Scope of work

Legal secondary suite requirements

Permits, Suites and Rental Income in Calgary

Calgary allows secondary suites in many residential zones, and a legal suite is one of the few renovations that both adds usable space and produces monthly income. The trade-off is a stricter build: egress, fire separation, sound assemblies, alarms and ventilation all have to be right, and each stage is inspected.

We prepare the drawings, submit the permit application and coordinate inspections so the suite is registered rather than unofficial — which matters for insurance, resale and financing. If you are comparing numbers first, read our Calgary basement development cost guide or our main basement development services page.

How a Calgary Basement Project Runs, Step by Step

Step 1

Free in-home consultation

We measure the space, review mechanical locations and talk through how you want to use the basement.

Step 2

Layout and written estimate

You receive a layout concept plus a written estimate listing materials, allowances and included work.

Step 3

Permits and drawings

For suites, bedrooms and structural changes we prepare drawings and coordinate the City of Calgary application.

Step 4

Framing and rough-ins

Framing, electrical, plumbing and HVAC rough-ins are completed and inspected before anything is closed in.

Step 5

Insulation, drywall and finishing

Insulation, drywall, paint, flooring, trim, doors and fixtures are installed in sequence.

Step 6

Final inspection and walkthrough

We complete final inspections, review the finished space with you and hand over warranty details.

Cost depends on square footage, how many bathrooms you add, whether a kitchen or kitchenette is included, and whether the basement is being built as a legal secondary suite. A partially finished rec-room space is far less than a full suite with egress windows, sound separation and a second kitchen. We provide a written estimate after seeing the space so the number reflects your actual basement rather than a generic per-foot figure. Our Calgary basement development cost guide explains what drives the range.

 

Yes. Development permits and building permits are required for finishing a basement in Calgary, and additional approvals apply when you add bedrooms, plumbing or a secondary suite. We prepare the drawings, submit the application and coordinate the inspections as part of the project.

 

In most cases yes, provided the basement can meet ceiling height, egress, separate entrance, fire separation and alarm requirements. We assess feasibility during the consultation and tell you honestly if the space cannot be made compliant.

 

A straightforward development typically runs six to ten weeks on site once permits are issued. Legal suites take longer because of extra inspections and additional assemblies. Permit timelines are set by the City and are confirmed during planning.
Yes. Any new below-grade bedroom needs a compliant egress window, which usually means cutting the foundation and installing a window well. We complete that work, including the concrete cutting and exterior restoration.
