Chimney Inspection Levels 1, 2 & 3 Explained
The 3 Levels of Chimney Inspection
The National Fire Protection Association (NFPA 211) defines three levels of chimney inspection, each progressively more thorough. Understanding these levels helps you know exactly what you're getting — and what you actually need.
Level 1 Inspection — Annual Safety Check
A Level 1 inspection is the standard annual checkup recommended for all chimneys. It examines readily accessible portions of the chimney exterior, interior, and accessible portions of the appliance and chimney connection.
What's included:
- Visual examination of chimney exterior (brick, mortar, crown, cap)
- Firebox inspection
- Damper operation check
- Basic flue assessment from above and below
- Verification that chimney is structurally sound and free of obstructions
When you need it: Annually for all chimneys, even if unused. Cost in Seattle: $149-$199.
Level 2 Inspection — In-Depth Assessment
A Level 2 inspection includes everything in Level 1 plus HD video camera inspection of the entire flue interior, accessible areas of the attic and crawl spaces, and comparison against applicable building codes.
What's included:
- Everything in Level 1
- HD video camera scan of entire flue interior
- Inspection of accessible attic and crawl spaces around chimney
- Evaluation of chimney clearances to combustibles
- Detailed written report with HD photos
- Assessment against current building codes
When you need it:
- Buying or selling a home
- After a chimney fire or seismic event
- Changing fuel type (wood to gas or vice versa)
- After any significant weather event
- When problems are suspected
Cost in Seattle: $249-$399. This is the most commonly requested inspection level.
Level 3 Inspection — Invasive Investigation
A Level 3 inspection includes everything in Levels 1 and 2 plus removal of building components to access concealed areas. This may involve removing drywall, siding, or chimney crown material to assess hidden damage.
When you need it:
- Serious structural hazard suspected
- Major chimney fire investigation
- Severe seismic damage assessment
Cost in Seattle: Custom quote (depends on scope of access needed). Level 3 inspections are rare and only recommended when serious concealed hazards are suspected.
