Understanding Deck Railing Requirements
Proper deck railing installation is crucial for safety and code compliance.
- Height Requirements Residential deck railings must be at least 36 inches high, 42 inches for commercial applications.
- Post Spacing Posts should be spaced according to local building codes, typically 4-8 feet apart.
- Baluster Spacing Balusters must be spaced so a 4-inch sphere cannot pass through.
- Load Requirements Railings must withstand a minimum 200-pound concentrated load.
