In a real estate context, a 'covenent' is usually a restriction that governs the use of land, typoically imposed by a local authority that embraces many similar parcels. Covenants 'go with the land', regardless of the owner. They are typically used to impose a spectrum of use, engineering, or architectural controls --- for instance, to limit house size, prevent your neighbor from setting up a mobile home permanently in his driveway, accumlating junk in his front yard., or keeping smelly or noisy farm animals..
