Balcony Balustrade Safety in Melbourne

Re-tiling or re-screeding a balcony can quietly change a balustrade from compliant to not. Adding height to the floor reduces the balustrade's effective height, and the Building and Plumbing Commission specifically calls this out as something to check.

What balcony balustrade safety in Melbourne actually involves

The Commission says balustrades must be at least one metre high, measured from the adjacent finished floor surface, and to check the height of a balustrade particularly if tiles or some other paving may have been applied after it was installed. A re-tile that adds even a little floor build-up can take a compliant balustrade under that line.

Openings and climbability

The Commission also says to check that there are no openings in the barrier that can permit a 125 mm sphere to pass through it, and that where it is possible to fall more than 4 metres, horizontal elements of the barrier between 150 mm and 760 mm do not facilitate climbing. Its guidance names concrete, steel and timber as the usual balustrade and handrail materials and says each needs to comply with the building regulations and standards on height, tension and fixings. This site takes these lines from the Commission's safety page, not from the regulations themselves.

Before the tiler starts

Ask whoever is re-tiling or re-screeding the balcony to check the finished balustrade height against the floor level the new surface will sit at, not the old one. A waterproofing or tiling contract does not itself cover balustrade compliance: attaching external fixtures, balustrades included, is its own line in the regulations' list of single-trade work, separate from waterproofing.

Steel near the water

The Commission says unprotected steel structures, reinforcing steel and fixings such as bolts and fixing plates can be corroded, particularly in coastal areas. If you are worried about the stability of a balustrade, it says to avoid the area, restrict access and contact a structural engineer or another suitably qualified building practitioner. The leaking balcony page covers the signs underneath.

Check the height from the new finished floor, not from where the floor used to be.
