The Bay Area follows the California Building Code (CBC) for railing requirements. Here are some key points to remember.
The Bay Area’s Railings Codes In 2024
- Height: A standard guardrail, which includes most railings, needs a vertical height between 42 inches and 45 inches measured from the top rail to the walking surface (floor, platform, etc.)
- Stair Railings vs. Guards: There’s a distinction between stair railings and stair guards. Stair railings run along the inclined part of the stairs, while guards are typically for flat landings, balconies, or decks. The height requirements apply to both.
- Handrail Grasp: The handrail, the part you hold onto, should be between 34 inches and 38 inches high, measured from the walking surface to the top of the handrail.
- Spacing: Railings, particularly cable railings, need to be designed to prevent a 4-inch diameter sphere (4 3/8 inches for stairs) from passing through any gaps. This ensures safety for small children.
Important Note: While the CBC provides a general framework, local municipalities may have additional requirements or amendments to the code.
