CC&Rs (Covenants, Conditions & Restrictions)
A real covenant is a legal obligation imposed in a deed by the seller of a home and or property upon the buyer of the real estate to do or not to do something. Such restrictions frequently "run with the land" and are enforceable on subsequent buyers of the property. Examples might be to maintain a property in a reasonable state of repair, to preserve a sight-line for a neighboring property, not to run a business from a residence, or not to build on certain parts of the property.
Many covenants are very simple and are meant only to protect a neighborhood from homeowners destroying trees or historic things or otherwise directly harming property values. Some can be more specific and strict, outlining everything a homeowner can do to the exterior of their home, including the number of non-familial tenants one may have, acceptable colors to re-paint the home, exactly when holiday decorations are allowed up, automobile placement or repair on property, satellite placement, etc.
