Frequently asked question
Do you build legal basement suites and secondary suites in Calgary?
Yes — legal basement suites and secondary suites are our specialty. We handle the full project from design and permits through to final city inspection. Every suite we build meets City of Calgary secondary suite requirements, including fire separation, egress windows, separate entrance, and heating and ventilation system. standards.
How much does a legal basement suite or secondary suite cost in Calgary
Legal secondary suites in Calgary typically start at $40,000 and can reach $80,000 depending on basement size, existing conditions, and finish level. Personal basement renovations start at $20,000. You may also qualify for up to $10,000 through the City of Calgary Secondary Suite Incentive Program, which we help you apply for.
If your pricing is affordable, do you cut corners?
How long does a legal basement suite project take
A typical legal secondary suite project takes 6 to 12 weeks from permit approval to final inspection, depending on scope and complexity. Personal basement renovations are generally faster since they don’t require secondary suite permit approvals. We provide a clear timeline before work begins and keep you updated throughout.
Can you convert my existing basement into a legal secondary suite in Calgary?
Absolutely. Most unfinished or informally finished basements can be converted into a fully legal secondary suite. We start with an on-site assessment to evaluate your ceiling height, layout, and existing mechanical systems, then outline exactly what’s needed to bring it up to code. Many Calgary homeowners are surprised by how achievable the conversion is.
What does Calgary require for a legal basement suite or secondary suite?
The City of Calgary requires legal secondary suites to meet specific building code standards, including: a minimum ceiling height of 1.95m (6’5″), a separate entrance, fire-rated separation between the suite and the main home, egress windows in all sleeping areas, independent heating, and proper ventilation. We ensure every one of these requirements is met before final inspection.
Do you help with basement design and layout planning?
Yes. We help you plan a layout that maximizes livable space, meets secondary suite requirements, and fits your budget. For legal suites, we design around Calgary’s code requirements from the start — so nothing needs to be redone later. For personal renovations, we tailor the layout to your lifestyle.
Can I live in my home during the renovation?
In most cases, yes. The majority of our basement renovation and secondary suite projects allow homeowners to remain in the home throughout construction. We keep the work zone contained, maintain a clean site daily, and schedule noisier work during reasonable hours. We’ll let you know upfront if any phase of your specific project requires temporary arrangements.
