Frequently Asked Questions

What are the Town of Aurora parking requirements for a second unit?

Under the Town of Aurora zoning bylaws, a residential property containing a second dwelling unit must provide a minimum of 1 dedicated, off-street parking space designated specifically for the secondary unit tenant. This space must be provided in addition to the parking required for the principal residence and must not conflict with municipal front-yard soft landscaping requirements.

What headroom metrics apply to a legal basement ceiling in Aurora?

To secure municipal registration from the Town of Aurora, the lower-level suite requires an absolute finished vertical clearance of 1.95 meters (6 feet, 5 inches) in all living areas, kitchens, and bedrooms. The code allows a minor concession for mechanical components: localized bulkheads sheltering heating ducts or plumbing drains can drop to a minimum of 1.85 meters (6 feet, 1 inch). Any space falling below these continuous thresholds requires structural excavation and floor lowering to achieve legal compliance.

Is an independent electrical inspection required in Aurora?

Yes. Before the Town of Aurora will issue a final occupancy permit or add the secondary suite to the municipal registry, a separate inspection by the Electrical Safety Authority (ESA) must be completed. This ensures that all new wiring, circuits, and the dedicated sub-panel meet the strict requirements of the Ontario Electrical Safety Code.
