What Is a Level 2 Chimney Inspection?

A Level 2 chimney inspection is the mid-depth inspection defined by NFPA 211, the national standard for chimneys and venting systems. It includes everything in a basic Level 1 visual check — all readily accessible parts of the chimney, inside and out — and adds a video camera scan of the complete interior of every flue, plus examination of accessible attics, crawl spaces, and basements where the chimney passes through, and verification of clearances to combustible materials. If you've been told you need "a camera inspection" or "a real estate chimney inspection," a Level 2 is what's being described.

The NFPA 211 Definition

NFPA 211 (the Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances) defines three inspection levels. Level 1 is a visual examination of readily accessible portions of the chimney and appliance, appropriate for routine annual checks on an unchanged system. Level 3 involves removing building components — opening walls, dismantling parts of the chimney — and is reserved for investigating known serious hazards.

Level 2 sits between them: everything in Level 1, plus a video scan or other internal imaging of the flue, plus inspection of accessible portions of the building the chimney passes through (attic, crawl space, basement), plus verification that proper clearances to combustibles are maintained. It is non-destructive — nothing is opened up or removed — but it examines every part of the system that can be reached without demolition. The output is typically a written report with camera images documenting the condition of each flue.

When a Level 2 Is Required

NFPA 211 names specific triggers that call for a Level 2 inspection rather than a Level 1:

• Sale or transfer of the property. Every real estate transaction involving a chimney is a Level 2 event under the standard, because the new owner has no operating history with the system. This is the most common trigger — and the reason Rochester's home-sale inspection norms treat a camera inspection as expected practice on the city's older housing.
• Any change to the system. Installing a new appliance, switching fuels (for example, a furnace replacement or a conversion to gas), changing flue size or type, or relining all require Level 2 before the system goes back into service.
• After an operating malfunction or external event. A chimney fire, a lightning strike, or a building or weather event likely to have caused damage all trigger Level 2 — even if the chimney "seems fine" afterward.

In practical terms: if you bought your Rochester home without one, changed a furnace, or had a chimney fire at any point, the standard says a Level 2 inspection is due. On the city's century-old housing stock — Corn Hill, the 19th Ward, Park Avenue — that describes a large share of chimneys.

What the Camera Scan Covers

The camera is the defining feature of Level 2. The technician feeds a video camera up (or down) the complete length of every flue in the stack, examining each clay tile joint, liner section, and offset along the way. What it routinely finds on older Rochester chimneys:

• Cracked, shifted, or missing flue tiles — accelerated locally by a century of freeze-thaw cycling.
• Open joints between liner sections, which let heat and combustion gases reach surrounding masonry and framing.
• Evidence of past chimney fires — heat-fractured tiles, puffed creosote residue — that the current owner may never have known about.
• Abandoned stovepipe openings and past alterations, common in homes that went through apartment conversions or fuel switches.
• Unlined flues serving modern gas appliances, whose corrosive condensate eats masonry from the inside.

Multi-flue stacks — one flue for the fireplace, one for the furnace, sometimes a third abandoned run — are the norm on Rochester's older homes, and each flue gets its own camera pass. If the flue is too dirty to film, a sweeping is performed first so the camera can actually see the liner surface.

Typical Cost in Rochester

As a ballpark for the Rochester area: a Level 2 inspection with camera and written report typically costs $200–$500, depending on the number of flues, chimney height, and accessibility. If sweeping is needed before the camera run, that may add $150–$300. The inspection usually takes one to two hours on site, and the written report with images typically arrives the same day or within 24 hours.

Two things to confirm when getting quotes: that the price covers every flue in the stack, and that the deliverable includes a written report with camera images or video — that documentation is what makes the inspection useful for a home purchase negotiation, an insurance file, or your own maintenance records.
