When is the authorisation of OC required?

Can obtain some guidance on when an owner has to notify the OC or EC regarding renovations and or alterations to their individual unit.

I would expect that if their works involve any common property they would definitely need to notify, but what about installation of a new kitchen or bathroom?

We have the standard By-laws of the SSM ACT which covers “Damage to common property”, nothing on gaining permission for or notifying of renovations and or alterations.

I note that Sec. 116 (2) “The owner of a lot must not alter the structure of the lot without giving to the owners corporation, not later than 14 days before commencement of the alteration, a written notice describing the proposed alteration.” Does this refer only refer to common property or any alteration within the lot and if so how far does it go? For example I would not expect this would apply to some simple shelving but what about new built-in wardrobes or new bathrooms and kitchens?

Are there any publications that provide assistance in this area?
