From planning and permits to construction and financing, this guide covers everything you need to know—ensuring your project runs smoothly from start to finish.
What Are ADU Works?
ADU works refer to the entire process of designing, permitting, and constructing an Accessory Dwelling Unit on a residential property. These secondary units can be detached (backyard cottages), attached (garage conversions), or interior (basement apartments). The process involves multiple steps, including zoning checks, architectural planning, securing permits, and hiring skilled builders.
Since many cities have eased ADU work regulations to combat housing shortages, now is an excellent time to invest in one. Whether you want extra income, a home office, or a private space for aging parents, ADUs offer flexibility and long-term value.

An ADU can generate 1,500–3,500/month in rental income, depending on location and size. This makes it a smart financial move for homeowners looking to offset mortgage costs.
2. Increased Property Value
Homes with ADUs typically see a 10–30% boost in resale value, making them a worthwhile investment.
3. Multigenerational Living
ADUs provide privacy while keeping family close—ideal for aging parents, adult children, or guests.
4. Affordable Housing Solution
With rising home prices, ADUs offer a cost-effective way to expand living space without moving.
5. Flexible Usage
