What could prevent Jenna from having a home business despite local zoning allowing it?

In this situation, the chosen answer highlights the principle that while local zoning laws may permit a home business, there can be other regulations that are even more stringent. These can take precedence over local zoning regulations. Various entities or regulations can impose additional limitations on property use, such as local ordinances, state laws, or restrictions imposed by neighborhood associations.

When considering home businesses, it's especially important to recognize that there could be regulations that are designed to maintain the character of a community, protect property values, or limit disturbances to neighbors. Such regulations can come in many forms, and their potential to restrict business operations illustrates the layered nature of property laws and rights.

For instance, deed restrictions and restrictive covenants can also prohibit certain activities, such as operating a business from home, but the concept of "any more restrictive regulation" encompasses a wider range and captures the essence that even if zoning allows, anything more limiting can overrule that allowance. Therefore, if Jenna encounters a situation where a more restrictive entity or regulation exists, it could indeed prevent her from having a home business, even when local zoning permits it.
