   R110.2.6 Modifications. Wherever there are practical difficulties involved in carrying out the provisions of this code, the code official shall have the authority to grant modifications for individual cases, upon application of the owner or owner's representative, provided the code official shall first find that special individual reason makes the strict letter of this code impractical and the modification is in compliance with the intent and purpose of this code and that such modification does not lessen health, accessibility, life and fire safety, or structural requirements.

   R110.2.8 Research reports. Supporting data, where necessary to assist in the approval of materials or assemblies not specifically provided for in this code, shall consist of valid research reports from approved sources.
   R110.2.9 Tests.

   Mandatory testing shall only be performed by individuals that are certified to perform air infiltration testing by national or state organizations as approved by the building official. The certified individuals must be an independent third-party entity, and may not be employed by; or have any financial interest in the company that constructs the structure.
      Exception: One- and two-family dwellings less than 6000 square feet (557 m2) with not less than 2 nor more than 6 bedrooms are permitted an air leakage rate not exceeding four air changes per hour when complying with table 402.4.1.2.

IECC SECTION R501
GENERAL
   *IECC Section R501.6; changed to read as follows:
   R501.6 Historic buildings. No provision of this chapter relating to the construction, repair, alteration, restoration and movement of structures, and change of occupancy shall be mandatory for historic buildings provided a report has been approved by the code official and signed by the owner, a registered design professional, or a representative of the State Historic Preservation Office, or the historic preservation authority having jurisdiction, demonstrating that compliance with that provision would threaten, degrade, or destroy the historic form, fabric, or function of the building.
IECC SECTION R503
ALTERATIONS
   *IECC Section R503.1; add a final paragraph to read as follows:
   Compliance methods permitted by this code or former codes may include a variety of above code options. Such above code options may have been used to allow another design parameter to be reduced. In order to insure that such above code upgrades are not later remodeled away, unless it can be shown that the total building after remodel complies with code, all replacement material, equipment and/or systems shall meet the most restrictive requirement of:
   1.   having an equivalent reduction of energy usage as the replaced material, equipment and/or system; or,
   2.   comply with the prescriptive provisions of this code.
   *IECC Section R503.1.1.2; added to read as follows:
   R503.1.1.2 Roof insulation above deck.  (life safety) When the insulation is on top of the roof deck and the insulation is removed, repaired or replaced, new insulation is required to be installed. If the new insulation is to be installed on top of the roof deck, the new insulation shall attempt to meet the R-value as required by this code unless doing so endangers the building by interfering with the roof drainage system. If compliance with this code does so endanger the building, at a minimum the insulation R-value shall be not less than what was removed.
