A legal basement suite allows homeowners in Calgary to generate rental income, increase property value, and ensure long-term compliance with municipal regulations. Illegal or non-permitted suites can create safety risks and resale complications.
By building a fully legal secondary suite, you protect your investment and ensure your property meets all safety and insurance requirements.
Legal basement suites require multiple permits, including building, electrical, and plumbing permits. Inspections are conducted at various stages of construction to ensure compliance with fire safety, structural integrity, and occupancy standards.
We handle all documentation and coordinate directly with inspectors to streamline the approval process.

We had a great experience! The team was great to coordinate with, and made our basement renovations an easy thing to check off the list. You can tell they've done this many many times, everything ran like a well-oiled machine. 10/10 would recommend!
We could not be happier with Prime Ridge. Not only was the build quality way above expectations, the Project Manager (Burhan) was exceptional with customer service. She would answer in less then half an hour and resolve any question we had.
Prime Ridge is an amazing team that care about their clients. They build things the right way and always strive for high quality! They were sharp and helped identify little things that would otherwise have gone unnoticed. Shout out to the team!
