How to Test Accessible Doorways Before Handover

Sydney Access Consultants · Updated November 2026

A doorway can measure correctly on a drawing and still prevent a person from entering a room independently. A door leaf that opens into the wrong circulation zone, a closer set too strongly, or a threshold added late in construction can compromise access at the point of handover. Knowing how to test accessible doorways means checking the complete opening as it will be used, not simply measuring the frame.

For Australian projects, the relevant requirements will depend on the building classification, approval pathway, applicable edition of the NCC, referenced standards, and any access report or performance solution. AS 1428.1 is commonly central to the assessment of accessways and doorways, but site testing must always be undertaken against the requirements nominated for the specific project.

Start with the approved compliance pathway

Before attending site, establish what the doorway is required to achieve. Review the approved architectural drawings, door schedule, access consultant's advice, certification documentation and any approved variations. This avoids a common problem: a site team checking a door against a general rule while the approved design relies on a different arrangement or a performance-based solution.

Identify whether the doorway serves a principal pedestrian entrance, sanitary facility, circulation route, sole-occupancy unit, common area, accessible bedroom or specialist accommodation. A doorway on an accessible path of travel will often need assessment for more than clear width. Approach spaces, door swing, hardware location, threshold treatment, visual contrast and the force required to operate the door may all be relevant.

For refurbishment and heritage projects, constraints may affect the available solution. That does not remove the need for meaningful access. It means the assessment should clearly distinguish between what is technically constrained, what is reasonably achievable, and whether an alternative solution has been properly developed and approved.

Measure the clear opening, not the nominal door size

A 920 mm door leaf does not automatically deliver a compliant clear opening. The relevant measurement is generally taken with the door opened to the required position, between the face of the open door leaf and the opposing stop or frame. Door stops, seals, panic hardware and the geometry of the leaf can all reduce the usable width.

Use a calibrated tape measure or laser measure, and record the result at the narrowest point. Take photographs that show the door in its measured open position and include a reference point where practical. If a door has a hold-open device, test the opening as it would operate in normal use rather than assuming the leaf will always stay fully open.

Clear opening width is only one part of the test. A wide opening is of limited value if a person using a wheelchair cannot approach the door, position themselves beside the latch, operate the hardware and move through without being struck by the leaf. This is why doorways should be tested as a sequence of movement.

Check approach and circulation spaces

Assess the circulation space on both sides of the door, including areas beside the latch side and within the path of the opening leaf. Confirm that joinery, furniture, fire equipment, bollards, planters or temporary operational items have not been placed within spaces needed for access.

Door swings require particular attention. A door that opens towards a person may force them to reverse out of the way after operating the handle. In a small room, such as an accessible sanitary facility, the door swing can also conflict with the required circulation area, fittings or emergency assistance arrangements.

Where doors are adjacent to corridors, ramps or landings, consider whether the opening leaf intrudes into the route of travel. The design may have met dimensional requirements when documented, but changes to wall linings, skirtings, door furniture or floor finishes can reduce the space available on site.

Test thresholds as part of the route of travel

Thresholds are a frequent source of last-minute non-compliance. Check the finished condition, not the condition before carpet, tile trims, weather seals or drainage components are installed. Use a straightedge and level where necessary to identify abrupt changes in level, raised edges or poorly detailed transitions.

The applicable requirements may limit threshold height and specify how a change in level is to be treated. The key functional question is whether a wheelchair, mobility aid, pram or person with reduced balance can pass through without a jolt, trip hazard or excessive effort. External doors deserve extra scrutiny because weatherproofing, drainage and bushfire provisions can lead to threshold details that conflict with accessible movement.

Where a compliant flush transition cannot be achieved through standard detailing, the project team may need a coordinated solution involving the architect, access consultant, hydraulic engineer, builder and certifier. Adding a small ramp without checking gradients, drainage and door clearances can create a different compliance issue.

Operate the door as a user would

A doorway is not accessible if the hardware is difficult to grasp, positioned poorly, obstructed by a door stop, or requires excessive force to operate. Test every relevant component: lever handle, pull handle, lock, latch, closer, automatic operator, magnetic hold-open and access-control device.

Use a door force gauge where the project requirements call for a maximum opening force or where the door feels difficult to operate. Test from the side and direction in which a user would normally enter. The force required to unlatch a door may differ from the force needed to move it through its arc, particularly where closers, seals or pressure differentials are involved.

Fire doors often present a practical trade-off. They must satisfy fire safety requirements while remaining operable by people with disability. Do not adjust closers casually to reduce opening force. Any changes must preserve the fire door's tested performance and be coordinated with the relevant fire, building and certification requirements.

For powered doors, confirm that activation controls are reachable, visible, logically located and usable without standing in the door swing. Check the opening time, closing time, detection zones and behaviour when a person moves slowly through the doorway. Automatic doors should not close prematurely on a person using a walking frame, wheelchair or mobility scooter.

Inspect hardware, contrast and glazing

Hardware should be easy to identify and operate. Lever handles are generally more usable than round knobs for people with limited grip strength or dexterity, but the correct selection depends on the applicable project requirements. Check that handles do not clash with adjacent walls, cabinets or security hardware and that the latch-side clearance allows an approach to the handle.

Visual contrast can assist people with low vision to locate door hardware and distinguish the door from surrounding surfaces. This is particularly relevant in public buildings, education settings, aged care facilities and common areas. Contrast should be assessed under the installed lighting conditions, not only from a finish board in a design meeting.

Where doors contain glazing, assess whether the glass is apparent to people moving through the space. Manifestation, framing and contrast treatments may be needed, depending on the application and relevant standard. Also check that glazing is not obscured by signage installed after construction.

Use a repeatable site-testing method

A defensible inspection records what was tested, how it was tested, the applicable reference and the resulting action. For each doorway, document the location, door type, clear opening, threshold condition, swing direction, approach spaces, hardware, operational force and any observed obstruction. Photographs should be clear enough for a contractor or superintendent to identify the issue without returning to site.

It is sensible to test representative doors early, before the same error is repeated across dozens of rooms. In apartment developments, aged care projects, schools and health facilities, a single incorrect door detail can become a costly programme-wide rectification. A mock-up review or early-stage site inspection gives the project team an opportunity to correct procurement and installation issues before finishes are complete.

Where a discrepancy is found, avoid vague directions such as “make accessible”. State the issue, identify the relevant requirement, explain the functional impact and nominate a practical rectification pathway. Sometimes the answer is a minor adjustment to a closer or door stop. In other cases, the frame location, door leaf width, threshold detail or room layout must change.

Treat handover as the beginning of operational access

Final testing should reflect how the building will operate after occupation. Security settings, furniture layouts, access-control protocols and maintenance practices can all undermine an otherwise compliant doorway. Facility managers should understand which doors must remain available, how automatic operators are maintained, and why obstructions at latch sides or in circulation zones create an access barrier.

Accessible doorways are not a finishing detail. They are a practical condition of independent entry, exit and participation. A careful on-site test before handover protects compliance, reduces rectification risk and, most importantly, helps ensure the building works for the people who rely on it every day.
