Transform Your Garage Into A Rentable
Accessory Dwelling Unit or Family
Entertainment Zone!

Treeium Garage Conversions are eco-friendly, innovative, and transform your existing home space into a modern Accessory Dwelling Unit (ADU), perfect for hosting and entertaining family and friends, or as rentable apartment homes for extra income.

At Treeium, our contractors will work with you throughout the scope of your project, from drawings and design, to your floor plan and custom construction.
Because ADU’s are built using existing garage spaces, the process is hassle-free and requires no new construction.

Throughout the process, homeowners in the State of California are given the peace of mind that your project is in the great hands of our professional artisans, and that when all is said and done, you will have a beautiful Accessory Dwelling Unit that will increase the value of your home when it’s time to sell!
The choice between an Accessory Dwelling Unit and Junior Accessory Dwelling Unit really comes down to size.

JADU’s must be no larger than 500 square feet and only include small, plugable kitchen appliances like microwaves, stove tops, and toaster ovens.

An ADU, however, is far more flexible, allowing for a size no less than 850 square feet for a one bedroom and 1,000 square feet for larger than a one bedroom.
