The City Clerk will review the proposed petition form for conformance to the established standards listed below.

Petitions must be printed or typed on single sheets of white paper of good quality and each sheet of petition paper having a space thereon for signatures must contain the text of the petition and the following warning language: (RCW 35.21.005; SMC 2.08.040)


Every person who signs this petition with any other than his or her true name, or who knowingly signs more than one of these petitions, or signs a petition seeking an election when he or she is not a legal voter, or signs a petition when he or she is otherwise not qualified to sign, or who makes herein any false statement, shall be guilty of a misdemeanor.

In addition, it is unlawful for any person:

  • 1. To sign or decline to sign any petition for a City initiative, referendum, or Charter amendment, in exchange for any consideration or gratuity or promise thereof; or
  • 2. To give or offer any consideration or gratuity to anyone to induce him or her to sign or not to sign a petition for a City initiative, referendum, or Charter amendment; or
  • 3. To interfere with or attempt to interfere with the right of any voter to sign or not to sign a petition for a City initiative, referendum, or Charter amendment by threat, intimidation or any other corrupt means or practice; or
  • 4. To sign any City of Seattle initiative, referendum, or Charter amendment knowing that he or she is not a registered voter of The City of Seattle.
Any violation of paragraphs 1, 2, 3, or 4 shall be punishable by a fine of not more than $500 or by imprisonment for a period not to exceed six months, or by both such fine and imprisonment. (Seattle Ordinance 94289, SMC 2.08.040, RCW 35.21.005)."


"To the City Council of The City of Seattle:

We, the undersigned registered voters of The City of Seattle, State of Washington, propose and ask for the amendment to the City of Seattle Charter known as Charter Amendment Measure No. . . . . . . entitled:

(here set forth the established ballot title of the measure),

a full, true and correct copy of which is included herein, and we petition the Council to present said proposed Charter Amendment to the qualified electors of The City of Seattle for approval or rejection at the next general municipal election occurring in accordance with Article XX, Section 2 of the City Charter; and each of us for himself or herself says: I have personally signed this petition; I am a registered voter of The City of Seattle, State of Washington, and my residence address is correctly stated."

The City Clerk will review for the following:

  • Does the petition contain the name, address and phone number (optional) of petitioner or contact person? (SMC 2.08.010)
  • Is the petition typewritten and in a readable font? (SMC 2.08.010)
  • Is the petition printed on single sheets of paper of good writing quality? (SMC 2.08.030)
  • Are the petition pages at least 8 ½" wide and 11" long, and not larger than 11" wide and 17" long? (SMC 2.08.030)
  • Is there a top margin of at least 1"? (SMC 2.08.030)
  • Are the signature lines numbered and are there not more than 20 signatures per page? (SMC 2.08.030)
Approval of Petition Form and Text The City Clerk will notify the petition coordinator of the completed review of the proposed charter amendment petition within five business days after the date filed with the City Clerk (SMC 2.08.010.B). The City Clerk will let the petition coordinator know if the form of the petition was approved or rejected both in a letter and a phone call.

If approved, the City Clerk will also:

  • Provide the ballot title to the petition coordinator (SMC 2.08.010.B, SMC 2.08.020).
  • Provide a copy of the petition form to the Executive Director of the Ethics and Elections Commission (SMC 2.08.010.B).
If the petition coordinator requests a change to the original document filed, the change will be considered a new filing. (File the document with changes according to Step 2.)
Step 4: Preparation of Ballot Title      top of page
The City Attorney must prepare the ballot title within five business days after receipt of the approved petition from the City Clerk (SMC 2.08.020; RCW 29A.36.071).

The ballot title must conform to the requirements of RCW 29A.36.071 and RCW 29A.72.050.

After preparation of the ballot title, the City Attorney must transmit it to the City Clerk, who must then file it with the King County Director of Records and Elections (SMC 2.08.020).

