Basement Development in Calgary & Okotoks

What's Included in a Parkside Basement Development

Basement developments are the most multi-trade renovation we deliver. A single basement build typically involves nine separate trades: framing, electrical, plumbing, gas (often), HVAC adjustments, insulation, drywall, painting, tile, carpet/vinyl/hardwood, and finishing carpentry, plus the inspections that go with each. Coordinating those trades around a single schedule, with proper sequencing and minimal idle days, is most of the work of running a basement project well.

Our scope includes all of the above. We handle layout design, permit submission, framing (we use 2x4 walls on dimpled membrane or sleepers depending on the slab condition), electrical rough-in (typical Calgary basements need a sub-panel addition or at least four to six new circuits), plumbing rough-in (including any required slab break-out and concrete repour), HVAC adjustments (additional cold-air returns and supplies are almost always required), insulation (we recommend Roxul batt over fibreglass for sound and moisture performance), drywall, taping, paint, finished flooring, doors, trim, and hardware.

Our Basement Development Process

1. Site visit and concept layout

We measure the basement, locate the existing rough plumbing, identify the support columns, mark the windows, and sketch a layout that works. Common Calgary basement layouts include one or two bedrooms, a bathroom or two, an open rec room, a flex room (gym, office, music room), storage, and often a wet bar or kitchenette.

2. Permits and detailed design

Once you approve the concept, we produce dimensioned drawings, submit for a building permit, and order the long-lead items: usually doors, windows (if egress changes are needed), and any custom millwork. The City of Calgary permit timeline runs 4 to 8 weeks depending on the queue; the Town of Okotoks is generally faster.

3. Construction phases

Framing first, then plumbing rough-in (including any slab break-out), then electrical and gas, then HVAC, then insulation. The four rough-in trades each get an inspection before drywall closes the walls. Drywall, tape, prime, paint. Then the second-trim phase: doors and casing, baseboards, electrical fixtures, plumbing fixtures, tile in the bathroom, flooring, vanities and counters. Final inspection and walkthrough.

4. Final walkthrough and warranty

We test every outlet, every faucet, every drain, every door, every smoke alarm, and every interconnected CO detector. Punch-list items get resolved before sign-off, not after.

Common Basement Projects We Handle

• The standard one-bedroom builder basement. Cranston, Auburn Bay, Mahogany, McKenzie Towne, and Legacy basements built between 2005 and 2018 typically have a rough-in for one bathroom and standard 8-foot ceilings. The classic build is one bedroom, one bathroom, an open rec room, and storage. 10 to 12 weeks, $55-80k.
• The two-bedroom family basement with wet bar. Okotoks homes built in the 2000s often have full-height basements with usable window wells. Two bedrooms (one converted to office), a full bathroom, a rec room with a TV wall, and a small wet bar is the most-built configuration we deliver in Okotoks.
• The legal secondary suite retrofit. Bridgeland, Killarney, Renfrew, and Sunnyside infills frequently include legal secondary suites at construction. We've completed several retrofits (converting an existing basement into a permit-compliant legal suite) which is a more complex project requiring egress, sound separation, separate mechanical, and a development permit.
• The walk-out as second main floor. Heritage Pointe and De Winton walk-out basements with full-height ceilings and large windows are some of our favourite projects to design. The basement effectively becomes a second main floor (full kitchen, primary suite, family room) and the work involves more glass, more lighting design, and more millwork than a standard build.
• The home gym + theatre. An increasing number of clients are converting basement rec rooms into a combined home gym and home theatre. The build involves rubber flooring in the gym zone, 5.1 or 7.1 wiring in the theatre, blackout treatment, and dedicated electrical for any heavy equipment.

What Calgary Building Code Requires

Every basement development we deliver meets the Alberta Building Code and the City of Calgary's local amendments. The most-impactful requirements: bedrooms must have egress windows of the correct size and placement; smoke alarms must be hardwired and interconnected with the rest of the home; a CO alarm is required within 5 m of any sleeping room; bathroom fans must be ducted to the exterior; insulation must meet effective R-values for below-grade walls; and stairways must have proper handrails and rise/run dimensions. We carry checklists for all of this and our framing and rough-in walks confirm everything before drywall closes the wall.

Service Area

We deliver basement developments across Calgary (all quadrants), Okotoks, Airdrie, Cochrane, Chestermere, High River, Heritage Pointe, De Winton, Priddis, Bragg Creek, Black Diamond, Turner Valley, and Strathmore. Acreage developments outside city limits often have additional septic and well considerations; we handle those as part of the project planning.
