Assembly-Area Seating on US Hotel and Conference Projects: What Sections 221 and 802 of the ADA Standards Say About Wheelchair Spaces, Companion Seats and Aisle Seats
Wheelchair spaces, companion seats and aisle seats, read from the text of sections 221 and 802
A hotel ballroom, a conference room, a lecture theatre, a chapel or a screening room has a seating plan, and the seating plan is part of the FF&E package. The ADA Accessibility Standards do not name a chair, a bench or a row by model or size. They say how many wheelchair spaces an assembly area has to provide, where they sit in the plan, what the companion seat beside each one is, and which aisle seats need folding armrests.
This article reads sections 221 and 802 as published on the US Access Board website, which we read on 27 October 2026; sections 221 and 802 matched the version we downloaded on 24 October 2026. FBM Furniture works with companies only: Developers · General Contractors · Builders · Commercial Project Owners · Interior Design & Construction Companies · FF&E Solution Providers. It sets out what the text says and does not decide whether any seating plan complies. We did not read the Department of Justice regulation itself, beyond the extract the Access Board page prints as a note, any Department of Justice guidance on loose or banquet seating, or any state or local code, which can add to these requirements. Your architect or accessibility consultant confirms what applies to the project.
What sections 221 and 802 cover, and the words “fixed seating”
Section 221.1 says: “Assembly areas shall provide wheelchair spaces, companion seats, and designated aisle seats complying with 221 and 802.” It adds that lawn seating shall comply with section 221.5, which requires lawn seating areas and exterior overflow seating areas, where fixed seats are not provided, to “connect to an accessible route”.
The counting rule in section 221.2 is narrower than the heading. It reads: “Wheelchair spaces complying with 221.2 shall be provided in assembly areas with fixed seating.” The count of wheelchair spaces is tied to fixed seating. The text of sections 221 and 802 does not itself say how a room set with loose chairs in rows for a single event is counted, and we did not read the Department of Justice guidance on that case. A buyer who supplies stackable or banqueting chairs for a ballroom should ask the project’s accessibility consultant how the venue’s plan treats them, instead of reading the table below as applying or not applying.
How many wheelchair spaces: Table 221.2.1.1
Section 221.2.1.1 sets the number from the total number of seats in the assembly area:
| Number of seats | Minimum number of required 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 |
As illustrations only: a room of 120 fixed seats falls in the 51 to 150 band and needs 4 wheelchair spaces; a room of 280 fixed seats needs 5; and a room of 600 fixed seats needs 6 for the first 500 plus 1 for the fraction of 150 above 500, which is 7 by our arithmetic. Boxes have their own wording: for luxury boxes, club boxes and suites in arenas, stadiums and grandstands the count is worked box by box and suite by suite, and for other boxes the wheelchair spaces must be located in not less than 20 percent of all boxes provided. Section 221.2.1.4 requires at least one wheelchair space in team or player seating areas serving areas of sport activity.
Where the spaces sit in the plan: integration, lines of sight and dispersion
Section 221.2.2 is one sentence: “Wheelchair spaces shall be an integral part of the seating plan.” The Advisory explains it with an example: they must be placed within the footprint of the seating area, and “Wheelchair spaces cannot be segregated from seating areas.” Placing only the wheelchair spaces, or only the spaces and their companion seats, outside the seating areas defined by risers is given as unacceptable.
Section 221.2.3 asks for lines of sight and dispersion: “Wheelchair spaces shall provide spectators with choices of seating locations and viewing angles that are substantially equivalent to, or better than, the choices of seating locations and viewing angles available to all other spectators.” The Advisory puts the intent in one sentence: “while individuals who use wheelchairs need not be provided with the best seats in the house, neither may they be relegated to the worst.” When the number required by section 221.2.1 has been met, further dispersion is not required.
The detail is in two sub-sections. Section 221.2.3.1 requires horizontal dispersion, with two exceptions: in assembly areas with 300 or fewer seats it is not required if the companion seats and the wheelchair spaces are located within the 2nd or 3rd quartile of the total row length, and in row seating “two wheelchair spaces shall be permitted to be located side-by-side.” Section 221.2.3.2 requires vertical dispersion: “Wheelchair spaces shall be dispersed vertically at varying distances from the screen, performance area, or playing field”, with spaces in each balcony or mezzanine on an accessible route, and an exception for assembly areas with 300 or fewer seats where the spaces provide viewing angles equivalent to, or better than, the average viewing angle in the facility.

Companion seats and designated aisle seats
Section 221.3 requires “at least one companion seat complying with 802.3” for each wheelchair space required by section 221.2.1. Section 802.3.1 sets the alignment: in row seating the companion seat is located to provide shoulder alignment with the adjacent wheelchair space, the shoulder alignment point is measured 36 inches (915 mm) from the front of the wheelchair space, and the floor surface of the companion seat is at the same elevation as the floor surface of the wheelchair space. Section 802.3.2 sets the type: “Companion seats shall be equivalent in size, quality, comfort, and amenities to the seating in the immediate area. Companion seats shall be permitted to be movable.” For a supplier of the seating, that means the companion seat is specified to match the surrounding seating, and it may be a movable chair instead of a fixed one.
