Why Accessory Spaces?

Less hassle

Building an ADU is a full-time job. We schedule the appointments, deal with contractors and work through the nitty-gritty of your ADU--so you don't have to.

ADUs are our specialty

We only do ADUs and second units. Our team has 10+ years in construction and permitting. We know how to get it done. 

Our process


We work with your preferred lender or with one of ours to get you qualified for the loan to build your ADU.


We'll guide you and introduce you to professional designers, architects and engineers to prepare the construction plans.


We are at the city for the permitting process and will push the permits along to constuction.


We oversee the general contractor, manage time schedules, materials, and quality. While making sure to stay within budget.


We guide you from unit maintenance to tenant management.
