Common Questions

Frequently Asked Questions

How much does basement development cost in Calgary?

Costs vary based on size, layout complexity, and finish level. A basic finished basement typically starts around $30-$50 per square foot, while a full legal suite with separate entrance, kitchen, and bathroom can range from $60-$100+ per square foot. We provide detailed, transparent quotes during our free consultation so there are no surprises.

Do I need a permit for basement development in Calgary?

Yes. The City of Calgary requires development and building permits for basement development, especially if you're creating a secondary suite. Permits ensure your project meets safety codes for fire separation, egress, electrical, and plumbing. We handle the entire permitting process for you, including coordinating all required inspections.

How long does a basement development project take?

A typical basement development takes 6-12 weeks from start to finish, depending on scope and complexity. A basic finish may take 6-8 weeks, while a full legal suite with plumbing, electrical, and a separate entrance can take 10-12 weeks. Permit approval timelines from the City of Calgary can also affect the schedule.

Can I build a legal basement suite for rental income?

Yes, and it's an excellent investment. Calgary allows secondary suites in most residential areas. We build fully code-compliant suites with separate entrances, fire-rated separations, proper egress windows, independent HVAC, and all required safety features. A legal suite can generate significant monthly rental income and increase your property value.
