OakADU: A Full-Service ADU Contractor in California
OakADU offers a turnkey approach to accessory dwelling unit (ADU) projects, covering financing, design, construction, and property management. Operating throughout Los Angeles County and the broader Southern California region, they aim to guide homeowners through every stage of the ADU process — from initial concept to completed build.
An accessory dwelling unit — also referred to as a granny flat, in-law suite, backyard cottage, or secondary dwelling unit — is an additional living space located on the same property as a single-family or multi-family home. OakADU works with four main types of ADUs:
- Detached ADU: A standalone structure built from scratch, typically situated in the backyard. As a detached ADU builder, OakADU handles the more involved permitting and construction process that this type of project requires. It offers strong privacy but tends to be the most time-consuming and costly option.
- Garage Conversion: As a garage conversion contractor, OakADU renovates and often expands existing garages into functional living spaces. This is generally a more affordable option and is commonly used as a rental unit or home studio.
- Attached ADU: Built as an extension of the main house — to the side, above a garage, or as a second story — this option is typically the most cost-efficient way to add square footage to a property.
- Interior Conversion: Sometimes called a basement apartment or mother-in-law unit, this involves converting an existing interior space such as an attic or basement into a dwelling unit. Permits for this type tend to be more straightforward to obtain.
What OakADU Offers Beyond Construction
OakADU positions itself as more than just an ADU builder. In addition to designing, drafting, and constructing the unit, they also assist homeowners in getting pre-qualified for a cash-out refinance to help fund the project. Once the ADU is complete, they can also help find renters or manage an Airbnb listing on the homeowner's behalf.
Their goal is to help homeowners develop a strategy that maximizes the value of their property — whether that means generating rental income or simply adding usable living space. They work with architects across California to provide design services at a reasonable cost, and they place particular emphasis on keeping the permitting process on track to avoid costly delays.
OakADU is operated by Oakmont Builders, Inc., a family-owned general building contracting company. Oakmont Builders focuses on managing the construction development process from concept through to completion, with an on-site management team dedicated to client communication and project oversight.
Serving Homeowners Across California
OakADU's services are available to homeowners throughout Los Angeles County, Southern California, and the wider state. Their process is designed to reduce the complexity and stress that often comes with major construction projects like building a casita, granny flat, or in-law suite.
By handling permitting, design coordination, construction management, and even post-build rental support, OakADU aims to offer a comprehensive path for homeowners looking to add an ADU to their property without navigating the process alone.
