Addendum 58f, Pre-Drywall Inspection QA Addendum 58f revises the MINHERS® Chapter 9 to establish clear criteria for the status of Pre-drywall Field QA reviews in the total required Field QA reviews. It is the final version of Standard 58 that will replace interim Addendum 58i July 1, 2022. Addendum 64i, Multi-Family Dwelling Unit Sampling Addendum 64i adds a modification to standard ANSI/RESNET/ICC 301-2019 for the RESNET HERS® which allows use of the RESNET Guidelines for Multifamily Ratings’ inspection and test sampling criteria for determining Sampled Ratings for Dwelling Units in Multifamily buildings. The addendum also extends the current leakage test exception for Puerto Rico and the Virgin Islands until January 1, 2024. Addendum 64i is an interim addendum that takes effect immediately and will be replaced by a final version upon completion of the RESNET consensus standards development process.
