1.6 Class 1 vapor retarders not installed on the interior side of air permeable insulation in exterior below-grade walls 6 Critical Point: Materials that are applied to the inside of exterior walls below grade must have a permeability greater than 0.1 Summary: High perm materials must be used to allow the materials to dry to the inside. On the outside they will have damp-proofing or water-proofing.

Critical Point: Summary: Construction Phase: Inspection: Footnotes: 6. The 2009 IRC defines Class I vapor retarders as a material or assembly with a rating of ≤ 0.1 perm, as defined using the desiccant method with Procedure A of ASTM E 96. The following materials are typically rated at ≤ 0.1 perm and therefore shall not be used on the interior side of air permeable insulation in above-grade exterior walls in warm-humid climates or below-grade exterior walls in any climate: rubber membranes, polyethylene film, glass, aluminum foil, sheet metal, foil-faced insulating sheathings, and foil-faced non-insulating sheathings. These materials can be used on the interior side of walls if air permeable insulation is not present (e.g., foil-faced extruded polystyrene rigid insulation board adjacent to a below-grade concrete foundation wall is permitted). Note that this list is not comprehensive and other materials with a perm rating ≤ 0.1 also shall not be used. Also, if manufacturer specifications for a specific product indicate a perm rating above 0.1, then the material may be used, even if it is in this list. Also note that open-cell and closed-cell foam generally have perm ratings above this limit and may be used unless manufacturer specifications indicate a perm rating ≤ 0.1. Several exemptions to these requirements apply: a. Class I vapor retarders, such as ceramic tile, may be used at shower and tub walls; b. Class I vapor retarders, such as mirrors, may be used if they are mounted with clips or other spacers that allow air to circulate behind them.

Construction Phase: Foundation Inspection: Pre-Framing The drain tile is cut and now does not extend around the entire foundation footing. The drain tile is installed along the bottom of the entire foundation footing.

1.8 Drain tile surrounded with clean gravel and fabric filter 7 C
Critical Point: Moisture Flow — The drain tile should be located below the crawl space/basement floor to remove water before reaching the height of the floor of the crawlspace/basement. Picture Description: BAD- The drain tile should be located below the floor of the crawl space. By having the drain tile above the floor the water level must rise above the crawl space floor level to remove water. This can cause major bulk water issues in the crawl space. GOOD- The drain tile is placed below the floor of the crawl space and drains into the sump pump. This water removal system appropriately removes bulk water from the foundation. Construction Phase: Foundation Inspection: Pre-Framing The drain tile is not installed to terminate properly and will not transport water to the exterior. The drain tile connects to a sump pump which will pump water away from the foundation.

1.8 Drain tile surrounded with clean gravel and fabric filter 7 D
Critical Point: Moisture Flow — Clean gravel and a fabric filter minimize the chances that the drain tile with clog with debris Picture Description: BAD- The drain tile is not surrounded by clean gravel. This increases the chance that drain tile will fail and not appropriately remove water from the foundation. GOOD- Construction Phase: Foundation Inspection: Pre-Framing The gravel surrounding the drain tile is too large and will let too much debris through. GOOD PIC OF DRAIN TILE SURROUNDED WITH GRAVEL

3.1 Step and kick-out flashing at all roof-wall intersections, extending ≥ 4” on wall surface above roof deck and integrated with drainage plane above For homes that don’t have a slab-on-grade foundation and do have expansive or collapsible soils, gutters & downspouts provided that empty to lateral piping that deposits water on sloping final grade ≥ 5 ft. from foundation or to underground catchment system ≥ 10 ft. from foundation.11 Critical Point: The roof plane is sealed and flashed correctly to prevent leaks. The water collected by gutters is deposited in a place that will not cause moisture issues to the home. Summary: By properly flashing at wall intersections and using a membrane in the valleys and at penetrations the potential for leaks is minimized. Gutters appropriately deposit water away from the home as to not introduce water to the foundation/slab/wall system.

3.3 Self-sealing bituminous membrane or equivalent at all valleys & roof deck penetrations In 2009 IECC Climate Zones 5 and higher, self-sealing bituminous membrane or equivalent over sheathing at eaves from the edge of the roof line to > 2 ft. up roof deck from the interior plane of the exterior wall.12 Critical Point: The roof plane is sealed and flashed correctly to prevent leaks. The water collected by gutters is deposited in a place that will not cause moisture issues to the home. Summary: By properly flashing at wall intersections and using a membrane in the valleys and at penetrations the potential for leaks is minimized. Gutters appropriately deposit water away from the home as to not introduce water to the foundation/slab/wall system.

