To determine the enforceability of restrictive covenants, courts look for the original intent behind the covenant and any substantial changes in conditions that may have nullified its purpose. If radical changes have not occurred within the restricted area itself to undermine the covenant’s initial objectives, it is likely to remain enforceable.
For example: A subdivision with a restrictive covenant for single-family homes remains largely unchanged despite a nearby commercial boom. Since the essential residential character is preserved, the covenant remains enforceable.
