Wind Zone
Ultimate design wind speed — verify with engineer
Snow Load
Ground snow load, minimum design
Typical Setbacks
Varies by zoning; a site plan showing building setbacks must accompany accessory-structure permit applications.

Pro Tip for Lexington County
A small detached storage shed may be exempt, but a larger or utility-served metal building isn't — bring a site plan with setbacks to Community Development so they can tell you which side of the line you're on.
