
A finished basement ADU provides privacy and warmth while making use of underutilized space. With proper waterproofing, stylish lighting, and smart layouts, basements can easily turn into cozy apartments or peaceful guest retreats.
Studio ADUs are perfect for homeowners who value simplicity and efficiency. These open, multi-purpose spaces work great as home offices, short-term rentals, or creative retreats designed to fit seamlessly into Union City’s modern homes.

Why the Bay Area Chooses Gadi Construction
I engaged GADI Constructions Inc to restore my unit in a high rise in San Jose. Right from the beginning Millie, Project Manager, was very professional and when entrusted with the job completed the repair and restoration work smoothly and in time with perfection with time to time progress reporting on phone and through video.
We explored a home addition for our growing family and these folks handled everything with a lot of thought. The builders explained the remodel plan clearly and made the space blend into the house naturally. It was a solid experience all around.
We recently engaged Gadi Construction for a home renovation project, and the experience exceeded our expectations. Their team demonstrated exceptional flexibility, efficiency, and accommodation, adapting seamlessly to our evolving needs while maintaining a high standard of workmanship. The quality of the final output was impressive, reflecting meticulous attention to detail. Millie, our dedicated project manager, along with her team including Mike, fostered a reassuring and collaborative environment throughout the process, ensuring clear communication and minimal disruption. We highly recommend Gadi Construction for any renovation endeavors; their professionalism and commitment to client satisfaction are commendable.

We worked with Nadav from Gadi Construction during the planning phase of our expansion project, and he was a fantastic advisor throughout the process. He helped us think through every detail — from design implications to quality considerations — and brought a thoughtful, thorough, and methodical approach to each discussion.
Nadav was always friendly, highly professional, and incredibly responsive. It consistently felt like he was acting as a truly independent advisor who cared deeply about building long-term relationships and making sure we would get the very best outcome for our project. His proposals were detailed, insightful, and clearly grounded in deep experience.
Although we ultimately moved forward with another contractor who came through a personal referral, that decision wasn’t a reflection on Nadav’s work or professionalism. Based on our experience, we’d be thrilled to work with him in the future and wholeheartedly recommend him to anyone looking for a trusted, high-quality construction partner.
I went with them for a kitchen makeover and it was worth every penny. The design team helped me see options I never thought about.
Their skilled builders were respectful of the house and kept everything tidy. It felt like a real partnership through the whole remodel.
The value added by the new layout is already noticeable. I still walk in and smile because the remodel turned out exactly right.
Taking on a whole house renovation sounded stressful but they took the edge off. They walked us through each stage of the project so we always knew what was happening. The result feels like a true custom home remodeling job.
The bathroom remodel completely changed how our space feels. Their team helped plan everything so the design made sense and looked great. The quality build is obvious in every corner. It’s nice to have a space that’s functional and adds value at the same time.
We worked with this business for a full residential remodel, and it was a great experience. The skilled builders brought the design to life exactly as we imagined. Every room feels intentional and high-quality. I’d happily recommend them to anyone looking for a thoughtful and professional remodel.

The $40,000 grant in California typically refers to the CalHFA ADU Grant Program. This initiative provides forgivable loans of up to $40,000 to qualified homeowners to cover pre-development costs associated with constructing an Accessory Dwelling Unit (ADU) or Junior ADU (JADU) on their property. Eligible costs include impact fees, plan design, soil reports, and permit applications. The loan is forgiven if the homeowner completes the ADU and occupies it as their primary residence for five years, or if the ADU is rented to a low-income tenant for a minimum of five years. This program aims to increase affordable housing stock and help homeowners offset high upfront costs, making ADU construction more financially feasible. It is crucial to check current program guidelines, as funding availability and specific terms can change.
The cost comparison between building an ADU (Accessory Dwelling Unit) on-site versus buying a prefabricated unit depends heavily on project specifics. Generally, prefab ADUs can be cheaper and faster due to controlled factory construction, which reduces labor costs and material waste. However, site-built ADUs offer greater customization and may better integrate with an existing property's architecture, potentially increasing property value. Key cost factors include foundation work, utility connections, permits, and finishes. For either option, obtaining accurate local quotes is essential, as regional material and labor costs vary widely. A prefab might offer more predictable pricing, while a custom build allows for precise budget allocation to different elements.
Rhode Island's new ADU (Accessory Dwelling Unit) law, enacted in 2021, significantly eases restrictions to address the state's housing shortage. The key provision allows for the creation of one ADU by-right on any owner-occupied, single-family lot in zones where single-family homes are permitted, removing the need for a special use permit in most municipalities. The law sets statewide standards, prohibiting municipalities from imposing excessive requirements on lot size, parking, owner-occupancy, or requiring additional utility connections. It aims to increase affordable housing options, support multi-generational living, and make better use of existing housing stock. Local ordinances must now conform to this enabling state legislation, though specific design and placement rules can still be set at the municipal level.
The cost comparison between adding an addition to your main house versus building a detached Accessory Dwelling Unit (ADU) depends heavily on specific project conditions. Generally, a well-planned ADU can be more cost-effective per square foot because it often uses simpler construction methods, avoids major disruptions to the existing home, and may qualify for streamlined permits. However, a basic bump-out addition might be cheaper if it's very small and doesn't require new foundational work or separate utility connections. Key factors include site access, utility hookups, foundation requirements, and local zoning laws. An ADU typically offers greater long-term value through rental income or increased property resale value, which can offset a potentially higher initial investment compared to a simple addition.
