We are a community of 20 houses and have never had any problems in 8 years. Our Internal Rules stipulate that no tenants can keep dogs. One owner rented his property to a dog owner and the dogs created much unpleasantness due to one dog attacking owners, not biting, just frightening them. That tenant has now gone however the owner wants to let his house to another dog owner. We will vote on changing the rules to enable tenants to keep dogs in January ( AGM,) instigated by that owner. What proportion of votes will he need to have the rule changed? I'm assuming he will require a majority, 51%, is that correct?
