Accessory Dwelling Units (ADU)

Accessory Dwelling Units, also known as ADU’s, are dwellings–either attached or detached from a main house–that exist on a lot with another house.  ADU’s are a way to provide housing in markets where prices have skyrocketed.  These small dwellings are a way for homeowners to host short-and long- term renters while continuing to live on site. 


Top Uses for ADU

  • Personal Housing

  • In-Law Suite

  • Home for adult children

  • Rental Income

  • Home Office


Top Reasons to build an ADU vs Buying a Home

  • Reduce Expenses

  • Decreased Maintenance

  • Little or No Debt

  • Self-Sufficiency

  • Reduced Carbon Footprint

  • Small enough to fit on smaller inner city lots and large estate properties

  • Turn-key solutions (design & construction)


Various Types of ADUs

Since ADUs can be created in many different shapes and styles, they are able to fit discreetly into all sorts of communities, including suburban subdivisions, row-house streets (either with or without back alleys), walk-able town or urban neighborhoods – and, of course, large lots and rural regions.


Detached ADU - Is a stand-alone home on the same lot as a larger, primary dwelling.   Examples include backyard bungalows and converted outbuildings.


Attached ADU- Connects to an existing house, typically through the construction of an addition along the homes side or rear.  Such units can have a separate or shared entrance.

Internal ADU-is created when a portion of an existing home – an entire floor, part of a floor, or an attic or basement – is partitioned off and renovated to become a separate residence.

ADUs in California

“California passed historic ADU legislation with AB 68.  “Under AB 68, homeowners who apply to build accessory dwelling units or “granny flats”, can also apply to build a second, “junior” ADU on their property – the functionality equivalent of statewide triplex zoning.  While the new rules don’t allow the subdivision of properties for sale, they could unleash a “golden age” of ADU construction across the state leading to a significant increase in housing supply” – California YIMBY


“The passage of AB 68 […] fundamentally shift the landscape for building new homes in our state” Brian Hanlon, co-founder and president of zoning reform advocacy group California YIMBY said via press release, adding, “When the Governor signs these bills into law, almost every residential property in the state will be allowed to build three units of housing – including in areas zoned for single family homes.”
