Webinar Session Details

Common Sources of Confusion

Thursday, September 1, 2022
2:30 PM - 4:00 PM Eastern Time Zone


Certain provisions in the ADA and ABA Accessibility Standards are prone to misinterpretation and generate many of the technical assistance inquiries the Access Board receives. This webinar will review and clarify common sources of confusion in the standards, including application of the standards in new construction and alterations, electric vehicle (EV) charging stations, toilet rooms, signs, accessible routes and ground surfaces, and other areas and elements. Session participants are encouraged to share their own areas of confusion and submit questions in advance of the session. This webinar will include video remote interpreting (VRI) and real-time captioning. Questions can be submitted in advance of the session or can be posed during the live webinar. Webinar attendees can earn continuing education credits.

Questions for presenters:

1 For EV parking spaces, since they're located within the ROW do they follow the PROWAG guidelines or the ADA onsite standards or both have the same language?
2 I work for a parks provider that does not receive federal money nor is federally operated. The ADA does not have specific guidance on natural surface trails, camp sites, picnic areas, campgrounds, beach access, etc. The ABA does have specific guidance on all of those programs. If we're not held to ABA standards, how do we best go about making our natural areas accessible?
3 Please address the application of the 2010 ADA Standards for Accessible Design as they may apply to State/U.S. Military National Guard facilities. Clearly, most areas of such facilities require "Able-bodied" personnel involved in combat training and equipment maintenance. I can see where "administrative" support personnel would likely require accommodations, but the remainder of such facilities would not require accommodation. Thank you for considering this issue.
4 2010 ADA does not show how to measure the tread run on steps covered by the ADA. IBC and the old ANSI A117.1 says from nose to nose. Which mean if the riser is sloped that over lap is not counted as a part of the tread depth. Please tell us how ADA 2010 measures tread run depth?
5 In alterations to make an existing building entrance comply with the ADA and I am stuck about not making the handrail extend on the entry door wall side, is it more important to have an ADA 100% compliant ramp or to make a shorter steeper ramp to accommodate the 12” handrail extensions. I am constrained by existing utilities at the bottom of the proposed ramp. If I can eliminate the handrail extension on the side nearest to the edge of the main entry doors (only one of the four extensions will be affected) can I do this? By doing so I can make the ramp in 100% ADA compliance.
6 Does the ADA allow diagonally attached landings at the top and bottom of ramps? Is there anything specific about approaching a ramp perpendicularly? I could not find anything that said the curb ramp or ramp landing has to be perpendicular to the path of travel.
7 409.2 curb or barrier. There is no stated height for a raised solid curb. Since the heights of edge protectors in this section only applies only to pipe or intermediate railings, does the illustration figure 405.9.2 apply to the heights of raised curbs. Does this illustration imply that that a raised solid curb such as concrete, asphalt, or wood, needs to be 4" plus the diameter of the pipe (~6" high)?
8 505.6 Gripping Surface - states that: Handrail gripping surfaces shall be continuous along their length and shall not be obstructed along their tops or sides. The bottoms of handrail gripping surfaces shall not be obstructed for more than 20 percent of their length. Where provided, horizontal projections shall occur 1½ (38 mm) minimum below the bottom of the handrail gripping surface. Can i have sections that are continuously obstructed for 20% of each run of railing? If my railing is 25 feet long can 5 feet of it be continuously obstructed and not a grippable surface?
9 Door and bathroom fixture clearances and which are able to overlap, in both multi-user and single-user toilet rooms, can get very tricky in existing buildings. We have also run into confusion on "dead ends" in multiuser bathrooms where someone may have a clear path to enter but not turn around easily to the accessories such as paper towels, trash, or to exit the bathroom. Similar to question 5 above, in an existing building, which is the most important requirement. Thanks.
10 Kitchen work surface one required 30” wide by 34” high AFF 804.3. This one required work surface in a kitchen or kitchenette, requires a forward approach or removable cabinet, is this correct?
11 Are all outlets in a kitchen or kitchenette required to comply with 205.1? Since standard kitchen counters are all 36" high above the finished floor does that mean the requirement under 804.3 for only requiring one 34" high by 30" wide, work surface does not apply and that all work surfaces in a kitchen with an outlet on the wall would have to be 34" high?
12 804.5 for kitchens says that at least 50% of shelf space in storage facilities shall comply with 811. For purposes of compliance with 804.5, has the Dept. of Justice determined whether drawers in kitchen cabinets are considered a type of shelf space? And if the answer is "yes", then is the allowable reach range height determined by (a) the upper surface of the drawer bottom, (b) the location of the drawer handle, and/or (c) the topmost edge of the drawer face?
13 Can you elaborate any on what level of UFAS compliance is expected for a renovated space that has spatial limitations? For instance, we’ve been told the 0" threshold shower transition requirement was permitted to be a normal ADA 1/2" in a renovation. Is there some document that explains these types of compliance items?
14 Does the ADA or PROWAG allow for truncated dome tiles to be cut to form an arc/radius on a curb ramp? For example, cutting rectangular dome tiles into trapezoids to custom fit around a radius but in doing so the domes themselves are cut (no longer full dots) along all the tile edges and leading to partial and full domes/dots not meeting spacing requirements at the tile joints.
15 The new ASME A17.1-2019 2.27.2 Elevator Code requirement for audible and visual emergency communications is being implemented and there is not clarity on the height of the visual screen location, nor the size of the text. Elevator companies are attempting to apply ATM/Fare machine requirements, but not addressing visibility from 40 inches AFF. The operable parts are being clearly implemented and keeping buttons at 48 inches maximum. Guidance is needed for the visual screen location and the the text size in the screen.
16 Our Federal agency is in a facility that was built within the past 5-years buy a non-Federal company, and we lease the building through GSA. There is not a passenger drop-off/pick-up area beyond a bus stop that does not have an accessible curb-cut. There is an accessible curb-cut at the end of the block requiring the vehicle to block the crosswalk and possibly protrude into the intersection. We have been told that ABA does not apply because the county where the building is located does not require a drop-off/pick-up area.
17 When looking as the accessibility of the path of travel from on street parking to a Federal agency, what are the requirements for: 1. Accessible parking spaces dedicated to visitor parking for the Federal agency leasing the building; and 2. Accessibility of inclines along sidewalks bordering the street and the facility property leading to the accessible path to the building?
18 My questions seemed to be deleted from the above list. Aren't they on a first come first serve basis? Will this reduce the chances of my questions being answered? There were only three other questions when I posted. There are a lot of folks out here watching to see what the answers are.
19 Are there requirements for elevator call buttons to: 1. have tactile markings to indicate up/down; and 2. provide any type of audible indicator that the button has been activated? If there is no requirement for one or both of these conditions, what is the justification for not having such a requirement?
20 Is there a requirement that garage parking spaces for electric charging stations take priority to be located closest to elevators and pedestrian accessible entrance/exit, or do accessible parking spaces still adhere to the ABA requirements?
21 Is there someone I can call who will provide more resources and staff to the US Access Board to help provide colleges with courses and trades with specific training on disability design and constructed ergonomics for wheelchair, mobility, vision, and hearing disabilities?
22 Our state DOT has interpreted commercial entrances "with yield or stop control" in PROWAG to be every commercial entrance because the DMV Driver's Manual requires vehicles entering a roadway yield or stop for traffic on the road, and not just commercial entrances with actual signs or signals. Is this the correct interpretation, or should detectable warning surfaces only be limited to specific commercial entrances?
