The Georgia Department of Community Affairs (DCA) had already issued its notice of intent and received final approval from the DCA Board in August 2025. Grace periods for implementation are left to local jurisdiction, meaning project teams should prepare for a direct transition from IBC 2018 to IBC 2024, and coordinate closely with Building Officials for projects being permitted around the transition date.
These Georgia building code changes will affect many aspects of structural design, from new tornado and flood provisions to improved seismic models, occupancy categories, and concrete requirements. Below, we highlight the major updates and flag what Georgia AEC firms and building owners need to know as they prepare for projects under the new code.
Key Takeaway
Effective Date: January 1, 2026
Adoption: International Building Code (IBC) 2024 with Georgia Amendments
Transition: Grace periods for the transition between IBC 2018 and IBC 2024 are left to individual jurisdictions
Why the 2026 Georgia Building Code Update Matters
The Georgia building code changes in 2026 represent the most significant structural code updates since the adoption of IBC 2018 six years ago. From risk categories to tornado, flood, and seismic provisions, the new code will shape how facilities are designed and built across the state. Design teams and owners have an opportunity to work closely together, learn collectively, and adapt to the new requirements – strengthening teamwork and building a deeper understanding through this transition.
Diving into these changes now will allow AEC professionals and building owners to keep future projects on track, especially those scheduled for permitting after the effective date.
Major Structural Design Changes in IBC 2024
Risk Category Updates
Skilled nursing facilities will now be classified as Risk Category IV buildings. This aligns them with hospitals and other essential facilities, recognizing the challenges of evacuating residents during disasters. Structural loading requirements for these facilities will increase accordingly.
Tornado Load Requirements
For the first time, IBC 2024 introduces tornado load design for Risk Category III and IV facilities. In Georgia, this applies to schools, public assembly spaces, hospitals, and emergency response buildings. The new provisions are targeted toward smaller tornadoes (EF-0 to EF-1) but still represent a major shift in design approach. Owners of critical facilities should expect more robust wind-resistant detailing to improve resilience and life safety. It is important to understand that the new tornado provisions are intended to make buildings “tornado proof”; storm shelters, which largely remain voluntary, remain the safest place to shelter during a tornado.
Flood Design Standards
Georgia is adopting the latest flood-resistant design standard, reflecting a national trend toward stronger flood resilience in new construction. Code requirements expand from the current 100-year flood to the 500-year flood (a 0.2% annual chance event). This means facilities in flood-prone areas may need additional elevation, foundation protection, or floodproofing, ultimately reducing insured losses from flood events.
Seismic Code Changes
Georgia will implement updated ground motion models, reflecting improved research on East Coast earthquake risks. While many inland structures may benefit from lower seismic demands, projects on soft soil or coastal sites may require additional geotechnical investigations to confirm site-specific design values. This change underscores the importance of early coordination with Geotechnical Engineers.
Existing Building Adoption
Renovation projects in Georgia will now follow the International Existing Building Code (IEBC), using either the Prescriptive or Performance methods as the basis for renovation work. This sunsets previous Chapter 34 provisions and incorporates key updates, while the full IEBC remains a permissive code. The full IEBC remains permissive, but Georgia’s adoption improves alignment with national standards, offering owners and design teams a more predictable renovation framework.
Concrete Code Updates
Georgia will adopt the latest edition of American Concrete Institute (ACI) 318. A notable change is the treatment of punching shear in elevated slabs. To meet updated requirements, many podium slabs may need increased thickness, which could affect both structural configuration and cost. This update reflects the latest science in structural safety and design.
Who Will Be Affected by in 2026?
These Georgia building code updates will impact multiple stakeholders:
- Architects & Engineers: must account for updated load and detailing provisions and code references in design.
- Contractors & Developers: should anticipate potential cost and scope adjustments due to thicker slabs, tornado resilience, and flood standards.
- Owners & Operators: especially nursing homes, hospitals, schools, and emergency facilities, will see increased requirements for structural safety.
Preparing for Georgia’s 2026 Building Code Changes
Following the effective date, it is important to:
- Review the proposed amendments available on the Georgia DCA website.
- Plan for additional geotechnical investigations on seismic-sensitive sites.
- Anticipate design changes for foundations, podium slabs, and tornado load requirements.
- Begin coordinating with structural engineers, contractors, and any other affected stakeholders early for any project scheduled for 2026.
Because grace periods are handled at the jurisdiction level, early collaboration with the Building Official is encouraged for projects submitted for permit around the effective date.
