In the event that an item cannot be inspected by the verifier, the
builder may assume responsibility for verifying that the item has met
the requirements of the checklist. This option is available at the
discretion of the verifier but may not be used to verify more than three
(3) items on the checklist. This responsibility will be formally
acknowledged by the builder signing off on the checklist for the item(s)
that they verified. 

Where setbacks limit space to less than 10 ft., provide swales or drains
designed to carry water from foundation. Backfill tamping is not
required if proper drainage can be achieved using non-settling compact
soils, as determined by a certified hydrologist, soil scientist, or
engineer.

Sheeting shall be > 6 mil polyethylene sheeting overlapped 6-12 in. at
joints. Polyethylene sheeting is not required in Dry (B) climates as
defined by IECC 2004 Figure 301.1, except in U.S. EPA Zone 1 Radon
areas. In areas with free-draining soils, identified as Group 1 in the
IRC by a certified hydrologist, soil scientist, or engineer through a
site visit, a gravel layer or geotextile matting is not required.

It is recommended, but not required, that sheeting be > 10 mil
polyethylene. Polyethylene sheeting is not required for raised-pier
foundation with no walls, in Dry (B) climates as defined by IECC 2004
Figure 301.1, or in Marine climates as defined by IECC 2004 Figure 301.1
and Table 301.1 if no air handler or return ducts are installed in the
crawlspace.

Sump pump covers shall be mechanically attached with full gasket seal or
equivalent.

Protected drain tile shall be installed at the footings of basement and
crawlspace walls, level or sloped to discharge to outside grade
(daylight) or to a sump pump. The top of each drain tile pipe shall
always be below the bottom of the concrete slab or crawlspace floor.
Each pipe shall be surrounded with at least 6 inches of ½ to ¾ inc.
washed or clean gravel. The gravel layer shall be fully wrapped with
fabric cloth to prevent fouling of the drain tile.

Drainage systems equivalent to flashing are also allowed.  

Any of the following systems may be used: a monolithic weather-resistant
barrier (i.e., house wrap) sealed or taped at all joints; weather
resistant sheathings (e.g., faced rigid insulation) fully taped at all
“butt” joints; or lapped shingle-style building paper or felts.

Include pan flashing at sills, side flashing that extends over pan
flashing, and top flashing that extends over side flashing.

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.

Not required in dry climates as shown in IECC 2004 Figure 301.1 and
Table 301.1.  

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.

Paper-faced wall board does not meet this requirement.

For wet-applied insulation products, follow manufacturer’s drying
recommendations. As guidance, note that lumber should not exceed 18%
moisture content.
