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 the completion of your new ADU home in Saratoga.

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.

After years of working hard, people become proud homeowners. But did you know that your dream property has the potential to bring in passive income? With a City of Saratoga ADU project, you can have a smaller house on your property that can serve many helpful uses.

Every good project needs a company that brings designs to life. Your project requires the top ADU builder in Saratoga with an extensive set of tools and services that make them a good fit for any home.

Choosing the right contractor for an ADU Saratoga project may seem challenging for many homeowners. Read on further to learn more about why it is important to pick the right choice for building ADUs and learn more about this type of housing too!

What is an ADU Home?

ADU homes are essentially secondary homes located right next to the primary home, and these houses are usually smaller than the primary homes. This unit is also known as a mother-in-law unit or carriage house.

Homeowners have these houses constructed to serve many purposes, and they can be used to provide housing for family, friends, or other people. Many homeowners seek Saratoga ADU construction projects to create small business offices.

Try looking for a company that is not only the most outstanding ADU contractor in Saratoga; but can also help you to develop an ADU construction in the San Francisco Bay Area.

What Does ADU Stand For?

ADU stands for an accessory dwelling unit. An ADU home usually has a kitchen, a living area, and a separate entrance from the primary home.

These homes could be standalone units, attached to a garage, the main home, or even both. Saratoga accessory dwelling units can also be a pleasant and comfortable way to host house guests for a while or even accommodate family members for extended periods.

Is it Legal to Build an ADU on Your Property in Saratoga?

Yes, it is legal if you meet zoning regulations and obtain a Saratoga ADU permit. Your project must comply with all requirements to build an ADU in Saratoga and secure any permits before construction begins.

Depending on the Saratoga zoning district, your property may qualify for one or two ADUs. A legitimate ADU contractor in Saratoga will be familiar with the zoning regulations and share that knowledge with homeowners during a consultation.

The best ADU construction companies always comply with local ADU regulations, Santa Clara county, and California state ordinances. These businesses’ experience with construction rules and regulations has helped them complete projects like remodeling kitchens in Saratoga, CA.

Types of Accessory Dwelling Units You Can Build in Saratoga, CA

There are three main types of Saratoga ADU projects we can develop for you. When you call a contractor, one of their experts will gather the information about your home to determine which kind of ADU works best.

These project managers will gather essential details such as the size of your property and primary home, the location, and measurements, if possible. They will also ask questions such as the main reason why you seek an accessory dwelling unit Saratoga project.

Garage ADU Conversion

Instead of building an ADU from the ground up, contractors can help you perform an ADU garage conversion and transform a pre-existing place of your property into a unit, optimizing the space and saving money in the process.

Many different construction companies have completed plenty of garage conversions in the surrounding areas, and you can view pictures of these projects in galleries available online. Successful garage conversions in Saratoga require a contractor with plenty of experience.

Always seek a team with decades of combined experience in home improvement, design-build, and construction.

ADU Attached to House

Besides Saratoga garage conversions, a primary home can have an ADU built attached to it. An upper floor/attic, an optimized basement, or a side of a house can have an attached ADU constructed.

Attached ADUs have their entrance and share a common entrance with the primary home. An attached Saratoga ADU must also share the same driveway as the main house.

When searching for the right contractor, choose one familiar with building home expansions since they specialize in room additions in Saratoga.

Detached ADU

Detached accessory dwelling units are one of the most common ADUs built. Most homeowners seek a detached ADU Saratoga project because it offers more privacy than other types of ADUs.

Detached ADUs are built and located alongside or behind the main home. Like all ADUs, a detached, smaller house will require at least one parking space. The top contractors will evaluate your property to see which area is most suitable for constructing a City of Saratoga ADU project.

Perks of Building an ADU in Saratoga

ADU construction in Saratoga is already widely known as a reliable way to increase property value. It can add up a good percentage of the property’s initial value and provide additional recurring income if you rent the unit.

Although most contractors are experts in wise construction, plenty of their previous clients have shared how an ADU project has increased the value of their properties.

How Much Does an ADU Add to Property Value in Saratoga?

The exact amount of value that an ADU construction in Saratoga will add directly depends on other factors such as location, overall condition of the space, neighborhood comps, local economy, and more. Aside from monetary value, every successfully built Saratoga, CA ADU project brings joy to plenty of families.

Homeowners should consult an experienced realtor if they want a price determination as accurate as possible. ADU projects aren’t the only house improvement projects that can raise property value.

Finding the Right ADU Builder Near You

The City of Saratoga and surrounding cities like San Jose have plenty of local contractors. Choosing one can be tricky, but finding the best one to build your accessory dwelling units is worth the time. You may find a local ADU building company that offers a low-priced offer but, in the end, won’t be able to deliver top-quality work.

How Much Does an Accessory Dwelling Unit Cost?

Prices can vary widely, depending on factors such as size, type (attached, detached, garage conversion), location, and, naturally, the quality of the building team.

At Wise Builders, you can expect both from our services as a general contractor: a fair budget and excellent quality of work. And if you like our prices and utility, our business partnership can go beyond building accessory dwelling units.

How to Finance Your ADU in Saratoga

Our clients often refinance the mortgage on their primary home or pursue a loan with a federal bank or credit institution to afford the ADU’s payment plan.

You could also pursue the Home Equity Loan and Line of Credit (HELOC), which will allow you to secure the equity percentage of your primary home to obtain funding to build your ADU. You might also have to search neighboring cities for construction services, and you can hire an ADU contractor in San Jose, CA.
