Impact fees are charges assessed for the impact that is created by new development on Hillsborough County parks, schools, and fire systems. This may also apply to new construction on a vacant property or new construction and remodeling of an existing structure if there will be an increase in useable area. Transportation/ROW impact fees have been replaced by a mobility fee.
Mobility/Impact Fees are assessed prior to issuance of a building permit, or equivalent. The assessment will remain valid for the life of the permit.
If you allow your permit to expire, Mobility/Impact will be reassessed at the current rates and updated when the permit is reissued. These rates may be higher than those initially assessed. To guard against this potential scenario, please ensure your permit remains valid and active until your project is complete.
Mobility and Park Impact Fees
On June 16, 2021, The Board of County Commissioners (BOCC) restored changes to the County's mobility fee and impact fee ordinances originally approved on May 20, 2020.
