What Is the NFPA 211 Standard for Chimney Inspections?
The National Fire Protection Association (NFPA 211) standard establishes three standardized inspection levels (Level 1, Level 2, Level 3) to evaluate chimney soundness, draft clearance, creosote deposits, and flue liner integrity.
Standard home inspectors examine chimneys only from the ground or roofline, focusing on external brick and hearth appearance. They cannot see internal clay tile joints or hidden structural fractures inside the walls. A chimney inspection uses specialized video camera equipment to record the entire vertical flue run, identifying hidden carbon monoxide hazards and determining whether stainless steel relining or masonry tuckpointing is required.
