Leading Design and Engineering for ADUs, Garage Conversions, Multi-Family ADUs and JADUs
Accessory Dwelling Units (ADUs)

ADUs are a secondary dwelling unit with complete independent living facilities for one or more persons. Up to 1200 Sq.ft of additional space can be added to your home with an ADU. They are an innovative, affordable, effective option to increase the value and space of your home. Today ADUs are known by different names: granny unit, granny flat, in-law unit, in-law cottage, mother-in-law apartment, sidekick home, laneway home, backyard guesthouse, backyard cottage or secondary dwelling unit. ADUs are affordable in California as they do not require paying for land, major new infrastructure, structured parking, or elevators. Further can provide an additional source of income for homeowners.

Multi- Family ADUs

New ADU Law for Multi-Family Buildings Launched in Jan 2020

The first time, the new ADU laws launched in January 2020 allow units to be added ADUs and JADUs to your existing multifamily buildings. All Cities in California must permit these types of units in multifamily buildings without applying any local development standards.

What is JADU?

A Junior ADU (or JADU) is a new category of dwelling units created by the State of California. The main difference is that a JADU is not required to have a dedicated bathroom.

  • Architectural Plans for ADUs

    The first step of creating an ADU is to have an architectural plan. If you do not have a plan handy, we are happy to connect you with one of our trusted Architect partners in your area. Our partner architects specialize in various architectural styles and can create an Architectural Permit set for any design styles you have in mind.

  • Engineering Services for ADUs

    We have you completely covered when it comes to the engineering required for the ADU. Our engineers can take your ADU vision and iron out the details to ultimately create the ADU plans for construction. We then work with you across the ADU construction and oversee every step of the project.