3.1 Step and kick-out flashing at all roof-wall intersections, extending ≥ 4” on wall surface above roof deck and integrated with drainage plane above 10 Critical Point: Moisture Flow- Intersections between roof and walls are flashed appropriately to prevent leaks in the roof. Summary: Wall to roof intersections must be integrated with the drainage plane to manage water and prevent leaks.

Critical Point: Summary: Construction Phase: Inspection: Footnotes: 10. Intersecting wall siding shall terminate 1 in. above the roof or higher, per manufacturer’s recommendations. Continuous flashing shall be installed in place of step flashing for metal and rubber membrane roofs.

3.1 A BAD PIC OF ROOF FELT INSTALLATION
Step and kick-out flashing at all roof-wall intersections, extending ≥ 4” on wall surface above roof deck and integrated with drainage plane above 10 A Critical Point: Moisture Flow- Intersections between roof and walls are flashed appropriately to prevent leaks in the roof. Picture Description: BAD- Step flashing is not present (one solid piece L-flashing) and there is no kick-out flashing. This way of flashing allows water to go under the edge of shingles and can potentially lead to moisture entering the wall system. GOOD- Construction Phase: Roofing Inspection: Final Inspection BAD PIC OF ROOF FELT INSTALLATION GOOD PIC OF PROPERLY LAYERED ROOFING

3.1 Step and kick-out flashing at all roof-wall intersections, extending ≥ 4” on wall surface above roof deck and integrated with drainage plane above 10 B Critical Point: Moisture Flow- Intersections between roof and walls are flashed appropriately to prevent leaks in the roof. By installing the building wrap and the shingles over the flashing the chance of water getting behind the flashing is minimized. Picture Description: BAD- The flashing is not properly integrated with the drainage plane. Water running down the building wrap can go behind the step flashing and water can enter the wall system. GOOD- Step flashing is correctly installed under the roofing material and the house wrap. Construction Phase: Roofing Inspection: Final Inspection The step flashing is not the required height above the roof deck. The step flashing is the correct height above the roof deck.

3.1 Step and kick-out flashing at all roof-wall intersections, extending ≥ 4” on wall surface above roof deck and integrated with drainage plane above 10 C Critical Point: Moisture Flow- Intersections between roof and walls are flashed appropriately to prevent leaks in the roof. Picture Description: BAD- There is no kick-out flashing installed and thus water drains against the wall system. This can cause potentially allow water to enter the wall system. GOOD- Step flashing is correctly installed and extends at least 4” above the roof deck along the wall. Construction Phase: Roofing Inspection: Final Inspection The water-resistant barrier is layered underneath the step flashing and could create a water damage. The water-resistant barrier is layered over the step flashing to provide a complete drainage system.

3.2 For homes that don’t have a slab-on-grade foundation and do have expansive or collapsible soils, gutters & downspouts provided that empty to lateral piping that deposits water on sloping final grade ≥ 5 ft. from foundation or to underground catchment system > 10 ft. from foundation.11 Critical Point: Water collected by gutters is deposited away from the home. Summary: Water is deposited away from the home to minimize the chance that there will be a bulk water issue caused by the gutters/downspouts.

Critical Point: Summary: Construction Phase: Inspection: Footnotes: 11. The assessment of whether the soil is expansive or collapsible shall be completed by a certified hydrologist, soil scientist, or engineer. Gutters shall be not required in dry climates as shown in 2009 IECC Figure and Table A roof design without gutters is also acceptable if it deposits rainwater to a grade-level rock bed with a waterproof liner and a drain pipe that deposits water on a sloping finish grade ≥ 5 ft. from foundation. Rainwater harvesting systems may also be used to meet this requirement when designed to properly drain overflow, meeting the discharge-distance requirements above.

3.2 For homes that don’t have a slab-on-grade foundation and do have expansive or collapsible soils, gutters & downspouts provided that empty to lateral piping that deposits water on sloping final grade ≥ 5 ft. from foundation or to underground catchment system ≥ 10 ft. from foundation.11 A Critical Point: Moisture Flow — Water collected by gutters is deposited at least 5 ft. away from the home. Picture Description: BAD- Downspout terminates under front porch right next to foundation. This increases the potential that there will be moisture entering the crawlspace/basement. GOOD- Downspout terminates at least 5’ from the foundation. Construction Phase: Inspection: Final Inspection The downspout terminates too close to the foundation of the house. The downspout pipes far enough away from the foundation to prevent moisture problems.

