How do I widen my driveway?
Submit an encroachment permit application to Ontario Public Works and a zoning clearance from Planning.
Rialto FAQ
Can I park my car on the lawn in front of my Rialto house?
No. Rialto Title 18 zoning standards require residential vehicles to be parked on a paved, all-weather surface. Front-lawn or unpaved-yard parking is a Code Compliance violation.
