Basement Development
AM Builders develops basements into fully livable space for homeowners across Calgary, Airdrie, Chestermere, and Cochrane. A finished basement is one of the most cost-effective ways to add real square footage to an existing home — a second living room, a home office, a guest suite, or a legal secondary suite — without the cost or disruption of an addition. Because basement development touches framing, electrical, plumbing, and often egress windows, it falls under the Alberta Building Code and requires a building permit in every municipality we serve. Our team handles design, permitting, and construction as one coordinated process, so the finished space is safe, comfortable, and built to last.
Our Process
- 1
Consultation & Site Assessment
We walk your basement to assess ceiling height, moisture conditions, existing mechanical and electrical systems, and egress options before any design work begins.
- 2
Design & Permit Drawings
We lay out the space around how you'll actually use it, then prepare the permit-ready drawings your municipality requires for approval.
- 3
Framing, Rough-Ins & Insulation
Framing, electrical, plumbing, and HVAC rough-ins go in to Alberta Building Code standards, followed by insulation and vapour barrier appropriate for below-grade space.
- 4
Inspections
Municipal inspectors sign off on framing and rough-in work before we close up any walls, keeping the project on the right side of code at every stage.
- 5
Finishing & Walkthrough
Drywall, paint, flooring, trim, and fixtures bring the space together, and we complete a final walkthrough with you before handoff.

Frequently Asked Questions
Do I need a permit to develop my basement in Calgary?
Yes. Basement development requires a building permit in Calgary, Airdrie, Chestermere, and Cochrane whenever the work involves framing, electrical, plumbing, or a bedroom egress window. AM Builders prepares and submits the permit drawings as part of every basement project.
How long does a typical basement development take?
Most basement developments take roughly 8 to 12 weeks from permit approval to final walkthrough, depending on the size of the space, the scope of the layout, and inspection scheduling with your municipality.
Do basement bedrooms need an egress window?
Yes. The Alberta Building Code requires a code-compliant egress window in any basement room used as a bedroom, sized to allow for emergency exit. We assess egress options during the initial site visit and include any required window work in the design.
Can I add a bathroom or a secondary suite in my basement?
In most cases, yes. Adding a bathroom is a standard part of many basement developments. A legal secondary suite is also possible but involves additional requirements around ceiling height, parking, and separate egress — we'll tell you upfront whether your basement qualifies.
What affects the cost of a basement development?
Cost is driven by the size of the space, the complexity of the layout, whether a bathroom or wet bar is included, and the finishing level you choose for flooring, trim, and fixtures. We provide a detailed, itemized estimate before any work begins so there are no surprises.
