This comprehensive guide provides expert tips for installing a new, sturdy staircase balustrade with balusters. The process involves removing the existing railing, installing the new handrail, marking the layout, and finding the spacing. A strong stair rail is crucial for making stairs safer and easier to use, especially in homes with elderly residents or young children.
Installing a handrail is an essential safety feature required by code, and it is crucial for a well-installed stairway. On a kneewall stair, the balustrade should be centered on the kneewall, while on an open tread stair, the centerline should be 1/2 of the baluster square in from the face of the stringer.
The owner of all dwellings must provide a safe handrail for every stairway that is used or intended for use by the occupant as required by 780 CMR. Handrails should be at a height of 34 to 38 inches measured vertically from the nosing of the treads.
In your area, all railings are to be 42″ as that’s the code, and most contractors will not install shorter than that. Landings must be 7.75″ above the top of the threshold and 36″ wide. Decks over 30″ need a railing, and two or more risers require a handrail.
In summary, this guide provides expert tips for installing stair railings with balusters, ensuring safety and ease of use.

What is the spacing for interior balusters?
The general rule of thumb is to have three balusters per foot to prevent gaps greater than four inches. If you place one baluster every four inches on center, you should be fine. However, consider factors such as uneven measurements, small or larger overhand stair treads, and uneven spacing on each tread. Cheat the design to ensure an even space on both ends of the run. Work your way out until you can fit the balusters on each tread without going over or hitting the upper step. Play around and see what works best for your specific needs.
What is the maximum spacing allowed between balusters?
To determine the number of spindles needed for a deck railing, first determine the space between deck balusters. Building regulations require balusters to be spaced less than 4 inches apart, which can be tested using a “4-inch sphere test”. The general rule is to have three balusters per foot (every 12 inches), although you can place them closer together if desired. The length of your railing also plays a role in determining the number of balusters needed. Use a deck railing and spindle calculator to determine the number of balusters or spindles needed for your project.
What is the residential stair code in Massachusetts?
It is imperative that stairways possess a minimum clear width of 36 inches at all points above the permitted handrail height and below the required headroom height.
What is the code for baluster spacing?
Railing baluster and infill gaps should not exceed 4 inches wide, and the space between decking and bottom rail should not exceed 4 inches. Deck stairs have a 6 inch gap. The deck railing post spacing code requires posts to stay within 8 feet of each other to meet strength requirements. IRC and IBC guidelines dictate strength requirements, including uniform load on guardrails, infills, handrails, concentrated load on guardrails, and linear load on guardrails.
Are spiral staircases legal in Massachusetts?
Spiral stairways are permitted with a clear width of 26 inches (660 mm) and a walkline radius of 24 1/2 inches (622 mm). Additionally, each tread must have a depth of 6 3/4 inches (171 mm) at the walkline.
What is the formula for balusters?
To calculate the center to center spacing of two balusters per tread, divide the tread run by the number of balusters per tread. For a 10-tread run, two balusters per tread pattern, the spacing is 5″. To determine the position of Baluster 1, subtract ½ of the baluster bases width from step 2, resulting in a distance of 7/8″. For Baluster 2, add the baluster spacing to the measurement to get the position of Baluster 2, which is 9 1/8″. This calculation helps in determining the optimal spacing for your tread pattern.
What is the Massachusetts ADA handrail requirements?
Handrails should be situated at a height of 34-38″ above the walking surface, extending a minimum of 12″ beyond the upper and lower limits of a ramp run. They should be continuous, except at points of access, and equipped with guards for landings or ramps exceeding 30″ above the adjacent grade.
