Do I Need a Permit for Chimney Repair? in United States
Minor chimney maintenance like tuckpointing, cap replacement, or flashing repair rarely requires a permit. However, structural chimney work — rebuilding the chimney above or below the roofline, relining the flue, modifying the chimney height, or changing the fireplace/appliance connection — typically does. When in doubt, call your local building department: the call is free and clarifies whether your scope needs a permit.

Country-specific detail
US permit requirements vary by scope. Tuckpointing, crown repair, cap installation, and flashing repair are generally exempt. Rebuilding the chimney (above or below roofline), relining the flue, and any work involving gas appliance connections typically require a permit and inspection. The IRC (International Residential Code) Chapter 10 governs chimney construction, and local fire marshals may have additional requirements for flue relining or fireplace modifications.
