What Our Customers Say
My wife and I hired D&D Home Remodeling for our kitchen remodel, and we’re really happy with how it turned out.
We wanted a kitchen that felt more open and had better storage, and the team helped us figure out a layout that made sense for how we actually use the space.
Mariana, our designer, helped us choose the cabinets, countertops, and finishes without making the whole process feel overwhelming.
There are a lot more decisions involved than we expected! Ilya, our project manager, was easy to talk to and took the time to answer our questions along the way.
The kitchen feels bigger, it’s easier to cook in, and it finally feels like our home.
Glad we went with D&D.
We finished a complete remodeling with D&D home remodeling
We did the kitchen & bathroom and the fire place
We had a great experience with Dan Terrance and the team
We liked to work with the designer Mariana and she helped us with that process and we are static with the results!
We needed a rental ADU built in Sunnyvale to generate extra income before our second child arrived. D&D handled the permits, kept the fixed bid, and finished the construction in four months flat. The unit was rented out within a week of completion. You will not find a more reliable builder in the area.

Dan, Joseph, and Ilay did a great job with our bathroom remodel. They were very responsive through the whole process and helped us with everything from the initial design, materials selection all the way through the final finishing details. Their work quality is excellent and our bathroom turned out just how we dreamed it! We highly recommend them and will be doing more projects with their team in the future.
After discovering water damage under our shower in Santa Clara, we needed an immediate bathroom overhaul. D&D pulled the emergency permits, swapped out the tile and vanity, and got our shower back online in less than two weeks. Total lifesaver when you only have one main bath.

As empty nesters, my husband and I felt ready to upgrade our master bedroom suite, which includes our bedroom, bathroom, and walk-in closet, but after talking to many friends who underwent home remodeling, they described their contractors as people who over promised and under delivered, so we were nervous to commit to this project. After interviewing 5 different contractors, we instantly felt a connection with Dan. His genuine demeanor, work ethic, customer reviews, and construction knowledge caused us to trust him with our vision. He worked with our budget, and he listened to our concerns. But D & D Home Remodeling doesn't end with Dan. As the project manager, Ilay helped with permits, scheduling, and communication. The demolition, tile, and building crews were amazing! Not only were they punctual and cleaned up at the end of their shifts, their workmanship was precise and thoughtful. Shout outs have to go to Terrance, Ricky, and Dante! This crew built my dream master bedroom suite, and it's beautiful! My husband and I felt comfortable asking them questions, and they fixed anything we were concerned about. These guys are top notch, and I was excited with their quick project progress every day. I'm grateful to the designer, Alexandra. Shopping for materials with her was like having an outing with a long-time friend. I will be referring D & D Home Remodeling to everyone who needs construction services in the Bay Area. Thank you D & D Home Remodeling for enhancing our home.
I was very pleased with D & D Home Remodeling. They were very professional and kept me informed in the step by step process. Their prices were competitive with other bids we entertained and they helped us keep within our budget.
Shout out to Dan, Ilay, Mario, Carlos and the rest. Love my new bathroom!

