Helpful Tips. Any deck that is 30 inches or more above ground must have a railing, as well as a building permit for that deck, if it is an addition to a building. If a deck is below 30 inches, it is the owner's choice to install railings, though they still must adhere to the mandated rules.ommercial railings necessitate a higher railing at 42 inches, as regulated by the IBC. Another specification for railings include rail spacing that is less than 4 inches apart, making sure that a ball or sphere of 4 inches in diameter cannot push in between for safety parameters.
Deck Railing Codes All decks higher than 30 above grade must have a guardrail. If you choose to install a guardrail on a deck lower than 30 you must still meet code requirements. Decks attached to single family detached homes are regulated under the rules of the International Residential Code (IRC). The IRC requires guardrails to be at lest 36 in height measured from the deck surface to the top of the rail.
