Abstract: The notification subscription service methodology and system provides notice to at least two contact persons when an event occurs that may affect property, or that might involve an individual such as an elderly parent in whom these persons have an interest. Pertinent information about the property or person as well as the contact persons is solicited at the time of subscription. The information is stored in a computer database in a call center. Materials are provided to the subscriber including a yard sign or window decal that has a distinct visual appearance and call center contact information. Nearby neighbors are provided with a card which includes the property address and owner's name and instructions to call the center when an event occurs. This contact by an observer of the event triggers a preferred question protocol and leads to the contacting of the contact persons through preferred contact modes such as cell phone, text, regular phone or e-mail.
