In Ottawa, whole-house renovations typically cost $80 to $300+ per square foot in 2026, with most homeowners landing between $125 and $200 per square foot for a solid mid-range refresh. A cosmetic update — paint, flooring, lighting, and minor fixtures — usually runs $80–$125 per square foot, a mid-range renovation with new kitchen and bathroom finishes runs about $125–$200, and a full gut down to the studs with new mechanicals, insulation, and layout changes commonly hits $200–$300+ per square foot. On a 1,800 sq ft two-storey in Ottawa, that translates to roughly $145,000–$360,000 for a mid-r...

Ottawa Renovation Cost Per Square Foot by Scope (2026)

Per-square-foot pricing only makes sense once you define scope, because the same 1,500 sq ft house can be a $120,000 job or a $400,000 job. In 2026 Ottawa dollars, a cosmetic-level renovation — repainting, replacing flooring, swapping light fixtures, refinishing or refacing cabinets, and updating hardware — runs roughly $80–$125 per square foot. A mid-range renovation that includes a new kitchen, one or two updated bathrooms, new flooring throughout, trim, doors, and some electrical upgrades typ...

Sample Ottawa Budgets by Home Size

A 1,200 sq ft bungalow: about $96,000–$150,000 cosmetic, $150,000–$240,000 mid-range, $240,000–$360,000 gut. A 1,800 sq ft two-storey: about $144,000–$225,000 cosmetic, $225,000–$360,000 mid-range, and $360,000+ for a full gut. A 2,500 sq ft home at mid-range finishes commonly runs $310,000–$500,000...

What Drives the Price Up or Down in Ottawa

The biggest cost multiplier is mechanical work. The moment a renovation moves plumbing stacks, adds circuits, or reroutes ductwork, you add licensed trades, permits, and inspections — and per-square-foot costs jump 30–60 percent over a finishes-only job. Structural changes are next: removing a load-bearing wall to open a kitchen to a living room typically adds $4,000–$12,000 in Ottawa once you include an engineer's letter, a steel or LVL beam, temporary shoring, and the permit. Home age matters ...

The Ottawa Contingency Rule

Budget a 15 percent contingency on a cosmetic renovation and 20 percent on anything that opens walls. In Ottawa's older housing stock, unexpected findings behind the drywall are the norm, not the exception, and an underfunded contingency is what turns a renovation into a stalled project.

Cost Per Square Foot by Room

Blended whole-house numbers hide the fact that renovation cost is wildly uneven room to room. Kitchens are the most expensive space in an Ottawa home, commonly running $300–$700 per square foot when you factor cabinets, counters, appliances, plumbing, and electrical — a 150 sq ft kitchen at mid-range finishes typically lands at $45,000–$75,000 in 2026. Bathrooms are similarly dense: $350–$800 per square foot, meaning a standard 40 sq ft main bathroom runs about $16,000–$30,000 and a primary ensu...

Permits, Inspections, and Ottawa's Older Housing Stock

Most renovations that involve structural changes, new plumbing fixtures, new circuits, HVAC replacement, or finishing a basement require a City of Ottawa building permit, and electrical work requires a separate ESA notification and inspection regardless of the building permit. Permit fees for residential renovation work in Ottawa are typically a few hundred to a couple of thousand dollars depending on the value and scope of work, but the real cost of skipping them shows up at resale or at insura...

Where Permits Actually Save Money

Permitted work gets inspected, and inspections catch framing, venting, and wiring problems while they are still cheap to fix. Unpermitted renovations discovered during a home sale often need to be opened back up and redone — the most expensive way to do any job twice.

How to Control Your Cost Per Square Foot

The most effective way to lower per-square-foot cost is to keep plumbing and load-bearing walls where they are. Reusing existing drain locations in a kitchen or bathroom can save $3,000–$10,000 per room. The second lever is phasing: doing the kitchen this year and bathrooms next year spreads cash flow, although it does cost more in total than a single mobilization because you pay for setup, dust protection, and trade scheduling twice. Third, decide finish levels early and lock them in — change o...
