Accessible Routes and Protruding Objects in Hotel Lobbies and Restaurants: What ADA Sections 307, 402 and 403 Say About Furniture Layouts
Clear width, protruding objects and clearances on a circulation path, read from the text of sections 206.2.4, 307, 402 and 403
A furniture package is priced from a schedule of items, but a lobby, a restaurant floor or a corridor is judged by the space left between them. In the ADA Accessibility Standards that space has numbers: the clear width of the route, the distance an object may stick out into it, and the clearance overhead. None of these sections names a table, a bench or a wall-hung shelf, and all three decide where such items can go.
This article reads sections 206.2.4, 402 and 403 on accessible routes, section 307 on protruding objects, and the dimensions they borrow from sections 304 and 305, as published on the US Access Board website. We read chapters 2 and 3 on 24 October 2026 and chapter 4 on 25 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 layout or piece of furniture complies. We did not read the sections on doors, ramps or wheelchair spaces, the Department of Justice regulation itself, or any state or local code, which can add to or replace these requirements; your architect or accessibility consultant confirms what applies to the project. Our earlier notes in this series cover guest rooms (sections 224 and 806), dining surfaces (sections 226 and 902) and service counters (sections 227.3 and 904.4).
Which paths have to be accessible routes
Section 206.2.4 states that at least one accessible route shall connect accessible building or facility entrances with “all accessible spaces and elements within the building or facility which are otherwise connected by a circulation path”, unless exempted by the exceptions to section 206.2.3. For a hotel lobby, a restaurant or a function room, the practical reading is that the path from the entrance to each accessible space is an accessible route.
Section 402.2 says an accessible route consists of one or more of these components: walking surfaces with a running slope not steeper than 1:20, doorways, ramps, curb ramps, elevators and platform lifts, and that “all components of an accessible route shall comply with the applicable requirements of Chapter 4”. Section 403 then sets the requirements for the walking surfaces. Section 403.5 makes the clearances apply to them, with one exception for employee work areas: there, clearances on common use circulation paths may be decreased by work area equipment if the decrease is essential to the function of the work being performed.
Clear width: 36 inches, and what changes it
The number that sets a layout is in section 403.5.1: “the clear width of walking surfaces shall be 36 inches (915 mm) minimum”, except as provided in 403.5.2 and 403.5.3. The three paragraphs together read as follows.
| Provision | What the text sets |
|---|---|
| 403.5.1 Clear width | 36 inches (915 mm) minimum, except as provided in 403.5.2 and 403.5.3 |
| 403.5.1 Exception | 32 inches (815 mm) minimum for a length of 24 inches (610 mm) maximum, provided the reduced-width segments are separated by segments at least 48 inches (1220 mm) long and 36 inches (915 mm) wide |
| 403.5.2 Clear width at turn | Where the route makes a 180 degree turn around an element less than 48 inches (1220 mm) wide: 42 inches (1065 mm) minimum approaching the turn, 48 inches (1220 mm) minimum at the turn and 42 inches (1065 mm) minimum leaving it; not required where the clear width at the turn is 60 inches (1525 mm) minimum |
| 403.5.3 Passing spaces | A route narrower than 60 inches (1525 mm) provides passing spaces at intervals of 200 feet (61 m) maximum, each either a 60 by 60 inch (1525 by 1525 mm) minimum space or the intersection of two walking surfaces forming a T-shaped space whose base and arms extend 48 inches (1220 mm) minimum beyond the intersection |
Two points follow from the wording. First, the width is a clear width: the dimension between obstructions along the route, not the width of the floor. A route that is 40 inches between walls is narrower where a chair back, a planter or a bench projects into it. Second, a route can be narrower than 36 inches only in the short segments the exception allows, and the rest of the route has to be 36 inches wide or more. The Figure for 403.5.1 shows the same thing in plan: the reduced-width segments are at least 48 inches apart.
Section 403.5.2 matters for a layout that makes a route double back around a free-standing element such as a column, a bar return or a display unit. The 42, 48 and 42 inch figures apply when that element is less than 48 inches wide; with a clear width of 60 inches at the turn, the paragraph does not apply. Section 403.5.3 matters for long routes: a route narrower than 60 inches has passing spaces at intervals of 200 feet maximum.
Protruding objects: the 4 inch rule
Section 307 covers the objects that stick out into a circulation path. Its limits are set by height above the floor and by how far the object projects.