Designated aisle seats are counted differently. Section 221.4 requires that “at least 5 percent of the total number of aisle seats provided shall comply with 802.4 and shall be the aisle seats located closest to accessible routes”, with an exception for team or player seating areas. Section 802.4.1 says: “Where armrests are provided on the seating in the immediate area, folding or retractable armrests shall be provided on the aisle side of the seat.” Section 802.4.2 requires that each designated aisle seat be identified by a sign or marker, and the Advisory says that seats with folding or retractable armrests are intended for use by individuals who have difficulty walking. The armrest type is therefore a specification point for any seat designated under section 221.4.
The wheelchair space itself: section 802.1
Section 802.1 sets the space the furniture has to leave free. The numbers are in this table:
| Provision | What the text sets |
|---|---|
| 802.1.1 Surface | The floor or ground surface complies with section 302 and changes in level are not permitted; slopes not steeper than 1:48 are permitted |
| 802.1.2 Width | A single wheelchair space is 36 inches (915 mm) wide minimum; where two adjacent spaces are provided, each is 33 inches (840 mm) wide minimum |
| 802.1.3 Depth | 48 inches (1220 mm) deep minimum where the space can be entered from the front or rear; 60 inches (1525 mm) deep minimum where it can be entered only from the side |
| 802.1.4 Approach | Wheelchair spaces adjoin accessible routes, and accessible routes do not overlap them |
| 802.1.5 Overlap | Wheelchair spaces do not overlap circulation paths |
The text gives two widths, 36 inches for a single space and 33 inches for each of two adjacent spaces, and two depths, 48 inches and 60 inches, depending on how the space is entered. For a seating plan drawn in millimetres, the conversions printed in the text are 915 mm, 840 mm, 1220 mm and 1525 mm.
Lines of sight, and what the Access Board page prints from the Department of Justice
Section 802.2 covers lines of sight to the screen, performance area or playing field. Where spectators are expected to remain seated, a person in a wheelchair space is afforded a line of sight over the heads of the seated spectators in the first row in front, or between their heads where that is the line of sight provided to others; section 802.2.2 repeats the two cases for standing spectators. These rules depend on the tiering of the room, and the text gives no chair dimension for them.
The Access Board page also prints a note to the reader that sets out requirements from the Department of Justice standards. Two of them reach the furniture. The first is that wheelchair spaces and companion seats “are not located on (or obstructed by) temporary platforms or other movable structures”, with an exception for a seating section that is placed on temporary platforms in an area where fixed seating is not provided. The second is a rule for unused spaces: “When wheelchair spaces and companion seats are not required to accommodate persons eligible for those spaces and seats, individual, removable seats may be placed in those spaces and seats.” So a seating plan can show removable seats in the spaces when they are not in use, and the seats have to be removable.
What to put in writing before the seating is specified
The text turns into a short list of items to settle with the architect or accessibility consultant before seating is ordered. Each item maps to a provision above.
- Whether the room has fixed seating, loose seating or both, and the seat count the consultant uses for Table 221.2.1.1 (sections 221.2 and 221.2.1.1).
- The position of each wheelchair space in the seating plan, with the 36 or 33 inch width and the 48 or 60 inch depth shown, and the accessible route that adjoins it (section 802.1).
- One companion seat per wheelchair space, specified to match the surrounding seating in size, quality, comfort and amenities, and whether it is fixed or movable (sections 221.3 and 802.3).
- The designated aisle seats, being at least 5 percent of the aisle seats, with a folding or retractable armrest on the aisle side where the seating has armrests, and the sign or marker for each (sections 221.4, 802.4.1 and 802.4.2).
- Any removable seats that fill wheelchair spaces and companion seats when they are not needed (the Department of Justice note).
- Which state or local accessibility code applies to the project, since the Access Board text is not the only one.
Send the seating plan and the schedule together so that the package is quoted against the room it will sit in. For how FBM Furniture works with FF&E contractors, see our page for FF&E contractors.

Frequently asked questions
How many wheelchair spaces does an assembly area need?
Table 221.2.1.1 sets it by the number of seats: 1 space for 4 to 25 seats, 2 for 26 to 50, 4 for 51 to 150, 5 for 151 to 300 and 6 for 301 to 500, then 6 plus 1 for each 150 seats or fraction thereof from 501 through 5000. Section 221.2 ties the requirement to assembly areas with fixed seating.
What is a companion seat under the ADA Standards?
Section 221.3 requires at least one companion seat for each wheelchair space. Section 802.3 says it is located for shoulder alignment with the adjacent wheelchair space, at the same floor elevation, and equivalent in size, quality, comfort and amenities to the seating in the immediate area; it may be movable.
What is the width of a wheelchair space in an assembly area?
Section 802.1.2 sets a single wheelchair space at 36 inches (915 mm) wide minimum and each of two adjacent spaces at 33 inches (840 mm) wide minimum. Section 802.1.3 sets the depth at 48 inches (1220 mm) minimum for front or rear entry and 60 inches (1525 mm) minimum for side entry.
Which aisle seats need folding armrests?
Section 221.4 requires at least 5 percent of the aisle seats to be designated aisle seats, being those closest to accessible routes. Section 802.4.1 requires folding or retractable armrests on the aisle side of those seats where armrests are provided on the seating in the immediate area, and section 802.4.2 requires a sign or marker.
Can wheelchair spaces be placed on a temporary platform?
The Department of Justice requirement printed on the Access Board page says wheelchair spaces and companion seats are not located on or obstructed by temporary platforms or other movable structures, with an exception where an entire seating section is placed on temporary platforms in an area where fixed seating is not provided.
