Ultimate design wind speed — verify with engineer

Snow Load

5 psf

Ground snow load, minimum design

Typical Setbacks

Varies by zoning; coastal flood-zone and wind-borne-debris provisions also affect placement and anchoring.

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.
