I’ll be doing pretty much this same renovation next year. All cosmetic, but in my case I will be changing bathroom tiles. So I’ll need a by-law, but all the by-law needs to say is that the waterproofing has been done by a qualified person (I provide certification documents) and that I’m responsible for the waterproofing going forward.
I can do the right thing and extend the by-law to cover all the rest of the work to say that I have to use licensed plumbers and electricians. And I can add in the acceptable hours of work and clauses about not damaging common property and letting residents know in advance about noisy work (like removing existing tiles).
I can prepare that by-law myself based on by-laws we already have.
I’ll be submitting the by-law and all documents to the SM with advance notice, and if the Committee decides to drag it’s heels (which it will do because I’m the only one that does anything), then I’ll just start work. If anyone wants to take me to NCAT, they can do so, and I will ask for costs to cover lost rental income. My documents at NCAT will show that I am prepared and following the rules and that I have kept the other owners involved and informed for months in advance.