3.2 For homes that don’t have a slab-on-grade foundation and do have expansive or collapsible soils, gutters & downspouts provided that empty to lateral piping that deposits water on sloping final grade ≥ 5 ft. from foundation or to underground catchment system ≥ 10 ft. from foundation.11 B Critical Point: Moisture Flow — Water collected by gutters is deposited at least 5 ft. away from the home. Picture Description: BAD- Downspout terminates next to foundation (<5’ from foundation). This increases the potential that there will be moisture entering the crawlspace/basement. GOOD- Downspout terminates into underground catchment system that is at least 10’ from the foundation. Construction Phase: Inspection: Final Inspection The downspout terminates too close to the foundation of the house. The downspout terminates into a catchment system that moves water away from the foundation of the house.

3.2 For homes that don’t have a slab-on-grade foundation and do have expansive or collapsible soils, gutters & downspouts provided that empty to lateral piping that deposits water on sloping final grade ≥ 5 ft. from foundation or to underground catchment system ≥ 10 ft. from foundation.11 C Critical Point: Moisture Flow — When no gutters are present, bulk water from the roof is taken away from the foundation by means of a grade-level rock bed with a waterproof liner and a drain pipe. Picture Description: BAD- No gutters are present and there is no means of taking the bulk water from the roof away from the foundation. GOOD- No gutters are present. However, there is a grade-level rock bed with a waterproof liner and a drain pipe which carries water away from the foundation and deposits it on a sloping grade at least 5’ from the foundation. Construction Phase: Inspection: Final Inspection There are no gutters installed and there is not a proper gravel bed located at the foundation. House without gutters has waterproof liner, drain tile and gravel bed extending more than 5 feet from foundation.

3.2 For homes that don’t have a slab-on-grade foundation and do have expansive or collapsible soils, gutters & downspouts provided that empty to lateral piping that deposits water on sloping final grade ≥ 5 ft. from foundation or to underground catchment system ≥ 10 ft. from foundation.11 D Critical Point: Moisture Flow — Water collected by gutters is deposited at least 5 ft. away from the home. Picture Description: BAD- The rain barrel does not have an overflow drain to take care of the excess water if the barrel is full. This can cause water to be discharged next to the foundation. GOOD- Construction Phase: Inspection: Final Inspection Rain barrel installed without an overflow spout that terminates away from foundation. Rain barrel installed with an overflow spout terminating at least 5 feet from foundation.

3.3 Self-sealing bituminous membrane or equivalent at all valleys & roof deck penetrations 12 Critical Point: All valleys and roof penetrations must have a self-sealing bituminous membrane to prevent leaks. Summary: Roof valleys and roof penetrations are areas that often have shingle failure and are more prone to having water pool. By using a self-sealing bituminous membrane the probability for leaks is lessened.

Critical Point: Summary: Construction Phase: Inspection: Footnotes: 12. Not required in dry climates as shown in 2009 IECC Figure and Table

3.3 Self-sealing bituminous membrane or equivalent at all valleys & roof deck penetrations 12 A Critical Point: Moisture Flow — All valleys must have a self-sealing bituminous membrane to prevent leaks. Picture Description: BAD- There is no self-sealing membrane installed in the valley. Water has frozen in the valley and can potentially cause leaking without a self-sealing membrane. (As water freezes it can work its way under the shingles) GOOD- A self-sealing membrane is being installed in a roof valley. Construction Phase: Roofing Inspection: Framing There is not a self-sealing bituminous membrane installed at the valley of the roof. There is a self-sealing bituminous membrane installed at the valley of the roof prior to the roof felt.

3.3 Self-sealing bituminous membrane or equivalent at all valleys & roof deck penetrations 12 A Critical Point: Moisture Flow — All roof penetrations must have a self-sealing bituminous membrane to prevent leaks. Picture Description: BAD- GOOD- Construction Phase: Roofing Inspection: Framing Inspection BAD PIC OF ROOF WITHOUT MEMBRANE INSTALLED There is a properly installed and layered self-sealing bituminous membrane installed at the roof penetration.

3.4 In 2009 IECC Climate Zones 5 and higher, self-sealing bituminous membrane or equivalent over sheathing at eaves from the edge of the roof line to > 2 ft. up roof deck from the interior plane of the exterior wall.12 Critical Point: In cold climates, self-sealing bituminous membrane must be installed at the eaves. This membrane must extend at least 2’ up the roof deck from the wall plane. Summary: In cold climates, there is a potential for ice dams that can cause water to pool at the eaves. If a self-sealing bituminous membrane is not installed at the eaves it is very probable that there will be leaks.

