Understanding New Drainage Requirements for Home Builders

Recent updates to the National Construction Code (NCC) have revised requirements for floor drainage in new residential builds. Homeowners should be aware that separate dry floor wastes are no longer mandatory in most wet areas outside of showers.

Key Takeaways

1

Shower Drains Now Mandatory

Under the latest NCC guidelines, only showers are required to have a drainage point. This change simplifies construction and focuses on essential water management areas.

2

Other Wet Areas Exempt

Bathrooms, ensuites, powder rooms, and laundries do not require a separate dry floor waste. While not mandatory, homeowners can still opt to include them for added protection.

3

Fixture-Based Water Management

The code now relies on fixtures like baths, basins, and laundry machines to manage overflows and discharges effectively. This ensures water is contained at the source, reducing the need for general floor drainage.

4

Potential Cost Implications

If you choose to install floor wastes in areas where they are no longer required, your builder may charge an additional fee as it deviates from the standard NCC compliance.
