1061 (1) In IRC, Section R102, a new Section R102.7.2 is added as follows: "R102.7.2
1062 Physical change for bedroom window egress in legal nonconforming rental housing use. A
1063 structure classified as a legal nonconforming rental housing use, whose egress bedroom
1064 window is smaller than required by this code, is not required to undergo a physical change to
1065 conform to this code if the change would compromise the structural integrity of the building or
1066 could not be completed in accordance with other applicable requirements of this code,
1067 including setback and window well requirements."
1068 (2) In IRC, Section 109:
1069 (a) A new IRC, Section 109.1.5, is added as follows: "R109.1.5 Weather-resistant
1070 exterior wall envelope inspections. An inspection shall be made of the weather-resistant

1071 exterior wall envelope as required by Section R703.1 and flashings as required by Section
1072 R703.8 to prevent water from entering the weather-resistive barrier."
1073 (b) The remaining sections are renumbered as follows: R109.1.6 Other inspections;
1074 R109.1.6.1 Fire- and smoke-resistance-rated construction inspection; R109.1.6.2 Reinforced
1075 masonry, insulating concrete form (ICF) and conventionally formed concrete wall inspection;
1076 and R109.1.7 Final inspection.
1077 (3) IRC, Section R114.1, is deleted and replaced with the following: "R114.1 Notice to
1078 owner. Upon notice from the building official that work on any building or structure is being
1079 prosecuted contrary to the provisions of this code or other pertinent laws or ordinances or in an
1080 unsafe and dangerous manner, such work shall be immediately stopped. The stop work order
1081 shall be in writing and shall be given to the owner of the property involved, or to the owner's
1082 agent or to the person doing the work; and shall state the conditions under which work will be
1083 permitted to resume."
1084 (4) In IRC, Section R202, the following definition is added: "CERTIFIED
1085 BACKFLOW PREVENTER ASSEMBLY TESTER: A person who has shown competence to
1086 test Backflow prevention assemblies to the satisfaction of the authority having jurisdiction
1087 under Utah Code, Subsection 19-4-104 (4)."
1088 (5) In IRC, Section R202, the definition for "CONDITIONED SPACE" is modified by
1089 deleting the words at the end of the sentence "being heated or cooled by any equipment or
1090 appliance" and replacing them with the following: "enclosed within the building thermal
1091 envelope that is directly heated or cooled, or indirectly heated or cooled by any of the following
1092 means:
1093 1. Openings directly into an adjacent conditioned space.
1094 2. An un-insulated floor, ceiling or wall adjacent to a conditioned space.
1095 3. Un-insulated duct, piping or other heat or cooling source within the space."
1096 [(5)] (6) In IRC, Section R202, the definition of "Cross Connection" is deleted and
1097 replaced with the following: "CROSS CONNECTION. Any physical connection or potential
1098 connection or arrangement between two otherwise separate piping systems, one of which
1099 contains potable water and the other either water of unknown or questionable safety or steam,
1100 gas, or chemical, whereby there exists the possibility for flow from one system to the other,
1101 with the direction of flow depending on the pressure differential between the two systems (see

1102 "Backflow, Water Distribution")."
1103 (7) In IRC, Section 202, in the definition for gray water a comma is inserted after the
1104 word "washers"; the word "and" is deleted; and the following is added to the end: "and clear
1105 water wastes which have a pH of 6.0 to 9.0; are non-flammable; non-combustible; without
1106 objectionable odors; non-highly pigmented; and will not interfere with the operation of the
1107 sewer treatment facility."
1108 [(6)] (8) In IRC, Section R202, the definition of "Potable Water" is deleted and
1109 replaced with the following: "POTABLE WATER. Water free from impurities present in
1110 amounts sufficient to cause disease or harmful physiological effects and conforming to the
