Township of Mendham

---

The Morris County Board of Taxation and the New Jersey Division of Taxation have authorized the Township of Mendham to perform a reassessment for the 2026 tax year as part of the reassessment program that has been implemented within the Township.  This program will ensure uniform and equitable assessments throughout the municipality, account for the recent changes in the real estate market and significantly reduce the costly tax appeals experienced in the past.  The Township has contracted Associated Appraisal Group, Inc. to assist in conducting the Reassessment Program.

As a requirement of the annual reassessment program, an inspection of the interior of 25% of the Township’s properties must be attempted.  The purpose of this inspection is to maintain accurate and current data regarding your property.  Associated Appraisal Group will be supplied with all current Property Record Cards (PRC’s) maintained by the Assessor’s Office and any recent construction permits issued by the Building Department.  Associated Appraisal Group representatives will carry photo identification and their names will be registered with the Police Department and the Township Clerk’s office.  Please do not allow anyone to enter your home without proper identification.  You will be requested to sign the field form used by the representative to acknowledge when an interior inspection is made.  Please advise the occupants of any rental units you may own so they are prepared for the inspection.   

Regardless of when a property is visited during this program, the new property values will be determined based on their estimated market value as of October 1, 2026 (the statutory date required by law).  It is important to note that while only 25% of properties are being inspected each year; all properties in town will be valued.  All property owners will be notified by mail of their proposed assessed values and will have an opportunity to question/contest the values. 

Any inquiries with respect to the inspection and/or valuation procedure should be directed to Appraisal Systems, Inc. at (201) 493-8530.

Thank you for your cooperation during the reassessment process.
