Guide to the ABA Accessibility Standards


This guide explains scoping and technical requirements for accessible entrances, doors and gates in the ABA Standards.

Accessible Entrances: Minimum Number


At least 60% of public entrances must be accessible in new construction, in addition to entrances directly serving tenancies, parking facilities, pedestrian tunnels and elevated walkways. “Public entrances” include all entrances except those that are restricted or that are used exclusively as service entrances.

Public Entrances Required to be Accessible

Buildings with connecting elevated walkway, separate tenancies, and parking garage.  Notes:  At least 60% of public entrances in addition to the other types of entrances required to comply. At least one entrance serving each direct access from parking structures.  At least one entrance from each elevated walkway or pedestrian tunnel.  At least one entrance to each tenancy in a facility.   Additional requirements apply to transit facilities and to entrances for inmates and detainees in judicial, detention, and correctional facilities.

Components of Accessible Entrances

Entrance with landing served by ramp and stairs.  Notes:  Communication Systems (§F230) Two-way communication systems, where provided, must be equipped with visual and audible signals and compliant as operable parts.  Designation (§F216.6) International Symbol of Accessibility label (not required if all public entrances are accessible).  Doors and Doorways (§F206.5.1) At least one compliant door or doorway.  Accessible Route (§F206.3) Accessible route to entrance from site arrival points and located in the same area as general circulation paths. Security Barriers (§F206.8) Bollards and other security barriers cannot obstruct accessible routes.  Detail - Access symbol with directional sign and note:  Directional Signs at Inaccessible Entrances (§F216.6) Signs indicating the location of the nearest accessible entrances are required at each inaccessible public entrance.  These signs must include the International Symbol of Accessibility and note direction.  Additional content or text is not specified, but can be helpful.  It is advisable to locate signs in a manner that minimizes back-tracking.

Entrance Landings

Entrance landings must accommodate door maneuvering clearances as well as landings for provided ramps.

Recommendation:  Configure landings so that maneuvering at ramps and doors does not occur near stair openings and open drop-offs.  Recommendation:  Locate door swing outside ramp landing for greater safety.

Security Barriers


Security bollards and screening devices at accessible entrances cannot obstruct accessible routes or accessible means of egress. Accessible routes can be adjacent to metal detectors and other screening devices that do not accommodate all people with disabilities, but the route must be located so users can maintain an equivalent level of visual contact with personal items.

Restricted Entrances


If entrances are restricted to certain occupants on a controlled basis, at least one must comply in addition to public entrances required to be accessible. This applies to those entrances where entry access is verified by security personnel and is strictly limited to certain occupants, but no one else, including guests or companions of authorized individuals. All other types of entrances, excluding service entrances, are considered “public entrances” under the Standards, including employee-only entrances requiring keys or access cards or codes but that lack the level of security of restricted entrances.

Two-way communication system at entrance

Two-Way Communication Systems


Where two-way communication systems are provided to gain entry to a facility or to restricted spaces, they must include visual and audible signals to accommodate people with hearing, speech, or visual impairments. This applies to all entrances equipped with such systems, including those that are inaccessible. Lighted signals should have labels to indicate their meaning. If handsets are provided, cords must be at least 29” long. Control buttons and other operable parts must comply at those systems located at accessible entrances.


[§F206.4 and §F202.4]

In alterations to existing facilities, accessible entrances are required:

  • if an existing entrance is altered (and no fully compliant entrance already exists);
  • when entrances are newly added to a facility or as part of a facility addition; or
  • as necessary to achieve an accessible path of travel to primary function areas that are altered (unless disproportionate to the cost).

When alterations are made to primary function areas, a connecting accessible path of travel from site arrival points is required to the extent that it does not exceed more than 20% of the project cost. Achieving an accessible entrance should be the top priority in providing the accessible path of travel according to regulations implementing these Standards.

Qualified Historic Facilities

These requirements also apply when alterations are made to qualified historic facilities. However, if making a public entrance accessible would threaten or destroy a facility’s historic significance (as determined by the appropriate State Historic Preservation Official or Advisory Council on Historic Preservation), access can be provided to a non-public entrance instead. A notification or remote monitoring system is required where such an entrance is locked. (§F206.4, Ex. 2)

Doors, Doorways and Gates

[§F206.5 and §404]

Compliance is required for doors, doorways, and gates providing user passage on accessible routes. At least one accessible door, doorway, or gate serving each accessible room, space, and entrance must comply.

Manual Doors and Gates


Door with hardware 34” – 48” high measured to operable portions, a vision panel 43” max. above the floor measured the bottom edge, and smooth surface on the bottom of the push side 10” high min. extending full width of door.  Notes:  Closing Speed (§404.2.8) Closers: 5 sec. min.  from 90 degrees to 12 degrees (spring hinges: 1.5 sec. min. from 70⁰ to 0⁰), Opening Force (§404.2.9)  5 lbf max. (excluding exterior hinged doors and fire doors), Vision/ Side Lights (if provided) (§404.2.11) , Accessible viewing height 43” max. unless not intended for viewing       (i.e., lowest part above 66”), Hardware (§404.2.7) Operable parts must comply, Smooth Surface (§404.2.10) Required at the bottom on the push side, Thresholds (§404.2.5) 1/2” max. high (beveled if above 1/4”), Maneuvering Clearance (§404.2.4) required on both sides (unless door or gate is used in one direction only), Double-Leaf Doors (§404.2.2) One active leaf of double-leaf doors is required to meet criteria for clear width and maneuvering clearance.  Other door requirements apply to both leaves.

Clear Width


Clear width 32” min. shown measured from the stop to the face of the door open 90 degrees

The clear width is measured from the stop to the face of doors or gates open 90⁰ (or to the leading edge of sliding or folding doors. No projection into the clear width is permitted below 34.”

Clear Width and Vertical Clearance of Doors and Gates


Door opening with notes:  32 inch minimum clear width, (36 inch minimum if doorway deeper than 24 inches).  In alterations: latch side stop can reduce the clear width five-etights inch maximum vertical clearance.   Height 80 inches minimum (78 inches minimimm at door closers and stops.  Between 34 inches and 80 height, 4 inch maximum projection into clear opening widteh permitted on both sides.  Below 34 inch height, no projections into required clear opening width

Maneuvering Clearances


Required maneuvering clearances provide space for opening and proceeding through doors, doorways, and gates using wheelchairs and other mobility aids.

Maneuvering clearances are specified according to direction of approach, swing of doors, and in some cases the presence of a closer or latch. They are required on both sides of doors or gates except at those that can be used in one direction only.

Hospital symbol ("H")

Clearance beyond the latch side is not required at entry doors to hospital patient rooms. Such doors are usually wider to accommodate beds and gurneys, and they are often located close to adjacent interior walls to facilitate circulation and to enhance privacy.

Recessed Doors and Gates


Door maneuvering clearance 8” max. from face of the door.  Note:  The maneuvering clearance is measured from the wall but cannot be offset more than 8” from the face of the door.

Thick walls, casework, shelving, columns and other elements can cause doors or gates to be recessed. If any obstruction within 18” of the latch side projects more than 8” from the face of a door or gate, maneuvering clearances for a forward approach must be provided. This space must be inset at obstructions so that it is no more than 8” from the face of the door or gate.

Door in shallow recess with maneuvering clearance 8 inches max from face of
door Walls and other obstructions can offset the maneuvering clearance up to 8" from the face of the door.
Door in deep recess over 8 inches deep with maneuvering clearance for
forward approach 8 inches max from face of the door At deeper recesses, the maneuvering clearance must be sized for a forward approach and located 8" maximum from the face of the door.



Threshold at door

The height of thresholds is limited to 1/2” in new construction. The edge must be beveled 1:2 maximum above a height of 1/4”. A maximum height of 3/4” is permitted for existing or altered thresholds if they have a beveled edge on each side with a slope not steeper than 1:2. These requirements apply to all types of doors required to comply, including sliding doors.

Threshold Profile

Threshold ¼” high max. with vertical sides.  Treshold ½” high max (3/4” max for existing/ altered thresholds) with vertical edge up to ¼” max and 1:2 max beveled edge above.  Note:  vertical edge must  be located below bevel, not above.

Doors and Gates in Series


At hinged or pivoted doors or gates in series, a separation is required that is at least 48” plus the width of doors or gates swinging into the space. This allows users to clear one door or gate before opening the next and applies to those doors or gates that are opposite each other where travel through both doors is required.

Recommendation: Wheelchair space 30” min. by 48” min. beyond the swing of a door in other configurations, such as vestibules with doors on adjacent walls, will provide room to clear one door before opening the next.

Door and Gate Hardware

Door and gate hardware must:

  • allow one-hand operation
  • not require tight grasping, pinching, or twisting of the wrist
  • operate with 5 lbf maximum
  • be located 34” to 48” above the floor or ground.

Hardware that can be operated with a loose grip or closed fist, such as lever-shaped handles and U-shaped pulls, accommodates the greatest range of users. (Closed-fist operation, while advisable, is not mandated by the Standards). Round door knobs do not comply because they require twisting of the wrist.

Latches and locks with small parts that must be manipulated can be difficult to use and will not comply if pinching is necessary. However, keys and access cards that are not part of the lockset are not required to comply (but those that do not require pinching or turning provide better access). Hardware that does not require simultaneous actions are better, but some types, such as handles with thumb latches are acceptable.

Opening Force


The maximum 5 lbf opening force applies to all accessible doors and gates except:

  • fire doors (minimum opening force allowed by code)
  • exterior hinged doors (no maximum specified)
  • latch bolts and other devices that keep doors or gates closed

The 5 lbf maximum applies to the continuous application of force necessary to fully open a door, not the initial force needed to overcome the door’s seal resulting from unequal pressure. Latch bolts must be retracted and other devices that keep doors or gates closed must be disengaged prior to measuring the opening force. (Such devices, like other door and gate hardware, must operate with a maximum 5 lbf force (§404.2.7), but their operating force is not included in the measure of door or gate opening force). Door pressure gauges and other products are available to measure the opening force.

Measuring Door or Gate Opening Force with Pressure Gauge

When using door gauges and other measuring devices, it is advisable to follow these steps (except where product instructions specify otherwise):

  • Open the door so that the face edge aligns with the door frame outside edge
  • Place gauge immediately above door operating hardware about 2½” from the latch edge of the door (approximately the centerline of the door hardware)
  • Push slowly keeping the pressure gauge perpendicular to the face of the door
  • Remove the pressure gauge when the door is open 70 degrees.

Opening Force of Exterior Doors

Person using power chair opening entrance door

The opening force of exterior swing doors is impacted by wind loading and other exterior conditions, gasketing, HVAC systems, energy efficiency, and the weight of doors. The minimum force needed to ensure proper closure and positive latch usually exceeds the accessible limit of 5 pounds of force (lbf) required at other doors. For this reason, a maximum opening force for exterior hinged doors is not specified in the Standards.

Door and Gate Surfaces


Detail of wheelchair user’s feet and footrests at open door with kickplate

The bottom surface of doors and gates on the push side must be smooth to a height of at least 10”. This facilitates access since mobility aids, including wheelchair footrests, are sometimes used to push or prop open doors. Kick plates can be used to help protect door surfaces, but any gaps or cavities between the kick plate and the door surface must be closed or capped. Horizontal or vertical joints in this surface cannot exceed a 1/16” variation in plane.

These requirements do not apply to:

  • Sliding doors
  • Doors and gates that do not extend to within 10” of the finish floor or ground
  • Existing doors or gates with kick plates (so long as cavities created by kick plates are capped)
  • Tempered glass doors without stiles if the top edge of the bottom rail or shoe is tapered at least 60⁰ from the horizontal.

Communication Access at Doors

[§806.3.2, §809.3.2.2]

In addition to requirements for two-way communication systems provided at restricted entrances, the Standards include requirements for communication access in transient lodging and residential facilities:

hotel and residential dwelling icons

  • visible signals for door bells or knocks are required in transient lodging guest rooms providing communication access (§806.3.2);
  • a hard-wired doorbell with visible signals is required at the primary entrance in dwelling units providing communication access, along with a means to visually identify visitors without opening the door, such as a vision panel or peephole (§809.5.5).

Doors and Gates Operated Only By Security Personnel

[§404.1, Ex]

Detention/correctional facility icon

Manual doors, doorways, and gates that are designed to be operated only by security personnel, such as guards in a jail or prison, are exempt from requirements for hardware, closing speed, and opening force, but must meet all other requirements, including those for maneuvering clearance. This exception applies only where security personnel have sole control of doors or gates. If automated, such doors or gates are required to comply only with provisions for clear width and thresholds, as well as applicable provisions of the referenced ANSI/BHMA Standards.

Automatic and Power-Assisted Doors and Gates


Label:  “Automatic Door – Caution”

Doors are not required to be automated, but must comply when provided. The Standards apply industry Standards developed under protocols of the American National Standards Institute (ANSI) and published by the Builders Hardware Manufacturers Association (BHMA). The ANSI/BHMA Standards address operating characteristics, including opening speed, safety features, sensors and activation devices, and labeling, among others. Doors are classified by their type or level of automation.

Power-Assisted Doors and Gates


Power-assisted devices reduce the opening force of doors with closing mechanisms.
They are activated by initial manual force, switches, or sensors. Most reduce, but do not fully eliminate, the manual force needed to open a door. For this reason, they must meet maneuvering clearance requirements.

Power-Assisted Door

Notes: Clear Width 32” min., Threshold 1/2” max. high (beveled if above 1/4”), Manual Controls must comply as operable parts if provided  , Maneuvering Clearance required, Doors in Series 48” min. separation required between the swing of doors in series, Industry Standard Compliance with the ANSI/BHMA A156.19 (1997 or 2002 edition)

Low Energy Doors and Gates


Low energy doors and gates usually require activation by the user through a push plate or control and are often used in moderate traffic locations as an alternative to manual operation. Most function like a manual type but with a powered opener and closer option.

Automated Door (Low Energy)

Low energy automated door.  Notes: Clear Width 32” min. (power on and off modes), Maneuvering Clearance is required at those doors serving an accessible means of egress that either lack standby power or that do not stay open in power-off mode, Threshold 1/2” max. high (beveled if above 1/4”), Manual Controls Compliant controls with clear floor space located outside door swing, Doors in Series 48” min. separation required between the swing of doors in series, Industry Standard Compliance with the ANSI/BHMA A156.19 (1997 or 2002 edition)



Door and gate controls must be compliant as operable parts (operable with one hand and without tight grasping, pinching, twisting of the wrist, or more than 5 lbf). Clear floor space at controls must be located outside the door swing to prevent users from getting hit by the door.

Full-Powered Automatic Doors and Gates


Full-powered automatic doors and gates are often found in grocery and retail stores, hotels, and airports to ease passage with shopping carts or luggage. Most are automatically activated by mats or overhead sensors and do not require manual activation by users.

(emergency mode) for doors on means of egress without standby power (unless a compliant manual swinging door also serves the same means of egress), Threshold 1/2” max. high (beveled if above 1/4”), Maneuvering Clearance is required at those doors serving an accessible means of egress that either lack standby power or that do not stay open in power-off mode, Industry Standard Compliance with the ANSI/BHMA A156.10 (1999), Doors in Series 48” min. separation between the swing of doors in series, Revolving Doors and Gates (§404.3.7), Manual revolving doors and gates and turnstiles are not accessible and cannot be part of accessible routes. Automated revolving doors, including those sized to facilitate access, do not meet the Standards. If they are provided at an accessible entrance, a compliant manual or automated door is also required.

Common Questions

question mark

Must a primary entrance be accessible?

The Standards require that primary entrances to dwelling units be accessible. It is advisable, though not required, that access be provided to the primary entrances of other types of facilities.

Is there a maximum travel distance to entrances from parking and other site arrival points?

No, the Standards do not limit the travel distance to accessible entrances. Accessible parking spaces must be located on the shortest accessible route to an accessible entrance (relative to other spaces in the parking facility). A quantitative travel distance between entrances and site arrival points is not specified. In addition, accessible routes must coincide with, or be located in the same area as, general circulation paths.

Is automation of doors required?

Automation of doors is not required by the ABA Standards, but it is highly recommended for entrance doors where the opening force is significant. (GSA’s Public Building Service Standards, which apply to GSA facilities but not to other federal facilities, require automation of exterior doors at accessible entrances.). A maximum opening force is not specified in the ABA Standards for exterior hinged doors because of the closing force typically necessary for ensuring positive latch against wind loading, air pressure, and other conditions. This often results in opening forces well above the 5 lbf maximum. Difficulty opening exterior swing doors is a common complaint. Automation offers the best solution. Otherwise, closers should be set with the minimum force practicable.

Do requirements for “public entrances” apply only to those entrances used by the public?

No, scoping provisions for accessible public entrances are not limited to those used by the public. The term “public entrance” applies to all entrances other than service or restricted entrances. “Restricted entrances” are those available for common use (but not public use) on a controlled basis. This is intended to apply specifically to entrances where user identity is verified and entry is strictly limited to certain occupants, but no one else, including guests or companions of authorized individuals. Other types of entrances with lower levels of security, including employee-only entrances requiring keys, keypads, or access cards, are considered “public entrances.”

