Deck Railing Height Requirements

Why Railing Height Matters

Deck railing isn’t just about aesthetics—it plays a vital role in keeping people safe. Whether you’re building a new deck or upgrading an existing one, understanding railing height requirements helps you meet building codes and avoid costly mistakes.

General Railing Height Code

In most areas, including Georgia, the International Residential Code (IRC) sets the standard:

• Decks 30 inches or higher off the ground require a guardrail.
• Minimum guardrail height is 36 inches from the deck surface to the top of the rail.
• Baluster spacing must not allow a 4-inch sphere to pass through—this prevents small children from slipping through.

Stair Railing Requirements

If your deck includes stairs, additional rules apply:

• Handrails are required on stairs with four or more risers.
• Minimum height for stair railings is 34 inches, and the maximum is 38 inches, measured from the stair nosing.

Local Variations to Watch For

While the IRC provides a baseline, local building codes may vary slightly. Always:

• Check with your city or county permitting office before construction.
• Hire a licensed contractor who is familiar with local regulations.
• Request inspections to ensure compliance during and after the build.

When a Railing May Not Be Required

Not all decks need a railing. If your platform is under 30 inches in height, you may skip the guardrail—but it’s still recommended for added safety, especially in homes with kids or pets.

Design Considerations Beyond Code

While code compliance is essential, railing height can also affect your deck’s look and feel:

• Taller railings offer more privacy but can obstruct views.
• Modern designs may include cable or glass infill to maintain openness while staying safe.
• Mixing materials—like wood with aluminum or steel—can boost both strength and style.

Safe, Stylish, and Code-Compliant

Your deck railing should be a seamless combination of form and function. By staying informed and following the right height requirements, you protect your family while enhancing your home’s outdoor appeal.
