As a result of this process, the Assessor’s Office maintains records which relate to items that can affect a property’s value, including the filing of tax exemptions. Research into inquires regarding ownership, overlay problems, rights of way, riparian rights, and others that occur on a routine basis. The office is also tasked with maintaining a current street address database in order to comply with the E-911 emergency dispatch system.
