Accessory Dwelling Units (ADU)

The State of California passed legislation allowing landlords and homeowners to build Accessory Dwelling Units (ADU). Dwelling units range from fully detached homes, existing structures and garage conversions into habitable and leasable spaces. We have completed and specialized in ADU Projects throughout Southern California with contractors, engineers and financing specialist to assist property owners to completion with estimates, permits and construction.

Multifamily Residential ADU Benefits:

  • Increase the amount of rentable units in an apartment complex.

  • Provide a means for passive income for single family homes.

  • Increase property value.

  • Local agencies must allow up to two new constructed Detached ADU and/or Multiple ADU within the portions of multifamily structures that are not used as livable space, such as attached garages. Maximum allowable conversion units are up to 25% of the existing dwelling units.

What is an ADU?

An ADU is an accessory dwelling unit with complete independent living facilities for one or more persons with few variations:


• Detached: The unit is separated from the primary structure.
