How Many Signatures Do You Need to Run for Office in Iowa?
It depends on the office and, for city offices, on how your city nominates its candidates. In a city with primary or runoff provisions, a city candidate needs signatures equal to at least 2 percent of the people who voted for that office at the last regular city election, and never fewer than 10. In a city that uses chapter 45 nominations, the number is set by population: 75, 50, 25 or 10. A school board candidate needs the greater of 10 signatures or 1 percent of the registered voters in the district, but never more than 50. A community college board candidate needs 50 signatures from the director district.
The Iowa Code sections that set these numbers state a minimum only, so your goal is a number comfortably above it. Confirm your exact number with your county auditor before you start, because it depends on figures only the auditor can give you, such as last election's vote. For the rest of petition season, including the filing windows, the paper rules and objections, see our guide to Iowa nomination petitions.
Signature requirements by office
| Office | Minimum signatures | Iowa Code |
|---|---|---|
| City office, in a city with primary or runoff provisions | 2 percent of the people who voted for that office at the last regular city election, and at least 10 | 376.4 |
| City office, chapter 45 city of 25,000 or more people | 75 | 45.1 |
| City office, chapter 45 city of 7,500 to 24,999 | 50 | 45.1 |
| City office, chapter 45 city of 2,500 to 7,499 | 25 | 45.1 |
| City office, chapter 45 city under 2,500 | 10 | 45.1 |
| School board director | The greater of 10 or 1 percent of registered voters, no more than 50 required | 277.4 |
| Community college board director | 50 eligible electors of the director district | 260C.15 |
Population for chapter 45 cities is based on the most recent federal census (45.1). Section 45.1 also sets a separate number for certain special charter cities, so if your city has a special charter, ask your county auditor which number applies.
City offices: first learn your city's nomination method
Every Iowa city uses one of three nomination methods, and the method decides which row of the table applies (376.6):
- Primary provisions. The default under state law. A primary is held on Tuesday, October 5, 2027, only for an office where more than twice as many candidates file as there are seats. The 2 percent rule applies.
- Runoff provisions. The city chose, by ordinance, a runoff after the election instead of a primary. The 2 percent rule applies.
- Chapter 45 nominations. The city chose, by ordinance, nominations under chapter 45, with no primary or runoff. The population numbers apply.
Each city clerk certifies the city's method to the county auditor by Wednesday, August 4, 2027 (based on state law). Ask your city clerk or county auditor long before then, because the method also sets your filing window.
How the 2 percent rule works
The number is based on how many people voted for the same office at the last regular city election, not on the number of registered voters (376.4). As an illustration only: if 1,500 people voted for a council seat at the last regular city election, 2 percent is 30, so you need at least 30 valid signatures. If 2 percent comes to fewer than 10, you still need 10.
Ask your county auditor for the right vote figure for your office, in writing if you can, especially for a ward seat or an at-large race with several seats.
Ward seats and at-large seats
Where a council seat is voted on only by the residents of a ward, every signer must live in that ward when they sign (376.4). Where council members must live in a ward but are elected by the whole city, the Secretary of State's guide says signers may live anywhere in the city. For mayor and other citywide offices, any eligible elector of the city may sign.
School boards: 10 to 50 signatures
The rule in Iowa Code 277.4 is the greater of 10 eligible electors or 1 percent of the registered voters, with no more than 50 required. In practice:
| Registered voters in the district or director district | Minimum signatures |
|---|---|
| Up to 1,000 | 10 |
| 1,000 to 5,000 | 1 percent (10 to 50) |
| More than 5,000 | 50 |
As an illustration only, a school district with 3,000 registered voters needs 30 signatures.
Which voters you count depends on how the seat is elected. For an at-large seat, or a director district seat elected by the whole school district, the count uses the whole district's registered voters, and signers may live anywhere in the district. For a seat that only a director district's voters elect, the count uses that director district's registered voters, and every signer must live in the director district (277.4). The Secretary of State's 2023 guide based the count on registered voters as of May 1 of the election year, so ask your county auditor which figure applies in 2027.
Community college boards: 50 from the director district
A community college board candidate needs a petition signed by at least 50 eligible electors of the director district (260C.15). The number does not change with the size of the district. Each signer also writes the school district they live in, and the Secretary of State's guide says lines without it cannot be counted.
Whose signatures count
A signature counts only if the signer could legally sign your petition:
- An eligible elector of the area. That is a person who meets every requirement to register to vote, according to the Secretary of State's guides. The signer must still be an eligible elector of the area when you file.
- A complete line. The line needs the signer's signature (the state guides say it may be printed), a residential address with house number, street and city, and the date of signing. A line with only a post office box, a partial address, or an address plainly outside the ward or district is not counted (45.5).
- Nothing crossed out. A line with required information crossed out or redacted when filed is not counted (45.5).
- On a complete page. Signatures count only on pages whose candidate header is filled in at the top, including the ward or director district number when the seat has one (45.5).
A person may sign petitions for more than one candidate for the same office without invalidating the signature (376.4, 277.4, 260C.15), and you may sign your own petition if you are an eligible elector there. Our post on filling out and circulating an Iowa nomination petition covers each line of the form.
Choosing a target above the minimum
The Secretary of State's filing checklist says to file more than the required number of signatures, because signatures can be challenged. How far above the minimum to aim depends on your risk: a first-time candidate collecting with new volunteers has more reason to aim high than one who gathered every line in person.
As an example only, a school board candidate whose minimum is 25 might aim for 40. That leaves room for a number of struck lines. Before filing, you may draw a line through any signature you do not want counted, according to the state guides. Our general guide on how many signatures to collect above the minimum explains how to weigh the risk; it uses Illinois examples, so apply only its reasoning, not its numbers.
Turning your target into doors
To turn a signature target into doors, you need two rates from your own ward or district: the share of doors where someone answers, and the share of those people who sign.
As an illustration only, suppose your target is 40. If someone answers at about one door in three, and about half of them sign, each signature takes about six doors, or roughly 240 doors in all. At 25 doors an hour, that is about 10 hours of door knocking. Your rates will differ, so measure them over your first few sessions and adjust.
Second visits to doors where nobody answered can supply extra signatures, so keep a clear record of which doors were visited. Beacon is built for this part of the job. Draw each volunteer's turf on the map inside your ward or district, and assign it. Add your contacts, and each downloaded walk list puts its stops in walking order by distance. Beacon routes circulators door to door and records which doors were visited and the result: contacted, not home, come back later and the other door codes. Circulators can note "signed" or "not signed" in each door result's Notes field. The signed paper stays the legal record of every signature, and Beacon keeps the record of the doors, with unlimited canvassers on every plan.

Frequently asked questions
How many signatures do I need to run for city council in Iowa?
In a city with primary or runoff provisions, at least 2 percent of the people who voted for that seat at the last regular city election, and never fewer than 10. In a chapter 45 city, 75, 50, 25 or 10, depending on population. For a ward seat elected only by the ward, every signer must live in the ward.
Do petition signers have to be registered voters?
They must be eligible electors of the area, and the Secretary of State's guides define an eligible elector as someone who meets every requirement to register to vote, whether or not they are registered. Each signer must still qualify when you file.
Reach your number with room to spare
Knowing your number is the first step. Much of the work goes into reaching it with complete lines from addresses inside your ward or district. Beacon gives your volunteers turf on a map, a walk list in walking order by distance and a record of every door, with unlimited canvassers on every plan. Start a 14-day Beacon trial and have your first turf ready for your first weekend of collecting.
