# Data center laws and local rules: Know every law, moratorium, tax break and power tariff that decides where data centers get built.

Canonical page: https://spezia.ai/tools/legislation

Every U.S. federal and state bill and law, county and city ordinance, moratorium, zoning rule, tax incentive, large-load power tariff and water rule that names data centers. Each one says what it does in plain words, where it stands, its dates, the states, counties and tracked projects it covers, and links to its official text. Built for developers and site teams, and for the contractors, suppliers and lenders whose jobs move with each vote.

## What you get

- **Every rule in one place.** Federal and state bills and laws, county and city ordinances, moratoriums, tax incentives, power tariffs and water rules, each with what it does in plain words.
- **Where each one stands.** Proposed, moving, adopted or in force, with the dates and the quote or official record behind the status, so a vote is never a surprise.
- **Tied to the projects it covers.** County, city and utility rules are matched to the tracked projects inside them, and each project file lists the rules that apply to it.

## How it works

## Questions

### Where do the measures come from?

The Federal Register and the U.S. government's own bill status files, read directly; state bills on data centers from the legislature records kept by LegiScan (bill data CC BY 4.0) and Open States; and a weekly search of legislatures, county and city agendas and codes, utility commissions and the press. A measure is kept only when a quote from its document says what it does, and its status and dates only when a quote or an official record states them.

### Is every measure linked to its official text?

Each week Spezia looks for the official page of every live measure: the legislature, the county or city code, the commission docket or the Federal Register. When none is found yet, the page says so and links the report it came from.

### Is this legal advice?

No. It is a sourced record of what each measure says and where it stands. Read the official text, and ask counsel before acting on it.

### Which plan includes it?

Ultra, with the rest of the build-out. A free account opens the whole build-out 3 days a month.
