Question on construction



I have seen a few posts on chimneys recently in this group.



What is the general rule on chimneys in terms of height ?



How much higher than the roof do they have to be ? Can they be in line with the roof ?



Is there a law on this ? especially in N. California ?



Thanks Jessica

chimney must be 3ft above roof line |

The "law" is the Mechanical section of the Building Code.

Dean's link gives good info on the heights.

You might want to check with your local building permit department has I think CA has a requirement for spark arrestors and may have other local requirements.

Steve.

General guidelines state that the chimney must be at least 2 feet above any portion of the roof that is within 10 feet of the chimney. With a steep roof this can make for a really tall chimney. Shallow roofs can make for squatty ones.

Your local regulations may be different.

I don't know CA rules, but I was told the 3,2,10 rule seems general enough.

Chimney must be 3 feet high, and 2 feet higher than anything within 10 feet.

Don't hold me to this, since it was give as a quick tip, and I don't live in CA.
