MONROVIA, Los Angeles County — October 25, 2026. Monrovia’s official city calendar lists an upcoming Halloween Spooktacular & Trick-or-Treat Bash on Saturday, October 31, beginning at 3 p.m. The same municipal calendar shows a Historic Preservation Commission meeting Wednesday, October 28, at 7:30 p.m. These are separate events, and residents should consult their individual notices for current venues and participation details.

Halloween Spooktacular: October 31

The city’s October 2026 calendar identifies the event and starting time. The calendar overview does not establish all activities, whether costumes are required, whether any activity is age-restricted, or the exact end time. Parents should follow the organizer’s details for parking, accessibility, treats and any sign-up requirements. Previous October events, including the October 10 Old Town Fall Festival, have already taken place and should not be confused with the Halloween celebration.

Historic Preservation Commission: October 28

The city’s schedule lists the commission for 7:30 p.m. Wednesday, October 28. People interested in local architecture, historic properties and preservation applications should obtain the actual meeting agenda to confirm which sites, reports or proposed actions will be considered. An upcoming commission date is not proof that an application has been approved.

How to find city records

Monrovia also maintains a public OnBase document portal offering Council agenda reports, board and commission materials, building-permit records and document searches. The city advises that some browser pop-up settings may interfere with the records portal. Residents who cannot access a document should contact the appropriate city department rather than assuming records are unavailable.
