There are three defined chimney inspection levels under CSIA and NFPA 211 standards. They’re not different prices for the same thing, they’re different inspections, designed for different situations. Knowing which one you actually need saves you money and gets you the right documentation.

Level 1: annual safety check

A Level 1 inspection covers accessible portions of the chimney, fireplace, and flue, plus a check that the system is appropriate for the appliance it serves and that there’s no obvious damage.

What’s included:

  • Visual exterior inspection from the ground (and roof if accessible)
  • Interior inspection of the firebox, smoke chamber visible from the firebox, and flue visible from the firebox or top
  • Damper operation check
  • Cap, crown, and flashing condition assessment from the roof
  • Combustible clearance verification at the firebox
  • Written report with photos and clear pass/repair recommendations

What it’s for:

  • Annual maintenance check on a system you’ve used before with no changes
  • Routine safety verification before the burning season
  • Required by CSIA standards as the minimum annual inspection for any chimney venting solid fuel, gas, or oil

Pricing: $89 in San Diego County. Credited toward any cleaning that follows.

When NOT to use Level 1:

  • Pre-purchase inspection (Level 2)
  • After a chimney fire, lightning strike, or earthquake (Level 2)
  • Switching fuels, wood to gas, gas to wood, or wood to insert (Level 2)
  • After any significant exterior damage to the chimney (Level 2 or 3)

Level 2: pre-sale, post-event, or fuel change

A Level 2 inspection includes everything in Level 1 plus a full color video camera scan of the entire flue from top to bottom, an attic and basement check where the chimney passes through, and a more detailed report formatted for lenders, insurers, and real-estate disclosure.

What’s added vs. Level 1:

  • Full-length video camera scan of the flue interior, recorded for your records
  • Attic and basement inspection of the chimney where it passes through
  • Detailed inspection of the smoke chamber walls (parging, mortar joints, masonry damage)
  • Inspection of the connection between the appliance and the chimney
  • Written report formatted for lenders, insurers, and real-estate disclosure

What it’s required for (per CSIA standards):

  • Real estate transactions, most home inspectors and lenders require a Level 2 chimney inspection on any home with a fireplace or stove. This is the most common reason people hire a Level 2.
  • After any chimney fire, heat damage to flue tile is almost certain, even if the fire was small.
  • After a lightning strike, sudden expansion and electrical damage can crack flue tile.
  • After an earthquake, California requirement; visible exterior damage often hides interior cracking.
  • Fuel changes, wood to gas log set, gas to wood, gas appliance to fireplace insert. The flue sizing requirement changes with fuel type.
  • Appliance changes, installing a new high-efficiency furnace, water heater, or wood stove insert.
  • After significant building changes, adding a story, removing a wall, modifying the chimney structure.

Pricing: $249 in San Diego County. We turn around real-estate Level 2 inspections in 24–48 hours during escrow.

Level 3: partial removal where defects are suspected

A Level 3 inspection is only triggered after a Level 2 finds reason to suspect hidden defects that can’t be fully assessed without removing parts of the chimney structure.

What’s involved:

  • Selective removal of permanently attached chimney components (firebox panels, smoke chamber walls, exterior masonry)
  • Detailed inspection of areas exposed by the removal
  • Assessment of structural integrity where Level 2 raised concerns
  • Reconstruction of any removed components

What triggers a Level 3:

  • Level 2 camera scan found cracking in flue tile beyond visible inspection
  • Smoke chamber suspected of being unparged or damaged behind firebox panels
  • Suspected hidden water damage in the chimney structure
  • Investigating the cause of a serious chimney fire

Pricing: quoted after Level 2 because the scope depends entirely on what the Level 2 reveals. Typically $1,500–$5,000+ depending on what needs to be removed and reconstructed.

Most homeowners never need a Level 3. It’s specifically for forensic-level inspection of suspect chimneys.

Which level do I actually need?

Buying a home with a fireplace? Level 2. Most home inspectors will recommend it as a separate inspection from the general home inspection. Lenders increasingly require it.

Selling a home with a fireplace? Level 2 if you want to disclose with confidence. Pre-listing Level 2 inspections often pay for themselves by preventing escrow delays from buyer-side findings.

Annual maintenance on a fireplace you use regularly? Level 1.

Insurance carrier asking for a chimney inspection report? Usually Level 2, they want the full documented camera scan.

Switching from wood-burning to gas log set? Level 2. The flue sizing requirement changes when you change fuels.

Just installed a wood stove insert? Level 2 for the new appliance configuration.

You had a fire in the firebox and water came out the chimney damper afterward? Level 2. Probably extinguished a chimney fire, the flue almost certainly has heat damage.

What a written report includes

A real Level 2 report from a CSIA-certified sweep should include:

  • Cover page with inspection level, date, address, technician name, and CSIA certification number
  • Executive summary, pass / repair / urgent
  • Itemized findings with photos for each defect
  • Defects categorized as safety, structural, or cosmetic
  • Camera scan stills or full video link
  • Repair recommendations with rough cost ranges
  • Sign-off statement

If a “Level 2” inspection comes back as a one-page checklist with no photos, it wasn’t a Level 2.

Bottom line

  • Level 1 ($89): annual safety check, routine maintenance.
  • Level 2 ($249): real estate transactions, post-fire/quake/lightning, fuel changes, appliance changes.
  • Level 3 (quoted): only after a Level 2 finds reason, partial removal investigation.

When you’re not sure, default to Level 2. The extra $160 over Level 1 buys you the camera scan, the full report, and the documentation lenders and insurers actually want.
