Testimonials
This bathroom remodel has brought new life to our master suite. The luxurious finishes, clever storage solutions, and beautiful freestanding tub create a relaxing sanctuary we didn’t know we needed. They listened carefully to our needs and delivered results that perfectly matched our lifestyle. The project stayed within budget and was completed with minimal disruption to our family. I’m genuinely impressed and would use them again without hesitation for any future projects.
Working from home full-time required more than just a desk in the corner. This crew built a dedicated office with soundproofed walls, custom built-in desks, and floor-to-ceiling bookshelves with a rolling ladder. They also added dimmable sconces and data ports exactly where we needed them. The result is warm, professional, and incredibly functional.
We did a residential remodel on our split level to make it feel less chopped up. They helped us remove a half wall and open up the staircase. The plan and design they came up with was something we never would have thought of ourselves. Now the house feels so much bigger even though we didn't add any square footage. It's just smarter now. I can't believe we lived with the old layout for so long.
They remodeled my kitchen and bathroom beautifully while keeping everything organized and clean. The crew arrived on time every day and worked hard to complete the project on schedule. Their craftsmanship and attention to detail truly stood out. I’m extremely happy with the outcome.
The entire remodeling experience felt well-coordinated and professionally handled. The team worked with a clear plan and kept everything moving without unnecessary delays. The final result really improved the look and feel of the space.
We bought a fixer-upper co-op and needed a complete overhaul, new electrical, plumbing, flooring, and walls moved. We inquired about several quotes in San Jose and D&D Home Remodeling stood out. They managed everything seamlessly from demo to final walkthrough. Communication was excellent and so is our project
D&D Home Remodeling transformed our old and “sad state of affair” bathroom it into a modern curbless shower, double vanity, and heated floors. The crew showed up on time every morning, cleaned up before leaving, and finished a week ahead of schedule. They even helped us choose fixtures that stayed under budget instead of trying to rip us off.
They listened carefully to my ideas and provided helpful suggestions to improve the design. The quality of cabinets, flooring, and finishes is outstanding. I appreciated their transparency in pricing with no hidden costs. Communication was smooth from start to finish. I would definitely hire them again for future projects.
I recently hired D&D Home Remodeling for my kitchen remodel, flooring installation, and sub panel upgrade, and I’m very happy with the entire experience.
From the beginning, Joseph, the project manager, was communicative, professional, and always available to answer questions and keep everything moving smoothly. Dan and the entire D&D team were reliable, respectful, and paid close attention to detail throughout the project.
The quality of the work really shows in the final result. My kitchen came out beautiful, the flooring completely changed the look of the house, and the electrical work was completed professionally and efficiently. The crew kept the job site clean and made the whole process much less stressful than I expected.
It’s hard to find a contractor you can trust, and I truly felt like D&D cared about doing the job the right way. I would definitely recommend Joseph, Dan, and the D&D team to anyone looking for quality remodeling work.
I cannot say enough good things about our experience with D&D Home Remodeling. We just finished a project that turned out absolutely stunning, and while the whole crew was great, our project manager Ilay was the real reason it was such a success.
Ilay was instrumental from start to finish. He was the core driver of the entire project, and honestly, he was essential to getting everything right. It’s rare to find a PM who is that locked into the details while keeping the big picture moving.
A few things that really set them apart:
Quality: The craftsmanship is just on another level. Ilay has a serious eye for detail and made sure the work was executed to the highest standards.
Value: This was a big one for us. The value we got out of this project was honestly beyond our expectations. Seeing the final result, it’s clear that our investment was handled with a lot of respect and integrity.
Service Requested: No matter what part of the service requested we were discussing, Ilay handled it with total expertise. He took the stress out of the coordination and just made it happen.
If you’re looking for a team that delivers high-end results without the typical contractor headaches, ask for Ilay. We’re thrilled with how everything turned out.

The $40,000 grant in California for ADUs refers to the California ADU Grant Program, which provides eligible homeowners with up to $40,000 in pre-development funding to cover costs like architectural plans, permits, and site preparation. This grant is designed to offset upfront expenses for building an Accessory Dwelling Unit on your property. For more detailed information on eligibility and current availability, please refer to our internal article titled Is The California ADU Grant Still Available For Homeowners?.

The cost to build a 1000 sq ft Accessory Dwelling Unit (ADU) in California can vary significantly, but a typical range is between $200,000 and $350,000. This price depends on factors like design complexity, site conditions, and material choices. For a project of this scale, you should budget for permits, foundation work, utility connections, and interior finishes. It is crucial to work with a licensed contractor who understands local zoning laws. For a detailed breakdown of the process and cost-saving strategies, we recommend reviewing our internal article titled Design and Build. D&D Home Remodeling can help you navigate these variables to create a functional and valuable living space.
For homeowners in San Jose, Santa Clara, or Sunnyvale, the cheapest option for an ADU is typically a conversion of existing space, such as a garage, basement, or attic. This approach avoids the high costs of new foundation and framing, significantly reducing your budget. A standard detached new-build ADU can cost over $300,000, but a conversion often saves 30-50% on construction expenses. However, you must verify local zoning and permit requirements, as not all spaces qualify. For a thorough breakdown of costs, types, and regulations, refer to our internal article titled What is an ADU? Accessory Dwelling Units Explained | San Jose, CA. D&D Home Remodeling recommends consulting a professional to assess your property's specific potential for a cost-effective conversion.
Homeowners often underestimate the complexity of an ADU project. The most common mistakes include failing to account for strict local setback requirements and parking regulations, which can halt construction. Another frequent error is underestimating utility connection costs for water, sewer, and power, which can significantly inflate the budget. Poor design choices, like inadequate soundproofing between the main house and the ADU, also lead to future discomfort. To navigate these challenges, you should review our internal article titled 'Avoiding Common Mistakes When Building Your Sunnyvale ADU' at Avoiding Common Mistakes When Building Your Sunnyvale ADU. Proper planning and a clear understanding of local codes are essential for a successful build.
