The Quick Answer for Ottawa Homeowners
Residential renovation planning comes down to six steps: define the scope in writing, set a budget with a 10–20% contingency, test a pre-1990 home for asbestos, confirm permit requirements, hire a licensed contractor with a written quote, and lock the schedule before demolition. Skipping any one of them is where budgets and timelines fall apart.
The 6-step renovation planning process
1. Define the scope in writing
List every room, every change, and every finish decision before asking for quotes. Two kitchens of the same size can differ in price by tens of thousands of dollars — the scope, not the square footage, sets the number. A written scope also makes quotes comparable between contractors.
2. Set the budget — with a contingency
Use realistic Ottawa ranges (see the table below) and hold back 10–20% for what's behind the walls. In pre-1990 homes, surprises like outdated wiring, galvanized plumbing, or asbestos-containing materials are common enough to plan for. Our guide to avoiding renovation cost overruns covers the most frequent budget breakers.
3. Test before you touch (pre-1990 homes)
If your home was built before 1990, lab-test suspect materials for asbestos before demolition — typically $300–$600. It's a legal requirement under Ontario Regulation 278/05 before disturbing asbestos-containing materials, and finding it early keeps it a line item instead of a work stoppage. See the signs you may need asbestos removal before renovating.
4. Confirm permits early
Structural changes, moved plumbing, basement developments, and most additions need a City of Ottawa building permit; cosmetic updates don't. The City's review typically takes 10–15 business days for a complete residential application — time that belongs in your schedule, not as a surprise.
5. Hire licensed, insured, and in writing
Verify licence and insurance, ask for local references, and get an itemized written quote — never a verbal number. Our guide on how to choose the right contractor in Ottawa lists the exact questions to ask.
6. Lock the schedule before demolition
Long-lead items set the real start date — kitchen cabinets alone often take 4–10 weeks from order. Agree on a written timeline, delivery dates, and how changes will be priced before the first wall opens.

What makes planning different in older Ottawa homes?
Ottawa's housing stock skews old — and homes built before 1990 routinely contain asbestos in vermiculite attic insulation, pipe wrap, vinyl floor tile, and drywall compound. Disturbing those materials without testing isn't just risky; it's illegal under Ontario Regulation 278/05. Because HMJ Contracting is licensed for both renovations and asbestos abatement, a positive test doesn't mean stopping the project to find a second contractor — the same company removes the hazard and carries the renovation through.
Common questions about renovation planning
How do I plan a residential renovation in Ottawa?
Plan a residential renovation in six steps: define the scope in writing, set a budget with a 10–20% contingency, test for hazardous materials if the home is pre-1990, confirm whether a City of Ottawa building permit is needed, hire a licensed and insured contractor with a written quote, and agree on a schedule before demolition starts. HMJ Contracting handles all six steps under one roof, including permits and abatement.
How much should I budget for a home renovation in Ottawa?
Typical Ottawa ranges: bathrooms $15,000–$35,000, kitchens $25,000–$75,000, basement finishing $35,000–$75,000, and whole-home renovations $100–$250 per square foot. On top of the quote, keep a contingency of 10–20% for surprises behind the walls — especially in homes built before 1990.
Do I need a permit to renovate my house in Ottawa?
Cosmetic work — paint, flooring, or new cabinets in the same layout — does not need a permit. Structural changes, moved plumbing, basement developments, and most additions require a City of Ottawa building permit. The City's review period for a complete residential application is typically 10–15 business days, so build it into your schedule.
How long does a residential renovation take?
Bathroom renovations typically take 2–4 weeks, kitchens 4–8 weeks, and basement developments 6–10 weeks including inspections. Cabinet lead times of 4–10 weeks often set a kitchen's start date, so order early. Whole-home projects are scheduled in phases with a written timeline.
What should I check before renovating an older Ottawa home?
If the home was built before 1990, have suspect materials lab-tested for asbestos before any demolition — testing costs about $300–$600 and is legally required before disturbing asbestos-containing materials under Ontario Regulation 278/05. Also budget for possible knob-and-tube wiring or galvanized plumbing upgrades, which inspectors and insurers often flag.
Can I live in my home during a renovation?
Usually yes. A professional crew seals the work zone with dust barriers, protects floors along access routes, and schedules water or power interruptions in advance. For large whole-home projects, phased scheduling keeps part of the house livable while work proceeds elsewhere.
