2. The addition does not increase the seismic forces in any structural element of the existing structure by more than 10 percent cumulative since the original construction, unless the element has the capacity to resist the increased forces determined in accordance with generally accepted engineering practices such as ASCE 7, using professional structural engineering computer software, and
3. Addition does not decrease the seismic resistance of any structural element of the existing structure by more than 10 percent cumulative since the original construction, unless the element has the capacity to resist the forces determined in accordance with generally accepted engineering practices such as ASCE 7, using professional structural engineering computer software.

Alterations that increase the seismic force in any existing structural element by more than 10 percent cumulative since the original construction or decrease the design strength of any existing structural element to resist seismic forces by more than five percent cumulative since the original construction shall not be permitted unless the entire seismic-force-resisting system is determined to conform generally accepted engineering practices such as ASCE 7, using professional structural engineering computer software for a new structure. If the building's seismic base shear capacity has been increased since the original construction, the percent change in base shear may be calculated relative to the increased value.
Exception: Alterations to existing structural elements or additions of new structural elements that are not required by generally accepted engineering practices such as ASCE 7, using professional structural engineering computer software and are initiated for the purpose of increasing the strength or stiffness of the seismic-force-resisting system of an existing structure need not be designed for forces conforming to generally accepted engineering practices such as ASCE 7, using professional structural engineering computer software, provided that an engineering analysis is submitted indicating the following:
1. The design strength of existing structural elements required to resist seismic forces is not reduced.
2. The seismic force to required existing structural elements is not increased beyond their design strength.
3. New structural elements are detailed and connected to the existing structural elements as required by Chapter 16.
4. New or relocated nonstructural elements are detailed and connected to existing or new structural elements as required by Chapter 16.
5. The alterations do not create a structural irregularity as defined by generally accepted engineering practices such as ASCE 7, using professional structural engineering computer software or make an existing structural irregularity more severe.
6. The alterations do not result in the creation of an unsafe condition.
(y) Add a new subsection 1613.5.3 to read as follows: 1613.5.3 Change of occupancy. When a change of occupancy results in a structure being reclassified to a higher occupancy category, the structure shall conform to the seismic requirements for the higher occupancy category.
(Fire Prevention and Building Safety Commission;
Exceptions: 1. Specific seismic detailing requirements of this code for a new structure shall not be required to be met where it can be shown by generally accepted engineering practices such as ASCE 7, using professional structural engineering computer software that the level of performance and seismic safety is equivalent to that of a new structure. Such analysis shall consider the regularity, overstrength, redundancy, and ductility of the structure within the context of the existing and retrofit (if any) detailing provided.
2. When a change of use results in a structure being reclassified from Risk Category I or II to Risk Category III and the structure is located in a seismic map area where SDS < 0.33, compliance with the seismic requirements of this code are not required.