After a ballot title prepared by the City Attorney's Office has been filed with King County Elections, any person dissatisfied with the ballot title has ten days, not including Saturdays, Sundays, and legal holidays, to appeal the King County Superior Court. The decision of the superior court is final, and the ballot title or statement certified by the court will be the established ballot title (RCW 29A.36.090).
Step 5: Procuring Signatures      top of page
Paid signature gatherers collecting petition signatures for Seattle ballot measures must visibly display a statement showing they are a "paid signature gatherer" to each person from whom they receive a signature. This may be fulfilled by posting a legible and conspicuous sign, or placard, or wearing a badge stating "Paid Signature Gatherer" (SMC 2.04.606).

Fifteen percent (15%) of the total votes cast for mayor at the last Mayoral election is the number of registered voter signatures needed to validate the initiative (Seattle City Charter Art. XX, Section 2).

Example: 2021 Mayoral race - 265,203 votes cast, so until the next Mayoral election, 39,780 valid signatures of registered Seattle voters will be required to qualify a charter amendment.

Each signature must be executed in ink or indelible pencil and must be followed by the printed name and address of the signer and the date of signing (RCW 35.21.005(2)). (If additional information is requested on the petition, it must be noted as "optional.")

Signatures must be gathered within the 6 month period prior to submitting the signatures to the City Clerk (RCW 35.21.005(8)).

If a person signs a petition more than once, all but the first valid signature must be rejected. (RCW 35.21.005(7); Filo Foods LLC v. City of SeaTac, 179 Wn.App. 401, 319 P.3d 817 (2014)).
Step 6: Signature Submittal      top of page
When the required number of signatures are collected, the petition coordinator must file the signed petitions with the Office of the City Clerk.

Contact with the City Clerk is recommended in advance in order to schedule an appointment for the submission of the petitions.

At the time the petitions are filed, an estimate of the number of signatures and number of petition pages will be requested.

The pages should be numbered in sequence, beginning with 1 or 001, etc., in the upper right corner of each sheet.

The City Clerk will transmit the petitions to King County Records and Elections Division within three business days after they have been filed (RCW 35.21.005(4)).

Upon receipt of the petitions, King County Records and Elections Division will verify the validity of the signatures to determine sufficiency or insufficiency. (Refer to Step 4 regarding the percentage formula used to determine the number of valid signatures required.)

Terminal Date - Additional signatures

The date on which King County Records and Elections begins its determination will be set as the "terminal date." Additional pages of one or more signatures may be added to the petition by filing the same with the City Clerk before the terminal date (RCW 35.21.005(4)).

Terminal Date - Withdrawing signatures

Any signer of a filed petition may withdraw his or her signature by a written request for withdrawal filed with the City Clerk before the terminal date. Such written request must sufficiently describe the petition so as to make identification of the person and the petition certain. The name of any person seeking to withdraw shall be signed exactly the same as contained on the petition (RCW 35.21.005(4)).

King County Records and Elections is required to make such a determination with "reasonable promptness" (RCW 35.21.005(4)).

All signatures followed by a date of signing which is more than six months prior to the date of filing of the petition with the City Clerk shall be stricken (RCW 35.21.005(8)).

Step 7: Council Action Placing Measure on the Ballot      top of page
If a sufficient number of valid signatures have been verified, the Council will pass a bill or adopt a resolution authorizing King County Elections to place the charter amendment on the ballot for a forthcoming general municipal election occurring at least sixty days after the filing of the petition (Seattle City Charter Art. XX, Section 2).

General municipal elections are held throughout the state of Washington on the first Tuesday following the first Monday in November in the odd-numbered years. (RCW 29A.04.330(1)).

The resolution must be presented to the county auditor no later than the day of the primary in an odd-numbered year which is held on the first Tuesday of August (RCW 29A.04.330(1); RCW 29A.04.330(2)(d); RCW 29A.04.330(3); RCW 29A.04.311).
Step 8: Election Results      top of page
Following the election, written notice will be sent to the City Clerk from King County certifying the results of the vote count.

If the charter amendment was passed by a majority of the voters, it becomes part of the Charter upon proclamation of the Mayor (within five days after certification of the election). Notice will be published in the City's official newspaper, the Daily Journal of Commerce) (Seattle City Charter Art. XX, Section 2).
