How Many Signatures Do You Need to Run for Office in Illinois?

It depends on the office. In Illinois, a precinct committeeperson needs at least 10 signatures, a school board or community college candidate needs 50 or 10% (whichever is less), a Chicago alderperson needs at least 473, and Chicago's mayor, clerk and treasurer need at least 12,500. Many municipal offices use a percentage instead: 0.5% of the party's primary voters for party candidates, 1% of the last village president vote for nonpartisan village candidates, and 5% to 8% for nonpartisan city candidates and independents.

Whatever your number is, treat it as a floor, not a target. Objections can strike signatures after you file, so collect a margin above the minimum and confirm your exact requirement with your election authority before you start. The table below lists each office with its statute, and the rest of this post covers how to turn that number into a plan you can walk.

Signature requirements by office

These figures come from the Illinois State Board of Elections 2027 Candidate's Guide. For the full picture of petition season, including the paper rules and the objection process, see our guide to Illinois nominating petitions.

Party committeepersons

Committeeperson petitions follow 10 ILCS 5/7-10(i):

• Precinct committeeperson (outside Cook County): at least 10 signatures of the party's primary electors in the precinct.
• Ward committeeperson (Chicago): 10% to 16% of the party's primary electors in the ward.
• Township committeeperson (suburban Cook County): 5% to 8% of the party's primary electors in the township.

For ward and township committeepersons, the maximum is the higher percentage or 50 above the minimum, whichever is greater. Committeepersons are elected at the general primary, not at the 2027 consolidated elections, so these petitions are on a different calendar from the offices above.

Getting your exact number

Percentages only become numbers once someone applies them to the right base, such as the count of a party's primary voters in your municipality at the last regular election. Your county clerk or board of election commissioners can give you that figure and the resulting minimum. Ask for it in writing if you can, and ask whether your office has a maximum as well.

Why the minimum is not the goal

A petition that meets the minimum on filing day can fall below it a few weeks later. After filing, there is a window for objections (through November 2, 2026 on the February track and December 1 or 2, 2026 on the April track), and signatures found invalid are struck. The usual reasons are ones you can see coming:

• Signers outside the district. A friendly neighbor one block past the boundary does not count.
• Duplicates. The same person signing twice, perhaps once for you and once for a volunteer, counts once.
• Signers who are not eligible for that petition, such as a voter who is not one of the party's primary electors on a party petition.

As common practice, many campaigns aim for 1.5 to 2 times the minimum. That is not a legal rule, and offices with a range (such as 5% to 8%) also have a ceiling to stay under. We go into how to size the cushion in how many signatures to collect above the minimum.

Turning your number into doors

Collecting door to door takes planning, but every signature comes from a household you already know is in your district, and every visit is a conversation with a voter. Here is how to plan it.

Start with your target, then your rates

Your target is your minimum plus your margin. To turn it into doors, you need two rates from your own district: the share of doors where someone answers, and the share of those people who sign. You will not know them until you have walked a few evenings, so start with an estimate and replace it with real numbers quickly.

As an illustration only, suppose you need 50 signatures and aim for 100. If, in your first sessions, someone answers at about one door in three and about half of them sign, each signature takes about six doors. That points to roughly 600 doors. If a circulator covers 25 doors an hour, that is 24 circulator hours, or a few weekends for a small team. Your numbers will differ; the method is what carries over.

Work from a household list

Ask your county party or your election authority for a list of households in your district, and confirm the boundary before you cut turf. Divide the list into turfs that one person can finish in a session, assign each to a circulator, and send circulators back to the doors where no one was home before opening new turf.

Track every door

The doors where nobody answered are where most of your extra signatures come from. A record of which doors were visited, what happened, and which ones need a second try keeps a team from walking the same street twice while another street goes untouched.

This is where Beacon helps. Beacon puts your walk list on a map, routes circulators door to door, and records the result at each door: contacted, not home, come back later and more. You can add a survey question such as "signed: yes/no" to see progress by turf. The paper sheet remains the legal record of every signature; Beacon keeps track of the doors.

The paper rules

Illinois candidate petitions are signed in ink on the official form, and each sheet carries a notarized circulator statement from the person who collected the signatures on it. There is no electronic signature option for these petitions. A few habits help:

• Use only the official form for your office, and give each circulator their own sheets.
• Check sheets as they come in, while it is still easy to go back to a door.
• Plan notary time into your schedule so finished sheets do not sit waiting.

The 2027 filing windows

The 2027 consolidated elections run on two tracks, and filing periods moved about three weeks earlier this cycle (P.A. 103-0586 and 103-0600).

Confirm your track with your village or county clerk, especially if you are running for a nonpartisan village office.

Frequently asked questions

How many signatures do I need to run for school board in Illinois?

50 signatures or 10%, whichever is less (105 ILCS 5/9-10). School board races are on the April 6, 2027 track, with filing November 16 to 23, 2026. Confirm the exact figure for your district with your election authority.

How many signatures does a Chicago alderperson need?

At least 473 per ward (65 ILCS 20/21-28). Chicago offices are on the February 23, 2027 track and file October 19 to 26, 2026.

Can petition signatures be collected electronically in Illinois?

No. Candidate and committeeperson petitions are signed in ink on the official form, with a notarized circulator statement on each sheet.

Do I really need more than the minimum?

Yes. Objections can strike invalid signatures after you file. Many campaigns aim for 1.5 to 2 times the minimum as common practice, staying under any maximum their office has.

Plan your petition walk

Knowing your number is the first step; reaching it with room to spare is the work. Beacon gives your circulators a map, an efficient route and a clear record of every door, with unlimited canvassers on every plan. Start a 14-day Beacon trial and have your first turf ready for this weekend.
