Special bylaw for tiling common property

I recently renovated my bathroom and had all walls re-tiled including the boundary bathroom wall which is common property. The wall was only half tiled, however it is now fully tiled from floor to ceiling. I didn’t get permission to do so as I am new to strata living and didn’t realise i had done the wrong thing until after the renos were done. I am now trying to rectify the matter and the creation & registration of a by-law is a costly expense. To avoid having a lawyer draft a special by-law i was after some help with wording or alternatively if anyone had done this previously and could provide wording of their special by-law for tiling common property, that would help immensly!

Thanks
