Real feedback from Los Angeles homeowners who trusted us with their ADU projects.
"Love working with GatherADU. I worked directly with Argi and Jesus and would highly recommend anyone needing ADU work to get in touch. We built a 400sq ft detached ADU and are almost done with our project! They are willing to work with you and will discuss options to fit your budget."
"Argi and his team are extremely professional, timely, and reliable. They were always available to answer questions and made the entire process smooth and stress-free. He even handled all the city permitting and land zoning, which saved me a lot of time and hassle."
"I hired Gather ADU to design and build my ADU, and I couldn't be happier with the entire experience. The design process was smooth and collaborative, and the construction phase stayed on schedule. The finished ADU turned out beautiful - both functional and thoughtfully designed."
"GatherADU delivered quality work. Their team looks out for your best interest, provides great customer service and are attentive to detail. I highly recommend them for ADU builds!"
"Their team is incredible. They are very patient and much detailed with all they do. They answered all my tedious questions very clearly. I know now exactly what I need to do for my ADU."
"Just finished up an ADU project and gotta say, I'm super happy with how it turned out, all thanks to Argi and his team. They were awesome to work with - really got what I was looking for, and made all that paperwork and permit stuff a breeze. Seriously, if you're thinking about getting an ADU done, they're the real deal!"
Though backyard homes are typically the most familiar, ADU structures come in various types to fit your property and needs.
A standalone structure separate from the main home, typically located in the backyard. These units offer maximum privacy and flexibility.
Transforms an existing garage into a livable unit. This is often the most cost-effective way to add an ADU without expanding the building footprint.
Built as an extension to the main house, sharing at least one wall. It can be added to the side, rear, or top of the existing home.
Building an Accessory Dwelling Unit (ADU) is one of the smartest investments Los Angeles homeowners can make in 2025. With LA housing costs continuing to rise and rental demand at historic highs, ADUs offer a unique opportunity to generate passive income, house family members, or create a private workspace - all while significantly increasing your property value.
At GatherADU, we specialize exclusively in ADU construction throughout Los Angeles County. Our team of licensed designers, engineers, and contractors has completed over 127 ADU projects across LA - from the Westside to the Valley, from Silver Lake to Long Beach. We understand the unique challenges and opportunities that come with building secondary dwelling units in LA's complex regulatory environment.
LA's housing shortage has made ADUs more valuable than ever. Under California state laws including AB 68, AB 881, SB 9, SB 1211, and AB 2533, the City of LA must approve most ADU applications ministerially, meaning faster approvals with fewer obstacles. Whether you're considering a detached backyard ADU, a garage conversion, an attached addition, or a Junior ADU (JADU), our experts will guide you through every option to find the perfect fit for your property and budget.
The average ADU in Los Angeles generates $2,000 to $3,500 per month in rental income, depending on neighborhood and size. Many of our clients offset their entire mortgage payment with ADU rental income, while others use the space to provide independent living for aging parents or adult children.
Unlike general contractors who occasionally build ADUs, GatherADU is a dedicated ADU company with deep expertise in Los Angeles building codes and regulations. Our comprehensive services include:
