Frequently Asked Questions

How do private septic capacities restrict legal basements in rural King?

For properties in King Township operating on private wells and septic systems, a licensed engineer must verify that the existing tank and leaching bed possess the design capacity to handle the increased daily sewage load from added basement plumbing fixtures before any building permits are granted.

What are King Township's zoning rules regarding secondary suites?

King Township permits secondary dwelling units within single-detached dwellings, provided the property complies with minimum lot sizes, unencumbered parking allocations, and specific setbacks. The unit must also respect regulations enforced by local conservation authorities where applicable.

What fire containment standards are required for a legal basement in King?

To comply with the Ontario Building Code, a minimum 30-minute to 45-minute fire-resistance rating must separate the units. This requires mounting continuous Type X fire-rated drywall over resilient channels on the ceiling cavity, packing all floor joist spaces with dense mineral wool insulation, and installing hardwired, interconnected smoke alarms.
