In 2001 the Community Revitalization Financing (CRF) Act was created.  It authorized cities, towns, counties, and port districts to create a tax increment area and finance public improvements within the area by using increased revenues from local property taxes generated within the area.
 
An increment area cannot be created without the approval of the local government imposing at least 75 percent of the regular property taxes within the area.  The incremental property taxes under this program are calculated on 75 percent of any increase in the assessed value in the increment area.  Any fire protection district with geographic boundaries in the increment area must agree to participate in the project in order for it to proceed.  The CRF Act does not include any state contribution.
 
In 2020 the Legislature enacted House Bill 2497 expanding the use of CRF monies.  The purchasing, rehabilitating, retrofitting for energy efficiency, and constructing housing for the purpose of creating or preserving permanently affordable housing was added to the public improvement costs authorized for the CRF Act.
 
"Permanently affordable housing" is defined as housing, regardless of ownership, for which there is a legally binding, recorded document in effect that limits the price at which the owner may sell.  The type of documents may include affordability covenants, deed restrictions, and community land trust leases.

The definition of "public improvements" for CRF includes permanently affordable housing.
