  •   Chapter 11 of the IFC® 2015 is adopted with the following modifications:
    (1)   Section 1101.1 Scope. This section has been modified to include an exception allowing for structures complying with the International Existing Building Code®(IEBC®) be considered safe enough to where the provisions of Chapter 11 would not apply and resolve discrepancies between the two codes. This section has been modified to read: 1101.1 Scope. The provisions of this chapter shall apply to existing buildings constructed prior to the adoption of this code. Exception: Buildings or portions of a building that comply with the latest edition of the IEBC® or the edition that was adopted at the time a remodel occurred.
    (2)   Section 1103.4.2 Three to five stories. This section has been modified to add a fifth exception to provide relief from this section of the code when vertical openings comply with the requirements of Section 803.2.1 of the IEBC®. This section has been modified to read: 1103.4.2 Three to five stories. In other than Group I-2 and I-3 occupancies, interior vertical openings connecting three to five stories shall be protected by either 1-hour fire-resistant-rated construction or an automatic sprinkler system shall be installed throughout the building in accordance with Section 903.3.1.1 or 903.3.1.2. Exceptions:

    (D)   Exit access stairways and ramps shall be in accordance with Section 1103.4.8.
    (E)   Vertical openings that comply with the requirements of Section 803.2.1 of the IEBC®.
    (3)   Section 1104.1 General. This section has been modified to allow the means of egress in an existing building to be considered as complying if in the opinion of both the building code official and the fire code official they do not constitute a distinct hazard to life. This section has been modified to read: 1 1104.1 General. Means of egress in existing buildings shall comply with the minimum egress requirements when specified in Table 1103.1 as further enumerated in Section 1104.2 through 1104.25 or the building code that applied at the time of construction, if, in the opinions of the building official and the fire code official, they do not constitute a distinct hazard to life. Existing buildings that were not required to comply with a building code at the time of construction shall comply with the minimum egress requirements when specified in Table 1103.1 as further enumerated in Sections 1104.2 through 1104.25.
    (4)   Section 1104.18 Dead ends. This section has been modified to add another exception to the requirements of this section provided the dead ends comply with the requirements of Section 705.6 of the International Existing Building Code®. This section has been modified to read: 1104.18 Dead ends. Where more than one exit or exit access doorway is required, the exit access shall be arranged such that dead ends do not exceed the limits specified in Table 1104.18. In Group I-2, in smoke compartments containing patient sleeping rooms and treatment rooms, dead end corridors shall be in accordance with Section 1105.5.6. Exceptions:
    (A)   A dead-end passageway or corridor shall not be limited in length where the length of the dead-end passageway or corridor is less than 2.5 time the least width of the dead-end passageway or corridor.
    (B)   Dead ends that comply with the requirements of Section 805.6 of the IEBC®.
    (5)   Section 1104.25 Egress path markings. This section, including the exception, has been moved and renumbered into the newly created Appendix N, entitled "Egress Path Markings for Existing Buildings" and is not adopted as a minimum standard for residential or commercial fire prevention and fire protection systems within the State of Oklahoma. The section number 1104.25 itself, will stay as part of this code for numbering alignment but will not have any requirements attached to it.
