The Approval Path: From Land Option to Switch-On

You'll be able to

  • List the approvals a data center needs in roughly the order they happen
  • Name the body that decides each step and the Idaho statute or rule behind it
  • Read a project timeline and find the long pole, usually the utility
  • Spot the incentive clocks that start running at the building permit or certificate of occupancy

A data center does not get one approval. It gets a dozen, from different bodies, on different clocks, under different laws. The county commission votes on zoning. The state utility commission rules on the power contract. The state environmental agency permits the generators. The Tax Commission certifies the sales tax break. A city council may vote on annexation and a water contract. Most residents only hear about the zoning hearing, and by then several of the other tracks may be months along.

The site selection lesson in the Data Centers module gave a five-year sketch. This lesson takes that sketch apart, step by step, with the Idaho law behind each piece.

The steps, in roughly the order they happen

Order varies. Some steps run at the same time, and the utility step usually starts first because power decides whether the project happens at all.

  1. Site search and land option. A developer or site consultant scouts parcels, often in several states at once, and pays landowners for options. An option costs a fraction of the price and lets the buyer walk away. Sometimes a short memorandum of option gets recorded with the county recorder; often nothing is recorded until the sale closes.
  2. Code names, LLCs and NDAs. The project gets a name like "Project Tamarack," a special purpose LLC holds the option, and economic development staff sign confidentiality agreements. Lesson 8 covers what Idaho's records law does to those agreements.
  3. Utility load request. The developer asks the utility how many megawatts it can have and when. The utility runs load and system studies. This is the first serious paper trail, though most of it stays inside the utility until a contract is filed.
  4. Annexation, if city services are wanted. In Idaho, Idaho Code 50-222 requires published notice and first-class mail to each landowner at least 28 days before the first hearing, separate hearings before the planning and zoning commission and the council, and a written annexation plan covering services, taxes and proposed zoning. Zoning is decided with the annexation.
  5. Rezone, conditional use permit or text amendment. Lesson 2 covers which one applies. Idaho Code 67-6511 and 67-6512 require mailed notice to owners within 300 feet, posting on the site a week ahead and published notice before the hearing.
  6. Development agreement. Under Idaho Code 67-6511A, a board can require a written commitment as a condition of a rezone. It is recorded, it binds later owners, and if its conditions fail, the board can terminate it and reverse the zoning after notice and a hearing.
  7. Tax incentive applications. The state sales tax exemption (Idaho Code 63-3622VV) is claimed by certifying to the Tax Commission. The large-investment property tax exemption (63-4502) has a qualifying period that starts with a building permit. A county exemption under 63-602NN needs a public meeting. Lesson 6 covers all three.
  8. Utility contract and commission review. A special contract or large-load tariff filing goes to the Idaho Public Utilities Commission as a numbered case. Lesson 4 covers what to read in it.
  9. Water. A will-serve letter and supply contract from a city, or a water right permit or transfer from the Idaho Department of Water Resources (IDWR). Since July 1, 2026, Idaho Code 42-252 bars a new data center from using water for cooling as a consumptive use unless a municipal, water district, or water and sewer district system supplies it. Lesson 5.
  10. Air permit for backup generators. A large diesel generator fleet usually needs a permit to construct from Idaho DEQ under IDAPA 58.01.01, Sections 200 to 227, before construction.
  11. Building permits and inspections. Usually ministerial: if the plans meet the codes and the zoning, the permit issues. The fights happen earlier.
  12. Certificate of occupancy and phased operation. Big campuses open one building at a time. The certificate of occupancy matters for incentives, as the example below shows.

That last row deserves a closer look. IDAPA 58.01.01.209.01.c says an opportunity for public comment is provided on all permit to construct applications, and that comment is provided for new major facilities, projects affecting a Class I area, applications DEQ decides need it, and "any application upon which the applicant or public so requests." The comment period runs 30 days after notice is published. So a resident who asks can get a comment period on a generator permit that might otherwise issue quietly.

Illustrative schedule for the invented Project Tamarack. Real projects vary, but the utility track is usually the longest.

Example: finding the long pole in Project Tamarack

Invented Brindle County, population 24,000. A developer options 320 acres in month 0 for "Project Tamarack," a 200 MW first phase. Here is the schedule the developer gives the county, and what it means once you add it up.

  • Utility studies: month 2 to month 14, so 12 months.
  • Special contract filed at the state commission in month 14. Idaho's two most recent very large contracts each took about 17 months from filing to final order: Brisbie LLC (IPC-E-21-42, filed December 22, 2021, Final Order No. 35777 on May 11, 2023) and Micron (IPC-E-24-44, filed December 6, 2024, Order No. 37039 on May 8, 2026). Use 17 months: 14 + 17 = month 31.
  • The utility will not order a $90 million substation until the contract is approved. Substation and transmission work: 24 months. 31 + 24 = month 55.
  • Building permit in month 24. Shell construction starts month 25 and takes 18 months: 25 + 18 = month 43.
  • Idle time: 55 minus 43 = 12 months of finished building with no grid power.

Now the incentive clocks.

  • Idaho Code 63-4502: the 84-month qualifying period starts when a building permit issues for a permanent structure. 24 + 84 = month 108 to reach $1 billion of investment in the county.
  • Idaho Code 63-3622VV: $250 million within five years after construction begins. 25 + 60 = month 85.
  • Jobs: 30 new jobs within two calendar years after commencement of operations, which the statute defines as the date a certificate of occupancy issues. If the county issues the certificate at month 43, the job deadline falls around month 67, though the servers only got power at month 55.

So a county deciding when to issue a certificate of occupancy is also, quietly, setting the start of a state incentive clock. Anyone following the project can ask the building department and the company which date they expect to count.

What gets decided where

The zoning hearing feels like the main event because it is the one with a microphone for the public. It decides land use: whether this use belongs on this parcel, with what conditions. It does not decide electric rates, which belong to the PUC. It does not decide the generator emission limits, which belong to DEQ, or the water right, which belongs to IDWR. A county commission that promises residents it will "make sure rates don't go up" is promising something outside its power, unless it means it will intervene at the PUC, which counties and cities can do.

The reverse also happens. A resident testifies at a zoning hearing about electric rates and gets told it is off topic. That is accurate. The right venue is the PUC case, and the resident should be told its number.

Common mix-ups

  • Claim: Once the land is rezoned, the project is locked in. What the evidence shows: In Idaho, a rezone tied to a development agreement can be reversed under Idaho Code 67-6511A if the conditions fail. And the project still needs its utility contract, air permit and water.
  • Claim: No application on file means nothing is happening. What the evidence shows: Utility studies, land options and incentive talks often run for a year before a land-use application appears.
  • Claim: The county decides everything about the project. What the evidence shows: Power contracts, air permits, water rights and the state sales tax exemption are decided by state bodies. The county decides land use and its own tax exemption.

Reporting angle

  • Build a one-page tracker with a row for each step in the table above: agency, case or file number, date filed, next decision date.
  • Ask the developer for its full schedule, including the utility in-service date. Compare it with the building schedule and look for idle time.
  • Ask DEQ whether a permit to construct application exists for the parcel or LLC, and request a comment period in writing if you want one.
  • Ask the building department when a certificate of occupancy is expected and whether it will be partial or full.
  • Check the PUC new-case list weekly for the utility's code plus "special contract" or "Schedule."
