Local notes
Before we start in Centennial Park
What can change a waterproofing job here, and what it means for you.
Who approves the work
Almost all Centennial Park homes are apartments, many of them in towers. Balcony and common-property repairs need the owners corporation's approval.
Heritage areas
Nearly all of Centennial Park is in four heritage conservation areas under Randwick's planning rules, the largest being North Randwick. New balcony tiles, balustrades or roof membranes generally need council consent.
