What new construction actually pays, and who is allowed to charge it

Impact fees, tap fees, plan review, capacity charges, school fees, in-lieu payments. They arrive from five different bodies under three different bodies of law, and no single desk knows all of them. This is the map.

Answer four things and get the list of every body that can bill this project, what each one is allowed to charge for, and the rights your state's law gives you before you pay.

Why this site refuses to quote you a number

Every other page on this subject either lists fees for a handful of big cities, or averages them into a figure no builder can put in a pro forma. Both go stale within a year and neither survives contact with a special district nobody mentioned.

What can be stated precisely and kept current is the legal skeleton: which states authorize impact fees and under what statute, which categories of facility each act permits, when the fee must be collected, how long the jurisdiction has to spend it before owing you a refund, what credits you are entitled to, and how far the schedule locks in once your plat is approved. That skeleton tells you what questions to ask, which is what actually gets you an accurate budget.

Then this guide walks you through getting the real number for your parcel in about two hours.

Every state

Green means a general enabling act, amber means partial or home rule authority, grey means no act was identified.

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.
