Rehabilitating your older home is rewarding in many ways, and with the
Property Tax Assessment Freeze homeowners may be eligible for a financial
incentive that can make the work even more attractive. The program
can freeze the assessed value of historic owner-occupied, principal residences
for a period of 8 years, followed by a four-year period during which the
property’s assessed value steps up to an amount based upon its current
market value. This results in 12 years of reduced property taxes.
This program is administered free of charge as a benefit to Illinois
property owners interested in rehabilitating their historic homes.
The Property Tax Assessment Freeze Program benefits both the owner-occupant
and the community by:
- Rewarding owner-occupants for sensitively reinvesting in their homes
- Increasing the value of the rehabilitated property;
- Strengthening neighborhoods and housing within a community
- Encouraging landmark protection through the promotion, recognition,
and designation of historic structures;
If a rehabilitation meets all four provisions described below, the Illinois
Historic Preservation Agency (IHPA) will issue a Certificate of Rehabilitation
for the property. This Certificate allows your assessor to implement
the assessment freeze for your property. To qualify for the Property
Tax Assessment Freeze, a property must:
- Be owner-occupied housing and the principal residence of the
- Single-family houses
- Residential buildings with up to six units as long as the building
owner resides in one of the units
- condominium buildings
- Be a registered historic building. For this
program, a historic building is:
- individually listed on the National Register of Historic Places
in any community in Illinois, or
- a contributing property within a National Register Historic District
in any community in Illinois, or
- individually listed on the Illinois Register of Historic Places
in any community in Illinois, or
- designated as an individual local landmark in a community that has
an approved preservation ordinance, or
- a contributing property within a local historic district in a community
that has an approved preservation ordinance

Opt Out Provision
Any taxing district may “opt out” of the Property Tax Assessment
Freeze Program by notifying the assessor and the county clerk at the beginning
of each calendar year. The Property Tax Assessment Freeze will not
apply then to taxes levied by that taxing district. To determine
whether any taxing districts in your area have opted out, contact your
assessor or county clerk. Properties that have already received
Certificates, or where rehabilitation has already begun, will not be affected
by a taxing district's “opt out.”
