Setback Requirements in Greenville, SC (2026)

Can I build an ADU on my Greenville property?

Yes. Greenville allows accessory dwelling units (ADUs) in residential zones under the Land Management Ordinance. Detached ADUs are limited to 900 sqft. You need a Greenville Planning and Development zoning and building permit. No owner-occupancy requirement and no development impact fees. Rear setback is 5 ft and side setback is 5 ft for detached ADUs. Apply online through https://aca.greenvillesc.gov/ — build timelines may be affected by Greenville's rapid construction pace.

What makes Greenville's growth so significant for housing?

Greenville has been one of the fastest-growing cities in the Southeast for over a decade, driven by BMW's North American headquarters, Michelin (whose global operations center is nearby), major healthcare expansion, and a nationally recognized downtown revitalization centered on Falls Park. 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.

Are short-term rentals (Airbnb) allowed in Greenville?

Yes. Greenville requires an STR registration ($100/year) with Greenville Revenue Services. There is no primary-residence requirement in Greenville's STR rules. 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.

What are the solar incentives available in Greenville?

Greenville solar owners benefit from South Carolina's net metering (retail-rate credit from Duke Energy for excess generation), the Federal Investment Tax Credit (30% of system cost), and South Carolina's 25% state solar tax credit (capped at $3,500). Greenville averages 207 sunny days per year, providing good production. Duke Energy's interconnection process serves Greenville. Permits are straightforward — apply with Greenville Planning and Development. South Carolina's combined incentives (federal ITC + state credit + net metering) make Greenville solar economics among the better in the Southeast.

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.
