Bylaws related to residential car washing

Can I wash my car on the street?

Under theDrainage Bylaw 37M2005, you may use only water to clean your car. If you are washing your car on the street, you must not use any kind of soap or any product other than water, and your car must not be overly dirty.

Since the Drainage Bylaw states that only water may enter the storm sewers, we strongly suggest using a carwash to wash vehicles.

What is the fine for washing my car with soap on the street?

The specified fine for violating this section of the bylaw is $500 for a first offence.

Can I use biodegradable soap to wash my car on the street?

No. All soaps and detergents are prohibited substances under the Drainage Bylaw. Only plain water can be used to wash vehicles.
