Together with the State of California, We are Trying to Make Housing Affordable to Everyone.

American Institute of Architects

A brief history

(Andrew) Nghia Nguyen, the principal architect, started CA2homes in 2013 as his side job after 13 years working for contractors and architectural firms in the Bay Area and overseas.

CA2homes focuses on single-family residences (houses) both remodel and new construction. 

CA2homes has designed and got permits for many ADUs in San Jose and its surrounds. 

Our first fully customized and luxurious ADU was approved and built in Monte Sereno back in 2015 when ADU was not allowed without providing an additional garage.

The next year 2016, our first San Jose's ADU was approved and built under the newly effective SB 1069 (Yeah! no parking required!). See our log here: https://www.facebook.com/photo/?fbid=1753672318214639&set=pcb.1753674094881128

As an architect licensed in the State of California, we feel to be responsible to make housing affordable to more people and to fight the housing crisis. UniADU.com was born in June 2023 thankfully to the City of San Jose's help and encouragement made the process smooth and straightforward.

Our Custom ADU

Where we are today

We have got permits for many custom ADUs, detached or attached in the South Bay Area.

We designed one of the first ADUs built under the new law in San Jose.

We designed the first SB9 project in San Jose.

We are listed on the City of San Jose for pre-approved ADU plans ready for permits.

We are highly recommended by our clients.
