The property falls under RG-1 zoning with a future land use designation of Residential Coastal (Res-C), allowing up to four units per acre. Neighboring parcels have capitalized on this potential with four townhomes each. This lot may be subdivided to accommodate an additional main dwelling or, without subdivision, an accessory family unit can be added—confirmed in writing by St. Johns County (attached in documents). Located just behind the oceanfront row of homes on a quiet street, this rare offering combines immediate coastal living with long-term development potential—ideal for a family retreat, an investment, or both.
