ADA seating requirements: wheelchair spaces in assembly areas

In a theater, stadium, arena, auditorium or any other assembly area with fixed seats, the 2010 ADA Standards require wheelchair spaces, companion seats and designated aisle seats (2010 ADA Standards, 221.1 and 221.2). The number depends on the seats: one wheelchair space for 4 to 25 seats, 6 for 301 to 500, and more in larger venues (2010 ADA Standards, table 221.2.1.1). Each space is at least 36 inches (915 mm) wide (2010 ADA Standards, 802.1.2), has a companion seat beside it (2010 ADA Standards, 221.3 and 802.3.1), and offers choices of location and viewing angle substantially equivalent to, or better than, those of other spectators (2010 ADA Standards, 221.2.3). These are the numbers, the sizes and the rules for selling those seats, each with its section.

This is a summary. The official 2010 ADA Standards for Accessible Design are the reference.

How many wheelchair spaces

Minimum number of wheelchair spaces in assembly areas with fixed seating, from table 221.2.1.1 of the 2010 ADA Standards.
Number of seats Minimum wheelchair spaces
4 to 25 1
26 to 50 2
51 to 150 4
151 to 300 5
301 to 500 6
501 to 5000 6, plus 1 for each 150, or fraction thereof, between 501 through 5000
5001 and over 36, plus 1 for each 200, or fraction thereof, over 5000

The table applies to the seating in the assembly area (2010 ADA Standards, 221.2.1.1). Some parts are counted on their own:

  • Luxury boxes, club boxes and suites in arenas, stadiums and grandstands: each one follows the table, box by box and suite by suite (2010 ADA Standards, 221.2.1.2 and its advisory).
  • Other boxes, such as the tiered boxes of a concert hall, are counted together, using the total number of seats in them, and the wheelchair spaces go in at least 20 percent of the boxes (2010 ADA Standards, 221.2.1.3). The advisory note gives an example: 20 boxes of 10 seats each add up to 200 seats, which need 5 wheelchair spaces, placed in at least 4 of the boxes (2010 ADA Standards, advisory 221.2.1.3).
  • Team or player seating areas serving areas of sport activity have at least one wheelchair space of their own, except at bowling lanes not required to comply with 206.2.11 (2010 ADA Standards, 221.2.1.4).
  • Specialty seating areas that give spectators services or amenities not generally available to others also have wheelchair spaces and companion seats; if that is not readily achievable, the same services or amenities are offered at other accessible locations at no additional cost. These spaces count toward table 221.2.1.1, not on top of it (ADA Title III regulations, 28 CFR 36.308).

As arithmetic from the table, not a figure the Standards print: a 1,000-seat theater needs 6 spaces for the first 500 seats and 4 more for seats 501 to 1,000, which make three full groups of 150 and one fraction, so 10 in all. Each required space has at least one companion seat, so that is at least 10 companion seats too (2010 ADA Standards, 221.3).

The size of a wheelchair space

Size and position of a wheelchair space in an assembly area, in the 2010 ADA Standards.
Element Requirement Section
Width 36 inches (915 mm) minimum for a single space; where two spaces are side by side, 33 inches (840 mm) minimum each 2010 ADA Standards, 802.1.2
Depth, entered from the front or rear 48 inches (1220 mm) minimum 2010 ADA Standards, 802.1.3
Depth, entered only from the side 60 inches (1525 mm) minimum 2010 ADA Standards, 802.1.3
Floor firm, stable and slip resistant, with no changes in level; slopes not steeper than 1:48 are allowed 2010 ADA Standards, 802.1.1 and 302.1
Approach adjoins an accessible route, and the route does not overlap the space 2010 ADA Standards, 802.1.4
Circulation the space does not overlap circulation paths 2010 ADA Standards, 802.1.5

The advisory notes add two practical points. Because the route cannot overlap a wheelchair space, nobody should have to reach one wheelchair space through another (2010 ADA Standards, advisory 802.1.4). And the circulation path means the aisle width required by the building or life safety code: where an aisle is wider than that, a wheelchair space may take part of the extra width (2010 ADA Standards, advisory 802.1.5). Advisory notes explain the requirements but do not set enforceable requirements of their own (2010 ADA Standards, 28 CFR 36.406(b)).