Critical Point: Summary: Construction Phase: Inspection: Footnotes: 12. Not required in dry climates as shown in 2009 IECC Figure and Table

3.4 A BAD PIC OF NO MEMBRANE AT EAVES

SECTION 4. WATER-MANAGED BUILDING MATERIALS
4.1 Wall-to-wall carpet not installed within 2.5 feet of toilets, tubs, and showers 4.2 Cement board or equivalent moisture-resistant backing material installed on all walls behind tub and shower enclosures composed of tile or panel assemblies with caulked joints. Paper-faced backerboard shall not be used 13 Critical Point: Materials that are installed do not have high moisture content and will not cause moisture issues during the life of the home. Summary: Moisture issues can cause durability issues and indoor air quality issues.

4.3 In Warm-Humid climates, Class 1 vapor retarders not installed on the interior side of air permeable insulation in above-grade walls, except at shower and tub walls Building materials with visible signs of water damage or mold not installed Interior walls not enclosed (e.g., with drywall) if either the framing members or insulation products have high moisture content 15 Critical Point: Materials that are installed do not have high moisture content and will not cause moisture issues during the life of the home. Summary: Moisture issues can cause durability issues and indoor air quality issues.

4.1 Wall-to-wall carpet not installed within 2.5 feet of toilets, tubs, and showers Critical Point: No carpet should be installed within 2.5’ of toilets, tubs, and showers. A flooring material that does not hold water should be used here. Summary: Around toilets, tubs and showers there is a high potential for water to contact the flooring material. Carpet can hold moisture and cause indoor air quality issues.

4.1 Wall-to-wall carpet not installed within 2.5 feet of toilets, tubs, and showers A Critical Point: Moisture Flow — No carpet should be installed within 2.5’ of toilets, tubs, and showers. A flooring material that does not hold water should be used here. Picture Description: BAD- Carpet is installed next to the bath tub. GOOD- There is no carpet within 2.5’ of the tub or the toilet. Construction Phase: Flooring- Towards the end of construction. Inspection: Final inspection There is carpet installed too close to the plumbing fixtures in the bathroom. There is no carpet installed in the bathroom.

4.2 Cement board or equivalent moisture-resistant backing material installed on all walls behind tub and shower enclosures composed of tile or panel assemblies with caulked joints. Paper-faced backerboard shall not be used 13 Critical Point: A moisture-resistant backing material is installed on walls behind tubs and shower enclosures that have the potential for failure and moisture to pass behind the shower or tub. Summary: Tile and panel tub surrounds and showers have joints that can fail and allow water to pass behind the tub or shower. This moisture can cause durability issues and/or indoor air qualities.

Critical Point: Summary: Construction Phase: Inspection: Footnotes: 13. Monolithic tub and shower enclosures (e.g., fiberglass with no seams) are exempt from this backing material requirement unless required by the manufacturer. Paper-faced backerboard may only be used behind monolithic enclosures and only if it meets ASTM mold-resistant standards ASTM D3273 or ASTM D6329.

4.2 A No backing installed behind shower enclosure.
Cement board or equivalent moisture-resistant backing material installed on all walls behind tub and shower enclosures composed of tile or panel assemblies with caulked joints. Paper-faced backerboard shall not be used 13 A Critical Point: Moisture Flow — A moisture-resistant backing material is installed on walls behind tubs and shower enclosures that have the potential for failure and moisture to pass behind the shower or tub. Picture Description: BAD- GOOD- Construction Phase: Rough-in plumbing Inspection: Framing Inspection No backing installed behind shower enclosure. Foam board taped at seams installed behind shower enclosure.

4.2 B BAD PIC OF NON MOISTURE RESISTANT MATERIAL BEHIND TUB/SHOWER
Cement board or equivalent moisture-resistant backing material installed on all walls behind tub and shower enclosures composed of tile or panel assemblies with caulked joints. Paper-faced backerboard shall not be used 13 B Critical Point: Moisture Flow — A mold-resistant backerboard is used behind monolithic tub/shower enclosures to prevent mold growth. Picture Description: BAD- There is no mold-resistant backerboard installed behind the shower. GOOD- There is a mold-resistant backerboard installed behind the shower. Construction Phase: Rough-in plumbing Inspection: Framing Inspection BAD PIC OF NON MOISTURE RESISTANT MATERIAL BEHIND TUB/SHOWER Moisture resistant backing material has been used above the tub enclosure.

