About Cupertino

Take advantage of extra square footage and a steady rental income stream by adding a prefab ADU to your property in Cupertino. From studios to two-bedroom models, Abodu's range of custom-made prefab ADUs can elevate any San Francisco Bay Area property.

Instead of being built from scratch on-site, prefab accessory dwelling units are constructed in a controlled production environment for quality-assurance, then delivered and installed in your backyard. This results in a simple, frictionless experience for the homeowner.

What are the benefits of having an ADU?

Whether it’s a compact space for focused work or a more expansive dwelling to host family members and guests, Abodu ADUs are remarkably versatile and functional.

Also called granny flats or in-law units, a prefab ADU in Cupertino provides flexible space for a home office, art studio, or guest house. As housing costs soar, an ADU creates room for aging loved ones, giving them a sense of independence and privacy, in addition to affordable housing options for long-term renters.

Cupertino is a sought-after place to live, and rentals are in high demand, so an ADU would be a great passive income stream. You can rent out your unit to earn several thousand dollars monthly in rental income.

Plus, prefab ADUs can enhance your property value by around 30%. Lastly, ADUs are generally smaller and more energy-efficient than regular houses, promoting a greener, more sustainable way of living.

Building Permits

How do I get an ADU permit in Cupertino?

The process of ADU construction in Cupertino begins with understanding building codes and zoning regulations. The city also offers the option of submitting your architectural and ADU floor plans for a preliminary review before official submission.

Next, you’ll need to prepare a detailed submission package to apply for a building permit, including all relevant plans and documentation. After sending your application to city planning officials and paying the necessary fees, the office will review your ADU design materials for compliance.


What are the top ADU requirements in Cupertino?

Per California state law, ADUs are independent living areas with connections to standard utilities like water, electricity, and sewer services. To determine if your ADU requires a water or electric meter, the city planning office recommends consulting your water provider and PG&E.


How do I finance an ADU in Cupertino?

Homeowners can consider a home equity line of credit (HELOC) or cash-out refinancing to construct their prefab ADU in Cupertino. These financing options can be a great way to fund your additional living space or rental unit without draining your savings.

A HELOC allows you to borrow money based on your equity in your home. It is an open line of credit, similar to a credit card, rather than a lump sum payout.

Cash-out refinancing is a bit different—it's like restarting your mortgage, but for a higher amount. The extra cash above what you currently owe can be used for your ADU project.

FAQs: Prefab ADUs in Cupertino

ADU laws in Cupertino allow homeowners of single-family residences to have two units as long as one is a junior ADU (JADU) and the other is a detached ADU under 801 sq. ft.

For ADUs over 800 sq. ft., you can have either a detached or attached unit of up to 1,000 sq. ft., but not both. In addition, a JADU is no longer allowed if your ADU is more than 800 sq. ft.

On the other hand, multi-family dwellings can have up to two detached ADUs.

The city’s Community Development Department accepts online permit application submissions. For assistance with your ADU plans, you can email the Cupertino planning office or visit in person during business hours to speak to a planner about local and state laws for ADUs.

Santa Clara County’s floor area for detached or attached ADUs must be at least 220 sq. ft. This guideline is the same for JADUs.

There should be four feet of clearance from the front, rear, and side property lines for a detached ADU with a single-family home.
