Your Options
Detached ADU
ADU Aces will build a detached ADU on your property up to 1,200 sq. ft. in size. This is a great choice if water, electrical and septic or sewer services are all easily accessed.
Attached ADU
You can expand the footprint of your home by up to 50% with an attached ADU. This is a terrific option for smaller properties, or for owners who want to share a roof with their new tenants.
Garage Conversion
Turn your garage into a “Junior ADU”. We will help you turn your garage into an affordable “studio apartment” with an exterior entryway.
Basement or Second Story Conversion
Space confined? We can help you find more room by turning a basement or seldom-used room into rental space.
