Why Build an ADU?

Accessory Dwelling Units are one of the smartest investments homeowners can make.

💰

Rental Income

Earn $1,000-$4,000+ per month in rental income depending on your market. Many homeowners cover their entire mortgage payment with ADU rent.

🏠

Property Value

ADUs typically increase property value by $100,000-$300,000 — often more than the construction cost. A smart investment that pays for itself.

👪

Housing Flexibility

House aging parents, adult children, or guests. Use it as a home office. The flexibility of an ADU adapts to your life as it changes.
