Transform Your Property With A One-Of-A-Kind Accessory Dwelling Unit
At Bridgeview Construction, your trusted custom ADU builder in San Jose, we create fully tailored designs that fit your lot, lifestyle, and goals. Whether you’re adding a rental suite, guest cottage, or multigenerational living space, our design-build team delivers a unique structure that complements your home and adds lasting value.
What Are Accessory Dwelling Units?
As an experienced ADU builder, we create self-contained living spaces built on the same lot as a primary residence. Accessory Dwelling Units can be detached or attached and come in various forms, such as tiny homes, modular homes, or prefabricated structures. Each type offers unique advantages depending on your property’s layout and specific needs.
Why Choose a Custom ADU?
- Designed Around Your Property: Every lot is different. A custom design ensures the ADU fits perfectly. We optimize layout, sunlight, access, and privacy while maximizing available space.
- Built For Your Lifestyle: From open floor plans and vaulted ceilings to built-in storage and smart-home features, a custom ADU adapts to the way you live. Every detail reflects your personal style and daily needs.
- Seamless Integration with Your Home: A well-designed ADU blends beautifully with your main residence. Matching exterior finishes, rooflines, and landscaping creates a cohesive look that enhances curb appeal and property value.
- Higher Return On Investment: Unique design and premium finishes stand out in the rental market. A custom ADU can increase income potential while boosting the long-term resale value of your home.
- A Turnkey Experience: As a licensed general contractor, we manage every stage of the project. From concept and permits to construction and final inspection. We ensure you enjoy a smooth, worry-free experience.
Types of ADUs We Build
As ADU contractors serving San Jose and the surrounding Bay Area, we build all major ADU types to fit your property and goals:
- Detached ADU: A standalone structure built separately from the main home — the most popular option for maximizing privacy and rental income potential.
- Attached ADU: Built as an addition to the existing home, sharing at least one wall. A cost-effective option that makes smart use of your current footprint.
- Garage Conversion ADU: Transform an underused garage into a fully livable space. One of the fastest and most affordable paths to ADU construction.
- Junior ADU (JADU): A smaller unit built within the existing home — typically up to 500 sq ft. Great for multigenerational living without major construction.
- Above-Garage ADU: Built on top of an existing garage, these units maximize vertical space without taking up additional yard area.
Does Your Bay Area Property Qualify?
Before breaking ground, homeowners can use the City’s official ADU Universal Checklist to confirm their property qualifies and understand permit requirements — covering everything from zoning and flood zones to fire access and historic property rules. We handle the process on your behalf, so you don’t have to navigate it alone.
Why Homeowners Choose a Custom Approach
Homeowners who want more than a cookie-cutter plan choose the custom path for creative freedom, design flexibility, and lasting quality. Working with a full-service general contractor means you get a cohesive vision, expert craftsmanship, and one point of accountability from start to finish.
Our Custom ADU Process
- Discovery & Site Evaluation: Every project starts with a detailed site visit and consultation. We assess your property layout, zoning, and utility access, then discuss your goals, budget, and design ideas.
- Design & Planning: Our design team creates a layout tailored to your property and preferences. We develop architectural drawings, recommend finishes, and plan efficient systems to ensure comfort, functionality, and compliance.
- Permitting & Engineering: We handle all the permits, engineering plans, and city approvals on your behalf. Our team stays current with local ADU codes to keep your project on track and on schedule.
- Construction & Build-Out: Once approved, construction begins with quality materials and skilled tradespeople. We maintain clear communication and consistent supervision from foundation to finish.
- Final Walk-Through & Completion: When your ADU is ready, we review every detail together to ensure quality and satisfaction. You’ll receive warranty documentation and ongoing support after completion.
Financing Options For Accessory Dwelling Units
ADU construction can be financed through options like mortgage refinancing, home equity loans, or specialized ADU loans. Exploring these financial tools can help align your project budget with your goals, ensuring a smooth construction process.
Frequently Asked Questions About ADUs
Absolutely. Constructing an ADU involves navigating permits, inspections, zoning compliance, and coordinating various trades. Partnering with an experienced ADU contractor like Bridgeview Construction means having a single point of contact to efficiently manage the entire process from design to final inspection.
An ADU contractor oversees every aspect of the project, including design, permitting, foundation work, framing, electrical and plumbing installations, finishes, and the final walkthrough.

In the competitive Bay Area market, a well-constructed ADU often significantly enhances property value offering benefits like increased rental income potential and higher resale value. It's among the most robust investments for homeowners in this region.
