TL;DR:
The International Code Council has opened a 45-day ANSI public review period for the next edition of ICC 600, the Standard for Residential Construction in High-Wind Regions. The draft revisions aim to align ICC 600 with revisions to the wind provisions in ASCE 7-22. The public comment window runs through June 1, 2026. This development matters for design practice in high wind areas and for PE exam candidates who study wind design in ASCE 7-22 and related building codes. Engineering teams should plan to review the draft, consider how changes could affect detailing for walls, roofs, connections, and fasteners, and map out documentation updates if final changes are adopted by their jurisdiction.

What is happening now and why it matters
ICC has announced a 45-day public review period for the upcoming ICC 600 update, which covers Residential Construction in High-Wind Regions. The draft revisions have been posted for ANSI public comment, with comments due by June 1, 2026. The update is being developed to reflect changes already taking place in wind design provisions, specifically the wind provisions in ASCE 7-22. For engineers designing homes in hurricane-prone or high-wind regions, the draft represents the next set of wind-resistance expectations that could influence prescriptive and performance-based approaches, detailing, and construction requirements. (iccsafe.org)
How this connects to ASCE 7-22 wind provisions
ASCE 7-22 introduces updated wind load provisions, including refinements to how wind pressures are calculated for components and cladding and changes to tornado and high-wind considerations. The ICC 600 update explicitly ties its revisions to the wind provisions in ASCE 7-22, ensuring harmonization between the national design loads standard and the high-wind residential construction standard used in practice. Practicing engineers should review both documents to understand how new wind loads and construction requirements could alter verification of roofs, walls, and fastener details in high wind regions. (iccsafe.org)
Implications for practicing engineers and project teams
- Design and detailing: The draft ICC 600 update will likely influence required detailing for wind resistance, including roof assemblies, wall coverings, and connections in high-wind regions. Since the update is aligned with ASCE 7-22, engineers should anticipate changes in allowable prescriptive approaches and in performance-based considerations for residential construction in wind-prone areas. Planning for updated materials, fasteners, and attachment methods may be prudent as the final language is released. (iccsafe.org)
- Document management and plan reviews: Updates to ICC 600 often cascade to local code adoption, plan-check checklists, and inspection expectations. Project teams should prepare to revise the project manuals, detailing drawings, and quality-control procedures to reflect the final ICC 600 language once adopted by jurisdictions. (iccsafe.org)
- Training and knowledge refresh: For engineers and constructors who rely on high-wind provisions, the public review period is an opportunity to refresh knowledge on wind design collaboration between model codes. Training should emphasize how ASCE 7-22 wind provisions interact with ICC 600 updates and how this affects project-specific design loads and detailing decisions. (iccsafe.org)
Guidance for PE exam candidates in light of the update
- Expect cross-referencing between ASCE 7-22 and ICC 600: The pending ICC 600 update is designed to align with ASCE 7-22 wind provisions, so PE candidates should ensure solid familiarity with ASCE 7-22 wind load rules, tornado provisions, and high-wind region considerations as they relate to residential construction. Reviewing both documents will help with problem-solving on wind-related questions that may appear on structural or building design exams. (iccsafe.org)
- Use the public-comment period as a study cue: While preparing for the PE exam, use the draft language as a real-world example of how code changes propagate from national design standards into product standards used in practice. This helps translate code theory into practical exam-ready workflows such as checking assumptions, verifying design pressures, and documenting compliance paths. (iccsafe.org)
- Track jurisdiction adoption: Because ICC 600 and ASCE 7-22 changes travel through state and local adoption cycles, exam questions often test understanding of how differences between model codes and local amendments can affect design requirements on a project. Candidates should stay alert to state updates and typical adoption timelines. (iccsafe.org)
How to participate and what to expect next
- Public comment process: Submissions are accepted via ICC’s online portal. The 45-day window runs through June 1, 2026, offering professional engineers a chance to influence the final language prior to publishing. Engagement now helps ensure that practical field concerns are addressed in the final ICC 600 standard. (iccsafe.org)
- Next steps after the comment period: Following the public review, ICC will review comments and finalize the ICC 600 update. Jurisdictional adoption typically follows, varying by state and locality. Engineers should monitor their jurisdiction’s code adoption timelines and plan for updated requirements to become enforceable on future projects. (iccsafe.org)
Practical takeaways for engineers and project teams
- Plan to review the draft ICC 600 language in parallel with ASCE 7-22 updates and prepare for potential changes to wind design criteria and construction detailing in high wind regions.
- Update project documentation and QC procedures in anticipation of final ICC 600 changes, especially for residential projects in hurricane-prone areas.
- For PE candidates, prioritize a strong grasp of ASCE 7-22 wind provisions and how they interrelate with ICC 600 to navigate exam questions that test wind resistance and high-wind region requirements.
Why this matters in 2026
Wind resistance remains a critical design driver for residential construction in high wind regions. The ICC 600 update represents a concerted effort to harmonize residential wind provisions with the broader wind design framework in ASCE 7-22, aiming to reduce ambiguity and improve constructability in the field. The public review period through June 1, 2026 provides a concrete, time-bound opportunity to influence the final standard and to align practice with evolving national guidance. (iccsafe.org)
