Bay Area ADU Contractor

First step of working with Wise Builders is meeting and looking into the construction plans for your home remodel
Step 1: Let's Get Started
Initial Contact

During our first conversation, our team will ask you a handful of general questions regarding your ADU or garage conversion project so that we can better understand your needs and desires. If it feels like we are a good fit for each other, we will assign an experienced project manager to visit your property for your free in-home consultation.


Free In-Home Consultation

The project manager will arrive on the agreed-upon day & time and examine the location of where you plan to build your ADU. Your project manager will be your main point of contact from this point on so that they can truly understand your vision, style, and design ideas for your ADU project.


Scope of Work

If all goes well during the in-home appointment, your project manager will work with you and our office to break down the scope of the project. This phase will include an estimate of pricing for the project, the anticipated process, and the expected timeline for the completion of your new Accessory Dwelling Unit.

Step 2: Build Framework
Meet At Our Showroom

It is incredibly important to us that you’re able to touch and feel the material finishes available to you so that you can make a confident decision on the design of your ADU. Our showroom in San Jose will feature beautifully designed cabinetry, a variety of exquisite tiles, and many more materials to complete your ADU project.


Finalize Gameplan

As you decide on your design and finishes, we will provide you with the final drawings, layout, design, and 3D renderings so that you can truly see how your ADU or garage conversion will look when we complete your project. Your project manager will walk you through all of the possible choices and outcomes you may have before finalizing your project.



At this point, the excitement has built up and we will both be incredibly eager to get started on your dream project! So upon review of all the finalized details, your project manager and our office will work with you to review and sign the contract so that we can finally begin building your ADU unit!

Step 3: Pre-Construction
Obtain Permits

Our team will immediately begin obtaining permits and scheduling appointments with the necessary trade experts to guarantee your home is in the optimal state needed to begin the ADU construction phase. Your project manager will handle this process from A to Z.


Time To Shop!

This is the fun part! Time to shop! You and your project manager will take the time to review all the remaining materials, fixtures, and accessories needed for your ADU Design-Build from our most trusted vendors. These selections will give that final touch to your beautifully designed accessory dwelling unit.



Consistent communication is crucial for a successful process and the peace-of-mind knowing that your project is moving along. Due to our expertise and the care that our project managers have for their projects, you can expect a smooth and transparent process to completion of your new ADU home.


Step 4: Construction Phases

The initial phase of the actual construction will consist of us demolishing the area and removing all of the unwanted materials. Cleaning out the space in a timely manner will ensure that we stay on track with our ADU housing project timeline and prepare us for the framing phase.


Framing and Preparation

Preparation is a key part of a truly smooth installation process, so it is incredibly important that we inspect the space after it’s been demolished and begin the process of framing the structure. As framing is completed, we can then stucco the exterior, interior drywall, plumbing, and other aspects needed to move on to the installation phase.



It’s finally here! The installation process is where your brand new ADU or garage conversion begins to take shape and finally comes to life. Your project manager will ensure that each step is handled with care so that everything is installed in a clean and perfect manner.

Review Final Touch-Ups

Once we complete the installation, your project manager will walk through the entire project with you and review the final punch list to ensure that everything was covered and handled properly. Any adjustments or minor tweaks will be handled in this phase of your accessory dwelling unit project.


Final Inspection

While it is hard to say goodbye, we know how excited you will be to finally enjoy your beautiful new ADU home. So this final walk-through with your project manager will be the final inspection needed to bring your ADU project to completion.


5-Star Review!

If your project manager made your ADU construction process seamless and enjoyable, then let’s give them the praise they deserve! You can find us on all review websites like Yelp and Google, and it truly warms our hearts to hear the good news directly from you!

Owning a home or property is a huge achievement, and it can take years of hard work to finally have a house or land you can call your own. Expanding that space is one of the best investments you can make, so why not commit to a Bay Area ADU renovation project?

A newly constructed accessory dwelling unit (ADU) can be rented out to extended family or friends and provide you with passive income. To bring this vision to reality, you must find and work with the best Bay Area ADU builders.

At Wise Builders, we specialize in not just ADU construction but also garage conversion Bay Area projects. Our gallery of completed ADU projects speaks for itself. Read further about how constructing an ADU can help elevate your property!

What is an Accessory Dwelling Unit (ADU)?

An ADU is an additional living space built within an already-existing residential property. Also known as “in-law apartments,” these smaller, self-contained accommodations are built by converting space in a home or by adding a new structure on the same lot. They may be attached to the existing house or stand alone.

These often serve as homes for extended family members or may be rented out to provide the homeowners with an additional source of income. Some ADUs are used as home offices or to expand the existing home to provide more space for additions to the family. Recent changes to California state law allow property owners to build up to two new ADUs on a single lot.

Challenges Facing ADUs in the Bay Area

Building an ADU on your property in the Bay Area may be complicated by the fact that space is already at a premium. This is compounded by the fact that there are setback requirements that specify how far certain ADUs may be located from the property line. With limited square footage available to you, it’s important to work with a contractor who knows the ins and outs of building under the restrictions.

Fortunately, we bring a considerable amount of expertise that ensures your project won’t hit any snags in the design or permitting process. Our experts will take everything into consideration when planning your new ADU and make sure the plans maximize the amount of available space.

Why ADUs Are a Great Investment

It’s no secret that housing is in short supply throughout the Bay Area. This makes it difficult for those looking for a home to find something that meets their specifications and fits into their budget. Building an ADU on your property gives you the opportunity to transform your home into the space you’ve always wanted it to be.

Whether you want a private space to work, give your extended family members some much-deserved privacy, or offer your new addition for someone else to live in, an ADU can be a sound investment that adds significant value to your home now and in the future.

How To Plan For ADU Construction In The Bay Area?

It is imperative to be fully prepared for an ADU building. Homeowners need to consider their wants and needs toward building a Bay Area ADU. It might be easy to come up with ideas, but you should also ensure you have a bid budget saved up for ADU construction.

  • How Much Does It Cost To Build An ADU?

The costs of building an ADU home vary on the scope of the project, the materials used, and the type of work done, along with any fees a home remodeler might include. Our project managers at Wise Builders are available to meet with you and discuss your ideas and budget to help provide you with a free estimate.

We work diligently to ensure that ADU project costs do not exceed your established budget. Other local accessory dwelling unit contractors may offer their services at a lower price, but you get what you pay for in quality. At Wise Builders, you will receive 100 percent quality work each time.

  • Does Adding An ADU Increase Property Value?
