Our ADUs Options

Tailored Solutions for Every Need

Custom ADU Designs

We work with you to create a custom ADU that meets your specific needs and complements your existing property. Whether you’re looking for a cozy guest house, a rental unit for additional income, or a private home office, we’ve got you covered.

Garage Conversions

Maximize your existing space by converting your garage into a functional ADU. This cost-effective solution can transform unused space into a beautiful living area, studio, or office.

Detached ADUs

Need more space? A detached ADU offers complete independence and privacy from the main house. Perfect for extended family living, rental income, or a personal retreat.

Attached ADUs

Add an ADU directly to your home with an attached unit. This option seamlessly integrates with your existing structure while providing additional living space.

Junior ADUs (JADUs)

If space is limited, a JADU might be the perfect solution. These smaller units are built within the walls of your existing home, offering a compact and efficient living area.

Increased Property Value

An ADU can significantly boost your property’s value, making it a wise investment for the future.

Flexible Living Options

ADUs offer versatile living solutions for extended family, guests, or as a private workspace.

Additional Income

Generate rental income by leasing your ADU. This extra revenue can help offset your mortgage and improve your financial stability.

Aging in Place

ADUs provide a comfortable and accessible living space for aging family members, allowing them to live independently while staying close to loved ones.

10 Key ADU Building Code Highlights for San Jose, CA:
What You Need to Know

01.

Zoning and Lot Requirements​​
​

• Zoning Compliance: ADUs are permitted in residential zoning districts, including R-1 (Single-Family Residential) and R-2 (Two-Family Residential) zones.

ADU Size Limits
 

• Detached ADUs: The maximum size for a detached ADU is 1,200 square feet.

Setbacks​

 

 

• Front Setback: ADUs must adhere to the same front setback requirements as the primary residence.

• Side and Rear Setbacks: Generally, the minimum setback for side and rear yards is 4 feet.

• Corner Lots: On corner lots, ADUs may have additional setback requirements.

04.

Parking Requirements​

​

• No Additional Parking Required: In most cases, no additional parking is required for an ADU if it is within half a mile of public transit, within an existing structure, or if the lot is in certain zoning districts.

• Detached ADUs: The maximum height for a detached ADU is 16 feet, or 18 feet if the ADU is within half a mile of public transit.

Utilities​

 

 

• Separate Utilities: ADUs may require separate utility connections for water, sewer, and electricity. However, some may be able to share utilities with the main house, depending on the site.

09.

Fire Safety

​

 

• Fire Sprinklers: Fire sprinklers are not required in an ADU if they are not required in the primary residence.
