KEY CHANGES TO THE 2012 I-CODES

AT THE ANNUAL ICC Conference and Final Action Hearing in October 2010 in Charlotte, NC the following changes were approved and will appear in the 2012 International Codes.

KEY CHANGES TO THE 2012 I-CODES 2012 International Building Code

KEY CHANGES TO THE 2012 I-CODES-IBC

Administration

102.4 - Supplemental language has been added to address potential conflicts to clarity that the IBC provisions govern over referenced standards. 104.10.1 â&#x20AC;&#x201C; New section added to transfer provisions for granting modifications in flood hazard areas previously in Appendix G105 to the body of the code and revising that sectionâ&#x20AC;&#x2122;s limitation that changes must be approved by the board of appeals. Now the building official has the authority to grant modifications.

KEY CHANGES TO THE 2012 I-CODES-IBC

Definitions

 Definitions have been moved from other locations in the code to Chapter 2.

 Defined terms are still listed in their respective chapters but reference back to Chapter 2

 All defined terms are italicized throughout the code to remind users there is a definition for them.

KEY CHANGES TO THE 2012 I-CODES-IBC

Occupancy Clarifications

 303.1.3 - A room or space used for assembly purposes in Group E

not considered a separate occupancy. Chapter 11 accessibility and Chapter 10 egress requirements for assembly occupancies still apply, but the mixed occupancy provisions of Chapter 5 do not.

 303.4 – Casino floor occupancy classification now clearly A-2, food and drink consumption, due to same characteristics of distracting light, sound, unclear egress paths, and usually drink consumption.

 303.3, 306.2 - Commercial kitchens serving large restaurants now

considered A-2 occupancies. Only kitchens with no associated dining area are considered F-1, such as catering uses. Separation requirement has been eliminated from Table 508.4.

KEY CHANGES TO THE 2012 I-CODES - IBC

Care Definitions and Requirements Revised Comprehensive revisions were made in Chapter 3 to define and clarify medical care, custodial care and personal care.

Medical care is primarily I-2, where 6 or more people incapable of self preservation are receiving care. Where they do not exceed five, may be Group R-3 or regulated by IRC.

Custodial care is primarily I-1 (17 or more occupants) and personal care is R-4 (6 – 16 occupants. All are capable of self preservation. Both care definitions are similar and do not include medical care.

KEY CHANGES TO THE 2012 I-CODES-IBC

Chapter 4 Special Occupancies 402 – Open Mall Buildings, first defined in the 2009 IBC, and

becoming increasingly popular, now given a variety of changes including the new concept of a open mall building perimeter line that defines what is within the mall. This section was reorganized along topics with all egress in 402.8 and all construction in 402.3.

407 – Regulations that were in Chapter 10 regarding patient care suites proliferating in hospitals now revised and relocated to 407.

KEY CHANGES TO THE 2012 I-CODES-IBC

 410 – Fly galleries, gridirons and pinrail terms have been

consolidated under a new definition, technical production area. Most of the Chapter 10 exit requirements except for reference to Table 1015.1 have been relocate to this section. Some smaller stages are now allowed to have only one exit.

 424 – Children’s play areas, formerly only applicable to covered

mall buildings, now have their own section and are regulated regardless of the building in which they are located. Use of NFPA 289 as an alternative to UL 1975 is allowed for testing of foam plastics and ball pool balls that are commonly used in play structures.

KEY CHANGES TO THE 2012 I-CODES-IBC

Chapter 5 Heights and Areas  501.2 – The Fire Official is now allowed to require additional

locations for building ID and the numbers must be maintained.

 505.2.2 – Mezzanine egress is now required per Chapter 10 with no special provisions allowed.

KEY CHANGES TO THE 2012 I-CODES-IBC

Chapter 5 – Building Heights and Areas  506.2 - Has been clarified for three issues, the amount of public

way to be used, the method for measuring available width and defining “weighted average”. This eliminated some of the confusion caused by Section 702.1 for fire separation distance, which only allows use of the public way to the centerline.

 Revisions to 507 - clarify measurement of the open area around unlimited area buildings and accessory uses in unlimited area buildings.

KEY CHANGES TO THE 2012 I-CODES-IBC

Fire Protection Chapters-7 to 9 412 and 413 - Shaft enclosure provisions

have been relocated and reorganized and revised under two sections to emphasize vertical openings since shaft enclosure is just one method mitigate the hazards related to vertical openings.

706.2 – Fire walls are now allowed to use

the provisions of NFPA 221 for a double fire wall to provide the complete burnout on one side that has always been required. New provisions require increased parapet heights for fire walls adjacent to sloped roofs. Copyright 2011 - Kelly P. Reynolds & Associates, Inc. - All Rights Reserved

KEY CHANGES TO THE 2012 I-CODES-IBC Chapter 10 Means of egress 1001.4 – new reference to the IFC fire safety and evacuation plans Section 401.2 and 404. To provide consistency and to “adopt by reference” even though the IFC may not be adopted. 1004.1.2, Table 1004.1.2 – A new classification for areas without fixed seating specifically for exhibitions and museums of 30 square foot per person.

Entire section reorganized and previous section 1004.4 has been incorporated as last sentence of 1005.3.1.

KEY CHANGES TO THE 2012 I-CODES-IBC

1008.1.9.9 – Electromagnetically locked egress doors now allowed with integral panic bars because they have been tested and listed, not previously available at 2009 IBC issuance. Note this specific allowance overrides the general prohibition in 1008.1.10 that doors requiring panic hardware “shall not be provided with a latch or lock unless it is panic hardware or fire exit hardware”.

KEY CHANGES TO THE 2012 I-CODES-IBC

1011.2 â&#x20AC;&#x201C; Low level exit signs for Group R-1 occupancies are back. A provision in the Uniform Building Code since the 1991 edition, this requirement was based on numerous hotel loss of life fires, including the MGM Grand fire in Las Vegas in 1980 where the corridor system becomes obscured by smoke. These are also thought to be useful for firefighters to gain egress from the fire floor. They have never been in the I-Codes until now.

KEY CHANGES TO THE 2012 I-CODES-IBC

Chapter 10 – Means of Egress – Handrails and guards 1012.2 - Transition pieces of continuous handrails are now permitted to exceed maximum prescriptive height. 1012.3.1 and 1012.8 – Minimum cross section dimension now provided for noncircular handrails. 1013.1 and 1013.8 - Guard requirements for operable windows located more than 72 inches above grade are relocated from Chapter 14 and the minimum window sill height for which a guard is not required has gone from 24 to 36 inches. 1013.3 – Guard height has been reduced from 42 inches to 36 inches in Group R-2 and R-3 Occupancies less than three stories to coordinate with IRC provisions.

KEY CHANGES TO THE 2012 I-CODES-IBC 1021.2 – Exits from stories – not all exits have to be accessible to all occupants if there are sufficient exits (not less than 2) accessible to all. 1021.2.1 and Table 1021.2(2) – A new ratio equation is used to determine if a single exit can serve different occupancies.