4.3 In Warm-Humid climates, Class 1 vapor retarders not installed on the interior side of air permeable insulation in above-grade walls, except at shower and tub walls 6 Critical Point: All materials used on the interior side of exterior walls has a permeability rating of 0.1 or more. This allows moistures to pass through the wall systems freely. Summary: In warm-humid climates moisture flows both directions through the wall depending on the season. Moisture flows from hot to cold and wet to dry. By having a high perm rating the moisture is not trapped in the wall.

Critical Point: Summary: Construction Phase: Inspection: Footnotes: 6. The 2009 IRC defines Class I vapor retarders as a material or assembly with a rating of ≤ 0.1 perm, as defined using the desiccant method with Procedure A of ASTM E 96. The following materials are typically rated at ≤ 0.1 perm and therefore shall not be used on the interior side of air permeable insulation in above-grade exterior walls in warm-humid climates or below-grade exterior walls in any climate: rubber membranes, polyethylene film, glass, aluminum foil, sheet metal, foil-faced insulating sheathings, and foil-faced non-insulating sheathings. These materials can be used on the interior side of walls if air permeable insulation is not present (e.g., foil-faced extruded polystyrene rigid insulation board adjacent to a below-grade concrete foundation wall is permitted). Note that this list is not comprehensive and other materials with a perm rating ≤ 0.1 also shall not be used. Also, if manufacturer specifications for a specific product indicate a perm rating above 0.1, then the material may be used, even if it is in this list. Also note that open-cell and closed-cell foam generally have perm ratings above this limit and may be used unless manufacturer specifications indicate a perm rating ≤ 0.1. Several exemptions to these requirements apply: a. Class I vapor retarders, such as ceramic tile, may be used at shower and tub walls; b. Class I vapor retarders, such as mirrors, may be used if they are mounted with clips or other spacers that allow air to circulate behind them.

4.4 Building materials with visible signs of water damage or mold not installed Interior walls not enclosed (e.g., with drywall) if either the framing members or insulation products have high moisture content 15 Critical Point: Water damage and mold is not present on any material that is installed on the home. Summary: By not installing any water damaged/moldy materials in the home the potential for mold and durability issues in minimized.

Critical Point: Summary: Construction Phase: Inspection: Footnotes: 14. If mold is present, effort should be made to remove all visible signs of mold using detergent or other method. If removal methods are not effective, then the material shall be replaced. 15. For wet-applied insulation products, follow manufacturer’s drying recommendations. As guidance, EPA recommends that lumber not exceed 18% moisture content.

4.4-5 Building materials with visible signs of water damage or mold not installed 14 A Critical Point: Moisture Flow — Storing building materials in a dry location minimizes the potential for mold and water damage to the building materials. Picture Description: BAD- Materials are stored in a location that has lots of moisture present. GOOD- Materials kept on pallets despite the ground being very wet they are wrapped and dry still. Construction Phase: Pre-Construction & During Construction Inspection: Throughout Construction Building materials are being stored outdoors with no protection from weather. Shingles kept wrapped and on pallets to prevent from getting wet.

4.4-5 Building materials with visible signs of water damage or mold not installed 14 B Critical Point: Moisture Flow — Materials installed do not have any mold or water damage present. Picture Description: BAD- Materials installed have mold present. GOOD- Materials installed are free of water damage and mold. Construction Phase: Pre-Construction & During Construction Inspection: Throughout Construction Building materials with visible signs of mold have been used. Building materials were kept dry and free of mold.

4.4-5 Interior walls not enclosed (e.g., with drywall) if either the framing members or insulation products have high moisture content 15 C Critical Point: Moisture Flow — No high moisture content materials are enclosed in the wall system Picture Description: BAD- Materials that have high moisture content have been installed ***NOT A WALL SYSTEM, JOIST HANGER PRESENT*** GOOD- Moisture meter shows that the wood has a moisture content below 18%. Therefore it is acceptable to enclose this material. Construction Phase: Drywall Inspection: Insulation Inspection Building materials have signs of water damage and high moisture content. A moisture meter verifies that the moisture content of the framing is below the recommended 18%.

4.4-5 Interior walls not enclosed (e.g., with drywall) if either the framing members or insulation products have high moisture content 15 D Critical Point: Moisture Flow — No high moisture content insulations are enclosed in the wall system Picture Description: BAD- GOOD- Construction Phase: Drywall Inspection: Insulation Inspection BAD PIC OF WET BLOWN INSULATION PRODUCT GOOD PIC OF WET BLOWN INSULATION PRODUCT
