How long does basement finishing take?

Timeline Overview

Basement finishing typically takes 4-8 weeks in Ottawa, depending on the size, complexity, and whether you're adding a bathroom or kitchen. A basic 600-800 square foot recreation room might be completed in 4-5 weeks, while a full secondary suite with bathroom and kitchenette can take 6-8 weeks or more.

The timeline depends heavily on permit approval, which adds 2-4 weeks to the front end of your project. In Ottawa, building permits for basement finishing typically take 10-20 business days for straightforward projects, but can extend to 4-6 weeks if structural changes or secondary suite conversions are involved.

Factors That Affect Timeline

Project scope is the biggest variable. A simple drywall and flooring job moves much faster than a project requiring electrical upgrades, plumbing rough-in, or structural modifications. Adding a bathroom to your basement can add 1-2 weeks due to plumbing complexity and the need for proper drainage systems - especially important in Ottawa's clay soil conditions.

Inspection schedules also impact timing. The City of Ottawa requires inspections at key milestones (framing, electrical rough-in, insulation, final), and booking these typically adds 2-3 days between phases. During busy construction seasons (spring through fall), inspection delays can stretch longer.

Material availability has improved since pandemic shortages, but specialty items like custom millwork or specific flooring can still cause delays. Weather can also factor in - while basement work happens indoors, material deliveries and any exterior access work (like egress windows) are weather-dependent in Ottawa's climate.

Typical Phase Breakdown

The first week typically involves demolition, framing, and rough electrical/plumbing. Weeks 2-3 cover insulation, drywall installation, and first coats of mud and primer. Weeks 4-5 include flooring installation, trim work, and fixture installation. Final week focuses on painting touch-ups, final electrical connections, and cleanup.

For secondary dwelling units, add extra time for fire separation requirements (45-minute rated assemblies between units), separate entrance construction, and additional City of Ottawa inspections specific to rental unit compliance.

Planning Your Project

Book early - experienced contractors in Ottawa typically have 4-8 week lead times before starting. Winter months (December-March) often have shorter wait times and can be ideal for basement work since it's unaffected by weather.
