Know Your Rights

South Dakota law gives residents real rights in this process. Here they are in plain words, with the law each one comes from.

At Public Meetings

  • Notice of the meeting, with a proposed agenda, must be posted for at least 24 hours in a row before the meeting, at the office and on the website if there is one.
  • Every official meeting must include a time for public comment. Leaders may limit how long people speak, but they may not shut comment out.
  • You may record an open meeting with audio or video, as long as you do it openly and do not disrupt the meeting.
  • If you think the open meetings law was broken, you can file a complaint with the state's attorney for your county, who may send it to the South Dakota Open Meetings Commission.

Do This First

If a Company Applies to Build

A specific project often needs a conditional use permit. The zoning ordinance names who decides: the county commission, the city council, a planning commission, or a board of adjustment. The hearing is about that one project, and the decision must follow the standards already written in the ordinance.

  1. Speak, and put it in writing. Go to the hearing, give your name and address, and hand in a written copy of your comments. Ask that it be made part of the record.
  2. Tie your points to the ordinance. The deciding body must weigh the standards in the ordinance, the goals of the comprehensive plan, and the purpose of the zoning district. Comments that name a standard carry the most weight.
  3. Know the vote. A conditional use permit is approved by a majority of the members who are present and voting. In a county, a variance needs a two-thirds vote of the board of adjustment.
  4. The appeal clock is short. A person harmed by a decision of a county board of adjustment has 30 days after the decision is filed to ask the circuit court to review it. A permit decision is reviewed the same way, and the court gives weight to how the local board reads its own ordinance. City decisions follow a similar path. Talk to a lawyer early.

Local Leaders May Limit or Prohibit Data Centers

In 2026 the Legislature passed Senate Bill 135, the Data Center Bill of Rights for Citizens. It says the state may not take away or limit the power of a county, a city, or another local government to restrict, prohibit, or otherwise regulate data centers. Local leaders decide where data centers may go, how large they may be, and what they must do about noise, water, and cleanup.

What to ask for: clear written rules before a company applies. County zoning is optional in South Dakota, and a county with no zoning ordinance has few tools.

A Temporary Pause Is Allowed

A county or city that is studying the issue may adopt a temporary zoning ordinance, often called a moratorium. It must first hold a public hearing, with notice published at least 10 days ahead. The pause may last up to one year and may be renewed once, for no more than two years in all.

What this means for you: ask leaders to adopt rules before any company applies. If a project is already being discussed, ask for a temporary pause while the rules are written.

Sending a Decision to the Voters

Voters can refer a new ordinance, a zoning change, or a rezoning to a public vote. Voters can also propose an ordinance of their own. Only lawmaking decisions can be referred. A decision that simply carries out rules already on the books cannot.

5%of registered voters must sign
20days after the ordinance is published to turn in a referendum petition

A county petition goes to the county auditor. A city or town petition goes to the finance officer or clerk. Filing the petition puts the ordinance on hold until the vote. Twenty days is very little time: in January 2026 a Sioux Falls petition on a rezoning gathered 5,012 signatures when 6,704 were needed.

Getting Public Records

You can ask a county or city for drafts, letters and emails with a developer, and agreements. Start by asking the office that keeps the record. If any part of that request is turned down, send a written request to the public record officer.

10business days for the officer to answer a written request
90days to challenge a denial
1hour of staff time before a search fee may be charged

No answer within 10 business days counts as a denial. You may then go to circuit court or send a notice of review to the state Office of Hearing Examiners. Some business information that a company gives to the government may be withheld. The Letter Builder writes the request for you.
