FAQs
Frequently Asked Questions
What are the emergency access requirements for a garden suite?
For a garden suite to be approved, there must be a clear path for emergency access. This typically requires a minimum width of 0.9 to 1.0 metres from the flanking or public street to the suite entrance. We also ensure that your design includes the required safety features, such as an exterior strobe light, to meet the relevant fire safety criteria.
Can I include a basement in my garden suite?
Yes, you can include a basement in your proposed construction. This is an excellent way to increase the total floor area of a secondary suite without exceeding the maximum rear-yard lot coverage allowed. StrongBuilds provides the structural engineering for safe basement excavations near your principal dwelling.
How long does the permit application process take?
Once the building permit drawings are submitted to the building department, the permit review process typically takes 10 to 14 business days for the initial response. Larger or more complex infill housing projects may take 4 to 6 weeks for a full review.
Do I need separate services for my lane or garden suite?
In many jurisdictions, an additional dwelling unit may require separate plumbing and electrical connections from the main house. We help you confirm compliance with local rules regarding separate services and fire separation during the design phase.
