What is an Accessory Dwelling Unit?

An Accessory Dwelling Unit (ADU) in Los Angeles is a secondary housing unit situated on the same lot as the main residence. These units can be designed in various ways: as an attached addition to the main house, a completely separate structure, or a converted part of an existing space like a garage. Often referred to as “secondary housing units,” “backyard cottages,” or “auxiliary dwelling units,” ADUs provide additional living space within a property.

Benefits of Having an ADU

The rising issue of affordable housing, particularly in Los Angeles, has led to a surge in interest in ADUs as a viable solution. According to a report from the Los Angeles Department of Housing and Community Development, ADUs are increasingly being considered by homeowners and municipalities as a means to address housing shortages.

• Rental Income

One of the significant advantages of adding an ADU to your property is the potential for rental income. This extra income can help offset mortgage payments or other financial responsibilities, making it a savvy financial move for homeowners looking to maximize their property’s earning potential.

• Family Housing

ADUs also offer flexibility for accommodating changing family needs. They can provide housing for elderly parents who need extra care or for adult children returning home. In areas with high housing demand, properties with ADUs can also see an increase in market value, making them a wise investment.

Differences Between ADUs, Guest Houses, and In-Law Suites

While ADUs, guest houses, and in-law suites all serve as additional living spaces, they differ in functionality. An ADU is a fully independent unit with its own kitchen and bathroom, making it suitable for long-term rentals. In contrast, guest houses or in-law suites are typically designed for temporary stays or close family use and may not be as fully equipped as an ADU.

Common Regulations for Building an ADU

Building an ADU requires strict adherence to local zoning laws and building regulations. These rules often dictate size, height, placement, and sometimes the architectural style to ensure the new structure blends seamlessly with the existing neighborhood. Utility provisions such as water, electricity, and sewage must also meet local standards. Consulting with local authorities or professionals familiar with ADU regulations is highly recommended before starting your project.

Types of ADUs

ADUs come in various forms to meet different needs and property conditions:

• JADUs (Junior Accessory Dwelling Units)

Small units within the main residence, often featuring a basic kitchenette.

• Detached ADUs

Independent structures on the property offering ample space and full amenities.

• Attached ADUs

Units that are connected to the main house, balancing privacy with proximity.

• Garage Conversions

Transforming an existing garage into a functional living space, often a cost-effective option.
