At Lion ADU Builders, we help homeowners create custom attached ADUs that add space, flexibility, and long term value to their property. If you are looking for a smart way to expand your home while keeping the new space connected to the main house, an attached ADU can be an excellent solution.
An attached ADU is a living space that is connected to the primary home while still functioning as a separate and highly useful area. For many homeowners in Oakland, this option creates the right balance between added privacy and convenient access to the main house.
At Lion ADU Builders, we build attached ADUs for homeowners who want more room for family, guests, rental income, or a private work area. If you are still comparing ADU types, you can also visit our ADU Builders in Oakland page or explore all of our ADU Services.
