Depends on state and local authority

Impact fee

A one-time charge on new development to pay for its share of capital facilities, calculated from a nexus study.

Who charges it

The city or county, under a state enabling act or home rule power

The trap

The name varies by state. Oregon says system development charge, Arizona says development fee, Tennessee says adequate facilities tax. Same animal.

Thirty statutory citations appear in the national compilation of state enabling acts, though the author counts twenty-nine states, because Maryland's provision reaches only code home rule counties. Texas passed the first general act in 1987 and Oklahoma the most recent in 2011. Nothing new has been enacted since.

Every act limits fees to a proportionate share of the burden new development actually creates, using one of a few standard phrases: proportionate share, reasonable relationship, reasonably attributable, necessitated by and attributable to.

The trend since the mid-2000s has run toward restriction rather than expansion. Wisconsin stripped counties of the power in 2006, Arizona rewrote its act in 2011 to delete several facility categories, and Florida has capped how fast fees may rise since 2021.

Read this before you rely on anything here. Impact Fee Map describes who is legally allowed to charge new construction, for what, and what a fee payer's rights are under state law. It does not publish fee amounts for any city, county or district, and it never will, because no source keeps thirty-nine thousand local schedules current and a stale number is worse than none. This is not legal advice, not a fee quote and not a substitute for the adopted fee schedule of the bodies with jurisdiction over your parcel. Statutes change; verify against the current text and confirm every figure in writing with the agency that will bill you.
