What Is an ADU?

An Accessory Dwelling Unit (ADU) is a secondary housing unit that is built on a property that already has a single-family or multi-family home. ADUs can take various forms, including detached structures, attached additions, or conversions of existing spaces like garages. They typically feature a full kitchen, bathroom, and separate entrance, providing independent living quarters on the same property.

Types of ADUs

Detached ADU

Stand-alone structures built separately from the main house, offering complete autonomy and privacy.

Attached ADU

Extensions or additions to the primary residence, seamlessly integrated into the existing structure.

Garage Conversion

Repurposing existing space within the property, such as garages or outbuildings, into livable units.

Interior Conversion

Transforming an existing basement or attic space within your primary residence.

Why Build an ADU in Los Angeles?

An ADU isn't just a structure, it's an investment in your future
With the flexibility to rent it out for passive income or use it as a multi-generational living solution, you’re not just adding square footage but value to your life and your property!
Rental Income

Generate additional monthly revenue by renting out the ADU to tenants, providing a reliable source of passive income.

Increased Property Value

ADUs enhance the value of your property, contributing to long-term equity growth and resale value.

Flexible Living Space

ADUs offer versatile options, from accommodating family members to creating home offices, guest quarters, or hobby spaces.

Sell the ADU Separately

City law changes now permit the sale of detached ADUs separately. Eligible parcels can subdivide, offering the potential to pay off mortgages or generate extra cash.

Understanding New ADU Regulations in Los Angeles

A Simplified Overview
At GO ADU, we’re well-versed in your city’s specific rules and ordinances, ensuring a smooth journey.
Lot Size and Setbacks

California no longer imposes minimum lot size requirements and has reduced setback requirements. Each city has its own specific setback requirements.

ADU Size

In Los Angeles County, ADUs can range from a minimum of 150 square feet to a maximum of 1,200 square feet. Attached ADUs are limited to half the size of the main residence, while detached ADUs can reach the full 1,200-square-foot limit.

ADU Limit

The number of ADUs you can build on a lot depends on the type of ADU you want to build and the zoning of your specific property. A feasibility study is a great tool to learn about the potential of your lot.

Application Review

State law has reduced the time that municipal buildings have to act on an ADU application from 120 days to 60 days.


Most requirements for additional parking to accompany an ADU have been waived, especially if the property is located within at least ½ mile of public transportation.
