Benefits of ADUs



ADUs are affordable because they do not require paying for land, major new infrastructure, structured parking, or elevators.



ADUs are built with cost-effective wood frame construction, which is significantly less costly than homes in new multifamily infill buildings.

Extra Living Space

ADUs can provide as much living space as many newly-built apartments and condominiums, and they’re suited well for couples, small families, friends, young people, and seniors.

Passive Income

We’re helping homeowners in Los Angeles earning averagely $2,500 a month by building their ADUs which are turned into residential units.



ADUs allow extended families to be near one another while maintaining privacy.


ADUs give homeowners the flexibility to share independent living areas with family members and others.

ADU Los Angeles

Once rented, you add substantial extra monthly income. That income will in most cases be greater than the costs of the payment for on a construction loan for your ADU. Furthermore, you are adding significant long-term resale value to your property.

ADU Los Angeles development is not something that the state would or should mandate. But if you are a Los Angeles and surrounding areas homeowner, by developing an ADU you are not only investing in yourself, but also helping the affordable housing crisis and stimulating the economy.
