The restrictive covenant is a device by which property owners can gain some degree of assurance that neighboring property will not be used in an objectionable way. The restrictions are usually reciprocal and negative, common examples being building restrictions, regulations as to use for business, and prohibitions against occupancy by certain races. By private agreement much greater protection can be had than is afforded by zoning ordinances and nuisance doctrines.
