ADUs and the Changing St. Petersburg Housing Landscape
Accessory dwelling units have given St. Petersburg homeowners new options for how they use their property. In 2019, the St. Pete City Council approved legislation addressing housing affordability concerns, allowing detached accessory structures to be built on smaller property footprints than previously permitted. That change gained more attention once the pandemic prompted many residents to reconsider how their homes could be optimized for added space or income.
Sun Ray Builders, an ADU contractor serving the St. Petersburg area, has seen increased interest from homeowners exploring detached garage apartment construction and similar projects. Properties once considered too small for additional structures may now qualify under the updated zoning allowances. The rise of short-term rental platforms has added further motivation for homeowners considering a backyard cottage or in-law suite as a potential income source.
Common Questions About ADU Construction
Homeowners considering a project with an accessory dwelling unit builder often have similar questions about benefits, costs, and zoning requirements.
Benefits of building an ADU can include additional living space for family members, a separate rental unit for long-term or short-term tenants, private guest accommodations, or a dedicated space such as a home office or studio. A detached garage conversion or new garage apartment can also provide covered parking in addition to usable living space above.
Cost considerations vary significantly depending on scope. Factors such as demolition, excavation, electrical work, and the level of finish all affect the final price. As a general reference, Sun Ray Builders has typically seen per-square-foot costs for ADU construction start around $250, covering permits, materials, labor, and supervision—excluding architectural drawings. More detailed finishes or higher-end materials can push that figure to $400 or more per square foot.
Zoning restrictions remain an important part of the planning process. Even with updated legislation, properties must meet minimum size and setback requirements, which can vary by neighborhood. The City of St. Petersburg also requires that any new accessory dwelling unit reflect the architectural style of the main home, a detail that must be addressed in the permitted drawings. Parking requirements and lot coverage limits are additional factors that a detached ADU builder needs to account for during design.
Sun Ray Builders works with homeowners throughout neighborhoods such as Old Northeast, Euclid St. Paul’s, Crescent Lake, Crescent Heights, Jungle Prada, and Snell Isle to navigate these requirements as part of the design and permitting process.
Types of ADU Projects
Beyond detached garage apartments, there are several other types of accessory structures homeowners in St. Petersburg may consider:
- In-law suite: A standalone living space, often under 500 square feet, that can function as a studio or a larger one-bedroom layout.
- Pool house: A structure that can serve as an entertaining space or double as additional guest accommodations.
- Garage: A detached one-car, two-car, or hybrid structure for additional storage or parking needs.
- Backyard studio or flex space: A separate structure for hobbies, work, or relaxation, located apart from the main home.
- Outdoor entertainment structures: Detached kitchens, dining areas, or entertainment spaces built to extend outdoor living.
