OP submit a motion to the EC for the upcomming EC meeting asking that all owners that have have made alterations without a relevant byalw must within 2 weeks show that they intend to submit a relevant bylaw within the following 4 weeks covering said alterations.
Any owner that dosn’t comply and has made alterations the EC will have a bylaw drawn up at the owners cost and voted on at the next general meeting.
I have been informed (from another forum) that the EC can get a bylaw written to address these situations and bill the offending owner for the cost of having the bylaw written.
This seems to me to be an excellect soloution to the strata being lumbered with ongoing maintenace of illegal work.
If they decline to do this I consider that you have every reason to go ahead with your alterations without having a bylaw written.
If they agree to this just wait untill the bylaws are submitted and then you submit another bylaw (coppied from one of your 2 similar alterations) adapted for your unit.