Are employee entrances required to be accessible?

Where employee entrances meeting the definition of a “restricted entrance” are provided, at least one must be accessible. Other types of employee entrances must be accessible as “public entrances.” In facilities with separate visitor and employee entrances, access should be dispersed so that accessible entrances serve both types of traffic.

Are closet doors and pantry doors required to comply?

Requirements for doors, doorways, and gates in §404 apply to those that provide “user passage” (§F206.5). Doors serving walk-in closets or pantries must comply. Doors to shallow closets or pantries, cabinets and other storage elements not providing user passage do not have to comply with provisions for doors, but must meet requirements for storage (§811), including those for clear floor space and operable parts.

Is compliance on both sides of a door or gate required when it is usable only from one side?

No, compliance is not required on both sides of those doors or gates that can be used in one direction only. Compliance is required only on the usable side. Examples include exit-only doors with no operating hardware on the exterior side or separate enter and exit fare gates in transit stations. However, if a door or gate is usable in both directions, even occasionally, such as exit-only doors that may automatically unlock in emergencies to be usable from both directions, then compliance on both sides is required.

Can handrails or other elements overlap door maneuvering clearances?

No, door maneuvering clearances must be free of any overlapping objects, even those providing knee and toe clearance, which can interfere with maneuvering at doors and doorways. However, door maneuvering clearances can be offset up to 8” from the face of the door or gate to accommodate wall thickness, casework, shelves, or other elements adjacent to doorways, including handrails. The door maneuvering clearance must be measured from the leading edge of such elements so that the full clearance is free of any obstruction.

Is latch-side maneuvering clearance as specified in the Standards applicable to doors with panic bars?

When latch-side clearance is required as part of the maneuvering clearances specified for a door, including on the push side of doors with a forward approach that have both a closer and latch, it must be provided at manual doors with panic bars as well. Latch-side clearance not only provides proper positioning at door hardware but also facilitates proceeding through doors against the force of closers.

Are locks operated by keys prohibited due to the pinching or twisting of the wrist their operation typically requires?

No, non-fixed portions of door or gate hardware, including keys and access cards, are not covered by the Standards, but those that can be used without pinching or turning will provide easier access. Non-fixed portions can be modified or adapted as needed for accessibility.

Are spring hinges and gravity hinges considered “closers” in determining the size of maneuvering clearances?

No. Some approaches require additional maneuvering clearances when a door or gate is equipped with a closer because of the additional force that must be counteracted in proceeding through doors. Since spring and gravity hinges do not significantly impact the opening force of doors, they are not considered “closers” for purposes of specifying door maneuvering clearance.

Can maneuvering for a forward approach be provided when there is space at least 60” deep in front of a door?

Space at least 60” deep in front of a door that is unobstructed on approach sides will provide sufficient depth for a forward approach if appropriate strike-side clearance is provided; but in the case of pull-side/ hinge-side approaches, greater latch-side clearance (36” minimum) is still required because the minimum depth for this clearance is 60” (54” if the latch-side clearance is at least 42”).

and provides 36 inches min. strike-side clearance On the pull side of hinge approaches, 36” min. latch-side clearance is required if the depth is 60” min. (The depth can be 54” min. if the latch-side clearance is at least 42”.)

Is additional latch side clearance required on the push side of doors with a forward approach when either a latch or closer (but not both) is provided?

No, latch clearance 12” minimum is required for forward approaches on the push-side of doors equipped with both a closer and a latch. If a door has a closer but no latch, or a latch and no closer, no additional latch side clearance is required (although providing the clearance is helpful in maneuvering through doors with closers without latches). This is also true for the additional depth required for hinge approaches on the push side when both a closer and latch is provided. For latch approaches, additional clearance is required on the push side and the pull side when just a closer is provided.

Are screen doors or storm doors considered “doors in series”?

No, screen or storm doors are not considered “doors in series” since they are part of the same doorway opening as the entry door. They are not prohibited by the Standards but must meet all applicable requirements for doors except those pertaining to doors in series.

If a more recent edition of ANSI/BHMA Standards for automated doors is issued should that be followed instead of those referenced?

The specific editions of the ANSI/BHMA Standards referenced by the Standards are to be followed (although the Access Board intends to update references to keep them current). However, use of a later edition of the ANSI/BHMA Standards may provide equivalent or greater accessibility.