Creating More Space Without Leaving The San Jose Community You Love
San Jose homeowners are finding new ways to make their existing properties work better for changing lifestyles. With housing demand throughout Silicon Valley, many families prefer adding usable space to their current homes instead of searching for a larger property. From the older homes of Willow Glen and Rose Garden to newer communities near Communications Hill and North San Jose, every property has its own opportunities and limitations.
An ADU can provide that flexibility, but successful construction requires more than adding square footage. The new structure needs to fit your property’s layout, respect neighborhood character, and meet local building requirements. D&D Home Remodeling provides Accessory Dwelling Unit services in San Jose with a focus on practical designs, careful planning, and construction solutions that work with your home’s existing features.
Whether your property is near Santana Row, Almaden Valley, Berryessa, Evergreen, or Downtown San Jose, our approach begins with understanding your space before recommending the right ADU solution.
Why San Jose ADU Projects Require Experience With Different Property Types
San Jose has one of the most diverse residential landscapes in the Bay Area. Before construction begins, we evaluate the details that can influence your ADU project:
Older Home Updates
Many San Jose properties were built decades ago and may require electrical, plumbing, or structural improvements before adding new living space.
Limited Lot Space
Urban and established neighborhoods often have smaller lots where every foot matters during ADU planning.
Access Challenges
Side yards, narrow driveways, and limited entry points can affect material delivery and construction organization.
Utility Requirements
Water, sewer, electrical, and heating connections need proper coordination to support the new living area.
Neighborhood Compatibility
ADU designs should complement the existing architecture found throughout San Jose communities.
Permit Preparation
Local approvals, drawings, and inspections must be handled correctly to prevent unnecessary project delays.
Complete ADU Construction Solutions For San Jose Properties
San Jose homes come in many forms, from older single-story residences in Willow Glen to compact properties in established neighborhoods like Cambrian Park and Berryessa. Because every lot has different possibilities, the right ADU approach depends on how you plan to use the space and what works best with your existing home. Our company creates practical ADU spaces through complete Accessory Dwelling Unit services in San Jose handling everything from early planning to the final interior work.
Detached ADUs
A detached ADU gives homeowners the freedom to create a separate living environment without changing the flow of the main residence. These standalone units are commonly used for private family suites, rental housing, guest accommodations, or quiet workspaces where independence matters.
Attached ADUs
For properties where backyard space is limited, an attached ADU can provide additional living space while making better use of the home's existing footprint. This option allows homeowners to add bedrooms, living areas, or private suites while keeping the new space connected to the main property.
Garage Conversion ADUs
Many San Jose neighborhoods have homes with garages that are no longer used for vehicles or storage. Converting this underused area into a livable unit can create valuable square footage without expanding into the yard. We help transform existing garages into functional spaces designed for modern living.
Backyard Guest Houses
A backyard guest house can serve many purposes beyond occasional visits. San Jose homeowners often use these spaces for aging parents, adult children returning home, rental opportunities, or private offices. Each design is planned around comfort, privacy, and everyday functionality.
ADU Design And Permit Planning
A successful ADU starts long before construction begins. Our planning process considers your property layout, intended use, city requirements, and construction needs. We assist with design coordination, documentation, and permit preparation to create a clear path before breaking ground.
Interior Finishing
The final details determine how comfortable and usable your ADU becomes. We complete interior elements including kitchens, bathrooms, flooring, lighting, fixtures, and finishing touches that help transform the structure into a finished living space.
A Clear Process For Building Your San Jose ADU
Adding an ADU involves multiple decisions, approvals, and construction stages. Our process of Accessory Dwelling Unit services in San Jose keeps each phase organized so homeowners know what to expect.
Initial Property Review
We visit your property, discuss your goals, and evaluate available space to determine the most suitable ADU approach.
Planning And Design Development
Our team creates a practical design plan based on your needs while coordinating drawings and required project documentation.
Construction Management
Once plans are approved, we handle the building phase, including structural work, electrical, plumbing, installations, and finishing details.
Final Review And Completion
Before project completion, we inspect the finished space and walk through the details with you to ensure everything is ready.

For homeowners in San Jose, the cost of accessory dwelling unit services varies widely based on size, design complexity, and site conditions. A typical attached ADU might range from $150,000 to $300,000, while detached units often start higher due to separate utility runs. Permit fees, impact fees, and engineering for foundations or utility connections add significant line items to the budget. To maximize your investment, it is wise to plan a cohesive remodel that connects the main house and the new unit. For a detailed breakdown of design strategies and integration tips, you should read our internal article titled San Jose ADU Design And Build: A Guide To Integrating ADUs With Main House Remodels. This resource explains how to align structural systems and floor plans to reduce overall construction costs while increasing property value.
For homeowners in San Jose, using pre-approved ADU plans can significantly expedite the permitting process. The city offers a library of standard plans that have already passed initial plan check, which reduces review time and design costs. However, you must ensure the selected plan fits your specific lot coverage, setbacks, and zoning requirements. While these plans streamline approval, you are still responsible for site-specific modifications and engineering. For financial assistance, we recommend reviewing the internal article titled 'Accessing The California ADU Grant For Your San Jose Project' at Accessing The California ADU Grant For Your San Jose Project to understand available funding. D&D Home Remodeling can help you evaluate if a pre-approved plan is the right fit for your property and guide you through the final permitting steps.
For homeowners in San Jose looking to rent out an Accessory Dwelling Unit, the key is understanding local rental ordinances. The City of San Jose generally allows ADU rentals, but you must comply with specific rules, such as obtaining a valid business license and ensuring the unit meets all building and safety codes. A common requirement is that the property owner must live on-site, either in the main house or the ADU itself. Before listing your unit, verify your specific zoning and any owner-occupancy restrictions. To help fund your project, we recommend reading our internal article titled 'Accessing The California ADU Grant For Your San Jose Project'. You can find this information at Accessing The California ADU Grant For Your San Jose Project. D&D Home Remodeling can guide you through the compliance process to ensure your rental is both legal and profitable.
