Choose between EIFS with drainage and barrier EIFS for a residential project and confirm which code requires

Steps

1. Check the IRC wall-covering chapter's EIFS section: EIFS with drainage is required over most residential wall assemblies, with an exception generally carved out for concrete or masonry substrates
2. Confirm the water-resistive barrier requirement between the EIFS and sheathing meets the code section's referenced compliance path
3. Verify termination height above grade and flashing tie-ins meet the code minimums cited in the same section
4. If a barrier EIFS is proposed instead, confirm the AHJ will accept it only where the code exception applies (e.g., masonry/concrete substrate) or via an approved alternative/ESR
5. Document the drainage plane and weep/drainage track detailing in the submittal set for inspection sign-off
