All damaged chimneys must be repaired or reconstructed to comply
with the requirements of Chapter 21 of the California Building Code.
Damaged portions of chimneys must be removed in accordance with the
following criteria.
(Ord. 1593 § 2, 2022)
When the damaged portion of the chimney is located between the
roof line and the top of the chimney, the damaged portion may be removed
to the roof line provided the roof and ceiling anchorage are in sound
condition. The reconstruction portion of the chimney must be braced
to the roof structure using an approved method.
(Ord. 1593 § 2, 2022)
For a single-story structure in which the damaged portion of
the chimney is below the roof line, or the damaged portion extends
from above the roof line to below the roof line, the chimney must
be removed to the top of the firebox.
(Ord. 1593 § 2, 2022)
For a multi-story structure, the damaged portion of the chimney
must be removed from the top to a floor line where anchorage is found.
(Ord. 1593 § 2, 2022)
In any structure where the firebox has been damaged, the entire
chimney and firebox must be removed to the foundation. If the foundation
is in sound condition, the firebox and chimney may be reconstructed
using the existing foundation. If the foundation has been damaged,
the foundation must be removed and replaced. Such reconstruction and
replacement must be in accordance with Chapter 21 of the California
Building Code.
(Ord. 1593 § 2, 2022)
Where existing conditions preclude the installation of all anchorage
required by Chapter 21 of the California Building Code, alternate
systems may be used in accordance with the alternate methods and materials
provisions of the California Building Code when approved by the building
official.
(Ord. 1593 § 2, 2022)
Where the portion of the chimney extending above the roof line
exceeds two times the least dimension of the chimney, that portion
above the roof line must be braced to the roof structure using an
approved method.
(Ord. 1593 § 2, 2022)
