What are ADUs?

ADU’s are what many know as Granny flat, in-law suite, converted garage, backyard cottage, basement apartment, companion units.  Regardless of the name, ADU’s are self-contained homes legally part of the same property. ADU’s can take many forms and vary in size, but always contain everything someone needs to live, including a kitchen, bathroom and a place to sleep. ADU’s typically range from 400 sqft to 1,200 sqft.

These units can be rented year-round and increase the value to a property.  Building second units (ADUs) are a relatively affordable type of construction.  With rents for a 1 bedroom 1 bathroom unit averaging $1,400/month in many areas of Southern California, many people install an ADU to help pay their primary mortgage or earn extra income.

Detached ADU

Stay classy with a variety of elegant options in all sorts of styles. Whether you want to stay simple or make a perfect match with your main home (so the ADU doesn't look like an after thought), we’ll make sure this product is built specifically to suit your needs and preferences.  Building a detached ADU offers a ton more flexibility; depending on the available space we can build as much as 1,200 sqft...  possibly more, depending on your location.
