confused1 – perhaps read the posts HERE in the first instance.
Then, in the circumstances you describe where numerous owners both past and present have renovated their Units to the extent that the consent of the Owners Corporation (O/C) should have been granted beforehand, and other owners now want to, perhaps consider the O/C putting a generic “renovation by-law” on the Agenda of a General Meeting so that those present may consider and hopefully specially resolve to accept and Register it.
Such a by-law (special by-law actually) could, amongst other things, incorporate a provision that the owners of Lots, where renovations of a type that require the prior consent of the O/C have already been undertaken, could benefit from a moratorium of say 6 months during which time they could seek the O/C’s retrospective consent to those on the proviso that they agreed in writing to be responsible for all on-going maintenance of consequent changes to the common property arising from those (renovations), and to have all details recorded in a Register held and maintained by the O/C.
A further provision of the suggested special by-law would be that any owners who choose not to avail themselves of the moratorium by seeking the O/C’s retrospective consent would, prior to the settlement of any future sale of their Lot/s, suffer a notion on the Sect 109 Certificate provided by the O/C stating that its Register has “nothing shown” concerning consented changes to Common Property areas within the Lots; ipso facto any such changes are not consented and are not the responsibility of the O/C!
OK, those last six words (above) are a bit of a try-on, but just as the O/C’s consent may be granted retrospectively so may the provisions of a “renovation by-law” that’s properly passed at the General Meeting and Registered.
I’ve done precisely what I’ve suggested here for our Strata Plan, but as I’m not a Lawyer, I strongly suggest that IF your O/C decides to go this way then it engages one to assist.
