2024 Ontario Building Code: Public Spa Accessibility and Water Circulation Standards
Sarah's Expert Insight
OBC Compliance Specialist
"At empcontracting.ca Inc. your construction contractor in London, Ontario, we emphasize that meeting turnover rates for small-volume spas is critical for health compliance in Oakville or Muskoka commercial projects. Ensuring precise transfer wall measurements during the framing stage prevents expensive retrofits, guaranteeing your facility is both inclusive and fully OBC-compliant."
Navigating the 2024 Building Code Compendium is essential for developers and facility managers across Ontario. Specifically, Sections 3.12.3.2 and 3.12.4.1 outline the mandatory requirements for accessibility and sanitation in public spas. At empcontracting.ca Inc. your construction contractor in London, Ontario, we specialize in ensuring these technical specifications are met with precision during the design and build phases.
3.12.3.2. Barrier-Free Access into Public Spas
Accessibility is a cornerstone of the modern Ontario Building Code. Where a suite is required to have a barrier-free path of travel, at least one public spa must be accessible via one of three methods: a ramp, a pool lift, or a transfer wall.
Transfer Wall Requirements
If a transfer wall is used for entry and egress, it must strictly adhere to the following dimensions:
- Height: Between 405 mm and 485 mm from the pool deck.
- Depth: Between 300 mm and 400 mm.
- Surface: Must be slip-resistant with rounded edges.
- Grab Bars: At least one slip-resistant grab bar perpendicular to the pool, extending the full depth of the wall, located 100 mm to 150 mm above the wall surface.
Clear Deck Space and Lateral Transfer
To facilitate a safe lateral transfer, the deck must provide a clear space of 900 mm by 2 200 mm. This area must have a slope of less than 2% and remain free of any obstructions to ensure unhindered movement for individuals using mobility devices.
3.12.4.1. Water Circulation Systems for Public Spas
Proper water turnover is critical for public health. The OBC dictates specific turnover periods based on the volume of the spa to ensure water is filtered and disinfected effectively.
Turnover Rate Requirements
- Volume > 6 m³: Maximum 30-minute turnover period.
- Volume 4 m³ to 6 m³: Maximum 20-minute turnover period.
- Volume < 4 m³: Maximum 15-minute turnover period.
Additionally, if cartridge-type filters are utilized, they must be surface-type and designed for a maximum flow rate of 0.27 L/s/m² of effective filter area. For expert implementation of these standards, trust empcontracting.ca Inc. your construction contractor in London, Ontario.
