Across Southern California, homeowners are sitting on untapped opportunity. Garages, backyards, and unused space often go underutilized while housing demand continues to grow and the cost of living rises.​

 

At the same time, building an ADU independently can feel overwhelming. Between project costs that often exceed $200,000 and the complexity of permits, design, and construction management, creating rental income from your property can feel out of reach for many homeowners.

​

Twenty-One Six was created to change that.​

 

We partner with homeowners to transform unused space into thoughtfully designed backyard homes that generate steady rental income , without requiring homeowners to take on construction costs or development headaches or the woes of managing a property.

​Our focus isn’t just building units. It’s creating modern, well-designed homes people genuinely want to live in.

​

By handling design, permitting, construction, and delivery, we make it simple for homeowners to turn unused space into meaningful passive income while helping address the growing need for well-designed rental housing.​

 

Twenty One Six was founded on a simple belief: homeowners shouldn’t need to move or take on debt to create financial freedom from the property they already own; and we’re excited to help homeowners unlock the opportunity that is already sitting in their backyard.
