The building code requires handrails for stairs with two or more risers, measured from the tread nosing or ramp surface. Handrail height must be between 34 and 38 inches, with two exceptions: 1) a volute over the lowest tread, and 2) the transition from handrail to guard or at the start of a flight. Handrails must meet the required grip size per section R311.7.8.5. Handrails are typically mandated for stairs with three or more steps, and some codes may also require handrails for ADA ramps with a 6″ rise. Handrails are designed to provide guidance and must be provided on not less than one side of each flight of stairs with four or more risers. A small stairway of just three steps will require a handrail if it rises more than 1 meter in total, depending on the height and thickness of the steps. In general building codes, anything that requires four or more steps from platform to platform needs a handrail. For flights with three or more risers, a handrail that can be gripped to one side of the steps provides additional support.

Handrails should be installed on either side of flights wider than 1000mm and sit 850-1000mm above the pitch line. Front door step regulations in the UK, approved document K, provide additional details for entrance steps within a building structure, not just on an approach route.
Do I need a handrail for 3 steps on a deck?
The International Rail Code (IRC) mandates that deck stairs on residential properties must have at least one set of railings and a handrail installed on stairs with four or more risers. The handrail must be at least 34 inches high and no higher than 38 inches when measured from the sloped plane. The handrail must be between 1 ¼ inch and 2 inches in diameter for a secure grip.

Handrails must be continuous, including landings, and installed on both sides of the ramp. The top rail height should not exceed 965mm or 865mm, and the distance between the handrail and the wall should not exceed 4. 5 inches. Prefabricated brackets can be purchased to meet building code standards.
Guardrails should be installed for raised platforms if the total surface reaches the 600mm threshold relative to the deck’s position to the adjacent ground. The guards should have a sufficient barrier, not spaced more than four inches apart, and be childproof and pet-proof. The height of the guard must not be less than two feet, 11 inches if the elevation is not more than five feet, 11 inches. The top rail should not be less than 36 inches from the deck surface in residential dwellings or 46 inches for commercial establishments.
If glasses are used instead of pickets, the material should be tempered or laminated for safety reasons. Only credited companies can install glass on guards. The guards must be designed to take the load of a person leaning into it, and the Occupational Health and Safety Administration requires a minimum of 200 pounds of force on top of the rail.
Building a deck typically costs between $4, 000 and $11, 000, with homeowners spending about $7, 500 on average.

What is the code on an exterior handrail?
Handrails are essential for stair and ramp construction, typically installed on both sides of stairways, ramps, ramped aisles, and stepped aisles. They should have a uniform height of 34-38 inches, a minimum clearance of 2. 25 inches, and a easy-to-grasp shape. Handrails should withstand a 200-pound concentrated load applied in an upward or downward direction, have minimal obstruction, continuous gripping surfaces, no sharp or abrasive elements, rounded edges, and no rotation within their fittings. They should extend horizontally above the landing for a minimum of 12″ beyond the bottom and top of the stair and ramp runs.
Is one handrail enough?
The IBC’s section 1014. 9 mandates the installation of intermediate handrails on each side of commercial buildings, providing guidance on stairs with two or more risers or ADA ramps with a 6″ rise. Handrails are required on both sides of ramps and stairs in commercial buildings. However, handrails are not necessary on walking surfaces with a running slope less than 1:20, as the 2010 ADASAD recommends a maximum height of 28″ for children’s railings and a clearance of at least 9″ between them and the adult railing.
How many steps can you have on a deck without railing?
The code does not apply to decks 30 or more inches in height. However, in the event that stairs have four or more risers, a handrail is required.