A space for one wheelchair is not a gap left by removing a seat at random: it sits within the seating plan, at the width and depth above, next to its companion seat. Where spaces are paired, the Standards accept the narrower 33 inches each, so two adjacent spaces take at least 66 inches (2010 ADA Standards, 802.1.2).

Lines of sight and where the spaces go

Wheelchair spaces are an integral part of the seating plan (2010 ADA Standards, 221.2.2). The advisory note explains that they go within the footprint of the seating area: placing only the wheelchair spaces, or only the spaces and their companion seats, outside the seating areas defined by risers would be unacceptable (2010 ADA Standards, advisory 221.2.2).

The view counts as much as the place. Where spectators are expected to stay seated, a person in a wheelchair space sees over the heads of the seated spectators in the first row in front, or over their shoulders and between their heads, whichever the other seats are designed for; where spectators are expected to stand, the same applies over the people standing in front (2010 ADA Standards, 802.2.1 and 802.2.2). The spaces are also dispersed, so that wheelchair users have choices of location and viewing angle “substantially equivalent to, or better than” those of other spectators (2010 ADA Standards, 221.2.3). The advisory note puts it simply: they “need not be provided with the best seats in the house, neither may they be relegated to the worst” (2010 ADA Standards, advisory 221.2.3).

  • Side to side. The spaces are dispersed horizontally, which in an arena or stadium means around the field (2010 ADA Standards, 221.2.3.1 and its advisory). In a room with 300 or fewer seats this is not required if the spaces and companion seats are in the 2nd or 3rd quartile of the row length, intermediate aisles included; two wheelchair spaces may be side by side in row seating (2010 ADA Standards, 221.2.3.1, exceptions).
  • Front to back. The spaces are dispersed vertically, at varying distances from the screen, stage or field, and there are spaces in each balcony or mezzanine that is on an accessible route (2010 ADA Standards, 221.2.3.2). With 300 or fewer seats this is not required if the spaces have viewing angles equivalent to, or better than, the average in the facility; in bleachers, spaces are needed only in rows at points of entry, such as cross aisles, concourses, vomitories and entrance ramps and stairs (2010 ADA Standards, 221.2.3.2, exceptions, and advisory).
  • Stadiums, arenas and grandstands disperse the spaces to all levels that include seating served by an accessible route, and around the field where the seats encircle it. The spaces may not be on temporary platforms, unless a whole section is placed on temporary platforms where fixed seating is not provided (ADA Title III regulations, 28 CFR 36.406(f)(1) to (3)).
  • Stadium-style movie theaters put the spaces on a riser or cross-aisle in the stadium section, within the rear 60% of the seats or where the vertical viewing angles are between the 40th and 100th percentile (ADA Title III regulations, 28 CFR 36.406(f)(4)).

Once the required number of spaces has been met, further dispersion is not required, and team or player seating is exempt from these dispersion rules (2010 ADA Standards, 221.2.3 and its exception).

Companion seats, aisle seats and lawn seating

  • Companion seats. At least one for each required wheelchair space (2010 ADA Standards, 221.3). In row seating, it is placed for shoulder alignment with the wheelchair space, measured 36 inches (915 mm) from the front of the space, with its floor at the same level (2010 ADA Standards, 802.3.1). It is equivalent in size, quality, comfort and amenities to the seats around it, and it may be movable (2010 ADA Standards, 802.3.2).
  • Designated aisle seats. At least 5 percent of the aisle seats, chosen among those closest to accessible routes (2010 ADA Standards, 221.4). Where the seats around have armrests, these have folding or retractable armrests on the aisle side, and each one is identified by a sign or marker (2010 ADA Standards, 802.4.1 and 802.4.2). The advisory note says they are meant for people who have difficulty walking, and suggests contrasting, photoluminescent signs (2010 ADA Standards, advisory 802.4.2).
  • Which aisle seats. If only Aisle A has an accessible route to its top and bottom, the designated seats are those at the top and bottom of Aisle A, working toward the middle, before any seat on Aisle B (2010 ADA Standards, advisory 221.4). Team or player seating is exempt from the aisle seat rule (2010 ADA Standards, 221.4, exception).
  • Lawn seating and exterior overflow seating without fixed seats connect to an accessible route (2010 ADA Standards, 221.5).

