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.

    Frequently Asked Questions

    What is the Roadway Development Impact Fee?

    This fee helps to pay for major (arterial) roadway capacity needs created by new development. Monies collected must be used to increase roadway traffic capacity (i.e. widening) on the roads specified for improvements. Fees are charged in seven service areas. Impact fees cannot be used for road maintenance. 

    Will all roads be widened and maintained with the fee?

    No, only a small portion of roads serving new development can be widened due to limited funds. Fees can only be used to fund future roadway capacity needs created by new development and not existing capacity needs that may be the result of prior development. By state law, impact fees cannot be used for road maintenance.

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

    Planners and engineers analyze traffic volumes and patterns, anticipated growth and future roadway needs. Based on this analysis, staff recommends road projects that are most needed to serve new households and developments in a service area. The Board of Supervisors ultimately approves which road projects to fund with impact fees.

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

    The list of Impact Fee Road projects, service areas, and reports are provided on the Pima County Department of Transportation webpage.

    Who pays the roadway development fee?

    Anyone building a new house or business or any developer building a subdivision or other development in unincorporated Pima County pays this fee. The fee applies to all types of residential housing, including site-built homes, manufactured homes, mobile homes, tiny houses, and recreational vehicles. All commercial, retail, industrial and other non-residential development is required to pay the fee except churches, which are exempt.

    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 was adopted on August 17, 2020 with Ordinance 2020-27.

    When is the fee paid?

    Per Arizona Revised Statutes 11-1102 et seq and Pima County Ordinance 2020-27, roadway development impact fees are assessed and paid at the time the building permit is issued.

    Can fee be waived?

    Impact fees may not be waived per state statute, however developers of HUD projects should check with the Community Development Department regarding currently available affordable housing programs.
