Waiver of Covenant Restriction

Our covenants basically prohibit and structure from being placed on a property. When we took over from the builder, we (the Design Review Board)made a decision to take any action regarding children play equipment. Swing set, trampolines, playhouses. Now we have deteriorating equipment throughout the community. Frankly, we can deal with that. My question is, can we give a waiver or take no action regarding play equipment but place a time limit on how long it can remain on the property. Like 10 years, until the children are 18 or must be removed when the home is sold.
It certainly makes no sense to not allow a swing set, but the covenants say no structure of any kind. How do we allow it and still get rid of unused equipment.

I gave my suggestion in the other post, but LetA makes some good points. read them both and then figure out what you want to do

I'd be very careful about establishing any policy or rule that requires an owner to do something (like take down a swingset) before selling. Those restrictions should be in the CC&Rs because generally you lose any power over an owner once they sell. An owner could ignore whatever they signed and the new owner wouldn't be bound by it (unless it's in the CC&Rs). Owners can fly under the radar and sell their home before anyone else knows what's happening. Of course, if there are pre-sale conditions (such as a Certificate of Approval) that must be obtained before closing, you could make the removal a condition of issuing that certificate.

Side agreements between an owner and an association aren't generally enforceable against a subsequent owner unless the CC&Rs provide a way to do it.
