ADU Real Estate

Perpetual Homes, founded by Katherine Anderson, is addressing California’s housing crisis by offering affordable and sustainable Accessory Dwelling Units (ADUs). With nearly four decades of experience in residential development, Anderson designed ADUs that cater to families’ needs and provide luxurious living at a low cost. Perpetual Homes’ ADUs aim to help families maintain their current configurations, whether it’s through the assistance of “boomerang” youth or “move-down” parents.

Per California law, multifamily investors can have up to two detached ADUs per property, which Perpetual Homes works with. Since Senate Bill 9 became law in 2022, the company’s customers can benefit from fee simple lot splits, which allow homeowners to construct single-family houses and accessory dwelling units on their properties. Perpetual Homes takes pride in being fully transparent about the overall cost and expectations of the project. With an overall total cost of an ADU starting in the mid-$200,000s, Perpetual Homes’ ADUs provide an affordable solution to California’s housing crisis.
