Chimney Height Violations: The 3’:2’:10’ Rule

For Safety purposes, building code requires that a chimney must meet the 3:2:10 requirement. The 3:2:10 requirement states that the chimney must terminate at least 3 feet above the highest point of the roof that it penetrates, and be at least 2 feet higher than anything within an imaginary 10’ horizontal radius encompassing the top of the chimney.

Changed Roof Pitch with Masonry Chimney - Sacramento CA - A to Z Chimney Services

When these homeowners changed the pitch of their roof, they neglected to raise the height of the chimney. This chimney termination does not extend at least 3′ above the roof as required.

This requirement is primarily for two reasons:

1. To ensure nearby combustible objects are less likely to catch fire. Objects such as trees, roofs gables, walls, etc. must all be kept at a respectable distance to prevent an unintentional fire.

2. To keep your fireplace from smoking into your home by trying to ensure the chimney will draft properly. If the top of your chimney is too close to an adjacent object such as a tree, wall, or nearby building, wind may create a high pressure plane that may push air down your chimney and force smoke into your home. In some situations, even though your chimney meets minimum height requirements, it may still need to be extended higher in order to draft properly.
