Los Angeles homeowners are transforming their properties faster than ever through the addition of Accessory Dwelling Units (ADUs). Whether you’re building a detached backyard cottage, converting a garage into a modern apartment, or adding an attached in-law suite, an ADU can dramatically increase both the functionality and long-term value of your property.
Build More Space. Increase Property Value. Create New Income Opportunities.
If you’re considering ADU construction in Los Angeles, you’ve come to the right place.
What Is an ADU?
An Accessory Dwelling Unit, commonly known as an ADU, is a fully functional secondary home built on the same lot as an existing residence. Every ADU typically includes its own:
- Kitchen
- Bathroom
- Living area
- Sleeping area
- Private entrance
- Utility connections
ADUs are often referred to as:
- Granny flats
- Backyard homes
- Guest houses
- Casitas
- Garage conversions
- Mother-in-law suites
- Backyard cottages
Regardless of the name, California has made it easier than ever for homeowners to legally construct ADUs.
Why Los Angeles Homeowners Are Building ADUs
Los Angeles continues to experience one of the highest housing demands in the nation. As property values rise and available land becomes scarce, homeowners are discovering that the most valuable real estate they already own may be their backyard.
Additional Rental Income
An ADU can create long-term passive income through legal rental opportunities.
Multigenerational Living
Keep aging parents, adult children, or extended family close while maintaining privacy and independence.
Home Office
Create a dedicated professional workspace separate from your main home.
Guest Accommodations
Provide comfortable private lodging for visiting family and friends.
Increased Property Value
Well-designed ADUs often increase overall property value while making homes more attractive to future buyers.
Flexible Living Space
ADUs can be used as fitness studios, art studios, music rooms, game rooms, rental units, or future retirement housing.
Types of ADUs
Detached ADUs
A detached ADU is a completely separate structure located elsewhere on your property.
Ideal for:
- Rental income
- Guest homes
- Privacy
- Backyard offices
Attached ADUs
An attached ADU is built onto the primary residence while maintaining independent living facilities.
Ideal for:
- Family members
- Aging parents
- Adult children
Garage Conversion ADUs
Garage conversions are one of the most popular and cost-effective ADU solutions throughout Los Angeles.
Benefits include:
- Existing foundation
- Existing framing
- Faster construction
- Lower costs compared to new detached construction
Above-Garage ADUs
Above-garage ADUs help maximize limited lot sizes by building upward rather than outward.

Where applicable, unfinished basements can be converted into beautiful and functional living spaces.
Junior ADUs
Junior ADUs, also known as JADUs, are smaller living units typically created within the existing footprint of the primary residence.
