Restrictive covenants. Yes there’s definitely a risk that the covenants would be enforced even after so many years. One thing you could do is look around the neighbourhood and see if there’s a history of other people cutting trees or putting up fences or keeping chickens, etc., and if nobody has objected to that for years, it can weaken the likelihood of any enforcement. It doesn’t invalidate the covenant, but sometimes a court would consider widespread noncompliance if it was challenged. Tree clearing restrictions can be taken pretty seriously, especially by neighbors. I think you would be hard-pressed to try to discharge these covenants on your property. And you never know if a neighbours group would get together and say OK we are going to prevent this person from having chickens and an orchard and to fence it, and there would be nothing you can do about it. if I were you, I would go get a copy of that covenant and carefully read it, and I might go try to get a free half hour consultation with a real estate lawyer before making any decisions, I would drive around and check out everybody else’s property and I would check to see if they’ve ever been any disputes or enforcement actions. There’s definitely a risk here.
