Minimum / Maximum Step Height

Adrian B · Aug 19, 2007 8:02 pm

Hi all,

Can anyione point me to, or advise me of the minimum and maximum step heights for timber steps? I am planning a merbau deck (70mm) to go over our concrete porch, but want to extend it out a little, so it will need a step.

I cant find anything on our council website, but I think it would be a building regulation height, not a council requirement?

This is for Hoppers Crossing in Melbourne.

Thanks in advance

Adrian,

The Building Code of Australia provies the information you need.

First some terms. Rise is the height between steps and Going is the length of the flat bit.

The requirements are:
1) Rise = 115 to 190 mm
2) Going = 240 to 355 mm (preferably 265 to 355 mm)
3) 2 x Run + Going = 550 to 700 mm

Cheers,
Casa

I have no actual knowledge about this, and the previous post seems to have answered the question, but....

Isn't it also a requirement that the steps are fairly consistent in dimensions? (ie. Each step should be about the same rise and going in each flight) I thought this was so, but I may be wrong.
