ADU Construction Services in Los Angeles County

An Accessory Dwelling Unit (ADU) is a secondary housing structure built on the same lot as your primary home — and in today’s California market, they’re one of the smartest investments a homeowner can make. Whether you call it a granny flat, a casita, or a backyard cottage, an ADU dramatically increases your property value while giving you flexible living space.

At Gators General Construction, we’ve built ADUs across the San Gabriel Valley for homeowners who want to house aging parents nearby, generate rental income, create a dedicated home office, or simply add livable square footage without the cost of moving. We handle everything from permits and engineering to framing, electrical, plumbing, and final inspections.

California’s ADU laws have become increasingly favorable — in many cases, you can build an ADU up to 1,200 sq ft with streamlined permitting. Our team stays current on local ordinances across Los Angeles County so your project moves forward without costly surprises.
