Basement Renovations — Westboro, Ottawa
Basement Renovations in Westboro
Westboro basements are often low, so lowering the floor or underpinning is common before a finish is worthwhile.
The short answer
Magnolia Construction finishes and renovates basements in Westboro and across Ottawa — rec rooms, bedrooms with egress windows, bathrooms, wet bars, home theatres and legal secondary units — starting with moisture control and insulation so the space stays warm and dry. A full basement finish with a bathroom typically takes about 10 to 14 weeks.
Most Westboro renovations are constrained by the lot before they are constrained by anything else. Material deliveries, site storage, dust control and neighbour relations all have to be planned, not improvised.
The original houses are small by modern standards, so the brief is usually about volume: opening the main floor, digging out or underpinning the basement, adding a second storey, or building straight back.

Local permits
Narrow Westboro lots frequently trigger setback and lot-coverage limits, and some projects need a minor variance from the Committee of Adjustment. We flag that risk at the first meeting, not after the drawings are done.
Basement lowering and finishing in Westboro
Gaining headroom in older basements, then finishing them as living space rather than storage.
Cost guide
What affects the cost of a basement renovation in Westboro?
Every home is different, so we quote from a site visit rather than a price list. These are the factors that move the number most.
Moisture & foundation
Any water issues, cracks or grading problems are resolved first; that work varies by home.
Bathroom
Using an existing rough-in costs much less than cutting the slab or adding an ejector pump.
Egress windows
A legal bedroom needs a code-compliant egress window, which means excavation and cutting the foundation.
Ceiling height
Low basements may need ductwork rerouted, or in older homes, underpinning or lowering the floor.
Secondary units
A legal suite adds fire separation, a separate entrance, a kitchen and its own permit requirements.
Feature rooms
Wet bars, wine cellars, theatres and custom millwork add scope beyond a standard finish.

Permits
Permits for a basement renovation in Ottawa
Finishing a basement in Ottawa generally requires a building permit, particularly when adding bedrooms, bathrooms or a secondary dwelling unit. Bedrooms need code-compliant egress windows and smoke and CO alarms. We prepare drawings, pull permits and book every inspection.
Common mistakes to avoid
- Framing and drywalling before moisture and grading problems are fixed.
- Adding a bedroom without a code-compliant egress window.
- Skipping the permit, which can cause problems at resale or with insurance.
- Boxing in shut-off valves, cleanouts and the electrical panel with no access.
