Performance-Based Codes and Alternative Means Compliance
Performance-based codes are building regulations that specify the desired outcomes or performance levels for construction projects, rather than prescribing specific methods or materials. Alternative means compliance allows builders to meet these outcomes using innovative designs, materials, or technologies not explicitly mentioned in traditional codes. This approach encourages creativity, flexibility, and the adoption of new construction technologies while ensuring that safety, functionality, and regulatory objectives are still achieved.

💡 Key Takeaways
- Understand what performance-based codes are and how they measure safety outcomes instead of fixed prescriptions.
- Learn how to demonstrate compliance through performance-based design, testing, and evidence to satisfy the AHJ.
- Identify what constitutes an Alternative Means of Compliance (AMC) and when it can be used in project design.
- Know the typical steps to obtain AMC approval, including documentation, simulations, and coordination with the Authority Having Jurisdiction.
❓ Frequently Asked Questions
What are performance-based codes?
Codes that specify outcomes (such as safety, energy efficiency, or accessibility) rather than prescribing exact construction methods. Designers can choose how to meet the outcomes as long as performance is demonstrated.
What is Alternative Means of Compliance (AMC) in building codes?
AMC is a pathway within performance-based codes that lets you use alternative designs, materials, or methods if you can prove the project meets the code’s performance criteria through analysis, testing, or verification.
How does a project demonstrate compliance under AMC?
Through approved methods like engineering calculations, computer modeling, tested assemblies, third-party certifications, and a compliance narrative showing equivalence to the prescriptive requirements.
Who approves AMC and what documentation is typically needed?
The local Authority Having Jurisdiction (AHJ) reviews and approves. Typical docs include design calculations, test reports, referenced standards, drawings, and a clear AMC narrative showing how the project meets performance criteria.
When might performance-based or AMC approaches be preferred?
When site conditions, innovative materials, or unique project goals require flexibility, or to optimize performance, cost, or sustainability while meeting safety and code goals.
