Look at this neighborhood as a map of permitted uses. Zoning divides land into districts and sets public rules for use and development. One district may allow homes. Another may allow commercial uses. Development standards can also control matters such as setbacks, height, or density. The actual ordinance supplies the details. Separate public rules from private restrictions. Zoning comes from government authority. Covenants, conditions, and restrictions are private controls. A variance is specific authorized relief, not an automatic change to the whole zoning district. Quick check: are setbacks commonly an example of zoning controls? Yes. Setbacks regulate development under public authority.
