A single major renovation budget is the most common kind we quote in Ottawa. It's the level where homeowners can finance with a HELOC or a refinance, where the math still works against the home's after-renovation value, and where the project scope feels meaningful but not overwhelming. The question homeowners always ask is what that budget actually buys.
The honest answer: it buys exactly one of three major scopes. You don't get to do all three at once. The smart move is to understand what drives the cost of each, then pick the one that fits your home and your goals.
Option A: Full kitchen + 1 bathroom + flooring + paint
The cosmetic-and-mechanical refresh of the existing house. No walls move. No additions. The bones stay. The finishes get fully replaced.
What this scope covers on a 2,200-2,400 sq ft Ottawa home:
- Full kitchen renovation: new cabinets (typically Shaker-style or flat-front in white or two-tone), quartz counter, mid-range appliance package (Bosch or KitchenAid), tile backsplash, undermount sink, new faucet, new lighting
- Primary bathroom renovation: new vanity (typically 60" double-sink), tile shower with glass enclosure, new toilet, freestanding tub if space allows, heated floor on the small wet area
- All flooring replaced: engineered hardwood throughout main floor and bedrooms (about 1,800 sq ft), tile in wet areas
- Full house paint: walls, ceilings, trim, doors, two coats throughout
- New interior doors and trim: solid-core doors, baseboards, casing
- Light fixture and lighting upgrade
- Minor electrical: some new circuits, new switches and receptacles
- Permit, project management, contingency: carried as named line items in the written proposal
What this doesn't include: secondary bathrooms (powder room, kids' bath stay as-is), basement, exterior, HVAC, no walls moving, no panel upgrade, no kitchen relocation.
Best fit: homes built 1990-2010 where the layout works but every finish looks dated. Common in Barrhaven, Kanata, Findlay Creek, Stittsville, parts of Orleans.
Option B: Rear bump-out + new kitchen
Push the back of the house out 6-8 feet, build a new kitchen in the addition, leave the rest of the house alone.
What this scope covers:
- Bump-out construction (foundation, framing, envelope, mechanical, finish): about 80-130 sq ft of new floor area, the single largest cost driver in this scope
- New kitchen built in the addition: same scope as Option A's kitchen, but in the new space
- Integration with existing house: flooring transition, paint of adjacent rooms
- Permit, drawings, P.Eng: structural design carried as named line items
- Contingency: a held reserve for site conditions revealed once the wall opens
What this doesn't include: bathroom renovation, flooring elsewhere, paint elsewhere, basement, the secondary bathrooms.
Best fit: homes built 1950-1980 where the original kitchen is too small (9 × 11 ft galley) and the rear yard has the depth to push 6-8 feet. Common in Manor Park, Alta Vista, older Nepean, Lindenlea.
Option C: Basement legal suite + ensuite refresh
Convert the basement into a legal second dwelling unit (rental income) and refresh the primary bathroom upstairs.
What this scope covers:
- Legal basement suite: egress windows, separate entrance, full kitchen, 3-piece bathroom, fire-rated separation, sound attenuation, separate HVAC zone, sub-meter or separate panel, finished living area (typically 1 bedroom + living + kitchen + bath). The code-compliance work here is the biggest cost driver.
- Primary bathroom refresh: new vanity, tile shower, toilet, fixtures (lighter scope than full reno)
- Mechanical upgrades to support both: service upgrade if needed, HVAC zoning
- Permit, drawings, contingency: carried as named line items
What this doesn't include: kitchen reno upstairs, main-floor flooring, paint, addition, exterior.
Best fit: homes with unfinished or partially-finished basements with 6'8"+ ceiling height, side door access, and zoning that allows a second unit. Common across most of Ottawa under Bill 23.
Why you can't do all three in one budget
Homeowners ask if a single budget can cover a kitchen, two bathrooms, all flooring, paint, and a small addition. The answer is no, not honestly. Each of the three scopes above carries its own demolition, permits, mechanical work, finishes, and labour, and those costs don't shrink when you bundle them.
The "yes we can do it all" quote you'll see from a low-bid contractor is usually skipping permits, using lowest-grade materials, or planning to recover the gap later through change orders. Our proposals are fixed-price, with BCIN-stamped drawings, mid-range to upper-mid finishes, and a 1-year DTR warranty. The realistic move is to pick one of the three scopes and do it properly.
Combining two, or all three, scales the budget accordingly, and we show you exactly how in the written breakdown.
The hidden costs that strain a renovation budget
Three line items homeowners forget when planning a major renovation:
1. Temporary housing
If the project takes the kitchen offline for 4-6 weeks, you need to plan for meals out, possibly a microwave-and-hotplate setup. If it takes the primary bathroom offline, you're showering at the gym or a friend's place. If it's Option B (bump-out + kitchen), the dust and noise mean some clients rent for 6-8 weeks. These living costs sit outside the construction proposal and should be planned for separately.
