Code expert Glenn Mathewson discusses the landing requirements for exterior doors, including threshold dimensions, allowable steps from the threshold down to the landing, and the most common door thickness between 44mm and 58mm. Thresholds at these doors, including sliding door tracks, should not be higher than 1 1/2 inches (38 mm) above interior floor level. An exception permits the exterior landing of an exterior egress door to be a maximum of 7 3/4 inches. The landing on both sides of an egress door must be at least as wide as the door it serves, extend at least 3-feet perpendicular to the door, and not be more than 1 inch in height.
To ensure weatherproofness, the correct door must be fitted correctly. This can be done by adding a new ¾-inch-thick oak threshold on top of the old one, trimming the door slightly, and installing a new door sweep. Thresholds are limited to 1/2″ in new construction, with an edge beveled 1:2 maximum above a height of 1/4″. Existing or altered thresholds may have a maximum height of 3/4″ if they have a beveled edge on each side with a slope not steeper than 1:2.
Thresholds at doorways should not exceed 3/4 inch (19.1 mm) in height above the finished floor or landing for sliding doors serving dwelling units. Based on the threshold requirement exceptions, the threshold can be max. 3/4″ with a 1:2 bevel for sliding exterior doors. 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.
ADA compliance is no more than 3/4″ high, but information on this requirement is not available in the MA building code. The minimum is 1.5″ step down with no more than 7 3/4″ step down from the threshold.
📹 How to Adjust the Threshold to an Exterior Door
If there is a gap under your door, you may need to make adjustments to the threshold or replace the sweep. In this JELD-WEN …
What is a safe threshold height?
The ADA guidelines for threshold height and thickness include not exceeding 3/4 inch for exterior sliding doors or 1/2 inch for other types of doors. Level changes up to 1/4 inch can be vertical and do not require edge treatment. Level changes between 1/4 inch and 1/2 inch must have a beveled slope equaling 1:2. Standard thicknesses for 4″ and wider thresholds are 5/8″ and 3/8″ or 1/2″ for 2″ wide thresholds. Hollywood thresholds have large ramps like 1 3/8″ bevels.
Where should a door threshold sit?
In the event that a T-bar is to be installed in a doorway devoid of a door, it is recommended that the expansion gap be positioned in the center of the doorway frame. In the event that a door is present, the gap should be positioned beneath the closed door in order to ensure an appropriate fit. It is then necessary to measure the width of the doorway and mark the positions for the track and T-section cuts. The T-bar should be cut using a sharp saw, with care taken to ensure that the cut is made outside the line. Should any rough edges remain, these can be sanded down as required.
What is the threshold requirement?
The Predevelopment Loan Program has several requirements for applicants. The threshold requirements are identified in the Application Package, while the minimum requirements for commercial structures are available at portlandgeneral. com/energy-choices/renewable-power/green-future-impact. These requirements may be updated to reflect PGE’s criteria from its latest Commission accepted renewable request for proposals. OHS requirements refer to all laws and city policies related to occupational health or safety, including the World Health Organization (WCA).
MREL requirements refer to laws, regulations, guidelines, rules, standards, and policies relating to minimum requirements for own funds and eligible liabilities applicable to the Issuer and/or the Group. These requirements may include delegated or implementing acts adopted by the European Commission, regulations adopted by the Federal Republic of Germany or Italy, a relevant resolution authority, or the European Banking Authority. These requirements may be amended, supplemented, superseded, or replaced from time to time.
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.
How do you measure exterior door threshold?
In order to guarantee an optimal fit, it is recommended to utilise the existing threshold as a template, or alternatively, employ a distinct threshold if one is not available.
What is the threshold standard?
A threshold standard for solicitors is a set of competencies that requires a deep understanding of their practice area and a broad background awareness of legal principles. This standard is required at the point of qualification, with level three being the minimum required. The standard is routinely achieved and takes full responsibility for progressing cases or transactions. The competence statement is generic and applies to all solicitors, with other levels provided for context.
What is the maximum height for a threshold without a beveled edge in a doorway?
Thresholds in new construction are limited to 1/2″ height, with a 1:2 beveled edge above 1/4″. Existing or altered thresholds can reach a maximum height of 3/4″ if they have a beveled edge on each side with a slope not steeper than 1:2. The ADAStandards outline scoping and technical requirements for accessible entrances, doors, and gates. At least 60 public entrances must be accessible in new construction, including those serving tenancies, parking facilities, pedestrian tunnels, and elevated walkways. “Public entrances” include all entrances except those restricted or used exclusively as service entrances.
