  • Roadway Development Impact Fee

    constructionArizona State Statutes authorize counties to collect development impact fees to fund infrastructure necessitated by growth. The Roadway Development Impact Fee is assessed for new or proposed developments to help pay for the arterial roadway capacity needs created by new development. Monies collected must be used to increase roadway traffic capacity (i.e. widening) on roadways specified for improvements. The fees are charged in ten benefit areas. Fees can not be used for roadway maintenance or to improve local roads. The fee is assessed at the time of development.

    For a current fee schedule, please scroll to the bottom of the page.  Fees are listed for different types of developments. 

    Impact Fee Update 2020
    Pima County has updated the impact fee program in compliance with A.R.S. §11-1102.  On August 17, 2020 the Board of Supervisors approved a new ordinance which will become effective on January 1, 2021.  The Board also approved a gradual phase-in of the new rates in part, due to the economic uncertainty of COVID-19. The table below shows existing rates and the phased-in rates over the next three years.

    Frequently Asked Questions

    Will all roads be widened and maintained with the fee?

    No. By state law, impact fees can only be used for projects identified in the improvements plan.  Fees cannot be used for road maintenance. 

    How are the road projects to be funded with impact fees determined?

    A wide variety of information is gathered and analyzed including traffic patterns, traffic volumes, anticipated growth and changes to the infrastructure. Planners and engineers then recommend the road projects that will provide the most benefit to the greatest number of households in a benefit area. The Pima County Board of Supervisors then decides which road projects to fund with impact fees.

    What are the benefit area boundaries and the road projects to be funded with impact fees?

    Impact fee-eligible road projects and benefit area maps are shown on the "Benefit Area Maps" tab.

    Who pays the roadway development fee?

    All new development, including both residential and non-residential construction in unincorporated Pima County is assessed a fee. In addition to site-built homes, this includes manufactured homes, travel trailers, trailers, mobile homes, and recreational vehicles plus non-residential development. Churches and schools are currently exempted from impact fees, but new schools will be assessed a fee after January 1, 2021.

    When and how was the fee implemented?

    The Pima County Board of Supervisors originally implemented the roadway development fees on November 18, 1996 with Pima County Ordinance 1996-09 and 1996-73. The most current ordinance regarding impact fees is 2009-95.

    When is the fee paid?

    Per Arizona Revised Statutes 11-1102 et seq and Pima County Ordinance 2009-95, roadway development impact fees are assessed and paid at the time the building permit is issued.
