Impact Fee Documents

​​​There are quite a few documents which govern the assessment and collection of Development Impact Fees.

State Legislation

First, there's the State enabling legislation, otherwise known as Arizona Revised Statutes, Title 9, Chapter 4, Article 6.2, otherwise referred to as A.R.S. §9-463.05. To see this legislation, please use the following link to the Arizona State Legislature website:

Annual Impact Fee Reports

As of January 1, 2012, A.R.S. §9-463.05, Section O, requires that the Annual Impact Fee Report be filed with the City Clerk, and posted on a municipality's website within 90 days following the end of the fiscal year (June 30).

Biennial Audit Reports

As of January 1, 2012, A.R.S. 9-463.05, Section G.2 requires that the findings of the biennial certified audit of land use assumptions, infrastructure improvements plan and development fees are posted on a municipality's website, and that a public hearing is conducted within 60 days of the release of the audit to the public.

City of Phoenix Documents

Several documents create the framework for the assessment and collection of Development Impact Fees in the city of Phoenix. First, the Development Impact Fee Ordinance (Chapter 29 of the Phoenix Code of Ordinances) establishes the procedures and standards for the creation of the Development Impact Fee Program.  To see this ordinance, use the following link to, which publishes the Phoenix Code of Ordinances online:

The research and analysis used to calculate and establish impact fees are found in the Infrastructure Financing Plan (IFP) for the city of Phoenix. The most recent IFP was approved on January 21, 2015 and became effective April 6, 2015. The proposed 1st Amendment to IFP Chapter 3 Fire Protection is now available for review.

Proposed minor amendment to the Infrastructure Financing Plan and Chapter 29 of the City Code:

Water Resource Acquisition (WRA) Fees are managed by the Water Services Department.  Updated WRA fees were approved by Council at the same time as Impact Fees, and became effective on April 6, 2015. The Water Resource Acquisition (WRA) fee has a separate report and infrastructure financing plan.

The Street Transportation Department completed an Impact Fee Transportation Study to support the Major Arterials Infrastructure Improvement Plan (IIP) and impact fee updates that were ultimately adopted by Council through the Infrastructure Financing Plan (IFP).

For information regarding capital facilities funded by discontinued Impact Fees, please see the previously approved 2012 Infrastructure Financing Plan.

**Per A.R.S. 9-463.05, commercial, industrial, or multifamily development that obtains final site plan approval, or platted residential development that obtains the first building permit within 24 months preceding the effective date of a modified development fee will be charged the lesser of 1) existing impact fees, or 2) revised impact fees, for a period of 24 months following the final plat or site plan approval.
