2024 Ontario Building Code: Plumbing Fixture Requirements for Assembly, Child Care, and Care Occupancies
Sarah's Expert Insight
OBC Compliance Specialist
"The 2024 OBC updates place a significant emphasis on the ratio of fixtures to occupants in care facilities, which can heavily influence the floor plan efficiency of nursing homes in London or retirement residences in Oakville. At empcontracting.ca Inc. your construction contractor in London, Ontario, we find that early coordination between plumbing engineering and architectural layout is the only way to ensure these Group B washroom requirements don't lead to costly redesigns during the permit review process."
Compliance Standards for Plumbing in Assembly and Care Facilities
Understanding the nuances of the 2024 Building Code Compendium is essential for any major commercial or institutional development. Whether you are developing an assembly space or a specialized care facility, empcontracting.ca Inc. your construction contractor in London, Ontario, ensures your project adheres to the rigorous standards of Section 3.7.4.4. and associated tables.
Water Closets for Assembly Occupancies (Table 3.7.4.3.-H)
For assembly occupancies where fixture counts are tied to parking capacity, the OBC dictates a sliding scale of requirements. Starting from a single fixture for 1 to 40 spaces, the requirements scale up to 12 fixtures for 850 spaces, with an additional fixture required for every 100 spaces thereafter. Precision in these calculations is vital during the site planning phase.
Plumbing Fixtures for Child Care Facilities (Table 3.7.4.3.-I)
Child care facilities require age-specific plumbing considerations to ensure safety and hygiene:
- Under 5 years: 1 water closet and lavatory per 10 children (unisex).
- Ages 6 to 9: 1 fixture per 15 children, separated by sex.
- Over 9 years: 1 fixture per 30 males and 1 per 26 females.
Care, Treatment, and Detention Occupancies (3.7.4.4.)
In Group B occupancies, the code prioritizes patient accessibility and privacy. For Division 2 and 3 occupancies, washrooms must be accessible directly from sleeping rooms and serve no more than four residents. Each of these washrooms must contain at least one water closet and one lavatory to remain compliant with Ontario standards.
