Basement Electrical Wiring & Finishing in Ottawa

A basic rec room with outlets, lighting, and one or two dedicated circuits runs $3,500 to $5,000 in Ottawa. A full basement apartment with kitchen, bathroom, bedroom, and separate entrance runs $5,000 to $8,000. Sub-panel installation adds $800 to $1,500 depending on amperage and distance from the main panel. Homes in Westboro and Hintonburg with older 100-amp panels often need sub-panels to handle basement load. Newer homes in Kanata and Barrhaven usually have enough panel capacity for a standard rec room. The biggest cost variables are square footage, number of rooms, and whether a sub-panel is needed. We give you a written price after assessing the job — before any work starts.

If a permit is needed, we handle the paperwork and scheduling with the ESA. You don't need to contact anyone or track deadlines. Our electricians work under a master electrician's licence, which authorises this type of installation in Ontario. The ESA inspects rough-in wiring before the walls close and signs off on the final installation after outlets and fixtures are in place. Most Ottawa homeowners don't need to think about permits — we manage the process from application to inspection sign-off.

A basic rec room needs at least two 15-amp circuits for general outlets and one dedicated lighting circuit. Each bedroom needs its own outlet circuit and dedicated lighting. Bathrooms require a dedicated 15-amp circuit for GFCI outlets. If you're adding a kitchenette or wet bar, expect two dedicated 20-amp circuits for countertop outlets plus separate circuits for the fridge and microwave. Electric baseboard heaters each need their own 240-volt circuit. Older Ottawa homes in Nepean and Gloucester often need sub-panels to handle the additional circuits without overloading the main panel. We calculate the total load during the assessment and size the circuits correctly for what you're adding.

GFCI protection is required for any outlet within six feet of a water source — bathroom sinks, laundry sinks, wet bars, and utility sinks. In Ontario, all basement bathroom outlets must be GFCI protected regardless of distance from the sink. Standard 15-amp outlets are used in dry areas like rec rooms, bedrooms, and hallways. GFCI outlets prevent shocks in areas where water and electricity might come into contact. We install GFCI outlets where the code requires them and explain the placement during the walkthrough.

A sub-panel makes sense if your main panel is full, if you're adding more than four or five new circuits, or if the basement is a long distance from the main panel. Older Ottawa homes built before 1990 — especially in Westboro, Hintonburg, Vanier, and parts of Nepean — typically have 100-amp main panels with limited breaker slots. Adding basement circuits to these panels often requires a sub-panel to avoid overloading the main service. Newer homes in Kanata, Barrhaven, and Orleans usually have 200-amp panels with room for basement circuits without a sub-panel. We assess your panel capacity during the quote and recommend a sub-panel only when it's necessary. A 60-amp sub-panel handles most basement renovations and costs $800 to $1,500 installed depending on wire run length.

Yes. Rough-in wiring happens after framing is complete and before insulation and drywall. We install all outlet boxes, switch boxes, junction boxes, and wiring during this stage. The rough-in must pass an ESA inspection before the drywall crew closes the walls. We coordinate timing with your general contractor to ensure the rough-in doesn't delay the build schedule. Most rough-ins for a rec room take one to two days. A full basement apartment takes three to four days depending on the number of rooms and dedicated circuits. We tell you the expected duration during the assessment so your contractor can schedule around it.

Rough-in for a basic rec room takes one to two days. A full basement apartment with kitchen, bathroom, bedroom, and living area takes three to five days for rough-in plus another day for final installation after drywall and paint are complete. If a sub-panel is needed, add one day for that installation. The timeline depends on square footage, number of rooms, and whether we're tying into an existing panel or installing a new sub-panel. Older Ottawa homes in Hintonburg and Westboro sometimes require additional grounding work, which can add half a day. We give you a clear timeline during the assessment so you can plan the rest of the renovation around the electrical work.

Yes. We communicate directly with your general contractor or framing crew to schedule rough-in once framing is complete. The rough-in must be inspected before insulation and drywall, so timing matters. We confirm the inspection date with the ESA and notify your contractor when the walls can be closed. Final installation — outlets, switches, fixtures, and cover plates — happens after drywall and paint are finished. Most contractors prefer to work with electricians who coordinate timing without delays. We've completed basement renovations across Ottawa for 15 years and know how to fit into the build schedule without slowing down other trades.
