Alleghany County, NC Permits for Metal Carports and Garages

Most metal carports, garages and barns in Alleghany County need a permit, because the fee schedule says utility buildings over 400 square feet, or longer than 12 feet on one side, need one.

Zoning and setbacks

The county planner handles floodplain management, subdivisions, ridge development and watershed protection. If your lot is in a flood zone, along a ridge or in a watershed area, ask about those rules before you build. If you have a septic system, the county's owner packet includes Appendix H, an affidavit about your existing wastewater system and its setbacks, for garages and utility buildings. Ask the office what distance from property lines they want to see.

What to bring

Building Application (check the Garage/Carport or Utility Building box)
Owner packet with the Owner Exemption Affidavit if you are building it yourself, or the Contractor packet
Appendix H wastewater system affidavit for a garage or utility building
Building plans, or engineered drawings for a certified metal building (we can help you get these)
Erosion control plan if the application's questions call for one

Farm buildings

A building used only for a bona fide farm may be exempt from a building permit in county jurisdiction under N.C. G.S. 160D-903. Ask Planning & Inspection what proof of farm use they want to see. Electrical work still needs a permit.

Good to know

Forms and the fee schedule are on the county's online forms page. The office has a notary on staff for forms that must be notarized. For septic or well questions, Appalachian District Health Department in Sparta is at 336-372-5641. This is mountain country, so ask about the snow load to design for.
