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.
