City extends deadline for property owners to appeal proposed assessments until February 23

The City of Detroit has extended the deadline for property owners to challenge their proposed 2019 property assessments by more than one week to February 23rd.  The original deadline had been February 15th, however a delay in delivery of the notices prompted city officials to extend the deadline.

“Assessed property values went up this year in 90% of Detroit’s neighborhoods, which is great news, and we want to make sure that all property owners have sufficient time to appeal their assessments in case they have additional information that could affect our proposed assessments,” said Chief Financial Officer Dave Massaron.

Last month, officials announced that residential property values in Detroit increased by an average of 12% over the previous year, with several neighborhoods seeing gains of more than 20 percent. However, while property values have increases sharply, property taxes for most will not.  Under state law, the annual increase in property taxes is capped at the Consumer Price Index or the annual rate of inflation (1.02%), whichever is less.  That cap is lifted only when a property transfers.  At that time, the taxable amount will adjust to the State Equalized Value the year following the transfer.

The new values are based on two years of market data, which included nearly 11,000 valid arms-length transactions, a 16% increase in activity from the last year’s assessment.

Notices were mailed out last week to the city’s 270,000 residential and industrial property owners, advising them of their proposed assessments for 2019. These are not tax bills. Actual bills will be mailed out in July and payments are due August 15th.  Commercial Property Owners, due to the completion of the commercial reappraisal, will receive their notice later.


How to appeal your propose assessment

All property owners have the right under state law to appeal their proposed assessment. Additionally, the City of Detroit offers property owners an informal opportunity to appeal their property value. The Assessors Review appeal process will take place February 23rd in Room 804 of the Coleman A. Young Municipal Center, 2 Woodward Ave., Detroit, MI. The March Board of Review, the second step in the review process, begins March 6th and ends March 23rd in Room 1208 of the Coleman A. Young Municipal Center.  Anyone with questions or wishing to challenge their assessments can email the Assessor’s office at [email protected].

Residential Property Owners must begin the appeals process at the Assessors Review. Commercial, Industrial, and Personal Property owners may, if they chose, proceed directly to the Michigan Tax Tribunal. The deadline to appeal directly to the Michigan Tax Tribunal is May 31.


Help Available

The City of Detroit is taking a proactive approach to helping homeowners avoid the threat of tax foreclosure.  The Assessor’s Office will be mailing applications for the Homeowners Property Tax Assistance Program to all Detroiters who are delinquent on their 2018 property taxes to determine whether they qualify for tax relief. 

Detroit’s property tax exemption for low-income households can reduce or eliminate property taxes on homes, depending on the occupants’ income levels and the number of people living in the home.

Homeowners who have questions about the Homeowners Property Tax Assistance Program or wish to receive an application may call the Office of the Assessor at 313-224-3035 or the Detroit Board of Review at 313-628-0723. The application for the Homeowners Property Tax Assistance Program also is available on the city’s website at