| Provision | Limit |
|---|---|
| 307.2 Protrusion limits | Objects with leading edges more than 27 inches (685 mm) and not more than 80 inches (2030 mm) above the finish floor protrude 4 inches (100 mm) maximum horizontally into the circulation path (handrails 4½ inches (115 mm) maximum) |
| 307.3 Post-mounted objects | Free-standing objects mounted on posts or pylons overhang the circulation path 12 inches (305 mm) maximum when located between 27 and 80 inches above the floor; where a sign or other obstruction is mounted between posts more than 12 inches apart, its lowest edge is 27 inches maximum or 80 inches minimum above the floor |
| 307.4 Vertical clearance | 80 inches (2030 mm) high minimum; guardrails or other barriers where it is less, with the leading edge of the barrier 27 inches (685 mm) maximum above the floor; door closers and door stops may be 78 inches (1980 mm) minimum |
| 307.5 Required clear width | Protruding objects shall not reduce the clear width required for accessible routes |
The Advisory to 307.2 explains the reason: when a cane is used and the element is in the detectable range, it gives a person sufficient time to detect the element with the cane before there is body contact. It also gives examples, stating that elements located on circulation paths, including operable elements, must comply with the requirements for protruding objects, that awnings and their supporting structures cannot reduce the minimum required vertical clearance, and that casement windows, when open, cannot encroach more than 4 inches into circulation paths above 27 inches.
The text does not list furniture. It limits any object whose leading edge is more than 27 inches and not more than 80 inches above the floor. The illustration for 307.2 shows a wall-mounted object protruding no more than 4 inches from the wall and an object overhead with more than 80 inches of vertical clearance, and the illustration for 307.3 shows objects mounted on posts. Whether a wall-hung shelf, a bracket or a light fitting in a corridor, or a free-standing piece placed beside a path, falls inside these limits is a question about where the circulation path runs and where the object sits, which belongs to the design team and not to the schedule of items.

Turning space and clear floor space where routes meet furniture
Two other dimensions come up wherever an accessible route ends at a seat, a table or a counter. Section 304.3 sets turning space as either a circular space of 60 inches (1525 mm) diameter minimum or a T-shaped space within a 60 inch square with arms and base 36 inches wide minimum, with each arm clear of obstructions 12 inches minimum in each direction and the base clear 24 inches minimum. Changes in level are not permitted in a turning space (section 304.2), and doors are permitted to swing into turning spaces (section 304.4).
Section 305.3 sets clear floor space at 30 inches (760 mm) minimum by 48 inches (1220 mm) minimum, and section 305.6 requires that one full unobstructed side of it adjoin an accessible route or another clear floor space. Where a clear floor space sits in an alcove confined on three sides, section 305.7 adds maneuvering clearance: alcoves 36 inches wide minimum where the depth exceeds 24 inches for a forward approach, and 60 inches wide minimum where the depth exceeds 15 inches for a parallel approach.
What to put in writing before the layout is fixed
The text turns into a short list of items to settle with the architect or accessibility consultant before furniture is ordered. Each item maps to a provision above.
- Which paths are accessible routes under section 206.2.4, marked on the plan the furniture is laid out against.
- The clear width at the narrowest point of each route, measured between the furniture as laid out and the walls or other fixed elements, against the 36 inch figure in section 403.5.1 and the exception that allows 32 inches for no more than 24 inches of length.
- Any route that turns around a free-standing element, checked against section 403.5.2.
- Every wall-mounted, post-mounted or overhead item on or beside a circulation path, with its projection and the height of its leading edge, against sections 307.2 to 307.4.
- The turning spaces and clear floor spaces at the points where routes meet seating, tables and counters (sections 304.3 and 305.3).
- Which state or local accessibility code applies to the project, since the Access Board text is not the only one.
Send the plan and the schedule together, so that the package is quoted against the layout it will sit in. For how FBM Furniture works with FF&E contractors, see our page for FF&E contractors.
Frequently asked questions
What is the minimum width of an accessible route under the ADA Standards?
Section 403.5.1 sets the clear width of walking surfaces at 36 inches (915 mm) minimum. The exception allows 32 inches (815 mm) minimum for a length of 24 inches (610 mm) maximum, provided the reduced-width segments are separated by segments at least 48 inches long and 36 inches wide. Sections 403.5.2 and 403.5.3 set other figures for turns and passing spaces.
How far can a wall-mounted object protrude into a circulation path?
Section 307.2 says objects with leading edges more than 27 inches (685 mm) and not more than 80 inches (2030 mm) above the finish floor protrude 4 inches (100 mm) maximum horizontally into the circulation path. Handrails may protrude 4½ inches (115 mm) maximum.
What vertical clearance does the ADA Standards require on a circulation path?
Section 307.4 requires vertical clearance of 80 inches (2030 mm) high minimum. Where it is less, guardrails or other barriers are provided with the leading edge 27 inches (685 mm) maximum above the floor. Door closers and door stops may be 78 inches (1980 mm) minimum above the floor.
When does an accessible route need passing spaces?
Section 403.5.3 requires passing spaces at intervals of 200 feet (61 m) maximum on an accessible route with a clear width less than 60 inches (1525 mm). A passing space is a 60 by 60 inch minimum space, or the intersection of two walking surfaces forming a T-shaped space whose base and arms extend 48 inches minimum beyond the intersection.
Does the ADA Standards set dimensions for the furniture itself?
Not in the sections we read. Sections 307, 402 and 403 set the route width, the limits for objects projecting into a circulation path and the overhead clearance. They do not name tables, benches or shelves, so the furniture schedule and the plan have to be checked together against them.
