BCA deckregulations

Trying to find out exactly what I need to do for footings and bearers for my deck and whether or not I need bracing. Bearers and joists are 50x 100 seasoned karri and deck boards are 22mmx 135mm seasoned karri.

Deck height in relation to termite barrier

Hi There,
I am planning on building a low deck in an area surrounded on 3 sides by external walls of my house. The walls are brick veneer with the usual termite barrier two bricks up form the footings.

Balustrading required?

Hello, I have a deck that is 800mm from the ground - so theoretically does not need balustrading. I want to put a fixed bench seat around the periphery - both for extra seating and as a physical barrier to prevent falling/tipping off deck.

This fixed seating would be 450mm from the deck floor ie 1250mm from ground height. I do not want to have to put a seat back on the bench seating.

Do I now need balustrading behind the bench seating to comply with building laws?

Thank you

Decking - Permit requirements

Hi, I want to have a small deck built onto the side of our house, and we want it to adhere to the requirements of our local council (Darebin) so that our application will be granted a permit, but I am unable to find out what the can do's/can't do's are. Ie distance from boundary fence. Is there a resource for this information? I can't find it on any local council websites in Victoria.

Aluminium balustrading


I'm hoping to use aluminium pool fencing (vertical poles as sold by Bunnings) for deck railing (approx 2 metres off the ground) with a horizontal timber railing above it.

Can you please confirm this material is legal to use for this.
