How Tall Does My Deck Railing Need To Be To Meet Building Code?
When planning your family's new outdoor space, it's easy to get caught up in the big decisions. Does your backyard feel like a timeless metal railing system or more like a sleek stainless steel cable railing line? Does your deck have a clear, open vibe that works with glass panel deck railing; or do you want customizable railing options like those offered with composite railing brands?
All these thoughts are crucial to creating a deck design and layout you'll love! One of the first things you should take note of, however, is what railing height you will need to install on your deck. US Building Codes vary from state to state, region to region, and even county to county. Be sure to check your specific local building codes before purchasing and installing your new and improved deck railing.
Here are the general rules of thumb for standard deck railing heights based on building codes across the United States.
What is deck railing code height?
Deck railing height should be a minimum of 36 inches, measuring from the top edge of the top rail down to the deck surface. This applies to the broad majority of the United States for all residential decks, though a few states have different requirements.
In certain areas of the country, such as California and Washington, deck railing must reach a height of 42 inches above the deck surface. You'll also need to meet the higher 42-inch railing requirement for commercial decks and balconies like those attached to restaurants, bars, museums, multi-family homes, condos, or any deck on a third story or higher.
