Some properties are located in areas under county jurisdiction. They may carry the name of an adjacent city for mailing / identification purposes but not be within the city’s boundaries.
While property outside a city’s boundaries may mean little or no restrictions regarding property use, and carry less taxes, the city identified in the property's address is not necessarily bound to provide amenities, police or fire protection.
If access to these services are important to you, be sure you understand if the property under consideration is within the city limits.
