The provisions of Section 1201 of IEBC are adopted by reference with the following modifications:
1. Revise Section 1201.1 by replacing "shall" with "may elect to."
1.1. Revise Section 1201.2 to read:
"1201.2 Report.
A historic building undergoing alteration or change of occupancy shall be investigated and evaluated. If it is intended that the building meet the requirements of this chapter, a written report shall be prepared and filed with the building official by a registered design professional. Such report shall identify each required safety feature that is in compliance with this chapter and where compliance with other chapters of these provisions would be damaging to the contributing historic features. For buildings assigned to Seismic Design Category D, a structural evaluation describing, at a minimum, the vertical and horizontal elements of the lateral force-resisting system and any strengths or weaknesses therein shall be prepared. Additionally, the report shall describe each feature that is not in compliance with these provisions and shall demonstrate how the intent of these provisions is complied with in providing an equivalent level of safety.
Exception: Where the building official determines that the construction documents are sufficient to identify features not otherwise in compliance with other chapters of this code, the building official may waive the report requirement."
2. Revise Section 1201.3 to read:
"1201.3 Special occupancy exceptions-museums.
Where a historic building originally intended for Group R-3 or R-5 occupancy is used for Group A, B or M purposes such as museum tours, exhibits, and other public assembly activities, or for museums or galleries less than 5,000 square feet (465 m2), the building official may determine that the occupancy is Group B where life safety conditions can be demonstrated in accordance with Section 1201.2. Adequate means of egress in such buildings, which may include a means of maintaining doors in an open position to allow egress, a limit on building occupancy to an occupant load allowed by the means of egress capacity, a limit on occupancy of certain areas or floors, or supervision by a person knowledgeable in the emergency exiting procedures, shall be approved by the building official."
3. Delete Section 1201.4.
