How Much Are Impact Fees in Florida by County?

Impact fees in Florida by county run from about $10,000 to more than $37,000 for a single-family home, with the exact number driven by where you build, how large the home is, and which subzone of the county it sits in. These one-time charges are collected by local governments when a building permit is issued, and they pay for the roads, schools, parks, fire stations, and law enforcement facilities that new construction pushes local governments to build. The gap between the cheapest and most expensive counties is wide enough that the same house plan can carry a fee bill nearly four times larger in one jurisdiction than in another.

What Florida Counties Actually Charge

The clearest way to see the range is to compare published fee schedules for a single-family detached home.

Miami-Dade County sits at the low end. Total impact fees for a single-family detached home run about $9,275 to $10,625 depending on the context zone.¹

Orange County lands in the middle-upper range. As of January 2026, transportation fees alone for a mid-sized detached home of 2,001 to 3,500 square feet run $11,617 in urban areas and $16,339 in rural areas. Layer on school fees of $9,513 to $12,015 depending on home size, parks at $2,338, law enforcement at $644, and fire at $446, and a typical suburban home totals roughly $25,000 to $32,000.²

Osceola County is the highest in this sample. Combined fees for a single-family home reach roughly $36,000 to $37,700, driven by mobility fees above $20,000 and school fees of $12,923.³

St. Johns County scales sharply by home size. A unit under 800 square feet pays $11,074; a home over 5,001 square feet owes $30,332.⁴

Polk County falls in the middle, with totals of about $22,000 to $25,000 for a single-family detached home depending on the transportation district. The education fee alone is $14,338.⁵

Commercial projects use a different math entirely: fees are scaled by gross square footage and land use classification, and a high-traffic retail center can carry transportation fees several times higher per square foot than a professional office building on the same lot.

What Categories Make Up the Bill

A single impact fee invoice is really the sum of several separate charges, each tied to a specific type of infrastructure. Which category dominates depends on the county.

Transportation or mobility is almost always the largest line. It exceeds $14,000 in suburban Orange County and tops $21,000 in Osceola.²
Schools are the second-largest category in most counties, typically $8,800 to $14,300 per home in the jurisdictions above.
Parks and recreation charges usually run $1,800 to $2,400.
Fire and emergency services fees are modest by comparison, generally $150 to $780 per home.
Law enforcement fees typically fall between $500 and $650.
Water and sewer capital charges may be assessed separately from the standard impact fee schedule. Orange County, for instance, handles water and sewer through its utilities department rather than the impact fee schedule.²

Why the Numbers Vary So Much

Growth pressure is the biggest factor. Counties absorbing rapid population expansion need new roads, schools, and fire stations built from the ground up, so per-unit charges are high. Osceola County sits on the Orlando growth corridor and needs substantial new capacity. Miami-Dade is largely built out, so the marginal infrastructure demand from a new home is smaller and fees are lower.

Home size drives residential fees within a single county. Larger homes are assumed to house more people, generate more vehicle trips, and produce more school-aged children. St. Johns County makes this the primary variable, with the largest homes owing nearly three times what the smallest units owe.⁴

Subzones within a county matter too. Orange County charges different transportation rates depending on whether the site is classified as urban, suburban, or rural, with rural rates running roughly 40% higher than urban rates for the same home size.² Polk County operates three distinct transportation districts with separate rate schedules.⁵ Whether the property is in an incorporated city or the unincorporated portion of the county can also change which schedule applies.

How to Estimate Fees for Your Project

Start by pinning down the exact jurisdiction. City limits and county lines change which schedule governs your parcel, and the two can differ significantly even a few blocks apart.

Then find the land use code that matches your project. Residential codes usually turn on unit type and often on square footage tiers. Commercial codes turn on the specific business classification. The local building department publishes a schedule linking each code to a dollar amount per unit or per square foot. Several counties, including Orange and Hillsborough, offer online calculators that produce a preliminary total from your project details.

For a residential estimate, you need the number of dwelling units and the square footage of each. For commercial, you need gross square footage and the use classification. Apply the rates category by category, sum them, and you have a working budget number. Build in some cushion for scheduled rate updates during your planning window.

Statutory Caps on Rate Increases

The Florida Impact Fee Act, Section 163.31801 of the Florida Statutes, limits how fast local governments can raise these charges, which puts a ceiling on the surprises you can face between planning and permitting. No single increase can exceed 50% of the current rate. A fee cannot be raised more than once every four years. Increases of up to 25% must be phased in over two equal annual installments; increases between 25% and 50% must be phased in over four. Retroactive increases are barred, and local governments must give at least 90 days’ notice before a new or increased fee takes effect.⁶

Credits and Waivers That Can Lower the Bill

Developers who build public infrastructure or dedicate land as part of a project can offset their impact fee obligation. Florida law requires local governments to apply these credits dollar-for-dollar at fair market value against fees in the same category of infrastructure.⁷ A road you build gets credited against transportation fees, not school fees. If the local government doesn’t charge a fee for the category you contributed to, you get no credit.

To capture the credit, you generally need engineer-certified cost estimates, as-built drawings, and a recorded deed or easement transferring the improvements to the local government, all documented before you pull building permits. A written credit agreement negotiated early prevents disputes at issuance.

Affordable housing developments can be granted waivers or reductions under Section 420.9071 of the Florida Statutes, but this is permissive, not mandatory. A county or city may offer the exception; state law does not require it, and if a jurisdiction does grant a waiver, it is not required to backfill the lost revenue from other sources.⁷ Confirm the local policy before assuming any reduction applies.

When Payment Is Due

State law prohibits collection of impact fees before the building permit is issued.⁷ In practice, most jurisdictions require payment in full before the permit is issued. Miami-Dade County, for example, will not issue any building permit until all required impact fees are paid.⁸

Some local ordinances allow deferral to the certificate of occupancy stage, but this usually requires a separate agreement. Online portals typically accept electronic check or credit card; in-person payment usually requires certified funds. Keep the receipt. It is a prerequisite for final permit approval.

Challenging a Fee

If you believe a fee is miscalculated or unjustified, Florida law puts the burden of proof on the local government, not the developer. The government must show by a preponderance of the evidence that the fee meets the requirements of the Florida Impact Fee Act.⁷ Challenges most often succeed when the underlying fee study is outdated or fails to reflect local conditions, or when fee revenue is spent in ways disconnected from the area where the fees were collected.
