§411. Minimum Plumbing Fixtures

A. General. The following general requirements are to be used when applying Table 411 of this Part.

1. Restroom Plumbing Fixtures. Notwithstanding the provisions of LAC 51:I.123.A.2, in new construction, substantial renovation or building additions and in changes of occupancy classification or real property ownership, at least the minimum type(s) of rest room plumbing fixtures provided for in this Section shall be installed, and the minimum number of each type of restroom plumbing fixture shall be in accordance with Table 411 of this Part. The term "substantial renovation" as used in this Paragraph includes, but is not limited to, a renovation/operational change which would trigger the need, pursuant to the requirements of Table 411 of this Part, for additional restroom plumbing fixtures to be installed, even if the occupancy classification itself may not have changed.

a. Exception

i. When only a real property ownership change occurs, restroom plumbing fixture upgrades to meet the minimum plumbing fixture requirements contained in this Section and Table 411 of this Part are not to be blindly enforced if the state health officer/Office of Public Health has assurances that the prior or existing business held a food permit (e.g., grocery store, restaurant, etc.) under LAC 51:XXIII and the prospective new business owner agrees, in writing to the state health officer/Office of Public Health, to operate the business in exactly the same manner as the prior or existing business owner (e.g., parents sell a business to their children who will operate the business in exactly the same manner) and there have been no documented complaints, within the past five years, about:

(a). a lack of toilet room fixtures;

(b). urination in non-restroom fixtures or floor areas within the building; or

(c). urination on the outside of the building or the premises or adjoining lots or areas, etc.

ii. This exception to the normal enforcement procedures (i.e., §411.A.1 of this Code) shall not be applicable when a serious health threat to the public exists.

2. Non-Restroom Plumbing Fixtures. Where the construction of buildings and facilities was approved by the state health officer pursuant to Sanitary Code (LAC 51) requirements then in effect, upgrading of such buildings and facilities to comply with the non-restroom plumbing fixture requirements of Table 411 of this Part shall not be required except where:

a. substantial renovation or building additions are undertaken; or

b. where the occupant or real property ownership thereof or the occupancy classification located therein changes subsequent to the effective date hereof; or

c. where a serious health threat to the public health exists, unless otherwise specifically provided hereinafter.

3. The term "substantial renovation" as used in §411.A.2 of this code includes, but is not limited to, a renovation/operational change which would trigger the need, pursuant to the requirements of Table 411 of this Part, for additional non-restroom plumbing fixtures to be installed, even if the occupant or the occupancy classification itself may not have changed.

4. Except as may be otherwise specifically noted within Table 411 of this Part, the number of occupants of a building shall be determined by the square feet (sq ft) of usable floor space. In determining the usable floor space, the square foot area of permanent structural building components, food service establishment kitchens, toilet rooms, corridors, stairways, vertical shafts and equipment rooms, when necessary for the operation of building utilities only, may be deducted from the total aggregate floor area. The occupant content and the number of required facilities for occupancies other than listed in Table 411 of this Part shall be determined by the plumbing official. Plumbing facilities in the occupancies or tenancies of similar use may be determined by the plumbing official from Table 411 of this Part.

5. In commercial buildings of multiple tenants, common toilet facilities (separate for males and females) for each floor are acceptable in lieu of separate facilities required by this Section only when the applicable building occupant content has common access from within the building. Central facilities shall be installed such that the path of travel to such facilities shall not exceed a distance of 500 feet. The maximum travel distance to the central toilet facilities shall be measured from the main entrance of any store or tenant space. When tenancies, rental units, etc., are to be provided with separate facilities of a partial nature, such facilities are not deductible from the total common facilities required. Tenancies, rental units or other usable areas within a building when separated from the required toilet facilities by walls or partitions without common access openings (i.e., openings through interior walls or partitions that allow access to the toilet facilities) shall be considered independently from the remainder of the building and shall be provided with separate facilities in accordance with this Chapter regardless of the type of occupancy.

6. In self-storage (mini-warehouse) complexes, facilities shall not be required in each building, but shall be located at the office or entrance and such that the plumbing official determines the intent of the code is satisfied (see Paragraphs 7 and 8 in §411.A of this Code below).

7. In applying the schedule of facilities recorded in Table 411 of this Part, consideration must be given to the accessibility of the fixtures. Conformity purely on a numerical basis may not result in an installation suitable to the need of the individual establishment. For example, multi-storied buildings shall be provided with toilet facilities on each floor based upon the population of the floor. If building is a multi-purpose facility (i.e., a retail fuel station and a retail store, or a retail fuel station and a retail store and a restaurant, or a retail store and retail fuel station, etc.), the occupancy which requires the largest number of fixtures shall apply.

8. Every building and each subdivision thereof intended for public use shall be provided with facilities in accordance with this Chapter. Required facilities shall be directly accessible to the public through direct openings or corridors from the area or areas they are intended to serve. Access to the required toilet facilities for customers shall not pass through areas designated as for employee use only such as kitchens, food preparation areas, storage rooms, closets or similar spaces. Toilet facilities accessible only to private offices shall not be counted to determine compliance with this Chapter. Required facilities shall be free and designated by legible signs for each sex. Pay facilities may be installed when in excess of the required minimum facilities.

9. The toilet room entry door shall not be lockable by a user of the facilities when such room contains multiple water closets (or water closet and urinal fixtures) and the fixtures provided therein are required to meet the minimum number of plumbing fixtures required in accordance with Table 411 of this Part.

10. The "Persons (total)" column included in the following Table 411 below is based upon a 50 percent male to 50 percent female ratio.
