2026 London ARU Parking & Driveway By-laws

London's current ARU direction is helpful for homeowners with tight lots: no additional parking is required for an ARU. That does not mean every driveway change is allowed, so parking should be reviewed as part of the site plan rather than treated as a separate afterthought.

Decision guide

Check the property before you spend on plans

Use the lot, loan, rent-cap, and servicing screens to decide whether the next step should be design work, a builder conversation, or more research.

  • Check the address
  • Review the loan rules
  • Confirm the rent math
  • Budget the hidden costs

No Extra Parking Required

Under London's current ARU framework, an additional parking space is not required just because an ARU is added. This can make smaller lots, mature neighbourhoods, and campus-area properties more realistic because the project does not need to sacrifice green space for a new stall. For rental-heavy areas, pair this with the student-rental ARU guide.

No extra parking required does not mean no site-plan review. Existing driveway and access conditions still matter.

Driveway Restrictions

London also restricts adding a new driveway simply to serve the ARU. That policy direction protects streetscape, walkability, drainage, and green space. Before widening pavement or planning a new curb cut, confirm whether the existing driveway arrangement can remain as-is and whether the site plan still satisfies zoning and access requirements.

  • Do not assume a second driveway is available for a backyard suite.
  • Keep driveway changes out of the budget until the site plan is checked.
  • Consider tenant access, snow storage, waste storage, and emergency access together.

FAQ

Common questions, answered plainly

Does London require an extra parking space for an ARU?

Current London ARU rules do not require an additional parking space solely because an ARU is added.

Can I add a new driveway for my ARU tenant?

Do not assume so. London restricts adding a new driveway to serve an ARU, so driveway changes should be reviewed before they are included in a plan.
