What could signify the existence of a covenant in a neighborhood?

A deed restriction requiring certain building standards is a clear indication of the presence of a covenant within a neighborhood. Covenants are legally binding agreements or promises regarding the use of the property, often detailed in the property's deed. These restrictions can dictate various aspects of property ownership, including the types of buildings allowed, architectural styles, landscaping requirements, and maintenance of property values within the community.

When a deed outlines specific building standards that all property owners within a particular neighborhood must adhere to, it serves as a form of covenant aimed at ensuring uniformity and preserving the aesthetic and functional aspects of the community. This can enhance property values and improve the overall environment where people live.

In contrast, the other options do not necessarily indicate the existence of a covenant. For instance, surveys indicate property lines but do not address any agreements regarding how the property can or cannot be used. Public votes on zoning laws pertain to community planning and regulations set by local government but do not involve individual property use agreements. Similarly, city ordinances govern land use at a broader level as determined by municipal authorities and do not specifically limit properties based on private agreements between landowners.
