Beauie, for all sorts of reasons from security and privacy you can expect that that any by-law as such would be invalidated quickly when it came before an adjudicator in any jurisdiction. These things need be considered reasonable and on what you say it certainly doesn’t sound like it is and I’ve never heard of another instance of it. If it was me, I’d dig my heals in and just say no. And let whoever wants to enforce it do the work and spend their time in furthering it. Also, I wonder if any lot owner insurance claim would stack up as there would be no forced entry should you try make a claim eventuating from such a visit?