Selling the accessible seats

The seats are only useful if they can be bought. Section 36.302(f) of the Title III regulation sets the ticketing rules:

  • Same chances. Tickets for accessible seating are sold during the same hours, in the same stages, such as presales, promotions, lotteries, wait-lists and general sales, through the same methods and outlets, and on the same terms as other tickets (ADA Title III regulations, 28 CFR 36.302(f)(1)).
  • Information. On request, the venue says where all unsold accessible seats are, describes them in enough detail to judge whether they fit, and marks them on seating maps and charts the same way as other seats (ADA Title III regulations, 28 CFR 36.302(f)(2)).
  • Price. Accessible seats cost no more than other tickets in the same seating section, and are available at all price levels (ADA Title III regulations, 28 CFR 36.302(f)(3)).
  • Friends and family. For each wheelchair space bought, three more tickets for seats in the same row, next to the space, are offered for sale if they are available (ADA Title III regulations, 28 CFR 36.302(f)(4)(i)).
  • Release. Unsold accessible seats may be released to other buyers only when all the other tickets, or all those in the same area or price category, are sold; luxury boxes, club boxes and suites are not counted. A venue never has to release them (ADA Title III regulations, 28 CFR 36.302(f)(5)).
  • Transfer and resale. Accessible tickets can be transferred on the same terms as other tickets, and a person with a disability who bought an inaccessible seat on the secondary market can exchange it for a vacant accessible seat in a comparable location (ADA Title III regulations, 28 CFR 36.302(f)(6) and (7)).
  • No proof. A venue may not ask for proof of disability, “including, for example, a doctor’s note”. For single events it may ask whether the buyer, or the person the tickets are for, has a mobility disability or needs the features of accessible seating; for a series, it may ask for a written attestation (ADA Title III regulations, 28 CFR 36.302(f)(8)).

Venues in Braillito Maps

Wheelchair spaces help only if you can reach them. Braillito Maps is a community map that answers ten questions about each place: step-free entrance or ramp, wide doorway, accessible restroom, accessible parking, tactile paving, braille signage, braille menu, audible signals, guide dogs welcome and a quiet environment.

Seating is not one of the ten, so the map does not record how many wheelchair spaces a theater has. Several of the ten still decide how a night out goes. Step-free entrance or ramp, wide doorway and accessible parking say whether you can get in from the street or the parking lot; parking is explained in accessible parking. Accessible restroom says whether there is one you can use during the show, and braille signage whether you can find your way inside. For people who are hard of hearing, the receivers and loops a venue provides are in ADA assistive listening systems. Guide dogs welcome says whether your dog can come in with you.

Each question is answered yes or no, or stays without data until someone knows. The score of a place is the number of yes answers out of ten, and its color always appears next to the number, never on its own. Only mark what you saw, and if what a place says is wrong, use “Report a problem”. Meet Braillito Maps.

Frequently asked questions

How many ADA wheelchair spaces are required?

It depends on the seats: 1 for 4 to 25, 2 for 26 to 50, 4 for 51 to 150, 5 for 151 to 300 and 6 for 301 to 500; from 501 to 5000, 6 plus 1 for each 150 or fraction, and over 5000, 36 plus 1 for each 200 or fraction (2010 ADA Standards, table 221.2.1.1).

What size is an ADA wheelchair space?

At least 36 inches (915 mm) wide, or 33 inches (840 mm) each where two are side by side, and at least 48 inches (1220 mm) deep when entered from the front or rear, or 60 inches (1525 mm) when entered only from the side (2010 ADA Standards, 802.1.2 and 802.1.3).

Yes. At least one companion seat for each required wheelchair space, in shoulder alignment with it and equivalent in size, quality, comfort and amenities to the seats around it (2010 ADA Standards, 221.3, 802.3.1 and 802.3.2).

What is an ADA designated aisle seat?

An aisle seat with a folding or retractable armrest on the aisle side, where the other seats have armrests, marked with a sign. At least 5 percent of the aisle seats are designated, those closest to accessible routes (2010 ADA Standards, 221.4, 802.4.1 and 802.4.2).

Can a venue charge more for accessible seats?

No. Tickets for accessible seating cost no more than other tickets in the same seating section, and are available at all price levels (ADA Title III regulations, 28 CFR 36.302(f)(3)).

Can a venue ask for proof of disability to sell wheelchair seats?

No proof, such as a doctor’s note. For a single event it may ask whether the tickets are for someone with a mobility disability or who needs the features of accessible seating; for a series, it may ask for a written attestation (ADA Title III regulations, 28 CFR 36.302(f)(8)).
