What is an ADU?
There are four kinds of ADUs:
Detached ADU
This type of ADU has to be constructed from scratch and is sometimes referred to as a backyard cottage because it is usually situated in the backyard, separate from the main house. It’s basically a little house in your yard.
One of the benefits of a detached ADU is privacy. However, a more complicated permitting and construction process will make it a more time-consuming and expensive project, especially without an experienced builder on your side.
Garage Conversion
A garage conversion, as the name implies, is an ADU that is built by renovating and often expanding an existing garage. It is a little lighter on the wallet and still comes with privacy and a lot of convenience.
Often these are used as home studios or rental units that can still provide the homeowner with significant extra income for a lower initial investment.
Attached ADU
An attached ADU is built as an attachment, often to the side of the main house, on top of a garage or even as a second story.
It does come with a little less privacy than a detached ADU. However, if a homeowner wants to increase square footage in the most cost-efficient manner, this ADU is a great choice.
Interior Conversion
‘Basement apartment’ or ‘mother-in-law unit’ are a couple of the many names for this ADU, created when an attic, basement or other interior space is converted into a dwelling unit (a bit less common in California).
A couple of the benefits of an interior conversion are privacy, no new construction and permits are convenient and easy to get.
