For: Dealers, developers, property managers and hotel operators specifying a fitness room in a residential, hotel or office building that runs without staff.
The decision: Which machines, and how many, the room can hold, built up from manufacturer clearances, accessibility requirements and the delivery path rather than from a square-foot rule.
60-second answer: No code or standard FEX found sets a machine count per square foot, so the earlier room-size bands have been removed. Draw each machine’s footprint plus the manufacturer’s stated clearance: Precor’s TRM 800-series guide, for example, calls for 0.5 m (19.7 in.) on each side and 2 m (78 in.) behind a treadmill, and Concept2 recommends a 60 by 48 inch area for its BikeErg. Where the ADA applies, add a 30 by 48 inch clear floor space for at least one machine of each type (these may overlap) on an accessible route at least 36 inches wide; the Access Board treats each kind of cardio machine, and most strength machines, as separate types. Whatever still fits is the count. Then check door widths against crated sizes, circuits against nameplates, and who will inspect the room.
Build the count from clearances, not a square-foot rule
Specifying amenity gym equipment differs from specifying a club floor because nobody is standing there. There is no attendant to correct use, tag a broken machine or keep a walkway clear, so the layout has to do that work. The reliable way to size the room is to build it up from documented space requirements:
- Usable floor. Measure the room, then take out door swings, columns, the circulation path, towel and water stations, and any mirror or wall setback.
- Footprints. Place each candidate machine at its manufacturer-stated footprint, using the dimensions for the exact model.
- Manufacturer clearances. Add the clearance each manufacturer specifies. Precor’s assembly guide for its TRM 800-series treadmills calls for “a minimum of 0.5 m (19.7 in.) on each side” and “2 m (78 in.) behind the machine,” says the area directly behind the running belt must stay open, and notes the figures are based on a combination of ASTM voluntary standards and EN regulations as of October 1, 2012. Concept2 recommends an area of 60 by 48 inches for operating its BikeErg. Where a manual gives no clearance, ask the manufacturer in writing.
- Accessibility. Where the ADA Standards apply, add the clear floor space and route described below.
- Count what fits. The number of machines is the result of the drawing, not the starting point.
Clearance zones should not double as the circulation path. If the plan only works because a walkway runs through the space behind a treadmill, there are too many machines.
Accessibility: what applies and what it requires
Which rules govern depends on the building. HUD’s summary says the ADA primarily covers public facilities such as restaurants, hotels and parks, but also that “Title III requires that public and common use areas at housing developments are accessible,” and that Title II covers housing provided by state and local governments. Separately, the Fair Housing Act sets accessibility requirements for multifamily buildings of four or more units built for first occupancy after March 13, 1991. Whether a residents-only amenity room, a hotel fitness center or an office tenant gym falls under the ADA Standards, the Fair Housing Act or a local code is a question for the project’s accessibility consultant or counsel. Where the 2010 ADA Standards apply, the US Access Board summarizes the requirements this way:
- “At least one of each type of exercise machine and equipment” must comply with Section 1004. The Access Board’s advisory says “most strength training equipment and machines are considered different types” (a biceps curl machine and a cable cross-over machine must both comply), and that each kind of cardio machine, such as a stationary bicycle, rowing machine, stair climber or treadmill, “is considered a different type.” A room with a treadmill, a bike and an elliptical therefore needs an accessible option of each.
- Each of those machines needs a clear floor space complying with Section 305, 30 by 48 inches, “positioned for transfer or for use by an individual seated in a wheelchair.”
- Clear floor spaces for more than one piece of equipment can overlap, which is what makes compliance workable in a small room.
- The required machines must be on an accessible route; the Access Board’s guide gives a 36-inch minimum continuous clear width, which may narrow to 32 inches at points such as doorways for no more than 24 inches.
- Exercise machines are exempt from the operable-parts requirements.
The detailed layout method is in planning clear floor space and routes together. For the equipment itself, ASTM F3021-23 is the specification for universal design of commercial fitness equipment for inclusive use, intended for indoor commercial use by people aged 13 and above, including users of manual or powered wheelchairs; ASTM notes that products meeting it are not automatically fit for medical or rehabilitation purposes. Naming it in the purchase specification gives the buyer something specific to ask suppliers for.
What an unstaffed room should carry
This section is FEX analysis. With no supervision, choose equipment whose safe use does not depend on someone watching: selectorized stations with enclosed weight stacks, fixed dumbbells stored on a rack, cable stations with intact guarding, and treadmills whose emergency stop is tested on a schedule. Loose barbells, bumper plates and plate-loaded stations need loading discipline and floors that tolerate drops; leave them out unless the owner accepts that risk in writing. Keep manufacturer warning labels on the machines, check them on every visit, and test treadmill stop functions on the inspection schedule. Use commercial or light-commercial equipment whose warranty covers shared use; read the use classification rather than assuming it.
Delivery path, power and service
Delivery. Amenity rooms can sit on upper floors, below grade or at the end of a residential corridor. A door that meets the ADA’s 32-inch minimum clear width can still be too narrow for a crated machine. Ask for crated and uncrated dimensions, minimum knock-down width and reassembly time before the order, and walk the route as in the delivery site survey. Above grade, the floor itself is a structural question.
Power and air. Motorized treadmills carry specific circuit requirements; Precor, for example, requires its TRM 800-series treadmills to be on “a 20 amp individual branch circuit” that can be shared only with one PVS, Precor’s attached personal viewing system. An amenity room may be fed from a common-area panel sized for other loads, so confirm circuits against each model’s nameplate with the building engineer before the order, and ask the same engineer about ventilation and cooling for the room’s planned use. The schedule is in cardio electrical requirements.
Service. Without staff, a fault can go unreported until a user complains. Contract scheduled inspection visits rather than reactive calls, and keep the visit records; the model is in building an inspection service.
Checking the plan before ordering
| Check | Plan works as drawn | Re-plan before ordering |
|---|---|---|
| Manufacturer clearances | Each machine’s stated clearance drawn and kept clear of walkways | Clearance missing from a manual and not obtained, or overlapping the walkway |
| Accessibility, where it applies | At least one machine of every type (each cardio kind, each distinct strength machine) has a 30 by 48 inch clear floor space on a 36-inch route | Only one cardio and one strength machine made accessible, any type without clear floor space, or a route that pinches below the allowed width |
| Equipment mix | Safe use does not depend on supervision | Loose plates, bars or plate-loaded stations without a written owner decision |
| Delivery path | Crated and knock-down dimensions clear every door, turn and elevator | Dimensions not checked against the route |
| Power | Circuits match each model’s nameplate and manual | Treadmills assumed to share the existing common-area circuits |
| Service | Scheduled inspections contracted and records kept | Fault reporting relies on residents or guests |
What to do this week
- Collect footprint and clearance figures from the manual for every candidate model, and ask in writing where a manual is silent.
- Draw the room with clearances, walkways and, where the ADA applies, a clear floor space for at least one machine of each type and the accessible route; count what fits.
- Ask the accessibility consultant which accessibility rules apply to this room.
- Check crated and knock-down dimensions against every door and elevator on the route.
- Confirm circuits and ventilation with the building engineer and contract scheduled inspections.

FEX editorial guidance: the layout method, equipment-mix guidance and plan check are FEX analysis. Clearances are the cited manufacturers’ figures for the named models; use the figures for the models you buy. This is not legal or accessibility-compliance advice: confirm which accessibility rules apply with an accessibility consultant or counsel, and electrical, ventilation and structural questions with the building’s engineers.
