Chimney fire clearance distances between masonry & wood framing: This article describes the fire clearances required for masonry chimneys. The distance between a brick, stone, concrete block,or other masonry chimney and the nearest combustible material, such as wood framing, is an important fire safety consideration that must be respected.

As Carson Dunlop's sketches (above) illustrate, proper masonry construction leaves space between wood framing members and the chimney, or where framing rests on or in a masonry chimney, at least 12" of solid masonry should separate the chimney flue from the nearest wood framing member.
Readers of this article should also see CHIMNEY HEIGHT & CLEARANCE CODE. This article series on chimneys, chimney construction, and chimney safety provide detailed suggestions describing how to perform a thorough visual inspection of chimneys for safety and other defects.
Inspectors of older homes often find wood framing built right against masonry chimneys and at times we find wood framing that rests in a pocket in a masonry chimney structure, using the chimney to support the building framing.
