Property Description
HIGH AND DRY! NOT IN A FLOOD ZONE! Welcome to the brick-lined streets of St. Petersburg, where neighborhood charm, waterfront recreation, and easy access to downtown come together. This unique property features a 2-bedroom, 1-bathroom main home plus a detached 1-bedroom, 1-bathroom ADU, offering incredible flexibility and potential rental income. A spacious front deck provides a welcoming place to relax beneath the shade of mature trees. Stepping inside the main home, abundant natural light and wood-look flooring flow throughout the living and dining spaces. The kitchen offers ample cabinetry and countertop space, stainless steel appliances, and recessed lighting. Both bedrooms are a comfortable size and share a full bathroom. Outside, the vinyl-fenced property creates a private retreat with an expansive pavered courtyard connecting the main residence to the detached ADU. A large rear gate provides private alley access for conveniently parking a vehicle or storing a boat, while still leaving ample yard space to enjoy. The property also includes a storage shed for tools, recreational equipment, and additional belongings. The separate dwelling features its own living space, kitchen, bedroom, and full bathroom with a walk-in shower. Additional highlights include newer roofs on both the main home and ADU, along with newer pavers, windows, front deck, and more. Just blocks from the Tampa Bay waterfront, residents can enjoy morning walks, kayaking, or sunset picnics across the 14-acre green space at beloved Lassing Park. Downtown St. Pete is only minutes away, placing waterfront dining, local coffee shops, museums, Tropicana Field, the St. Pete Pier, USF St. Petersburg, and the vibrant Central Avenue corridor within easy reach. With convenient access to I-275, area hospitals, and Gulf beaches, this is a rare opportunity to enjoy one of St. Pete's most character-filled neighborhoods with the versatility of two separate residences.
