1 Final Action on 2018 International Building Code Group A Proposals Market Impact: H=High, M=Moderate, L=Low, N=None Position: O=Oppose, S=Support, MO=Mild Opposition, MS=Mild Support, N = None Action: A=Approve, D=Disapprove, =Approve as Modified, W=Withdrawn Designation Number Impact PCA Position Final Action Concept SECTION G GENERAL G 012 H O D Averages grade plane rather than lowest point 6 ft away G 024 H O 2 Specifically excludes occupied roofs from heights and areas G 099 H O W Allows Type III and V parking garages G 101 H S D Revises tier area of garages G 128 H S D Sprinkler trade offs in disaster prone areas G 131 H O D Roof occupancies not sprinklered. Need to watch and make sure where there is roof occupancy that exit passages accommodate additional occupant load. G 135 H S D Fire access roads for Type II, IV and V G 140 H S D Allowable areas in disaster prone areas. Taken from PCA change G 142 H S D Frontage increases G 144 H S D Frontage area increases G 152 H S D Fire resistance rating in disaster prone areas. Taken from PCA change Requires horizontal assembly to be Type I. Watch, may ultimately be G 161 H S 2 leading to remove 3 hr and just require Type I. Sort of redundant but does specifically require noncombustible. G 162 H S D Type V separated by 50 feet G 163 H O D Permits Type IV below horizontal assembly G 164 H S D Fire rating between dwelling units G 165 H O D Nine story Type IV. Prepping for CLT G 166 H S D Occupied roofs considered a story G 168 H O AS Removes fire resistance rating for Group R 3 Type IIB and Type VB where separation distance is more than 5 feet. G 169 H O D Reduces exterior bearing walls from 2 hr to 1 hr G 170 H O D Permits combustible Type III exterior loadbearing walls G 171 H S D Increased fire resistance rating for high risk areas G 172 H O D Permits combustible in Type III G 173 H O D Any fire retardant treated wood, not just framing G 174 H O D Any fire retardant treated wood, not just framing G 176 H S D Clarifies FRTW as non bearing G 177 H S D Requires inner and outer faces of ext walls to be non combustible. Fall back if 176 not approved. Don't let 176 move behind 177 G 178 H O AS Lumps CTL, solid and Glue Lam under heavy timber. G 179 H O AS Lumps CTL, solid and Glue Lam under heavy timber. I don't have any idea on arguments G 181 H O D Permits concealed spaces in Type IV where previously limited to without concealed spaces

2 G 182 H O D Generally lumps all associated wood products under CLT. No data seems to be presented to demonstrate comparable performance for all elements suggested. G 183 H O AS Reduces FRTW from 6 to 4 inches G 202 H S AS Enclosed elevator lobby G 207 H O AS Occupant evacuation elevators G 209 H O D Radon solid reinforced masonry Modify G 226 H S D Fire safety during construction G 228 H S D Access to 4 story Type V on all sides G 230 H S D Operational sprinklers before start of fourth floor G 232 H S D Fire watch for 40 foot Type V. Should be 30 foot. G 235 H O AS Design requirements for replicable buildings G 236 H S D Enhanced resiliency IBHS, FEMA SEI TMS ACI G 005 M MO D Adds combustible and noncombustible G 007 M MS D Adds student residence facilities to dormitories but required sleeping and cooking G 023 M S D Adds separation for roof decks used for assembly G 025 M MS D Make tenant space occupancy more stringent G 038 M MS D Adds student residence facilities to Group R 2 G 039 M MO D Adds condominiums (nontransient) to Group R 2 G 082 M O D Excludes R 1 multi family from extra stairway in high rises G 092 M O D Changes fire barrier to smoke barrier for atriums Could be okay if it were a smoke barrier with not less than a 1 hr fire resistance rating. G 097 M MS Allows private garages to be built to more stringent public garage 1 requirements. G 098 M O D Limits size of private garages G 100 M MO D Removes ramp access and leaves only mechanical access G 104 M O AS Adds public use and group meeting areas as similar areas to waiting areas that can be open to corridors. G 108 M MS W Reduces smoke compartment size. Smoke compartment could be formed with fire rated assemblies. Reduces smoke compartment size. Excludes radiology areas from G 109 M MS 1 reduction. Smoke compartment could be formed with fire rated assemblies. G 110 M MS D Reduces smoke compartment size. Smoke compartment could be formed with fire rated assemblies. G 117 M MS 1 Elevator protection G 118 M O AS Relaxes fire protection between sleeping units. Between sleeping units and baths is probably okay, but not between units G 132 M MS D Property lines for buildings on same property G 133 M MS Splits Group R into separate NFPA 13R and NFPA 13D heights and areas G 134 M MO D Excludes occupied roofs as a story G 158 M MO D Removes 10% area limit for incidental uses G 167 M O AS Removes fire protection for roof structural elements G 175 M MS AS Adds sheathing to requirement for wood framing to be FRTW

G 032 L S W Adds crisis center to Institutional Group I 1 G 033 L MO D Prohibits Group R 3 care facilities to comply with IRC but still permits NFPA 13D G 034 L MO D Removes NFPA 13D and simply references IRC which includes NFPA 13D for care of five or fewer G 040 L MS 1 Restricts lodging houses complying with IRC to owner occupied G 043 L O AS Removes area limits for accessory storage spaces. It appears obvious that larger spaces would then be treated as storage facilities. G 044 L S Adds self service storage to moderate hazard G 047 L MO AS Place communication equipment storage less than 1,500 sq ft in accessory. This could be a hazardous situation, batteries, etc. G 072 L MO D Relocates storm shelter criteria to G 078 L O D Permits exposed utility systems in exit passageways G 079 L MS D Open areas of high rise as assembly G 080 L S 1 Maintains fire protection Group H in IB buildings G 081 L MS AS Includes ancillary spaces for extra stairway in high rises G 083 L O AS Bases exit stairway on capacity in lieu of width G 089 L MS D Retains restrictions on atrium use G 091 L S D Removes smoke control for areas above atriums are separated G 114 L MS D Adds criteria for proscenium walls in Type I G 115 L MS 1 Increases stringency for air traffic control towers. G 119 L O Exempts fire partitions for Group R 3 and R 4. Could lead to further relaxations G 138 L O Mezzanine area. Poorly written, conditionally limits mezzanines to not more than 50% implying if more than 50% nothing needs to be done. G 147 L MO D Increases area of accessory spaces permitted to be sprinklered with 13R G 150 L MS D Requires more restrictions on un separated spaces G 151 L MS AS Requires more restrictive of separated spaces for sprinklers G 215 L MO D Permits combustible awnings on walkways. Should only be permitted where noncombustible exterior wall finishes Space heaters under awning and canopies. G 219 L S D Trellises of any material. Should be only combustible if exterior wall finishes are noncombustible. G 223 L MS 1 Relocatable buildings comply with code G 224 L MS W Public use restrooms in flood areas G 229 L MS AS Stairway required as construction progresses
