Accessory Dwelling Units

An accessory dwelling unit, usually just called an ADU, is a secondary housing unit on a single-family residential lot. The term “accessory dwelling unit” is a institutional-sounding name, but it’s the most commonly-used term across the country to describe this type of housing. While the full name is a mouthful, the shorthand “ADU” is better.

The Jose family, of residential Atherton, had always wanted to build a separate living space for their mom to care for. After talking to us, we recommended a split ADU based on their family’s usage needs and square footage, city codes and various specifications. we then visited the Jose family at home, took extensive measurements on site, and discussed in detail with the Jose family about their ideas for their dream house. we drew up some inspirational plans on site and won their favor. During the subsequent design process, we maintained weekly communication with the Jose family about the current work progress and ideas, and resolved the collision of inspiration and regulations in the design step by step. Jose was thrilled to say, “This is the house we wanted, thank you so much”. This made our engineers feel proud of their professional services. Let’s take a look at Jose’s dream house

Thanks to AB 68, homeowners that turn their garages into ADUs (or knock the garage down to build an ADU from scratch) no longer have to replace the lost parking spaces.

Additionally, there is now no parking spot requirement at all for units built within half a mile from public transportation. Around LA, it’s rare that some place isn’t within a half mile of some kind of public transport.
