What is an ADU & Why St. Pete Homeowners are Building Them

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.

Before you build, you’ll need to check zoning rules, size limits, and design requirements. At CASK Construction, we help homeowners navigate the process from permits to final build,  making sure your ADU meets city regulations and fits your lifestyle needs.
