Basement Development

The floor you already paid for.

Legal suites, home theatres and gyms — finished spaces that add real value to the house rather than square footage nobody uses.

Renovation service

A legal suite and a finished basement are not the same job.

Developing a basement for your own family is a straightforward build. Making it a legal secondary suite brings in egress windows, ceiling heights, fire separations, sound ratings and a separate entrance — and it is worth knowing which one you are buying before drawings start. We price both honestly and tell you what your basement can actually support.

  • Legal secondary suites built to Calgary requirements
  • Egress windows, window wells and separate entrances
  • Fire separations, sound ratings and interconnected alarms
  • Home theatres, gyms, offices and guest suites

What's included

What a basement development includes.

Every project is scoped and priced before we start.

Feasibility

Ceiling height, existing services and whether a legal suite is possible at all.

Permits & drawings

Submitted and followed through the city, not handed to you as homework.

Structure & egress

Window cutting, wells, beams and posts where the layout needs them.

Services

Heating, electrical and plumbing rough-ins sized for the finished use.

Insulation & sound

Warm floors, quiet ceilings and separations that pass inspection.

Finishing

Kitchenette, bathroom, flooring and trim to the same standard as upstairs.

How it runs

How the work runs.

Walkthrough and brief

We see the space, hear what you want and tell you honestly what is realistic for the budget you have in mind.

Design and selections

Drawings, materials and finishes agreed and priced before demolition — not chosen under pressure halfway through.

Permits and schedule

Permits submitted and followed through, trades booked in the order the build actually needs them.

Build, clean

Dust barriers, floor protection and a swept site every night, because you are usually still living in the house.

Walkthrough and warranty

We walk it with you, fix the list, and hand over the warranty paperwork. Your sign-off is what ends the job.

Legal suite or finished basement

Decide which one you are building before drawings start.

Finishing a basement for your own family and building a legal secondary suite are different projects with different budgets. A suite brings egress windows, minimum ceiling heights, fire separations between dwellings, sound ratings, interconnected alarms, its own heating and often a separate entrance — and every one of those is far cheaper designed in than added afterwards.

Some basements simply cannot carry a legal suite: the ceiling is too low, or there is nowhere to put an egress window, or the parking the district requires is not there. We tell you that at the walkthrough rather than after you have paid for drawings.

  • Ceiling height measured against the minimum before anything is designed
  • Egress window and well sized, and the wall opened to take it
  • Fire separation, sound rating and interconnected alarms between dwellings
  • Separate entrance, heating and metering where the suite needs them

Common questions

Questions we get asked most.

Anything not covered here, just ask on the call.

How do I know if my basement can be a legal suite?

The quick tests are ceiling height, whether an egress window can be cut and welled, and whether the district permits a secondary suite at that address with the parking available. We check all three at the first walkthrough, free, before anyone spends money on design.

How long does a basement development take?

Six to ten weeks for a straightforward development. A legal suite runs longer — allow for permits ahead of the work and for the inspections that come with the fire separation and the egress window.

Will a basement suite be cold?

Not if it is insulated and heated properly. Below-grade walls need continuous insulation and a vapour control layer done correctly, and the suite needs heating sized for it rather than borrowed from the floor above. Cold basements are a build problem, not a basement problem.

What about the ceiling height around the ducts?

Bulkheads around ducting and beams are normal, but they must not drop below the required clear height in the habitable areas. Where it is tight, we look at rerouting or flattening ductwork before accepting a layout that fails inspection.
