The answer is ALMOST ALWAYS!

The North Carolina State Building Code states, "No person, firm or corporation shall erect, construct, enlarge, install, alter, repair, move, improve, remove, convert or demolish any building, structure, or service system without first obtaining a permit for such from the Inspections Department having jurisdiction."

In other words, a permit is required anytime work is done on a building or structure, or the systems serving the structure (including plumbing, mechanical and electrical wiring) with a few exceptions.

Examples of everyday projects requiring permits include:

• Converting a residence to a business.
• Constructing a deck, screened porch, or sunroom.
• Installing an irrigation system.
• Installing a swimming pool.
• Adding a ceiling fan.
• Finishing an attic or basement.
• Replacing a furnace or air conditioner.
• Replacing water heaters.
• Installing gas logs, attic fans, skylights

A permit is not required for:

• Replacement of non-structural, cosmetic building elements, such as: floor and wall coverings; moldings and trim; cabinets and casework; roof coverings with same materials, etc.
• Residential storage buildings that 12' x 12' or less.
• Replacement of electrical fixtures and components when work done within the wall or ceiling cavity or behind the finished wall or ceiling surface.
• Replacement of plumbing fixtures when the work goes beyond the trap seal.
• Installation of low voltage exterior landscape lighting

Yes. The Town of Coats UDO does limit fence height and material.  A permit should be done to ensure that the fence does not obstruct any access or utility easements.
