Accessory Dwelling Units
Add space, value, and income potential to your property with a custom-built ADU in North County San Diego.
What Is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. Also known as granny flats, in-law suites, or backyard cottages, ADUs are fully self-contained living spaces with their own kitchen, bathroom, and entrance. California law has made it easier than ever to build one on your property.
Rental Income
Generate passive monthly income by renting out your ADU. San Diego's strong rental market makes this a smart investment.
Increased Property Value
An ADU can boost your property value by 20-30%. It's one of the highest-ROI home improvements you can make.
Multigenerational Living
Keep family close while maintaining privacy. Perfect for aging parents, adult children, or extended family.
Home Office
Create a dedicated workspace separate from your main house. Perfect for remote work, creative studio, or consulting practice.
