Trespassing Enforcement Program

In an effort to empower property owners, their authorized representatives, and those in lawful possession, this Trespassing Enforcement Program has been designed to provide a valuable tool. This program aims to facilitate effective property management, ultimately contributing to a safer environment through enhanced enforcement measures.


This program is to give the owner, owner’s agent, or person in lawful possession a tool which will allow them to better manage their property; therefore creating a safer environment through enforcement.

The owner, owner’s agent, or person in lawful possession completes the Trespass Enforcement Form below.
If property meets the criteria, “NO TRESPASSING” signs will be posted by the responsible party as outlined on the instructions for posting section. After the signs are posted, a Rialto Police Officer will inspect the property to determine whether the posted signs are acceptable. After the authorization is complete, enforcement begins. A copy of all documentation should be kept for personal records.

Documentation for this program will be kept and monitored by the Rialto Police Department.

Questions? Email us:

Enforcement will be effective for one year (365 days), unless indicated otherwise. It is the responsibility of the owner, owner’s agent, or person in lawful possession to submit a written request to renew or cancel the enforcement program.
