(A) All damaged chimneys must be repaired or reconstructed to comply with the requirements of Chapter 37 of the Uniform Building Code. Damaged portions of chimneys shall be removed in accordance with the following criteria:
(1) 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 shall be braced to the roof structure using an approved method.
(2) Of 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 may be removed to the top of the firebox.
(3) For a multi-story structure, the damaged portion of the chimney shall be removed from the top to a floor line where anchorage is found.
(4) In any structure where the firebox has been damaged, the entire chimney and firebox shall 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 shall be removed and replaced.
(B) Where existing conditions preclude the installation of all anchorage required by Chapter 37 of the Uniform Building Code, alternate systems may be used in accordance with the alternate methods and materials provisions of the Uniform Building Code when approved by the Building Official.
(C) 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 shall be braced to the roof structure using an approved method.
