You may feel secure on stairs without a handrail, but if you want to sell your home, California building codes require a handrail installation any time there are more than four steps. The handrail shouldnât extend into the width of the stairs more than 3 1/2 inches.If you need to install a handrail on interior stairs in your home, you must set it between 34 and 38 inches above the stair treads. Wood handrails are acceptable.ou also need additional brackets, spaced no more than 4 feet apart in the middle of the handrail to provide additional support. Make a vertical mark on the chalk line over the studs where you intend to hang the brackets. Measure and mark 2 3/4 inches below each of these marks for the top of the bracket.
