Frequently Asked Questions

What are Clarington's zoning rules regarding secondary suites?

The Municipality of Clarington permits secondary dwelling units within single-detached, semi-detached, and townhouses, provided the property complies with lot coverage, specific setbacks, and dedicated parking allocations verified during the initial zoning review.

How is emergency exit compliance handled in Clarington basement suites?

If the suite lacks a direct grade-level walkout door, we excavate and install a code-compliant egress window system. The window must provide an unobstructed opening of at least 0.35 square meters with a minimum dimension of 380 mm, accompanied by a structural window well that allows clear movement to the outside.

Can a Clarington legal basement share a furnace with the upstairs unit?

Yes, but only if an engineered system is installed to prevent smoke migration between the two units. This typically requires fire dampers within the ductwork triggered by interconnected smoke alarms. Alternatively, we install independent ductless mini-split systems for optimal zonal control and safety compliance.
