Weed & Refuse Abatement

What is the Weed & Refuse Abatement Program?

The purpose of this program is to prevent fire hazards posed by overgrown weeds and the accumulation of combustible materials, as well as enhance the appearance of the City. 

City staff will inspect vacant lots within Ontario twice a year during Spring and Fall. Additional inspections may occur due to weather. Staff will ensure that minimum fire safety standards are adhered to (see standards below). 

The Ontario Municipal Code property maintenance section requires all properties in the City to be maintained free of debris, with trees trimmed and dilapidated fences removed or repaired. If a vacant lot is not in compliance at the time of initial inspection, the property owner will be issued a Notice of Violation along with the corresponding fee. If after a second inspection the vacant lot is still not in compliance, a civil penalty, re-inspection fee, and a Notice of Intent to Abate will also be issued. Staff will then direct a City contractor to abate all weeds, rubbish, and/or refuse on the vacant lot. 

All costs associated with abatement of weeds and refuse will be assessed to the property owner. Failure to pay fines, penalties and abatement costs will result in a special assessment being placed on the property tax bill.
