If you’ve noticed more homeowners in St. Petersburg adding backyard cottages, garage apartments, or in-law suites, you’re seeing the rise of ADUs. Accessory Dwelling Units (ADUs) are small, secondary homes built on the same property as a primary residence, and they’re becoming one of the most popular housing options in the city.
What Exactly is an ADU?
An ADU is a fully functional living space with its own kitchen, bathroom, and entrance. In St. Pete, they can take different forms, such as:
- Detached cottages in the backyard
- Garage apartments above existing structures
- Quite office space away from home distractions
Why St. Pete Homeowners are Building ADUs
There are plenty of reasons ADUs are growing in popularity:
- Rental Income: Many homeowners use ADUs as long-term rentals or Airbnb properties to offset mortgage costs.
- Family Flexibility: They make great living spaces for aging parents, adult children, or visiting guests.
- Property Value: Adding an ADU increases square footage and boosts resale potential.
- Community Growth: ADUs also help address St. Pete’s growing demand for more housing options.
