Impact Fee calculations are set so that each type of land use pays a fair share of the infrastructure required to support development in the city's growth areas. In addition, different areas have unique infrastructure requirements, so the cost of providing the same level of service in each area may vary. This results in different fees for different uses, as well as different fees for different impact fee areas.
The table below indicates the impact fees due at the time a construction permit is issued for a single-family home in each of the nine (9) different impact fee areas within the city of Phoenix. All links within the table are in PDF format.
