This process is similar to the one for an initiated ordinance, but with some important differences.
Charter amendments can be referred to a regular election or to a special election. For the purpose of a charter amendment only, "regular election" is narrowly defined as Denver's every-four-year municipal election.
Every other regularly-scheduled election is considered a "special election" in the case of a charter amendment. In addition, a special election with an approximate date chosen by the charter amendment petitioners can be designated.
Petitioners have a maximum of 90 days to gather signatures, but other time restrictions may reduce this window. The valid signature requirement is five percent of the total number of registered Denver voters if aiming for a regular election, or ten percent if a special election.
The exact number of signatures is determined on the date the petition materials are submitted. Currently, five percent of Denver's registered voters equals approximately 21,000 signatures, and ten percent is approximately 42,000 signatures. Note: The number of registered voters fluctuates. Contact the Elections Division to get the current number.
Petitioners are encouraged to gather an ample number of excess signatures to ensure at least the required number of signatures are confirmed valid.
