Balcony Waterproofing in Coorparoo
Coorparoo genuinely splits down the middle, and the two halves fail differently. Its post-war brick walk-ups put a balcony slab directly over the unit below, so the membrane is the body corporate’s rather than the noticing owner’s; on the older house half it is Brisbane City Council’s character overlay that sets what a rebuilt deck may be.

Balcony Waterproofing around Coorparoo
The split is almost exactly even — 49.9% flats or apartments against 40.6% separate houses at the 2021 Census. The house half includes a substantial pre-1946 stock, which brings Brisbane City Council's Traditional building character overlay into scope. Council's position is that owners in that overlay will generally need planning approval for external extensions — worth establishing before a deck rebuild is designed, because it can change what gets built.
Coorparoo has also been subject to its own district neighbourhood plan since 2019. Townhouses make up 9.3% of dwellings in Coorparoo.
Permits and Brisbane City Council rules
Coorparoo splits almost exactly down the middle, so both approval questions are live in the same postcode and neither answer transfers. A pre-1946 house sits inside Brisbane City Council's Traditional building character overlay, where Council states that owners "will generally need planning approval for external extensions" and that some renovations to a house built during or before 1946 require planning approval. A post-war walk-up two streets away sits under a body corporate, where Queensland Government guidance puts the lot boundary at "the face of the balcony" and keeps the membrane below with the body corporate. Establish which one you are before scoping anything. QBCC requires a waterproofing certificate — Form 43 or Form 12 — over $3,300 in both cases.
