A whole-house renovation in Ottawa typically runs $135-$385 per square foot in 2026 depending on whether it is a partial whole-house refresh or a true studs-out gut. The gap is enormous: a partial project keeps the structure, mechanicals and layout largely intact, while a full gut replaces everything behind the walls and often reconfigures the floor plan. This guide gives 2026 Ottawa pricing by home size and scope tier, breaks down cost by home age, details a typical gut cost-allocation, and covers the schedule, move-out budgets and permit stack so you can plan a major project realistically fr...
Four tiers define whole-house pricing. A partial whole-house renovation — kitchen, bathrooms, flooring and paint with no structural change — runs $135-$215/sq ft. A major whole-house renovation that adds HVAC, electrical and some layout changes runs $215-$295/sq ft. A full gut — studs-out, new mechanical, electrical and plumbing, and layout changes — runs $245-$385/sq ft. A heritage gut with structural restoration, common in Sandy Hill, New Edinburgh and Centretown, runs $325-$485/sq ft because ...
Translating per-sq-ft rates into real budgets: a 1,500 sq ft bungalow runs $200K-$325K partial, $325K-$445K major, and $370K-$580K for a full gut. A 2,000 sq ft two-storey runs $270K-$430K partial, $430K-$590K major, and $490K-$770K for a full gut. A 2,500 sq ft home runs $340K-$540K partial, $540K-...
Home age is the strongest predictor of whole-house cost. Pre-1960 homes are the most expensive to gut: knob-and-tube wiring needs full replacement ($15K-$45K), galvanized plumbing needs repiping ($12K-$35K), asbestos abatement is common ($5K-$25K), foundation issues appear often ($10K-$85K), and many are heritage-controlled. Homes from 1960-1990 bring aluminum-wiring remediation ($8K-$22K), original windows due for replacement ($25K-$65K), and aging HVAC ($12K-$25K). Post-2000 homes carry the lo...
On a full gut, costs allocate roughly as follows: demolition 5-8% ($30K-$70K), structural and framing 8-12% ($45K-$105K), roofing 3-5%, windows and doors 8-12%, HVAC 6-10% ($35K-$85K), plumbing 5-8%, electrical 5-8%, insulation and drywall 6-10%, flooring 5-9%, kitchen 12-18% ($65K-$165K), bathrooms 8-12%, and paint and finishes 4-7%. On top of trade costs sit GC overhead and markup at 15-22% and permits and design at 6-10%. Seeing the allocation helps you spot an unbalanced quote — a kitchen li...
Whole-house projects are long. A partial whole-house runs 16-26 weeks, a major whole-house 26-40 weeks, a full gut 36-60 weeks, and a heritage gut 48-72 weeks. Add 8-16 weeks up front for design and permits, more if a Committee of Adjustment variance is involved. Most Ottawa whole-house projects req...
On older or badly configured homes, a tear-down and new build sometimes beats a gut. A mid-range custom new build in Ottawa runs $325-$525/sq ft, and includes a fresh Tarion new-home warranty, modern efficiency, and exactly the layout you want with no compromises around existing structure. As a rule of thumb, when a full gut on a 2,000 sq ft home pushes past about $325/sq ft, demolition and rebuilding often makes more financial sense. The trade-offs are demolition cost, a longer overall timeline...
Renovation keeps the edge when the existing structure is sound, the location and footprint are hard to replicate (a mature-neighbourhood lot with non-conforming setbacks you would lose on a rebuild), or the home has heritage character worth preserving. Phased renovation also lets some owners stay in...
Whole-house renovations expose more unknowns than any other project type, so contingency must scale with scope and age. Use 15% for a partial whole-house, 20-25% for a major renovation, and 25-35% for a full gut — pushing toward the top for pre-1960 Ottawa homes where knob-and-tube, asbestos and fou...
A whole-house renovation pulls the full permit stack. You will need a building permit (mandatory), and likely a demolition permit if major walls come out. Trade permits — electrical through the ESA, plumbing, and HVAC — are required for the systems work. A heritage permit applies in designated districts, and any change to setbacks, lot coverage or unit count can require Committee of Adjustment approval, which adds months. Engineering stamps are needed wherever structure is altered. Reputable Ott...
City of Ottawa building-permit fees on residential alterations are calculated by floor area, running roughly $22-$28 per square metre of work in 2026, with a typical whole-house project landing between $2,500 and $9,000 depending on size and scope. A demolition permit adds a few hundred dollars, and...
Whole-house projects are large enough that financing structure matters as much as the construction estimate. Common 2026 routes in Ottawa include a mortgage refinance that folds the renovation into one payment, a HELOC for flexible staged draws as milestones complete, and the federal Canada Greener Homes Loan for up to $40,000 interest-free toward qualifying energy retrofits — valuable on a gut where you are already opening walls. Some owners use a purchase-plus-improvements mortgage when renova...
Common routes are a mortgage refinance folding the reno into one payment, a HELOC for flexible staged draws, a purchase-plus-improvements mortgage when renovating right after buying, and the Canada Greener Homes Loan (up to $40,000 interest-free) for qualifying energy retrofits. Arrange financing before signing so draws match the contractor's milestone schedule.
2026 ranges: partial $135-$215/sq ft, major $215-$295/sq ft, and full gut $245-$385/sq ft. A typical 2,000 sq ft Ottawa full gut runs $490K-$770K before soft costs and contingency, with heritage guts running higher.
A tear-down and mid-range custom new build runs $325-$525/sq ft. If a full gut on a 2,000 sq ft home exceeds about $325/sq ft, demolition and new construction often makes more financial sense — and you gain a new Tarion warranty, though zoning and demolition costs must be weighed.
A full gut runs 36-60 weeks of construction plus 8-16 weeks for design and permits. Most Ottawa full-gut projects total 12-18 months from contract to move-in. Heritage homes typically add another four to six months for review and careful restoration work.
For a partial whole-house with cosmetic and finish work only, some owners stay through phased work. For a full gut with no working kitchen or bathroom and active demolition, moving out is almost always required — budget $2,200-$4,500/month for rental housing over six to twelve months.
