Thinking about adding an ADU to your property in St. Petersburg? Whether you’re planning a backyard cottage for family or a rental unit for extra income, the first steps can feel overwhelming.
The good news: with the right guidance, starting your ADU project is simpler than you think.
Step 1: Understand the Rules
Before you dive into design ideas, check the City of St. Petersburg’s ADU requirements. Zoning, lot size, and maximum square footage (up to 800 sq. ft.) all play a role in what you can build.
Step 2: Define Your Goals
Ask yourself:
- Is this ADU for family, guests, or rental income?
- Do you want it attached to your home or fully detached?
- How will it complement your property’s overall design?
- What’s the intended purpose of the space?
Having clear goals helps shape the design and budget.
Step 3: Plan Your Budget
ADUs are an investment but one that can increase property value and provide income opportunities. Work with a contractor who can give you a realistic estimate and help you plan financing options.
Step 4: Partner with the Right Builder
Building an ADU means navigating permits, codes, and construction. Partnering with an experienced local builder ensures your project runs smoothly from start to finish.
