Driveway Widening

From time to time people may want to widen their residential driveway to accommodate more parking, or to facilitate maneuverability.  It is important to remember that all private driveways are the responsibility for the homeowner to properly maintain.

'Driveway', as per the City of London Zoning By-law, "means a vehicle access provided between a street or lane and a parking area or a loading space, or between two parking areas, but does not include a parking aisle."  An 'access driveway' "means the area between the travelled portion of a road and a parking area used by motor vehicles for access to and from the parking area." 

Making a Decision:

You will be responsible to ensure that no other utilities or municipal functions are impacted by the widening of your driveway. Confirm that none of these "obstacles" are in proximity to your project, as it is very costly to have any of these items (re)moved:

- Trees, bus shelters, street signs;

- Hydro poles, telephone poles, cable or phone boxes, or other utilities;

- Storm drains, fire hydrants, mailboxes, or other municipal infrastructure.

Where you are uncertain about underground utilities, you should call Ontario One Call (ON1Call)

Maximum Driveway Width(s):

The maximum width of any residential driveway in the City of London is 50% of the lot frontage, to a maximum of 8.0m (26.3 feet), whichever is less. The driveway width shall be measured parallel to the street at the street line. No lot shall have more than two driveways for the first 30.0 metres. (98.7 feet) of street line. The minimum driveway width is 2.7m (8.8 feet).


Lot Frontage Maximum Width Permitted
Sample Driveway Widths
6.0m (approx. 20 feet) 3.0m (approx. 10 feet)
8.0m (approx. 26 feet) 4.0m (approx. 13 feet)
12.0m (approx. 40 feet) 6.0m (approx. 20 feet)
16.0m (approx. 52 feet) 8.0m (approx. 26 feet)
Greater than 16.0m 8.0m (approx. 26 feet)



Note: For lots with a curved frontage, please contact zoning (see Zoning in Contact Us) for assistance in calculating frontage and maximum driveway width.

Application for Driveway Widening and Curb Cutting:

After you've planned your project, you can apply for a permit by printing and submitting this form.  The application will be circulated to various departments for review and approval.  The completed form can be emailed to or dropped off on the 7th floor of City Hall.

Once approved, you will need to contact a contractor to do the actual work for you, as has been approved through the application.  The contractor will inform you as to how much your curb cut will cost.  You can get multiple quotes if you wish, based on the approved permit.

Note: Where mistakes are made, or work undertaken without a permit, you will be held responsible for the cost of replacing the infrastructure, grass, curbs, etc. If you have any questions about any steps in the process, please contact Development and Compliance Services at the number to the right.


Frequently Asked Questions

  • Can I park in my front yard?

    No; The City of London prohibits parking in your front yard.  The existing (and widened) driveway must lead to a garage, or to a legal parking spot at the side/rear of your home.  However, driveways and/or walkways connected to and parallel to a driveway may project up to a maximum of 2.0 metres (6 feet) into the front yard of a single detached, semi-detached, duplex or converted two unit dwelling. That part of the required front yard not used for a driveway or walkway shall be used exclusively for landscaped open space.

  • Where can I park?

    Parking for residential purposes is permitted in the interior side yard and rear yard, provided that no part of any parking area is located closer than 1.0 metres (3.3 feet) to any required road allowance and provided that no part of any rear yard parking area is located closer than 3.0 metres (9.8 feet) from the rear lot line and 3.0 metres (9.8 feet) from any one side lot line in the rear yard. See Section 4.19[4] of the Zoning by-law for more details.  Always contact the zoning department @519-930-3510 should you have any questions about where you are permitted to park.

  • What are the dimensions of a parking space?

    "A parking space shall have minimum dimensions of 2.7 metres by 5.5 metres".  Notwithstanding, in order to create a legal parking space, you therefore would require a 6.5 driveway to accommodate the 5.5.m length, and the 1.0m setback to any required road allowance.

  • Do I need a permit to widen my driveway?

    There are a number of technical details which must be addressed before you can apply for the permit to cut the curb, which in turn allows you to widen your driveway.  After reading the page above, should you still have questions, please contact Customer Relations and Compliance (Janice Smith) and speak to her about widening your driveway.

  • Can I have more than one driveway?

    Yes, but "where more than one driveway leading to a parking area/private garage for a single detached, semi-detached, duplex, or converted two-unit
    dwelling is provided, the combined total of all driveways shall not exceed the provision of 4.19 6) (h) (I). of the Z.-1 Zoning By-law.  That provision sets out the maximum driveway widths.  You may not have more than two driveways in the first 30m (98 feet) of street line.  Please note: you are not permitted to drive across your lawn to access your driveway or to park.  Driveways must lead to legal parking areas.

  • Can my driveway go right up to my property line?

    Technically speaking, yes, your driveway may be right up to the property line, so long as it does not exceed the maximum width permitted for your property.  Notwithstanding, you cannot direct water off of your driveway onto your neighbours property.  Make sure you grade your driveway so as to direct water away from nieghbouring properties.
