Yes. Wake County and the City of Raleigh both require a building permit for any work that alters the load path: removing or modifying load-bearing walls, cutting new door or window openings in exterior walls, adding a second story, altering roof framing, or replacing floor joists and beams. Cosmetic drywall, flooring, and paint do not require a permit; structural changes always do.

Any change to the load path: removing walls, adding openings, replacing beams or joists, altering rafters and trusses, adding a story or dormer, and most foundation repairs (helical piers, push piers, wall reinforcement).
Additions and finished attics also require structural review even if the exterior footprint doesn't change, because you're adding load the original framing may not have been sized for.
For load path changes, Wake and Raleigh reviewers require a PE-stamped drawing showing beam sizing (species, grade, dimensions), post and footing details at each end, and a clear load path from the roof down to the foundation. Sketch-only submittals get rejected.
For foundation repair permits, they want the pier layout, capacity, and manufacturer specs on a stamped plan, plus soil bearing assumptions.
