What do Calgary basement inspectors look for during final inspection?

The final basement inspection in Calgary is a comprehensive review by a Safety Codes Officer who verifies that all work matches your approved plans and meets the Alberta Building Code before you can occupy the space. This is the last inspection in the sequence, and the SCO will look at everything from life safety systems to finish quality — but their primary focus is always on safety, structural integrity, and code compliance.

Smoke and CO detectors are one of the first things the inspector checks, and they're one of the most common reasons for a failed final inspection. Your basement must have interconnected smoke detectors outside all sleeping areas and inside every bedroom, with CO detectors on every level that has sleeping areas or fuel-burning appliances. The detectors must be hardwired with battery backup and interconnected so that all alarms sound when any single detector is triggered. The inspector will test the interconnection — if pressing the test button on the basement detector doesn't trigger the upstairs detectors, you'll fail.

Egress windows in all basement bedrooms are critically inspected. The SCO will measure the unobstructed opening to confirm it meets the minimum 3.77 square feet with a minimum width of 15 inches and maximum sill height of 39 inches from the finished floor. The window must be operable without tools or special knowledge, and the window well must be large enough to allow escape. If you labelled a room as a bedroom on your plans, it must have a compliant egress window — no exceptions.

The inspector will verify that all electrical work is complete and safe. This includes confirming that the electrical panel is properly labelled, all outlets are covered with plates, GFCI protection is installed in the bathroom and within 1.5 metres of any sink or wet area, all light fixtures are secured, and the bathroom exhaust fan is properly wired and vented to the exterior — not into the ceiling cavity or attic space. The exhaust fan must provide a minimum 50 CFM of airflow.

Plumbing fixtures in basement bathrooms are checked for proper installation, including secure mounting, functional shut-off valves, proper drainage (no standing water or slow drains), and adequate ventilation. The inspector will confirm that the sump pump is accessible and functional — never sealed behind a finished wall. Floor drains must remain accessible and not covered by finished flooring.

The SCO will examine the overall construction quality — drywall should be properly finished with no exposed insulation or vapour barrier, doors should close and latch properly, handrails on stairs must meet height and graspability requirements, and all framing must be covered. If your project includes a secondary suite, the inspector will pay particular attention to fire separation details, including fire-rated door assemblies with self-closers, sealed penetrations through the fire-rated ceiling, and proper fire blocking.

Ceiling height is measured at the final inspection to confirm compliance — minimum 6 feet 5 inches in existing homes under the Alberta Building Code. The inspector measures at bulkheads, beams, and ductwork enclosures where height is most restricted. If any area drops below the minimum, it either cannot be habitable space or must be modified.

Passing the final inspection means you'll receive a completion certificate from the City of Calgary, which is your proof that the work was done legally and to code — an invaluable document when you eventually sell.
