    Drywall, flooring, and lighting come last, followed by a walkthrough together before we consider the project done.

Planning your project

What to consider before you develop your basement

A few practical things worth thinking about before your consultation.

  1. 01

    Ceiling height affects what's possible

    The City of Calgary sets minimum ceiling height requirements for finished basement space — this gets checked during your free consultation before anything is quoted.

  2. 02

    Egress windows are non-negotiable for bedrooms

    Any bedroom in a finished basement needs a code-compliant egress window for fire escape — if one doesn't already exist, cutting a new opening is a real line item in your quote, not an afterthought.

  3. 03

    Secondary suites have their own requirements

    If the goal is a legal secondary suite rather than just extra living space, that changes the permit, the inspection process, and the Secondary Suite Registry step at the end — worth deciding upfront.

Common questions

Basement finishing FAQs

How much does basement finishing cost in Calgary?

Basement finishing cost depends mainly on total size, layout complexity, and whether a bathroom or secondary suite is included. A simple open rec-room finish costs far less per square foot than a layout with multiple rooms, since each interior wall means more framing, drywall, and doors. Adding a bathroom below grade often means a sewage ejector pump if the drain sits below the main sewer line, and a secondary suite adds permit, egress window, and separate-entrance requirements on top of standard framing and finishing. We provide a fully itemized, fixed-price quote after a free in-home consultation, so you know the exact cost — driven by your specific layout — before work begins.

Do I need a permit to finish my basement in Calgary?

Yes — the City of Calgary requires a building permit for basement development, and a secondary suite requires additional approval. We manage the full permitting process for you.

Can you build a legal secondary suite in my basement?

Yes, we build basement developments to current secondary suite requirements, including egress windows, ceiling height, and separate entrances where required.

How long does a basement finishing project take?

Most basement finishing projects take 6–10 weeks depending on size and whether a bathroom or suite is included.
