Weapons on School Grounds – California Penal Code 626.10 PC

California Penal Code § 626.10 PC strictly prohibits carrying, possessing, or bringing non-firearm dangerous weapons onto public or private educational property.

Designed to maintain safety across educational environments, this statute creates a broad restriction that applies to kindergarten through 12th grade (K-12) schools and public and private college and university campuses.

Unlike standard weapons laws that require brandishing or intent to use, simple physical possession of a restricted item on school property is sufficient to trigger criminal prosecution under PC 626.10.

Key Violations & Scope of the Law

Under PC 626.10, prosecutors can charge individuals carrying a wide variety of bladed, sharp, electrical, or projectile weapons. Common prohibited items include:

Bladed Weapons: Dirks, daggers, ice picks, straight razors, and any knife with a fixed or folding locking blade longer than 2.5 inches.
Electrical Stun Devices: Tasers and stun guns.
Projectile Devices: Any air pressure, CO2, or spring-action device that expels a metallic projectile (such as BB guns or pellet guns) and spot-marker paint guns.

Because PC 626.10 is classified as a wobbler offense, prosecutors have full discretion to file the charge as either a misdemeanor (up to 1 year in county jail) or a felony (up to 3 years in state prison) depending on the circumstances, the weapon involved, and the defendant's prior record.

Legal Definition Language

California Penal Code § 626.10(a)(1) PC states:

"Any person, except a duly appointed peace officer... who brings or possesses any dirk, dagger, ice pick, knife having a blade longer than 2 1/2 inches, folding knife with a blade that locks into place, razor with an unguarded blade, taser, or stun gun, any instrument that expels a metallic projectile such as a BB or a pellet, or any spot marker gun, upon the grounds of, or within, any public or private school providing instruction in kindergarten or any of grades 1 to 12, inclusive, is guilty of a public offense."

Effective Defense Strategies

An experienced California criminal defense attorney at the Esfandi Law Group can utilize multiple legal defenses to fight PC 626.10 charges:

Item Is Not a Statutorily Prohibited Weapon: The seized object does not meet the legal definition specified in the statute (e.g., the knife blade measures exactly 2.4 inches, or the knife lacks a locking mechanism).
Lack of Knowledge or Control: You were unaware the item was in your bag, vehicle, or possession, or you lacked control over a shared container.
Statutory Exemption or Authorized Purpose: You fall under a protected class (e.g., active peace officer or military on official duty), or had explicit written authorization from a school official for educational or job-related purposes (e.g., culinary tools or maintenance equipment).
Unconstitutional Search and Seizure (Fourth Amendment Violation): Law enforcement searched your person or property without reasonable suspicion, probable cause, or a valid warrant. Evidence obtained illegally can be suppressed via a Motion to Suppress under PC 1538.5.
