When an enforcement officer believes that a person has committed a penal violation of this code or a supplementary ordinance, but further believes that the person was honestly unaware of the violation, or will voluntarily cease the offending act or remedy the offending condition without the need to impose penalties or take any other formal action for enforcement, the enforcement officer may issue and serve to the person a warning citation. A warning citation does not require the person to pay a fine, make a security deposit, sign a notice to appear or take any other action except to cease the act or correct the condition. A warning citation will not be filed with the court of jurisdiction and does not create a presumption of guilt for purposes of § 33.31. However, when the provision to which the warning pertains expressly provides that a violator be given a "grace period" of a specified time to correct a condition or desist from an act of violation before being subject to penalties or other action, the date of the warning citation shall be considered as the beginning of the grace period. The same form of citation as would otherwise be used may be used for a warning citation, but all copies thereof must be clearly marked, "Warning Only."
