These designs are then submitted to the local planning department for approval.

After receiving approval, the construction phase kicks off under the management of experienced ADU builders, ensuring a top-quality outcome. This phase includes securing all necessary permits, site preparation, and construction oversight from the foundation to final touches. Whether you’re planning a tiny home, granny flat, or in-law suite, our team guarantees a smooth process, delivering a stunning and functional ADU that boosts your property’s value and opens doors to rental income opportunities.

What are the ADU Zoning Requirements for Cupertino?

In Cupertino, ADU zoning requirements are designed to allow more homeowners to build accessory dwelling units. All properties zoned for single-family, two-family, or multifamily use may be eligible to build ADUs, making it easier to enhance your property with additional living space.

Eligibility Criteria for ADUs in Cupertino:

1. Single-Family Zoning:

•Properties zoned for single-family use are eligible to add one ADU. This allows homeowners to create additional living space without changing the primary use of their property.

2. Two-Family Zoning:

•Properties zoned for two-family use can also include an ADU. This zoning category is ideal for duplex properties looking to expand their living arrangements or rental opportunities.

3. Multifamily Zoning:

•Multifamily properties zoned for multiple units can incorporate ADUs as well. This provides an excellent opportunity for apartment buildings and other multifamily residences to add more units and maximize their rental income potential.

By meeting these zoning requirements, homeowners in Cupertino can take advantage of the benefits ADUs offer, such as increased property value, rental income, and flexible living arrangements.

In Cupertino, the size requirements for Accessory Dwelling Units (ADUs) depend on the type and configuration of the unit. Familiarity with these regulations is essential to ensure your project aligns with local zoning laws.

ADU Size Categories in Cupertino

  1. Junior ADUs (JADUs):

    • Maximum size: 500 sq. ft.
    • Typically created by converting part of an existing single-family home, JADUs are smaller and more compact.
  2. One-Bedroom Detached ADUs:

    • Maximum size: 850 sq. ft.
    • Fully detached from the main residence, these units provide a cozy living space with one bedroom.
  3. Two-Bedroom Detached ADUs:

    • Maximum size: 1,000 sq. ft.
    • Larger detached units that offer two bedrooms for added space and privacy.
  4. Attached ADUs:

    • Maximum size: Up to 1,000 sq. ft. or 50% of the existing primary dwelling’s floor area, whichever is greater.
    • These units are physically connected to the main residence, providing substantial additional living space.

Adhering to these guidelines ensures that your ADU project complies with Cupertino’s zoning and building standards, helping you create a functional and legally compliant addition to your property.

In Cupertino, the maximum height for detached ADUs is 16 feet. This height restriction ensures that ADUs blend well with the existing neighborhood aesthetics and do not overpower the primary residence.

By adhering to this height requirement, homeowners in Cupertino can ensure their ADU projects comply with local zoning regulations.

The number of ADUs you can build in Cupertino depends on your property’s zoning. Understanding these zoning rules ensures your project adheres to local regulations.

ADU Limits Based on Zoning in Cupertino:

Single-Family Zones:

•One ADU and one Junior ADU (JADU) are permitted per property.

Two-Family or Multi-Family Zones:

•Either two detached ADUs are allowed, or you can convert up to 25% of existing non-living spaces, such as storage rooms or garages, into ADUs.

By adhering to these zoning regulations, homeowners in Cupertino can maximize their property’s potential with additional living spaces.

From January 1, 2020, to January 1, 2025, there is no owner occupancy requirement to obtain an ADU permit in Cupertino. This temporary regulation allows homeowners more flexibility in adding ADUs to their properties without needing to live on-site.

Yes, you can rent out your ADU in Cupertino for long-term rentals. However, the city does not allow ADUs to be rented out for short-term stays, such as Airbnb rentals under 30 days. This regulation helps maintain community stability and ensures ADUs are used for more permanent housing solutions.

In Cupertino, ADUs must adhere to minimum setback requirements. The minimum setbacks are 4 feet from the side and rear lot lines. These setbacks ensure that ADUs are properly spaced from property boundaries, maintaining privacy and compliance with local zoning regulations.

No, dedicated parking is not required for ADUs in Cupertino. This regulation simplifies the process of adding an ADU to your property by eliminating the need for additional parking spaces, making it easier to maximize your available space.

When planning to build an ADU in Cupertino, there are several important factors to consider beyond the basic regulations:

1. Easements:

•Check if your property has any easements that might affect the placement of your ADU. Easements can restrict where you can build on your property, so it’s crucial to identify any existing ones early in the planning process.

2. HOA Regulations:

•If your property is governed by a Homeowners Association (HOA), review the HOA rules and regulations. HOAs may have specific guidelines or restrictions regarding the construction of ADUs, including design, size, and placement.

3. Utility Connections:

•Consider how your ADU will connect to existing utilities, such as water, sewer, electricity, and gas. Ensure that your plans include proper utility hookups and that they comply with local codes and regulations.

4. Lot Coverage and Floor Area Ratio:

•Check the lot coverage and floor area ratio (FAR) requirements in Cupertino. These regulations dictate how much of your property can be covered by structures and the total allowable floor area, respectively.

5. Design and Aesthetics:

•Ensure that your ADU design complements your primary residence and adheres to any architectural guidelines set by Cupertino or your HOA. A well-designed ADU can enhance the overall appeal of your property.

6. Permitting Process:

•Understand the permitting process in Cupertino. This includes submitting plans, obtaining necessary approvals, and scheduling inspections. Familiarize yourself with the timeline and requirements to avoid delays.

7. Environmental Impact:

•Consider the environmental impact of your ADU. Use sustainable building materials and energy-efficient systems to minimize the ecological footprint of your new unit.

8. Fire Safety and Access:

•Ensure that your ADU meets fire safety standards and has adequate access for emergency services. This includes proper installation of smoke detectors, fire extinguishers, and accessible entrances.
