What is an ADU?

An ADU, short for Accessory Dwelling Unit, is a secondary living unit that exists on the same property as a primary residential structure. Also known as “granny flats,” “in-law suites,” or “backyard cottages,” ADUs are self-contained living spaces that typically include a kitchen, bathroom, and separate entrance. They can be attached to the primary residence, located within the existing structure, or built as a separate standalone unit on the property.

The Versatility of ADU Homes

One of the greatest advantages of ADUs is their versatility. They can be adapted to various living situations and serve a multitude of purposes. Let’s explore some common ADU configurations:

  1. Rental Income: ADUs provide homeowners with the opportunity to generate passive income by renting out the secondary unit. This can be an appealing option for individuals looking to offset their mortgage or supplement their monthly earnings.

  2. Multigenerational Living: ADUs are an ideal solution for accommodating aging parents or adult children who desire an independent living space while remaining close to their family. It allows for shared support, privacy, and convenience.

  3. Home Office or Studio: With the rise of remote work and entrepreneurship, ADUs offer a dedicated workspace away from the distractions of the main residence. Whether used as a home office, art studio, or creative workspace, ADUs provide an environment conducive to productivity and focus.

  4. Guest House: Welcoming friends, relatives, or out-of-town guests becomes more comfortable with an ADU. It provides a private retreat for visitors, ensuring both host and guest have their own space and privacy.

  5. Affordable Housing Solution: ADUs can contribute to addressing the growing demand for affordable housing options. By increasing housing density within established neighborhoods, ADUs can help alleviate housing shortages and offer more accessible living options.

The key qualifications for an ADU in California

In California, an Accessory Dwelling Unit (ADU) must meet specific requirements to be considered legal and permitted. The regulations regarding ADUs have evolved over time to promote affordable housing and address the state’s housing shortage. Familiarize yourself with local zoning ordinances, building codes, and any additional guidelines established by your jurisdiction. By understanding these regulations from the outset, you can ensure a smooth and compliant ADU construction process.

Size and Number of Units:
  • Attached ADUs: An attached ADU is an ADU that shares a wall or structure with the primary dwelling. It can be created by converting existing space, such as a garage or basement, or by constructing an addition. Attached ADUs can have a maximum size of 1,200 square feet or 50% of the primary dwelling’s living area, whichever is smaller.
  • Detached ADUs: A detached ADU is a standalone structure separate from the primary dwelling. Detached ADUs can have a maximum size of 1,200 square feet

Property Requirements:
  • Zoning: ADUs are allowed in residential zones, including single-family and multi-family zones, subject to local regulations and zoning requirements.
  • Lot Size: There is no minimum lot size requirement for ADUs; however, the lot should be able to accommodate the ADU and comply with setbacks and other development standards.

  • Off-Street Parking: In most cases, local jurisdictions are prohibited from requiring additional off-street parking for ADUs if they are located within a half-mile of public transit, or if they are created within an existing structure or a converted garage
  • Replacement Parking: If existing parking spaces are converted or demolished to build the ADU, the local jurisdiction may require replacement parking in certain circumstances.

Local Regulations:
  • Local Variations: While the state of California provides general guidelines for ADUs, local jurisdictions have the authority to establish their own specific regulations and requirements. These may include design standards, owner occupancy requirements, and other restrictions. It’s important to consult the local planning or building department for specific ADU regulations in your area.
