We will help you get to the pot of gold at the end of the rainbow as fast as possible: generating more passive income or just building additional living space in your home.

There are four kinds of ADUs we can build

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.

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.

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).

At OakADU, we will make sure the permit gets approved without those extremely costly delays that can turn any project into a nightmare and destroy a budget. We make sure that you don’t end up with a project that drains your bank account without adding significant value to your home. We work with some of the best architects in California on our projects, which is why we can get you a world-class design for a reasonable cost. No one will build you a more beautiful ADU than the team at OakADU!
