How Large Of An Outside Door Landing Must It Be?

Glenn Mathewson, a code expert, discusses the requirements for exterior door landings, including threshold dimensions, allowable steps from the threshold down to the landing, and step-down requirements. Landings must be constructed on both the exterior and interior side of the door, with a width of at least 36 inches (914 mm). There should be a landing or floor on each side of each exterior door, and the width of each landing should not be less than the door served.

The Second Exception in Section R311.4.3 allows a landing to be placed a maximum of 7-3/4 inches below the top of the threshold at any door. Exterior landings of impervious construction (e.g., concrete, brick, flagstone) serving primary entry doors and required exit doors are limited to not more than 1 / 2 inch (12.7 mm) of length.

The International Building Code states that a flight of stairs shall not have a vertical rise greater than 151 inches (3835 mm) between floors or landings. Landings must be the same width as the door they serve and have a dimension of not less than 36 inches (914 mm).

Alternating doorways must have a landing at least 7¾ inches (196 mm) below the top of the threshold, provided the door is not an egress door. Landings should be at the same height as the floor inside, and a “step down” is required to reach the landing. Landings or finished floors at the required egress door must be no more than 11/2 inches (38 mm) lower than the top of the threshold.

How big does a landing need to be at an exterior door?

It is a requirement that each exterior door is provided with a landing or floor on each side. The width of each landing must be not less than that of the door served, and a dimension of at least 36 inches (914 mm) must be provided in the direction of travel.

What is an exterior door threshold?

An exterior door threshold is a section of your doorway that provides an air-tight fit between your floor and the door’s bottom. It is crucial for ensuring your home is weatherproof and prevents draught from entering. There are various types of exterior door thresholds available in various styles and options. Whether you’re building a new home or renovating an existing one, ensuring your front door threshold is adequately fitted is essential for finding the perfect door, insulating your home, and achieving your desired style.

What is the minimum landing between stairs?

The landing distance in front of the top and bottom step must be at least the width of the staircase, as per The Building Regulations 2010 Approved Document Part K1 – Stairs, ladders and ramps 2013 edition for use in England. The most important dimension for any stair manufacturer is the distance from finished floor to finished floor, as this information is only intended as a generic guide and should be checked with a local building professional.

What is landing width?

Stairs must have landings that are at least as big in length and width as the flight’s width, and must comply with minimum widths for the staircase type. Landings should be kept clear of permanent doors in England and Wales, provided they are kept shut and provide a minimum clear space of at least 400mm deep. In Scotland, this is only allowed on private staircases within homes. Landings should be level and have a gradient of 1:60, meaning for every 1 unit of rise or fall, there should be 60 units of landing, more likely to occur in external situations.

What is the standard dimension for stair landing?

Stair landings are crucial for creating a safe and secure staircase experience. They should be at least as wide as the stairway and 36 inches deep to provide enough space for safe movement. Carpet stair treads and carpet landings can enhance the comfort and style of stairs. The rule for stairs landing states that landings must be at least 36 inches deep and wide enough to allow for safe stopping, turning, and turning. They are required at the top and bottom of every staircase and must be level to prevent tripping.

How wide should landing be?

The text outlines the requirements for stairway landings, which must be at the top and bottom of each stairway. The width of landings must be equal to the width of the stairways served, and every landing must have a minimum depth equal to the stairway’s width or 48 inches (1219 mm). Doors opening onto a landing must not reduce the landing to less than half the required width, and doors must not project more than 7 inches into the required width. If wheelchair spaces are required, they must not be located in the required width of the landing and doors should not swing over them.

Stairway landings are not required at the transition between stairways and stepped aisles, and the landing depth should be measured horizontally between the intersection of the lower flight’s walkline and the upper flight’s walkline. If a landing turns 90 degrees or more, the minimum depth is not required if the landing is not less than that described by an arc with a radius equal to the flight’s width.

What is the height of a threshold on a front door?

Thresholds are made of metal with varying thicknesses and heights, with ADA requirements limiting height to 1/2″ and incline to 1/4″. They can be supplied in widths from 2″ to 10″. Custom thresholds can be ordered to match or exceed frame jamb depth. Heavy duty thresholds are recommended for use with forklifts or vehicles, as they last longer and are made of thicker metal. These thresholds can resemble saddle thresholds or even include bumper seals.

Do exterior doors require a threshold?

An accessible route aims to maintain a continuous path of travel without abrupt changes in level, enabling people with disabilities, wheelchairs, scooters, and walkers to move without impeded. However, changes in level are inevitable at exterior doors due to thresholds and water infiltration. Guidelines allow limited changes in levels at exterior doors along accessible routes, with thresholds at these doors no higher than 3/4 inch and changes in level beveled with a slope no greater than 1:2. Primary entry doors with impervious exterior landing surfaces can have an overall change in level of 1-1/4 inch on the exterior side of the primary entry door.

What is the minimum space for a landing?

Building control is a crucial aspect of any building project, requiring approval from the local authority (LABC) for various types of work such as loft conversions, garage conversions, extensions, conservatories, electrical work, internal alterations, basements, and porches. The length of the landing should be at least as long as the stair or ramp is wide, with no width recommendation given for stairs or ramps in dwellings.

The building control process works by requiring an Approved Inspector’s insurance to be renewed, and the cost of building control applications varies. If an Approved Inspector’s insurance has expired, they must transfer work from an AI that no longer has insurance to an LABC team. The project must then be reverted to the local authority, and the cost of canceling an initial notice and reverting work to the local council is calculated.

Approved Inspectors can continue without the required insurance, but there are exceptions. A cancellation notice must be issued by the Approved Inspector when reverting a project to the local council. If an Approved Inspector fails to secure renewal of their insurance, a cancellation notice must be issued. Information should be requested from the Approved Inspector when reverting a project to the local council.

The Government and LABC are working to help in this situation, providing further information and updates on building regulations. They also offer assistance to those who do not have the right permission for building work and can appeal enforcement notices.

How tall is the rough opening on an exterior door?

In order to ascertain the approximate dimensions of an opening for a new door, it is necessary to measure the width from the inside of the building, from stud to stud. This measurement should be taken at two or three different points along the width. It is imperative that the smallest dimension of the rough opening be recorded in order to guarantee that the new door will fit within the confines of the home.

The most commonly utilized rough opening widths are 38 inches. The dimensions are 5″ and 34. The height is 82 inches, and the width is 5 inches. The dimensions are 5″ and 98. The measurement is 5 inches.

What is the minimum exterior stair landing size?

In accordance with the relevant regulations, stairways and landings must be a minimum of 36″ in width. Handrails are required on at least one side of stairways with four or more risers, and must be continuous for the entire flight. Furthermore, the maximum slope permitted is 1/4″ per foot. The width of the landing area should be equivalent to that of the door.
