SOUTHERN NEVADA CODE AMENDMENT FORM – 2012AMENDMENT NO.:GC12-001COMMITTEE:GeneralCODE SECTION:Chapter 1PROPONENT:Jim Gerren, Clark CountyPROPOSAL:Delete Part 2 from Chapter 1 of the IBC.REVISE AS FOLLOWS:Delete Part 2 (“Administration and Enforcement”), including Sections 103 through 116 intheir entirety, from Chapter 1.JUSTIFICATION:Chapter 1 of the 2012 International Building Code (IBC) addresses “Scope andAdministration”. Part 1 of Chapter 1, which includes Sections 101 (General) and 102(Applicability) only, covers scope and application requirements. The provisions of Part 1are applicable to all Southern Nevada jurisdictions. However, Part 2 of Chapter 1addresses “Administration and Enforcement” and includes the following sections:Section 103 – Department of Building SafetySection 104 – Duties and Powers of Building OfficialSection 105 – PermitsSection 106 – Floor and Roof Design LoadsSection 107 – Submittal DocumentsSection 108 – Temporary Structures and UsesSection 109 – FeesSection 110 – InspectionsSection 111 – Certificate of OccupancySection 112 – Service UtilitiesSection 113 – Board of AppealsSection 114 – ViolationsSection 115 – Stop Work OrderSection 116 – Unsafe Structures and EquipmentEach jurisdiction in Southern Nevada typically addresses administration andenforcement requirements, such as those topics addressed by IBC Sections 103 through116, through their own local ordinances (i.e., local Building Administrative Codes).Therefore, this proposal recommends that Part 2 of Chapter 1 be deleted in its entiretyso as to eliminate potential inconsistencies and conflicts between Part 2 of IBC Chapter1 and the local ordinances that cover administration and enforcement requirements.Southern Nevada General CommitteePage 5 of 167

There may be some concern with leaving Section 101.4 (“Referenced codes”) in Chapter1 since it addresses several codes that may not be adopted by all of the SouthernNevada jurisdictions. However, this potential issue can be resolved with ProposalGC12-003, which defines all of the various International Codes as “the code as adoptedand amended by the local jurisdiction”.COST IMPACT:This amendment will not affect the cost of construction.COMMITTEE ACTION: Motion to approve and trictJBRBJGAPAPAPAPAPIndustryRESULT: Approved.STEERING COMMITTEE RECOMMENDATION: Concurs.Southern Nevada General CommitteePage 6 of 167

SOUTHERN NEVADA CODE AMENDMENT FORM – 2012AMENDMENT NO.:GC12-002COMMITTEE:GeneralCODE SECTION:Section 202PROPONENT:Jim Gerren, Clark CountyPROPOSAL:Revise the definition of “High-Rise Building” in Section 202.REVISE AS FOLLOWS:HIGH-RISE BUILDING. A building with an occupied floor located more than 55 feet(16 764 mm) 75 feet (22 860 mm) above the lowest level of fire department vehicleaccess.JUSTIFICATION:In accordance with NAC 477.283.2(b), the Nevada State Fire Marshal requires the highrise building provisions of Section 403 to apply to all buildings having occupied floorslocated more than 55 feet above the lowest level of fire department vehicle access. Theproposed amendment revises the definition of “high-rise building” for consistency withNAC 477.283.2(b). The proposed amendment is consistent with Nevada RevisedStatutes and past Southern Nevada building code amendments.COST IMPACT:This will increase the cost of construction; no impact relative to previous Southern NVamendments.COMMITTEE ACTION: Motion to approve and rictJBRBJGAPAPAPAPAPIndustryRESULT: ApprovedSTEERING COMMITTEE RECOMMENDATION: Concurs.Southern Nevada General CommitteePage 7 of 167

JUSTIFICATION:The IBC contains numerous references to the above-listed International Codes.However, such references to these International Codes in the IBC create potentialconflicts with the codes actually adopted by Southern Nevada jurisdictions because (a)the jurisdictions may not adopt the same editions of these codes, and (b) thejurisdictions may adopt codes other than those published by the ICC (e.g., the UniformPlumbing Code and Uniform Mechanical Code as published by IAPMO). The proposeddefinitions would direct the user to the applicable adopted code without requiringchanges to be made throughout the IBC. This approach is consistent with the methodused to address this issue in the adopted and amended 2000, 2006, and 2009 editionsof the IBC. All of the codes identified in this amendment are referenced within the 2012IBC, as noted in IBC Chapter 35.COST IMPACT: None.COMMITTEE ACTION: Motion to approve and trictJBRBJGAPAPAPAPAPIndustryRESULT: ApprovedSTEERING COMMITTEE RECOMMENDATION: Concurs.Southern Nevada General CommitteePage 9 of 167
