If you get ready to develop a new home or renovate a old one and also have handrails you wish to incorporate then you will want to get current on basic interior handrail code requirements.
Before we start by getting discussing basic handrail codes we have to make a clear distinction between handrails and top rails. A top rail is usually a barrier that keeps people from falling over. The handrail will be the part you physically grip as you climb the stirs. In this article as well as discussing handrails and never top rails unless the highest rail can also be the handrail.
When it visit handrails you’ll find three code requirements that should be followed:
Handrail hights are quite obvious. OSHA states the handrail hight should be no less than 30 inches to your maximum of 37 inches high. This may seem low for a few locations fresh fruits you can also employ a higher top rail in the event the site is intimidating. IBC or International Building Code requires handrails to be at the least 42 inches unless it is often a 3 story building in that case your minimum hight is 36 inches. As a fabricator of metal handrails I typically make mine 36 inches high for many residential projects.
Handrail dimension is another issue so that as a rule of thumb they will not exceed 2 ” wide and you need to leave at the very least 1.5 inches of space involving the handrail plus the wall or top rail to allow for easy grabbing without getting the hand stuck between rail and wall.
Baluster spacing can be a major safety issue with regards to young children. The baluster may be the picket or spindle on the handrail and spacing needs to become tight enough that your toddler cannot slip over the spaces. The spacing rule says that your 4 3/8 inch ball shall not pass from the spaces. What this means is usually a building inspector will possess a 4 3/8 inch ball with him or her and if it passes through any baluster after that your handrails will not be up to code. Many people think the rule is usually a 4 inch ball however it is actually a 4 3/8 inch ball that cannot pass throughout the spaces.
Finally in case you are planing to get some new home or create a new one you should check with any local building inspector. Some cities and counties may have different requirements. As a guide stick to your handrail hight of 36 to 37 inches, allow no less than 1 1/two inches of space to your hand to fit between handrail and wall or top rail whilst your buluster spacing to 4 inches or less.
