Remarks & Misc

Remarks – Consumer: New commercial property with excellent highway visibility, Suburban Commercial Zoning, flexible use potential, and room for expansion. Located across three platted lots with 100 feet of highway frontage, the property offers strong exposure from both directions and is ideal for an owner-user, investor, or business seeking a visible commercial location. The 2,600-square-foot CBS building features a concrete roof, 12-foot ceilings, and CGI impact-rated windows and doors. The layout includes eight individual bays and a separate office/retail space. Each bay has a Janus hurricane rated roll-up door measuring approximately 8'8''W x 9'H, providing convenient access for deliveries, equipment, inventory, or personal car storage use. The office/retail area includes natural light, coral columns, Hardy Board siding, quality exterior finishes, and a dedicated bathroom. The reinforced concrete roof was engineered with the strength to support a potential second-floor addition, with a higher live-load capacity. All additions would subject to zoning, permitting, and county approvals. Since the building occupies only one of the three platted lots, the remaining land may offer additional development or expansion potential. Additional features include a dedicated irrigation meter, a separate water supply meter, and two street access points. Building and property are offered for sale only; the existing business is not included. Interior photos are available upon request. See SC Zoning uses in Document tab for all permitted and conditional property uses.
