Drinking Fountain Requirements in Ohio Commercial Buildings
By the ACC Solutions team
Short answer: Ohio's plumbing code requires drinking fountains in most commercial buildings, at rates set by occupancy (1 per 100 occupants in offices, 1 per 500 in restaurants, 1 per 1,000 in retail stores), and none at all when the occupant load is 15 or fewer. But Ohio changed one sentence of the national model code: in occupancies other than restaurants, providing a water dispenser means drinking fountains are not required. The model code only lets dispensers replace up to half. That one change can save a small business a fixture, a wall rough-in and an accessible-height alcove.
This guide is for owners, tenants and contractors planning a build-out in Cleveland or elsewhere in Ohio. It quotes the Ohio Plumbing Code, Chapter 4 (the 2021 International Plumbing Code as Ohio adopted it), Ohio's own amendments in OAC 4101:3-4-01 (effective October 15, 2025) and the federal 2010 ADA Standards, all read November 12, 2026. Your building department's plan reviewer makes the final call on your project. General information, not legal advice.
How many drinking fountains Ohio requires, by occupancy
The minimum comes from the drinking fountain column of Table 403.1. The table counts "one fixture being the minimum required for the number of persons indicated or any fraction of the number," and the occupant load comes from the building code. Common commercial rows:
| Occupancy (Table 403.1) | Drinking fountains |
|---|---|
| Business: offices, banks, professional services, ambulatory care, light industrial | 1 per 100 |
| Restaurants, banquet halls and food courts | 1 per 500 |
| Nightclubs, bars, taverns and dance halls | 1 per 500 |
| Mercantile: retail stores, service stations, shops, markets | 1 per 1,000 |
| Places of worship | 1 per 1,000 |
| Educational facilities | 1 per 100 |
| Factory and industrial | 1 per 400 |
| Storage and warehouses (low and moderate hazard) | 1 per 1,000 |
| Adult and child day care | 1 per 100 |
| Apartment houses; one and two family dwellings | None listed |
Because "any fraction" counts as one, a business space with an occupant load of 40 needs one drinking fountain under the table, the same as a space of 100. For the toilet and lavatory columns of the same table, see our guide to how many restrooms a commercial space needs in Ohio.
When you don't need a drinking fountain at all
- 15 or fewer occupants. Section 410.2: "Drinking fountains shall not be required for an occupant load of 15 or fewer."
- Restaurants that serve free water. Section 410.4: where restaurants provide drinking water in a container free of charge, drinking fountains aren't required in those restaurants.
- Other occupancies with a water dispenser (the Ohio change). Ohio replaced the last sentence of 410.4 to read: "In other occupancies where water dispensers are provided, drinking fountains are not required to be installed." The 2021 model code, as other states adopted it unchanged (for example Virginia's version), says dispensers may replace "not more than 50 percent" of required fountains, and only where three or more are required.
- Tenant spaces near a public fountain. Section 403.5: a tenant space doesn't need its own fountain if public drinking fountains are within 500 feet of travel from the most remote spot in the space and not more than one story up or down (300 feet in a covered or open mall).
What counts as a "water dispenser"
The code's definitions chapter calls a water dispenser "a plumbing fixture that is manually controlled by the user for the purpose of dispensing potable drinking water into a receptacle such as a cup, glass or bottle." It's connected to the building's potable water system, and the definition as shown for Ohio also covers a free-standing unit for the same purpose that isn't connected to the plumbing. Section 410.1 adds the product standards: drinking fountains, water coolers and dispensers must conform to NSF 61, Section 9, and electrically operated, refrigerated coolers and dispensers must be listed and labeled to UL 399.
In practice, a plumbed bottle-filling station or a listed water cooler is the type of dispenser plan reviewers expect to see. If you're relying on a free-standing bottled unit, put it on the drawings with its listing and ask the plan reviewer to confirm it before you skip the fountain rough-in.
Where fountains are required: the pair rule
When a fountain is required, one is not enough. Ohio's version of Section 410.3.1 says "not fewer than two drinking fountains are to be provided": one for people who use a wheelchair and one for standing persons. A single unit with two separate spouts that serves both can substitute for the pair. Above the minimum, Section 410.3.2 splits the fountains 50/50 between the two types.
The federal ADA Standards (Section 211) set the same pair rule, but they apply "where drinking fountains are provided," whether the plumbing code required them or not. The spout heights from Section 602:
- Wheelchair-accessible unit: spout 36 inches maximum above the floor, with knee and toe clearance for a forward approach.
- Standing-person unit: spout 38 inches minimum and 43 inches maximum above the floor.
So a single, voluntary drinking fountain in a space that didn't need one can still create an ADA question. If you're adding one, budget the hi-lo pair or a dual-spout unit.
One location you can't use
Section 410.5: "Drinking fountains, water coolers and water dispensers shall not be installed in public restrooms." Put them in a corridor or break area near the restrooms, which also keeps the supply line short.
A made-up example: a small office build-out
Every number here is invented to show how the rules stack. A tenant builds out an office space, and the plan reviewer sets the occupant load at 60.
- Table 403.1, business: 1 per 100, any fraction counts, so 1 drinking fountain is required.
- Section 410.3.1 (Ohio): where required, not fewer than two, a wheelchair unit and a standing unit, or one dual-spout unit.
- Section 410.4 (Ohio): if the tenant provides a water dispenser instead, such as a bottle-filling station in the break room, drinking fountains are not required.
- Section 403.5: if the building already has public fountains within 500 feet and one floor, the tenant may not need either.
Which route is cheapest depends on where the water line and drain already run. A dispenser that only needs a cold-water supply can be simpler than a fountain that needs a drain and a wall alcove sized for the hi-lo pair. Show your choice on the plumbing drawings so it's settled at plan review, not at the final inspection.
Pitfalls we see on drinking fountain questions
- Using the model code instead of Ohio's. Online summaries of the IPC say dispensers can only replace half. In Ohio, read OAC 4101:3-4-01 for the change.
- Forgetting the restaurant rule is different. Restaurants are exempt only if they provide free drinking water in a container. The Ohio dispenser sentence covers "other occupancies."
- Putting the cooler in the restroom. Section 410.5 prohibits it.
- Buying an unlisted cooler. Electric refrigerated units need UL 399 listing, and all units need NSF 61, Section 9.
- Skipping the occupant load. Every count in Table 403.1 starts from the occupant load the building code assigns, so get that number first.

Frequently Asked Questions
Are drinking fountains required in Ohio commercial buildings?
Usually, at rates set by occupancy in Table 403.1 of the Ohio Plumbing Code, such as 1 per 100 occupants in business spaces and 1 per 1,000 in retail. They are not required for an occupant load of 15 or fewer.
Can a water dispenser replace a drinking fountain in Ohio?
Yes. Ohio amended Section 410.4 so that in occupancies other than restaurants, where water dispensers are provided, drinking fountains are not required to be installed. The model code limits dispensers to 50 percent of required fountains.
Do restaurants in Ohio need a drinking fountain?
Table 403.1 lists 1 per 500 for restaurants, but Section 410.4 says drinking fountains are not required in restaurants that provide drinking water in a container free of charge.
How many drinking fountains do I need if one is required?
Ohio's Section 410.3.1 requires not fewer than two where drinking fountains are required: one for people who use a wheelchair and one for standing persons. A single unit with two spouts serving both can substitute.
Can a water cooler go in a public restroom?
No. Section 410.5 of the Ohio Plumbing Code says drinking fountains, water coolers and water dispensers shall not be installed in public restrooms.
