STR guests must comply with Ontario Municipal Code Chapter 29 noise rules including 10 PM to 7 AM quiet hours. Operators are responsible for guest conduct and repeat noise violations can cost them the permit.
Short-term rental operators in Ontario are responsible for ensuring that their guests comply with the city noise ordinance in Ontario Municipal Code Chapter 29 (Sec. 5-29.07). The ordinance prohibits loud, excessive, impulsive, or intrusive noise that disturbs neighbors or offends a reasonable person, and applies nighttime quiet hours from 10 PM to 7 AM for residential areas. Amplified music, outdoor parties, and loud gatherings during quiet hours can trigger citations directed at the property owner or responsible party, not only the guests. STR listings must include written house rules specifying quiet hours, maximum occupancy, and a prohibition on outdoor amplified sound after 10 PM. Operators must post a 24-hour local contact name and phone number inside the unit and provide it to adjacent neighbors and the city. Multiple substantiated noise complaints within a 12-month window can lead to permit suspension or revocation. Ontario Police non-emergency (909) 986-6711 and Code Enforcement (909) 395-2025 respond to complaints.
