Illinois Administrative Code › Title 77 - PUBLIC HEALTH › Part 890 - ILLINOIS PLUMBING CODE › Subpart F - PLUMBING FIXTURES › Section 890.810 - Minimum Number of Plumbing Fixtures

Current through Register Vol. 48, No. 28, July 12, 2024
a)
				Minimum Number of Fixtures Required. Plumbing fixtures shall be provided, for
				each building type and occupant load, in the minimum numbers shown in Appendix
				A.Table B, Minimum Number of Plumbing Fixtures, except as noted in footnote 2.
				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. The Department's decision shall be
				in writing based on Appendix A.Table B.
1)
				Building Classification. For purposes of this Part, buildings shall be
				classified according to the types shown in Appendix A.Table B. Buildings that
				incorporate more than one type of building use or occupancy, as classified by
				the Department, shall provide the combined numbers of fixtures required for the
				individual uses. Individual businesses within the same building or within an
				enclosed mall may share public or employee restroom facilities, provided that
				the access to the restrooms does not require trespass on adjoining businesses
				or leased space. Restrooms shall be open at all times when any individual
				business within the same building or within an enclosed mall is open.
2) Occupant Load. For those building types
				for which the minimum number of plumbing fixtures required in Appendix A.Table
				B is dependent upon the building's occupant load, the occupant load shall be
				the estimated total occupant load. If the building's occupant load is not known
				or determinable, the following shall be used to estimate the total occupant
				load:
A) In assembly places (sports arenas,
				stadiums, convention centers, theaters, auditoriums, gymnasiums or other
				facilities for spectator events); worship places and funeral homes; schools;
				office buildings; food service establishments; and mercantile units, the total
				occupant load (employees and public users of the facility) shall be based on
				the capacity of the rooms or spaces used for assembly purposes or other
				intended occupancy and shall be determined as follows:
i) In rooms or spaces with fixed seating, the
				occupant load shall be the actual number of seats provided. When no divisions
				between seats are provided (e.g., benches or pews), fixed seating shall be
				computed assuming 18 inches per person.
ii) In rooms or spaces without fixed seating,
				the occupant load shall be determined by dividing the gross floor area by the
				estimated floor area per person shown in the following table:

iii)
				For a drive-in food service establishment, the occupant load shall be
				considered as equal to the number of parking stalls.
B) Dormitories and Institutions. For
				dormitories, penal institutions and other residential institutions other than
				hospitals, the total occupant load shall be based upon the number of beds in
				the dormitory or institution.
C)
				Restroom Location and Requirements. The required number of plumbing fixtures
				for a restroom shall be located within the restroom area and not in the
				hallways or vestibules. Lavatories required by Appendix A.Table B shall be
				installed in restrooms at a ratio of not less than one lavatory per two water
				closets or urinals. (See Footnote 2, Appendix A.Table B.)
