The size and shape of outdoor steps in new buildings is governed by the local Building Regulations. This control is mainly directed at disabled access to the main entrance but there is always a legal obligation to design safely. The rise and going (tread) dimensions of a formal flight of stairs should be constant.
What are the Building Regulations for steps?
The following rules must be met: The individual rise must be between 150mm and 220mm. The individual going must be between 220mm and 300mm. The Pitch of the stair cannot be greater than 42 degrees.
Do garden steps need a handrail?
Well-designed steps do not need to represent a safety hazard, but there are some basic considerations. A single step is dangerous if people fail to see the change in level.Balustrades and handrails are not a legal obligation for garden steps, but may well help anyone unsure of their footing.

Do space saver stairs comply with building regulations?

Do spiral staircases meet building regulations?

Should garden steps have an overhang?
Use of overhanging nosing of 15 – 25mm is especially useful for short treads of 300mm or less. This helps to prevent stubbing one’s toe against the riser. Any more than 25mm and the overhang of the tread above may become a tripping hazard. The Building Regulations Part M advocates rounded nosings to minimise tripping.
What is a comfortable step height?
Rule one says that rise plus run (r+R) should equal 18 inches. Why? That’s what most people find to be a comfortable stride on most stairs. You can cheat a bit up or down, but below 17” and more than 19” will result in steps that require strides either too big or too small for most people.
Should outdoor steps be level?
For outdoor stairways, treads must be slightly sloped so water will not accumulate on the stairs. Install a 1% slope (1/8 inch per foot) to ensure water runoff but do not exceed the maximum allowable slope of 2% (1/4 inch per foot) in any direction.
Is an 8 inch step too high?
Building codes in many areas define maximum step height and minimum tread width, but in areas where it is not defined, Council of American Building Officials and International Code Council both recommend the rise to be no more than 7.75 inches and runs to be no less than 10 inches.
How do you calculate garden steps?
To work out how many risers you need, divide the vertical height of the flight by the height of your riser. Then divide the horizontal length of the flight into a suitable number of treads. The combinations of tread and riser measurements in the table will make attractive, safe steps.
Do you need planning permission for a staircase?
Nearly all internal works such as loft conversions, garage conversions, new staircases, bathrooms, kitchens, or rewiring, do not require planning permission.
What is the minimum space required for a staircase?

What is the maximum rise for a step?
(1) The rise of every step in a stairway shall be not less than 4 inches nor greater than 7 1/2 inches. (2) The run shall not be less than 10 inches as measured horizontally between the vertical planes of the furthermost projection of adjacent treads.
