Florida Impact Fee Estimator

Estimate total development impact fees in Florida based on land use type, unit count, and county. Fees cover roads, schools, parks, water/sewer, and fire/EMS infrastructure.

Formula

Total Impact Fee = Σ (Fee Category Rate per Unit × Number of Units)

Where fee categories are:

  • Transportation Fee — based on trip generation rates × cost per trip × credit for existing infrastructure
  • School Impact Fee — based on student generation rate × cost per student station × credit ratio
  • Parks & Recreation Fee — based on persons per unit × acres per person × land/improvement cost
  • Water & Sewer Fee — based on equivalent residential connections (ERCs) × system capacity cost
  • Fire & EMS Fee — based on call generation rate × cost per call × facility/equipment cost

Each county calculates fees using the rational nexus methodology required under Florida Statute §163.31801, ensuring fees are proportional to the infrastructure demand created by new development.
