From the 2018 IECC: R402.4.1.2 Testing.
The building or dwelling unit shall be tested
and verified as having an air leakage rate
not exceeding (3.00 ACH50) three air
changes per hour in Climate Zones 3
through 8. Testing shall be conducted in
accordance with RESNET/ICC 380, ASTM
E779 or ASTM E1827 and reported at a
pressure of 0.2 inch 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.

Per the 2021 IECC: (Compliance method allowed by Garfield County for this unit)
R402.4.1.2 Testing. The building or dwelling unit shall be tested for air leakage. The maximum air leakage rate for any
building or dwelling unit under any compliance path shall not exceed 5.0 air changes per hour or 0.28 cubic feet per minute
(CFM) per square foot [0.0079 m3/(s x m2)] of dwelling unit enclosure area. Testing shall be conducted in accordance with
ANSI/RESNET/ICC 380, ASTM E779 or ASTM E1827 and reported at a pressure of 0.2 inch 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 have been sealed.
Exception: When testing individual dwelling units, an air leakage rate not exceeding 0.30 cubic feet per minute per
square foot [0.008 m3/(s x m2)] of the dwelling unit enclosure area, tested in accordance with ANSI/RESNET/ICC 380,
ASTM E779 or ASTM E1827 and reported at a pressure of 0.2 inch w.g. (50 Pa), shall be permitted in all climate zones for:
1. Attached single and multiple -family building dwelling units.
2. Buildings or dwelling units that are 1,500 square feet (139.4 m2) or smaller.
801 CFM50/3,874 sq ft Surface Area = .207 CFM/sq ft Surface Area. Unit Passes.
