What drywall does a legal secondary suite in Calgary need?

A fire separation (typically Type X) between the suite and the main dwelling on the party wall and floor-ceiling assembly, sound separation for livability, moisture-resistant board in wet areas, and standard board finished to Level 4 elsewhere.

Do I need soundproof drywall in a secondary suite?

Sound separation between the suite and the main floor is increasingly part of Calgary suite requirements and is important for comfort. We build it as a full assembly with insulation and decoupling, not just one special board.

How long does legal suite drywall take?

A typical 600–900 sq ft basement secondary suite is usually 3–5 days: about a day boarding, then mud coats with dry time between, then sanding and finishing. We give a specific schedule on the site visit.

Do you work around inspection hold points?

Yes. Suites have inspections that must happen before drywall closes in walls. We coordinate our start so we are not covering work that still needs inspection, avoiding costly re-opening.

Is suite drywall just basement drywall?

No — a suite adds fire and sound separations that must be built as complete, correct assemblies to pass inspection and be livable for two households. That is the key difference from an ordinary basement.

Do you cover all of Calgary for legal suite drywall?

Yes — all four Calgary quadrants, Airdrie, Cochrane, Okotoks and surrounding communities, 7 days a week, excluding downtown high-rise towers.

What affects the cost of legal suite drywall in Calgary?

Suite size, separations and board spec

Legal suite drywall cost in Calgary depends on the suite size, the separations required (fire-rated party wall and floor-ceiling assembly, sound separation), and the board spec — Type X on the fire separation, moisture-resistant in wet areas, soundproof on the party assembly, standard elsewhere. These assemblies cost more than ordinary basement boarding, which is why a suite is priced as a suite, not a generic basement.

Drywall scope only

We do the drywall portion. The permit, framing, electrical, plumbing and mechanical are your general contractor's responsibility. Pricing the drywall cleanly — boarding, the rated assemblies, taping and finishing — lets you budget the suite accurately.

Coordination with inspections

Suites have inspection hold points before drywall can close in walls. We coordinate our start so we are not covering work that still needs to be inspected, which avoids costly re-opening later.

Our Calgary legal suite drywall process, step by step

Map the rated assemblies first

We start by confirming where the fire separation and sound separation go — typically the wall and floor-ceiling assembly between the suite and the main dwelling — and where moisture-resistant board is needed. Building the right assembly in the right place is what gets the suite through inspection.

Board, fire and sound assemblies, then finish

We board the suite with the correct product on each surface, build the fire-rated separation to the Type X spec and the sound separation as a full assembly with insulation and decoupling, then tape, mud and finish to a clean Level 4 ready for paint.

Work around the build sequence

We coordinate with your GC and the trades, and around inspection hold points, so the drywall goes in at the right time and the suite keeps moving toward approval and occupancy.

Drywall requirements for a Calgary secondary suite

Fire separation

A legal secondary suite requires a fire separation between the suite and the main dwelling — typically Type X fire-rated board on the party wall and the floor-ceiling assembly. The rating only holds when the board, seams and penetrations are done correctly, so the finishing is part of the rated assembly.

Sound separation

Sound separation between the two units is increasingly part of suite requirements and is essential for livability. We build it as a real soundproofing assembly — insulation, decoupling and the right board — not a single product.

Moisture-resistant and standard board

Suite bathrooms and laundry get moisture-resistant board; the rest of the suite uses standard board finished to Level 4. We specify and install each correctly.

Legal suite drywall work we do across Calgary

Basement secondary suites

Most legal suite drywall in Calgary is basement secondary suites — both new builds and conversions of existing basements. This pairs directly with basement development, with the added fire and sound assemblies a legal suite requires. We do this work across established communities like Silver Springs, Ranchlands, Hawkwood and Dalhousie where suite conversions are common.

New-build and backyard suites

In newer communities like Evanston, Mahogany, Walden and Nolan Hill, the work is suites planned into new builds. We also do the drywall scope for garden and garage suites. In every case we build the rated assemblies to spec and finish clean.

Why suite drywall is different from a basement

It is the assemblies, not just the board

An ordinary basement just needs to be boarded and finished. A legal suite adds fire and sound separations that have to be built as complete, correct assemblies to pass inspection and to be livable for two households. That is the real difference, and it is where suite drywall earns its cost.

Inspection is unforgiving

A suite separation that uses the wrong board, has untaped seams or untreated penetrations will fail inspection, and fixing it after the fact is expensive. We build it right the first time so the suite passes and stays on schedule.

Why Calgary homeowners trust Emplastrum for legal suite drywall
