Can I always just get a Level 2 to be safe?

You can, but it costs more than needed for a routine annual check on an unmodified, undamaged system.

Does adding gas logs require a Level 2?

Yes, any system change calls for a Level 2 rather than a routine Level 1.

Chimney Inspection Levels Explained

Q: How often should I get a Level 1 inspection?

Annually, alongside your regular sweep, for normal unmodified use with no red flags.

Level 1, 2, or 3: which chimney inspection do you actually need

The three inspection levels aren’t a menu of good, better, best. Each one is defined for a specific situation by the same national fire code, NFPA 211, and using the wrong one either wastes money or misses real problems.

NFPA 211 is the national fire code that defines these three inspection levels, and it ties each one to a specific trigger, not to how much you want to spend. Here’s what each one actually involves.

The three levels

Level 1

A visual check of all readily accessible parts of the chimney, appropriate for an annually used, unmodified system with no known problems.

Level 2

Adds a full camera scope of the flue interior. Required for real estate transactions, after any chimney fire, after a system change like a new appliance, or after severe weather damage.

Level 3

Adds removal of parts of the chimney or adjacent structure to access a suspected hidden hazard identified during a Level 2. Rare, and only used when Level 2 findings point to something Level 2 can’t fully assess.

A home sale almost always calls for a Level 2, not a Level 1. If you’re buying or selling and someone offers a quick Level 1 as sufficient, that’s not meeting the standard a real estate transaction calls for.

Which one applies to you

Annual check, same system, no known issues: Level 1

Buying, selling, or refinancing a home with a fireplace: Level 2

Had a chimney fire, even a small one: Level 2, minimum

Level 2 found something it couldn’t fully explain: Level 3