How high should an exterior door threshold be?
The threshold should be 1/2-3/4″ higher than the interior flooring to allow the door to clear the flooring but not block the passage. We build thresholds from 3/4″ to 1 3/4″ high. Wood thresholds can be refinished quickly and last for decades if cared for properly. They are built flush with the jamb legs on both interior and exterior surfaces. It is recommended to install the prehung unit over a sill nosing or flashing to divert water to the exterior over the foundation.
How high can an interior threshold be?
It is imperative that doorways do not exceed a height of 3/4 inch (19. 1 mm) for sliding doors in dwelling units or 1/2 inch (12. 7 mm) for other doors.
What is the standard size of a threshold?
Thresholds are essential in doorways, serving as water barriers and smoothing out the junction between carpet and tile. They are typically 1 to 2 inches longer than the door, with popular sizes being 24″, 36″, and 42″. StoneXchange, a manufacturer, importer, and distributor of marble stone threshold strips, offers clients the opportunity to purchase standard and non-standard size thresholds in bulk supply at the lowest wholesale prices. Thresholds can be placed in a doorway, such as a bedroom covered in carpet, at the bathroom entrance surfaced with marble tile.
What is the standard door threshold?
Door thresholds are typically 1/2″ or 1/4″ tall, as per ADA guidelines. Commercial applications typically have heights of 1/4″, 1/2″, or 3/4″. However, residential applications may not follow these guidelines. Threshold height can vary between types, such as bumper seal thresholds, which are 1/2″ up to 1″ tall due to their construction. Offset thresholds are also taller than average thresholds, as they span two different height surfaces.
To extend a commercial threshold, you must remove the current threshold and replace it with a new one that fits the desired wider dimension. Thresholds are extruded and standalone items, so they cannot be combined without compromising their integrity and ratings.
Does a door need a threshold? While doors are not required, they serve various purposes, such as increasing the rigidity of the door and frame, and creating a weatherproof seal with a sweep. Thresholds are not required for doors, but they can serve various purposes, such as increasing the rigidity of the door and frame, and providing a weatherproof seal from the outside elements.

Yes, great work. I debate the time element. Going to the store, getting the exact materials, i.e. stain., setting up tools, breaking down tools,etc. And the whole misleading statement in the section below the article about equipment and materials particularly the track saw. Cannot buy that at the Home Depot or Lowe’s. That is the Festool. The saw and track guide I am guessing is minimum $800.00 and suppose to be used with their vac system.
Tom teach them how to do this with scrap plywood utility knife circular saw and not a 756 dollar track saw. so other people know Im a 50 plus year shop teacher, I love this old house and you have many important items. but think of the needs of the people. they just shut down when they see the price tag on your donated equipment.
NICE SAW SETUP BUT AN EXPENSIVE OVERKILL unless you use one everyday for a living. The saw in this article will set you back around $400. A standard circular saw (which many of you already have) and a straight edge clamped to the door will work just as well. First cut half way through the door then flip the door over and make the second cut the other half way through. This should give you a smooth finish on both sides. Use a metal cutting blade if your door is metal clad like most exterior doors have to be by code requirements except this one!
The homeowners want the rug, so that lets that out of the program. Nice to be able to cut the bottom of the door off when you have a thousand dollar tool to do the job. Me… I’ve used a piece of plywood – clamped to the door – for a straightedge many times. Yeah… you’ve got to build that threshold up. Use a plain old seal on the bottom of the door. Those things that retract into the door bottom are nothing but an all-around pain in the butt.
I was at place today that had a similar modification, they do have a sign to warn you of the extra bump. Looks beautiful but it is a tripping point. I can imagine though some type of fairly simple system that would allow for a seal to drop down and lift up during door operations. This idea is absolutely doable lets just hope the inventor keeps the price in check. Could and should be worked to be an internal component and optional external component. I can see people heading for the drawing board or CAD program.
Anyone know how to reverse a door from swinging into a room to swinging outwards? I can’t seem to find any articles or website which shows this. Probably because I am using incorrect terminology 😛. Reason: My small laundry room cannot swing inwards because the door hits the dryer. I had to remove the door but I would like the door to swing outwards.
If you are perusal this article to learn how to do something for yourself make sure you don’t use a chisel like this apparent professional buy it in your palm of your hand against the back of the chisel you damage nerves in your hand that’s why you should never do that use a mallet that’s what they are for or a Sharpie chisel and push
