Just curious what is the best practice or BCA codes requirements when it comes to the landscaping around your house in relation to levels and weep holes?
My front landscaping was done as part of my developer's package (free) and they've gone pretty quick in putting grass and garden beds in (pinebark style mulch).
The front garden's not the most level, but my most concern isn't the digout of soil and lack of lower level in the grass, but the fact that the garden bed is on line/just covering the weep holes around the fron tof my external render.
I did requires for leveling to be greater and the garden bed to sit below, but they mentioned supposedly they are allowed to cover the weep holes? My quick googling brings up some startling advice that covering weep holes with mulch is not ideal for the whole moisture/water expulsion purposes, let alone supposedly this encourages termites to physically enter. That said - wouldn't termites crawl up the wall into the weep holes regardless?
Just abit worried now as a few sites mention to pick more friendly options such as footpath, paving, or gravel/stone around the perimeter walls of your house - as opposed to mulch or garden beds. We've a small garden, but the garden bed begins from the walls.
Probably too late to move the garden bed and plants off from the wall - but should we at least be demanding the garden bed and mulch finish off below the weep holes?
Any BCA codes or regulation I can quote to get them to take action so they aren't responsible for issues?

In WA, anything seems to go regardless of what the National Construction Code (NCC) states about weep holes or the Damp Proof Course (DPC).
There are a few threads on Home one about the WA weep hole situation. The relevant Building Code of Australia (BCA) regulations can be found in those threads.The National Construction Code (NCC) comprises the BCA Parts 1 & 2 and the Plumbing Code of Australia (PCA) Part 3.
The threads below should interest you.
Just do a forum search for other threads.

Your window heads are in protected position under eaves and it is unlikely you will have a problem. From memory if a window or door is 1m or less it does not require a weep hole.
