Population growth has put significant pressure on Greenville's housing supply. ADUs, infill development, and mixed-use zoning are key strategies in Greenville's Housing Diversity Plan to maintain affordability amid rapid growth.
How does South Carolina's cottage food law work in Greenville?
South Carolina's Cottage Food Law allows home-based production and direct sale of baked goods, jams, jellies, and similar shelf-stable foods without a full restaurant license. There is no annual revenue cap in South Carolina's law. For sales under $15,000 per year, only DHEC registration is needed (no full permit). Above $15,000, a DHEC cottage food permit is required. Greenville's TD Saturday Market at Fluor Field and Saturday Market at Falls Park are popular venues for cottage food sales. Contact SC DHEC at scdhec.gov for current permit requirements.

You must designate a contact person for complaint response and comply with housing maintenance standards. South Carolina state sales tax (5%) and Greenville County hospitality taxes apply — Airbnb collects these. Greenville's growing tourism industry (BMW Performance Center, Bon Jovi concerts at Bon Secours Arena, TD Saturday Market) generates year-round STR demand.

Does Greenville have flooding risk for development?
Greenville has localized flood risk along the Reedy River and its tributaries — particularly in and around the Falls Park area and adjacent neighborhoods. While Greenville lacks coastal storm surge risk (unlike Charleston), intense Upstate thunderstorms can cause rapid creek flooding. Properties adjacent to the Reedy River floodplain must comply with FEMA flood zone standards. Greenville has invested significantly in Reedy River greenway infrastructure that also serves as flood mitigation. Check the FEMA Flood Map Service Center for your property's flood zone before construction.
