C.

Section 104.4.1 is amended by the addition of the following wording:

 104.4.1 Reinspections. A reinspection fee may be assessed for each inspection or reinspection when such portion of the work for which inspection is called is not complete or when corrections called for are not made.

 This section is not to be interpreted as requiring reinspection fees the first time a job is rejected for failure to comply with the requirements of this code, but as controlling the practice of calling for inspections before the job is ready for such inspection or reinspection.

 Reinspection fees may be assessed when the inspection record card is not posted or otherwise available on the work site, the approved plans are not readily available to the inspector, for failure to provide access on the date for which inspection is requested, or for deviating from plans requiring the approval of the chief building official.

 To obtain a reinspection, the applicant shall file an application therefore in writing on a form furnished for that purpose and pay the reinspection fee in accordance with Section 15.08.030.

 In instances where reinspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid.

D.

Section 104.2 fees shall be as indicated in Section 15.08.030 of the Cheyenne City Code.

Section R402.4.1.2 is amended to read as follows:

 R402.4.1.2 Testing. The building or dwelling unit shall be tested and verified as having an air leakage rate of not exceeding 5 air changes per hour in Climate Zones 1 and 2, and 4 air changes per hour in Climate Zones 3 through 8. Testing shall be conducted with a blower door at a pressure of 0.2 inches W.G. (50 pascals). Where required by the code official, testing shall be conducted by an approved third party. A written report of the results of the test shall be signed by the party conducting the test and provided to the code official. Testing shall be performed at any time after creation of all penetrations of the building thermal envelope.

The remainder of Section 402.4.1.2 is unchanged.

Table R402.1.2 is amended to read as follows:

 1. Table R402.1.2

Insulation and Fenestration Requirements by Component ^a

Climate Zone	Fenes- tration U-Factor b	Skylight b U-Factor	Glazed Fenes- tration SHGC b	Ceiling R-Value	Wood- frame Wall R-Value	Mass Wall R-Value g	Floor R-Value	Basement c Wall R-Value	Slab d R-Value & Depth	Crawl- space c Wall R-Value
6	0.35	0.60	NR	49	20 or 13+5 f	15/19	30 e	15/19	10, 4 ft	10/13

 

  ^a. R-values are minimums. U-factors and SHGC are maximums. R-19 batts compressed into a nominal 2 × 6 framing cavity such that the R-value is reduced by R-1 or more shall be marked with the compressed batt R-value in addition to the full thickness R-value.

  ^b. The fenestration U-factor column excludes skylights. The SHGC column applies to all glazed fenestration.

  ^c. "15/19" means R-15 continuous insulated sheathing on the interior or exterior of the home or R-19 cavity insulation at the interior of the basement wall. "15/19" shall be permitted to be met with R-13 cavity insulation on the interior of the basement wall plus R-5 continuous insulated sheathing on the interior or exterior of the home. "10/13" means R-10 continuous insulated sheathing on the interior or exterior of the home or R-13 cavity insulation at the interior of the basement wall.

  ^d. R-5 shall be added to the required slab edge R-values for heated slabs. Insulation depth shall be the depth of the footing or 2 feet, whichever is less in Zones 1 through 3 for heated slabs.

  ^e. Or insulation sufficient to fill the framing cavity, R-19 minimum.

  ^f." 13+5" means R-13 cavity insulation plus R-5 insulated sheathing. If structural sheathing covers 25 percent or less of the exterior, insulating sheathing is not required where structural sheathing is used. If structural sheathing covers more than 25 percent of exterior, structural sheathing shall be supplemented with insulated sheathing of at least R-2.

  ^g. The second R-value applies when more than half the insulation is on the interior of the mass wall.

K.

Table R402.1.4 is amended to read as follows:

Table R402.1.4
Equivalent U-Factors ^a

  ^a. Nonfenestration U-factors shall be obtained from measurement, calculation or an approved source.

  ^b. When more than half the insulation is on the interior, the mass wall U-factors shall be a maximum of 0.17 in Zone 1, 0.14 in Zone 2, 0.12 in Zone 3, 0.10 in Zone 4, except Marine, and the same as the frame wall U-factor in Marine Zone 4 and Zones 5 through 8.

  ^c. Basement wall U-factor of 0.360 in warm-humid locations as defined by Figure R301.1 and Table R301.1.

Table R402.4.1.1 is amended to read as follows:

Table R402.4.1.1
Air Barrier and Insulation Inspection Component Criteria

Component	Criteria
Air barrier and thermal barrier	Exterior thermal envelope insulation for framed walls is installed in substantial contact and continuous alignment with building envelope air barrier. Breaks or joints in the air barrier and filled or repaired. Air-permeable insulation is not used as a sealing material. Air-permeable insulation is inside of an air barrier.
Ceiling/attic	Air barrier in any dropped ceiling/soffit is substantially aligned with insulation and any gaps are sealed. Attic access (except unvented attic), knee wall door, or drop down stair is sealed.
Walls	Corners and headers are insulated. Junction of foundation and sill plate is sealed.
Windows and doors	Space between window/door jambs and framing is sealed.
Rim joists	Rim joists are insulated and include an air barrier.
Floors (including above-garage and cantilevered floors)	Insulation is installed to maintain permanent contact with underside of subfloor decking. Air barrier is installed at any exposed edge of insulation.
Crawl space walls	Insulation is permanently attached to walls. Exposed earth in unvented crawl spaces is covered with Class I vapor retarder with overlapping joints taped.
Shafts, penetrations	Duct shafts, utility penetrations, knee walls and flue shafts opening to exterior or unconditioned space are sealed.
Narrow cavities	Batts in narrow cavities are cut to fit, or narrow cavities are filled by sprayed/blown insulation.
Garage separation	Air sealing is provided between the garage and conditioned spaces.
Recessed lighting	Recessed light fixtures are air tight, IC rated, and sealed to drywall. Exception — fixtures in conditioned space.
Plumbing and wiring	Insulation is placed between outside and pipes. Batt insulation is cut to fit around wiring and plumbing, or sprayed/blown insulation extends behind piping and wiring.
