Hi All,
There is mostly a very fundamental by-law in most strata schemes that says an owner or occupier can not damage common property. This is basic stuff and an EC decision to require permission to be applied for first in most circumstances is supported by this by-law.
Let’s get real about Real Estate signs though. Most of these are just advertising for agents, more so than the owners property. Good agents will be respectful to the OC and seek permission prior to erecting the sign.
