Thornton Graffiti Removal Program 

Property owners are eligible to take advantage of the City of Thornton's free graffiti removal program. *If you see someone tagging graffiti call Thornton Police at 9-1-1.

The City Code allows the city to remove graffiti from specific property with the written permission of the property owner.  The city will remove graffiti on buildings, houses, fences, walls, and signs that are accessible by the city's equipment.  The graffiti removal program operates Monday-Friday 8 a.m. to 5 p.m.

Authorization Waivers

To participate in the city's Graffiti Removal program, the property owner must complete and sign the waiver and consent form, which can be found under Graffiti Removal links on this page.  This waiver allows a city staff or its contractor to step onto the property to remove the graffiti.

The property owner must sign a waiver that gives the City consent to step onto the property to remove the graffiti. This waiver will authorize one-time or ongoing removal. If the waiver is not signed, the property owner will be responsible to remove the graffiti within 10 days.
