Metal Building Permits in Horry County, SC
Planning a barndominium, steel garage, workshop, or agricultural building in Conway or anywhere in Horry County? Here's what to expect on permits, setbacks, wind and snow loads, and HOA rules — plus a free, permit-ready quote from AAIRE Co.
Permit Required
Horry County Code Enforcement issues building permits and inspects new construction in the unincorporated county; coastal wind design and wind-borne-debris rules apply, and requirements increase closer to the coast.
Wind Zone
Ultimate design wind speed — verify with engineer
Snow Load
Ground snow load, minimum design
Typical Setbacks
Varies by zoning; coastal flood-zone and wind-borne-debris provisions also affect placement and anchoring.
HOA Risk
High — the Myrtle Beach/Grand Strand area is dense with HOA and POA communities that regulate or prohibit metal accessory buildings; inland Conway/Aynor areas are more flexible.
Pro Tip for Horry County
Wind requirements jump as you near the ocean — a building within a mile of mean high water hits the highest zone (up to ~150 mph), so confirm your site's design wind speed with Code Enforcement before ordering steel.
