What are the parking requirements to register an ADU?
Residences with ADUs are required to have a minimum of three exterior parking spaces (not including the garage).
How do I obtain additional parking spaces?
You may contact the Town's Planning department at 905-953-5300 ext. 2450 or email@example.com.
How many bags of garbage can I put out and how does the garbage collector know that I'm a registered unit?
When there are two units within one residence, the number of garbage bags allowed for each residence with a registered ADU doubles. Example: Three bags are allowed for the upper unit and three bags are allowed for the lower unit, for a total of six bags.
The collector will know that your residence is a registered unit by the "N" plate. The "N" plate must be affixed to the front of the house and visible from the road.
I'm moving out and have additional garbage bags. How do I ensure my excess garbage is picked up?
Excess garbage will be picked up provided it has garbage tags. Garbage tags can be purchased at Municipal Offices, Magna Centre, Ray Twinney Recreation Complex and the Newmarket Operations Centre.
Who should I contact if I have an issue with my landlord or other issues in my residence?
If you have a concern or issue with your landlord, contact the Landlord Tenant Board or call 1-888-332-3234.
