Which of the following scenarios might require a variance?

A variance is a request to deviate from the established zoning regulations or building codes, typically due to unique site conditions or practical difficulties that prevent a property owner from complying with standard requirements.

In the scenario of widening a driveway in a setback area, this is significant because setbacks are designated buffers that dictate how far structures or alterations must be from property lines. If the proposed driveway expansion encroaches into this setback area, it typically would not comply with zoning laws. The property owner would need to apply for a variance to request permission to deviate from this requirement, demonstrating that strict compliance would cause undue hardship.

The other scenarios involve actions that fall within the established regulations. Building a fence within the allowed height complies with the zoning requirements, as does constructing a shed on compliant land, and painting a house a different color does not generally constitute a zoning issue that would require a variance. These actions adhere to their respective codes and regulations, making them exempt from the need for a variance.
