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.
Assumptions & References
- Fee rates reflect 2023–2024 adopted schedules from each county's impact fee ordinance
- Single-family fees are tiered by home size (square footage) as adopted by most Florida counties
- Commercial/retail fees are assessed per 1,000 gross square feet of building area
- Hotel fees are assessed per guest room
- School impact fees apply to residential uses only (per Florida law)
- Water & sewer fees may be charged separately by utility authorities (e.g., JEA, FGUA)
- Municipal impact fees (city-level) are not included — additional fees may apply within city limits
- Florida Statute §163.31801 governs impact fee methodology and caps annual increases at 12.5% per year (25% over 4 years)
