Why Build an ADU?
Unlock Your Property's
Full Potential.
An Accessory Dwelling Unit is the single highest-value cosmetic and structural upgrade you can make to your California property. Here is why homeowners are building:
- Create a Monthly Rental Cash Flow
Generate stable passive income ($1,800 - $3,500+ depending on market) by renting your ADU to long-term tenants or travel nurses.
- Multigenerational Housing Options
Keep aging parents or adult children close while maintaining independent living zones, private entries, and structural boundaries.
- Design a Quiet Work-From-Home Oasis
Stop working at the dining table. A detached ADU makes a professional home office, creative art studio, personal gym, or pool house.
- Maximize Home Equity & Value
California zoning laws permit backyard cottages. Building stick-built ADUs adds real square footage and boosts total property valuation.
