Building restrictions and restrictions relating to land-use that are enforceable in equity by and between landlords. Covenants pertaining to land-use may be enforceable in equity either when the equitable enforcement is supplementary to the legal remedies at law for breach of contract or the invasion of a property right or when the restriction is cognizable only in equity. Burby, Real Property 100 (1965). For a covenant to be valid at law, as to remote grantees of the affected property, there must exist privity of estate between covenator andcovenantee, but such a relationship is not necessary to create an enforceable equitable servitude so long as the subsequent grantee has either actual or constructive notice of the covenant. Id. At 98, 108.
Usually equitable servitudes are created as the result of covenants relating to the use of land and embodied in a deed that conveys a possessory estate. The conveyance of a possessory estate in land is not essential to the creation of equitable servitudes; landowners in a specified area may join together in the execution of a document placing restrictions on their land which are enforceable among themselves.
