Doesn't look like it's required for buildings other than dwelling units. This is from the NC Plumbing Code:
607.1 Where required. Each dwelling unit shall be provided with an adequate source of hot water for each family unit to meet minimum basic requirements for health, sanitation and personal hygiene. Central water heating facilities shall be accessible for emergency maintenance without entering any individual apartment or living unit when supplying hot water to that unit. In other occupied structures hot water may be supplied to all plumbing fixtures and equipment utilized for bathing, washing, culinary purposes, cleansing, laundry or building maintenance.

Since it says "may" not "shall" it looks like you won't need it.
Google is your friend BTW. I found it in about 1 minute and I don't even live in NC.
EDIT: Since the NC Plumbing Code is the 2009 International Plumbing Code plus some amendments, this is what the 2009 IPC says:
SECTION 607
HOT WATER SUPPLY SYSTEM
607.1 Where required. In residential occupancies, hot water
shall be supplied to all plumbing fixtures and equipment utilized for bathing, washing, culinary purposes, cleansing, laundry or building maintenance.
In nonresidential occupancies, hot water shall be supplied for culinary purposes, cleansing, laundry or building maintenance purposes. In nonresidential occupancies, hotwateror tempered water shall be supplied for bathing and washing purposes. Tempered watershall be supplied through a water temperature limiting device that conforms to ASSE 1070 and shall limit the tempered water to a maximum of 11O°F (43°C). This provision shall not supersede the requirement for protective shower valves in accordance
with Section 424.3.
