Verify what is permitted
Driveway and curb rules vary by municipality and property. Width, landscaped area and changes to street access may be regulated, so the specific address and current municipal information should be checked before construction is scheduled. A neighbour’s layout is not proof of approval.
Examine the existing edge
An extension joins concrete of a different age. If the original edge has settled or the driveway is already deteriorating, the new strip may create a clean line beside a surface likely to need replacement. Colour and weathering will also differ.
Keep drainage working
Widening replaces permeable or landscaped area with hard surface and changes where rain lands. The extension should not create a channel toward the garage, house or neighbouring property.
