With the cost of living skyrocketing and housing shortages becoming a pressing issue, Accessory Dwelling Units (ADUs) are emerging as a game-changer for homeowners in San Diego. Whether you’re looking to generate rental income, accommodate family members, or boost your property’s value, building an ADU could be one of the smartest investments you make.
In this guide, we’ll break down what an ADU is, why they’re gaining popularity in San Diego, and how you can build one on your property.
What is an ADU?
An Accessory Dwelling Unit (ADU) is a self-contained residential unit built on the same lot as a primary home. It comes with its own kitchen, bathroom, and living space, making it a fully independent living area. Unlike traditional home additions, ADUs offer a cost-effective and flexible way to maximize space and create additional housing.
Types of ADUs in San Diego
If you're considering adding an ADU to your property, it's important to know the different types available:
✅ Detached ADU – A standalone unit separate from the main house (commonly called a "backyard home").
✅ Attached ADU – Connected to the existing house, often as an extension.
✅ Garage Conversion – Turning an unused garage into a livable unit.
✅ Junior ADU (JADU) – A compact unit (under 500 sq. ft.) created from an existing part of the home, such as a spare bedroom.
Why Are ADUs So Popular in San Diego?
