Instructions/Footnotes For Table B
The numbers of fixtures required for employees are included
					 in the numbers shown in Table B for all building types/uses except Hospital
					 Rooms, Penal Institutions, and Other Institutions. The entry in Table B
					 entitled "All Facilities for Employee Use" shall be used to determine the
					 minimum number of fixtures required for employees in hospitals, penal/other
					 institutions, and all other buildings/facilities that do not appear in Table
					 B.
Questions concerning the minimum numbers of fixtures
					 required for building types not listed in Appendix A, Table B, shall be
					 referred to the Department in writing prior to construction for a decision
					 concerning the minimum numbers (and types) of plumbing fixtures
					 required.
Footnotes:
1. The figures shown are the minimum number of fixtures
					 required for the number of persons indicated or any fraction of that number.
					 Based on the total occupant load determined, the number of fixtures shall be
					 calculated assuming 50 percent of the occupants are male and 50percent are
					 female. The total male/female occupants shall be calculated first; then the
					 number of fixtures for each (males/females) shall be determined from the
					 appropriate table.
2. Urinals may be substituted for water closets for males,
					 not to exceed half of the required total number of water closets. Comparable
					 fixtures for females may be substituted for water closets for females, not to
					 exceed half of the required total number of water closets.
3. 18 lineal inches of wash sink or 18 inches of a circular
					 basin, when provided with water outlets for space of this kind, shall be
					 considered equivalent to one lavatory.
4. Whenever a drinking fountain is required by this Part,
					 bottled drinking water or a water dispensing faucet (water station) may be
					 substituted for a drinking fountain, provided drinking water is accessible to
					 the public. When bottled drinking water is provided in lieu of a drinking
					 fountain, the bottled water used must be commercially sealed in accordance with
					 the Illinois Bottled Water Act and with the Illinois Safe Bottled Water
					 Act.
5. The kitchen sink and laundry tray or connection for the
					 washer are not required for the hotel/motel unit.
6. In addition to providing separate hand-washing
					 facilities in the kitchen for employees, all food service establishments shall
					 provide a minimum of one service/utility sink and one three-compartment sink to
					 sanitize dishes and eating utensils; however, a mechanical dishwasher may be
					 substituted for a three-compartment sink to sanitize dishes and utensils. (See
					 77 Ill. Adm. Code 750.)
7. Bathtubs/showers that are required for employees by OSHA
					 requirements, collective bargaining agreements, etc., shall be provided at the
					 rate of one per 10 employees.
8. Food Service Establishments with no more than 10
					 combined employees and seats (for patrons) at any one time need not provide
					 public restrooms, provided that the employee restrooms are accessible and made
					 available to the public.
9. Bed and Breakfast facilities with more than five
					 sleeping rooms shall meet the minimum requirements of this Part for Hotel/Motel
					 units. Bed and Breakfast facilities with five or fewer sleeping rooms, in
					 compliance with the Bed and Breakfast Act, need not provide individual
					 restrooms for each sleeping room.
10. Businesses that sell motor fuel but do not have any
					 employees working as attendants are not required to provide public
					 restrooms.
11. In Day Care Centers providing restroom training
					 facilities for occupants ages three and younger where continuous adult
					 supervision is provided, restrooms are not required to be separated into
					 facilities for males and females, and are allowed to contain multiple
					 lavatories and water closets as required by this Part. Public restrooms shall
					 be required for everyone over the age of three separate from the restroom
					 training facilities as required by this Part.
12. Drinking water shall be provided in accordance with
					 Section
					 890.720(f).
13. The total number of bathing facilities shall include
					 one bathtub for males and one bathtub for females or one individual user
					 restroom with a bathtub.
