Stair Handrail on Both Sides: When It Is Required

t361-12

A stair handrail is usually required on both sides when the stair is wide enough to be used by more than one person at a time or when one side is open to a drop. Whether your stair needs one or two handrails depends on the width, the open sides and the rules that apply to your building, which should be confirmed with your engineer.

Why handrails matter on stairs

A stair handrail gives support when going up and down, and it helps people recover their balance if they slip. Many falls on stairs happen to people who are carrying something, who are tired, or who are older and less steady on their feet. A well-placed handrail reduces that risk every day, not only during emergencies.

When planning a renovation, it helps to think about who will use the stair. A family with young children, elderly parents or guests who visit often may benefit more from handrails on both sides than a household where only one adult uses the stair.

When both sides are usually needed

Handrails on both sides are most often recommended in these situations:

The stair is wide, so people can walk side by side or pass each other.
One side is open to a drop, a void or a lower floor.
The stair is a main route in the home, used daily by several people.
The stair is steep, curved or has turns and landings.

In these cases, a single handrail on one wall may leave part of the stair without support.

When one handrail may be enough

A single handrail can be sufficient when the stair is narrow, one side is fully enclosed by a wall, and the stair is used mainly by one or two adults. In a small staircase with a solid wall on one side and a clear, low-risk layout, one well-positioned rail on the open side is often the practical choice.

Even then, check the exact requirement with your engineer, because the answer depends on the stair geometry and the way the building is used.

Standards and what to check

In Israel, railing design is referred to the standard SI 1142, which sets the general requirements for guards and handrails. It is best to treat the standard as a framework and let the engineer confirm the specific values for your project, such as height, spacing and the load the rail must withstand.

Ask your engineer or the building committee whether the stair is considered a shared or common route, since that can change the requirements.

Planning handrails during a renovation

Plan the handrail before the stair is finished or tiled, because mounting points and wall fixings are easier to get right at that stage. Measure the stair width, note the open sides, and take photos from the bottom and the top. Mark where the rail should start and end, and consider extensions at the top and bottom that help users grip before and after the steps.

Measure the width and the height of each side.
Mark any open edges and landings.
Decide on material and finish early.

Materials, finish and fixing

Handrails can be made from iron, stainless steel or aluminum, and each suits different spaces. Iron is strong and can be galvanized and powder coated for outdoor or humid areas, while stainless steel and aluminum offer a clean, modern look with low maintenance. The choice of material affects the fixing method, so confirm the wall or step construction before ordering.

A good handrail should feel comfortable in the hand, with a shape that allows a firm grip and no sharp edges.

Frequently asked questions

Do all stairs need handrails on both sides?

Not always. Two handrails are commonly recommended for wide stairs, stairs with an open side, or stairs used by many people, while a single rail may be enough for some narrow stairs.

Who decides if my stair needs two handrails?

Your structural or safety engineer should confirm the requirement based on the stair layout and applicable standards. Building committees may also have input for shared stairs.

Can I add a second handrail later?

Yes, it is possible, but it is easier and often cleaner to plan both sides during the renovation so that fixings and wall finishes are done correctly once.

What is the main reason to choose two handrails?

Two handrails give support on both hands, which helps people with balance issues, children, and anyone carrying items on a stair that is wide or open to a drop.

Common mistakes to avoid

Many homeowners plan the stair finish first and only then think about the handrail, which leads to poor fixing points or a rail that is hard to grip. Deciding on handrails on both sides early avoids costly changes later.

Our recommendation

Before finalizing the design, ask your engineer to review the stair width, open sides and the applicable standard, then have the handrail measured on site once the walls are ready. Plan both sides together if the stair is used by several people.

Summary

Handrails are usually needed on both sides when the stair is wide, has an open side or is used by many people, and the exact requirement should be confirmed with your engineer during planning.
