An Accessory Dwelling Unit (ADU) is an additional living space added onto your primary home, without the need to buy additional property. In San Jose, many residents choose to add on new ADUs for the additional flexibility, increased home value and overall cost-effectiveness versus buying an entirely new home.   

The three main types of ADUs include:

  1. Detached: Often built in a backyard, detached ADUs can be independent living spaces. If you’re hoping to use your ADU as a rental unit, building a detached ADU will give you and your renter privacy.
  2. Interior: If you’re looking to convert your attic, basement or other space already in your home, an interior ADU may be for you. Even though interior ADUs are often smaller, in order to make sure the space can operate as an independent living space, they typically require a lot of remodeling. That being said, they do give you the flexibility to change your space without expanding your property by land.
  3. Attached: These units have a separate entrance but are connected to your main home. Sometimes, they are built above your property and sometimes they are built as an extension. Attached ADUs may require less overall remodeling than interior ADUs and are great for home offices or additional space for your family.


Accessory Dwelling Unit Process

Making sure your new ADU construction runs smoothly requires careful, thoughtful planning. Every aspect of the project needs to be diligently managed with consistent and clear communication.

At Prada Builders, our ADU projects are an 8-step process:

Step 1: Initial Consultation

The journey to your dream ADU starts with a collaborative meeting. We’ll discuss your goals, vision and budget to understand what you’d like to accomplish.

Step 2: Proposal & Scope Planning

Your dedicated project manager will then craft an in-depth proposal that outlines the overall scope of work, cost and timeline. Based on your vision, we will also include preliminary designs

Step 3: Detailed Plans

After a walk through of the space, our architect will create a detailed plan, including 3D renderings. This will give you a strong sense of what your space will look like and allow you to make any changes before demolition begins.

Step 4: Permitting

Our team of experts will submit the layouts to the city and handle the entire permitting process to ensure compliance with all regulations, consistently following up to make sure your plans are approved in a timely manner.

Step 5: ADU Design & Shopping

While the plans are making their way through the city, we will work together on the design, visit showrooms, help you select materials and find fixtures that fit your aesthetic.

Step 6: Construction

As soon as we secure the permits, our expert ADU contractors will begin construction. This step includes constructing your ADU, demoing existing spaces that are no longer needed and installing essential systems.

Step 7: Final Touches & Inspection

This is the fun part! You’ll get to see your vision come to life as we add in your interior finishes, custom features and landscaping. We’ll also go through an in-depth walk through with you to make sure every part of your ADU exceeds your expectations.

How Long Does It Take to Build a New ADU in San Jose?

The length of time it takes to build an ADU in San Jose depends on the size, the scope of the project and the type of ADU. Building an ADU also requires several steps that impact the timeline.

  • Planning: Planning an ADU construction can take a few weeks to 2+ months. This stage includes the initial conversation, walk-throughs, design development and the scope of work proposal.
  • Permitting: The timeline for ADU permitting can fluctuate greatly based on how complex the project is. Our team will create the architectural plans based on your goals, submit it to the city, make any needed revisions and follow up with the city so your ADU renovation project moves along smoothly.
  • Construction: The construction phase is also impacted by how large and complex your ADU build is. This phase is more than just building the ADU itself, it also includes installing plumbing and electrical systems that are needed for new living spaces.

Overall, the amount of time it takes to build an ADU in San Jose truly depends on the project itself and can range dramatically. Your project manager will communicate the estimated project timeline so you’ll have a clear understanding of the build time and can make adjustments accordingly.

What is the Average Cost of an ADU Project in the San Jose Area?

Similar to the average timeline, the average cost of an ADU in the San Jose area varies significantly based on the scope of the ADU project. Factors that impact the cost include the ADU design choices, finishes, materials used, the size of the unit and the type of unit.

Detached ADUs tend to be pricier because they are a completely new structure. The most cost effective ADU to build is typically an interior ADU as it transforms an already existing space. Our home remodeling team will create a scope of work proposal at the start to outline the project pricing. If you have a budget in mind, we will ensure we stick to it so there are no surprise costs.

What Types of ADUs Can I Build in San Jose?

Interior ADUs

Interior ADUs are crafted from an already existing space in your primary home. Common spaces include an attic or a basement. Interior ADUs may offer less privacy than other versions as they are within the main house but they can be cost-effective as they are built within your current space. If you are looking to create an additional living space for family or as a rental without constructing a new structure, an interior ADU is a great choice. 

Detached ADUs

A detached ADU is a standalone structure, separate from your primary residence. If you’re looking for maximum privacy for a rental, office or guest house, a detached ADU is a nice option. That being said, detached ADUs typically cost more to construct and require more space.

Attached ADUs

Attached ADUs are connected to your main house as an extension or above your property. Attached ADUs are great if you are looking for a cost effective ADU option with a good amount of privacy. Constructing an attached ADU may be disruptive as it impacts your primary residence.

If you’re unsure which ADU is right for you, our experts will help guide you to find the best fit option based on your space, vision and goals.

Can a New ADU Increase My Property Value?

Yes, ADUs can increase your property value quite significantly, which is a common motivator for constructing an ADU. Due to San Jose’s competitive housing market, additional structures are a valuable asset. Renting out your AUD can yield a good return on investment and is a good source of additional income.

Renting out an AUD also gives you more privacy than simply renting out a room. If you’re looking to eventually sell your property, the ADU may appeal to many buyers who are looking for increased functionality and additional space for their family, a rental unit or a home office.

How Can I Finance a New ADU in San Jose?

Yes, you can finance your ADU! There are various financing options based on your needs that allow you to manage the building costs effectively. Common financing options include personal loans, which typically have higher interest rates but don’t tap into your home equity. Mortgage refinancing, which gives you better terms and potentially lower your monthly payments.

Home equity lines of credit or loans, allowing you to borrow against your home equity and construction loans given directly by financial institutions are designed to cover the cost of your ADU. Your financial advisor, along with input from our team, can help you find the best way to finance your ADU in San Jose based on your goals.
