Accessory Dwelling Units in California
Custom-built ADUs designed for comfort, flexibility and long-term value.
Custom-built ADUs
An Accessory Dwelling Unit is a second, fully self-sufficient home on a residential lot, with its own bathroom, living area and working kitchen.
In California, ADUs are a key part of the solution to the housing crisis. Whether it's a rental unit, a guest house or a home for extended family, an ADU is a legal, practical way to add livable space without buying more property.
Immediate and long-term advantages
Rental income
With rising housing demand across California, an ADU can generate steady monthly income from tenants seeking homes in desirable neighborhoods.
Multigenerational living
A perfect solution for aging parents, young adults returning home or long-term guests: privacy and independence, with loved ones close.
Increased property value
Homes with legal, well-designed ADUs can sell for significantly more than comparable properties without them.
Flexible use
A home office, short-term rental, art studio or caregiver suite, and it can change with your needs over time.
Favorable state laws
California laws such as SB 9, AB 2221 and SB 897 relax zoning restrictions, remove minimum lot sizes and speed up approvals.

What our clients say
Creation 7 was absolutely fantastic to work with for our addition and remodel project. They were not only our builders for the project, but they also did our design. Eyal and his team had an incredible eye for the architecture design of the build as well an impeccable attention to detail.
One of the things we value most about the Creation 7 team is they committed to a timeline up front and delivered on it.
We hired Creation 7 to build our home office + gym. They were right on time. Job was done while environment always clean and neat. Didn't feel anyone even working around the house. Project was completed within the agreed budget and timeline.
It really was a pleasure as Creation 7 has done an excellent job with attracting high quality, friendly and conscientious construction workers that have an eye for details.
Eyal, Avi and the entire Creation 7 team is a joy to work with. They are true professionals and do the highest quality through work. It is such a relief to have found a company that is trustworthy, on time, efficient, approachable and kind like Creation 7.
