From the listing

RARE REDEVELOPMENT OPPORTUNITY ON A LARGE ST. PETERSBURG LOT! Situated on an expansive lot in an established South St. Petersburg neighborhood, this property presents an excellent opportunity for buyers looking to renovate, reimagine, or explore future redevelopment possibilities. The existing property includes a vintage brick single-family residence and detached garage with substantial paved parking/drive area, offering a unique footprint and flexibility not commonly found in the area. The existing home and detached garage are being offered AS-IS and will likely require significant renovation if retained. For the investor, builder, or developer, the size and configuration of the site create an opportunity to investigate alternative uses, including potential redevelopment or reconfiguration of the property, subject to verification of zoning, land-use regulations, lot-split/subdivision requirements, site-plan approval and all applicable City of St. Petersburg requirements. The property is located in an area experiencing continued investment and redevelopment, making this an especially compelling opportunity for those looking beyond the existing structure and evaluating the land and its future potential. Buyers and their agents are encouraged to independently verify zoning, allowable density, subdivision potential, development standards, utilities, setbacks, and all other information with the City of St. Petersburg and applicable authorities.