2. Furniture and decor
A new kitchen wants new bar stools, a new dining table, new lighting that ties to the new room. Most homeowners refresh furniture and decor in the first 6 months after a kitchen renovation. That spend is yours, not the contractor's, and it isn't in the construction quote.
3. Landscaping touch-up
An addition compacts soil, kills grass under construction routes, leaves debris behind. Re-grading, sod, mulch, and plant replacement are real costs that follow exterior work.
The true cost of ownership on a major renovation runs higher than the construction quote alone once you include the line items that sit outside it. We flag every one of them up front so the budget conversation is complete.
What ROI looks like on each option
The three options have different financial profiles for resale and use:
Option A (kitchen + bath + flooring + paint)
Resale recovery: 75-90% in most Ottawa neighbourhoods. Strong because every buyer values updated finishes. Daily-use value: very high. Time to enjoyment: 12-16 weeks. The classic "stay in your home for 10 more years" project.
Option B (bump-out + kitchen)
Resale recovery: 65-85% depending on whether the new layout is universally appealing. Strong if the kitchen flows well to the dining and living spaces. Weaker if it creates an awkward room. Daily-use value: very high if the existing kitchen was your daily pain point. Time to enjoyment: 14-18 weeks.
Option C (basement suite + ensuite refresh)
Resale recovery: 80-110%, yes, sometimes you make money. A legal income suite adds substantial value through its monthly rent. Daily-use value: depends on whether you actually have or want a tenant. Time to enjoyment: 16-20 weeks (longer permit cycle for legal suites). The investment-focused option.
The renovation that disappoints is the one that tried to do all three at once. The renovation the homeowner loves five years later is the one that picked one priority and did it properly.
How to decide between the three
The decision framework we use with major-budget clients:
- Does the existing kitchen layout work? If yes, Option A. If no, Option B.
- Is the rear yard deep enough for a meaningful bump-out? If yes, Option B is on the table. If no, Options A or C.
- Do you want rental income or accommodation for family? If yes, Option C is your highest-ROI choice.
- Are you planning to sell within 3 years? If yes, Option A or Option C give the best recovery. Option B is more about lifestyle.
- Is the basement legal-suite-eligible (ceiling height, side entrance, zoning)? If no, Option C drops out.
We walk through this exact decision tree on every major-budget consultation. Half the time the homeowner thinks they want Option A and ends up choosing Option C. Half the time the reverse. The point is to actually decide, not split the budget into thirds and end up disappointed with all three.
The bottom line
A major renovation budget in Ottawa buys one of three real scopes: full kitchen + 1 bath + flooring + paint, OR rear bump-out + new kitchen, OR basement legal suite + ensuite refresh. Don't try to do all three. Don't trust the contractor who says you can.

Frequently asked questions
What does a kitchen, bathroom, flooring and paint renovation include?
A kitchen, bathroom, flooring and paint scope replaces the finishes without moving walls. On a 2,200 to 2,400 sq ft Ottawa home it covers a full kitchen with new cabinets, quartz counter and mid-range appliances, a primary bathroom with a tiled glass shower, engineered hardwood across about 1,800 sq ft, two coats of paint throughout, new interior doors and trim, lighting and minor electrical.
Secondary baths, the basement, HVAC and panel upgrades are not included.
Which homes suit a rear bump-out for a bigger kitchen?
A rear bump-out kitchen suits homes built from 1950 to 1980 where the original kitchen is too small, often a 9 by 11 foot galley, and the rear yard has the depth to push the back wall out 6 to 8 feet.
That adds about 80 to 130 sq ft of floor area, which is the largest cost driver in the scope. Manor Park, Alta Vista, older Nepean and Lindenlea have many homes like this.
What does a basement need to become a legal second unit in Ottawa?
A legal basement suite needs egress windows, a separate entrance, a full kitchen, a 3-piece bathroom, fire-rated separation, sound attenuation, a separate HVAC zone and a sub-meter or separate panel. The basement should have ceilings of 6 foot 8 inches or more, side door access and zoning that allows a second unit, which applies across most of Ottawa under Bill 23. The code-compliance work is the biggest cost driver.
Which major renovation gives the best resale return in Ottawa?
A basement legal suite with an ensuite refresh recovers the most at resale, 80 to 110% in Ottawa, because a legal income suite adds value through monthly rent. A kitchen, bathroom, flooring and paint refresh recovers 75 to 90%, since every buyer values updated finishes.
A rear bump-out with a new kitchen recovers 65 to 85%, stronger when the kitchen flows well into dining and living space and weaker when it creates an awkward room.
What renovation costs sit outside the contractor's quote?
Three costs usually sit outside a renovation quote. Temporary living: a kitchen offline for 4 to 6 weeks means meals out or a hotplate setup, and a bump-out's dust and noise lead some households to rent elsewhere for 6 to 8 weeks.
Furniture and decor: most homeowners refresh stools, tables and lighting within 6 months of a new kitchen. Landscaping: an addition compacts soil and kills grass, so regrading, sod and plants follow.
