Understand the site or existing building first
For a new build, investigate access, utility connections and the site assessments needed. For a renovation, establish the existing structure, services and intended use. Have qualified professionals plan work involving structural elements, electrical systems or plumbing.
Give every contractor the same brief
Describe dimensions, the intended result, material requirements, access and timing. Ask which parts need a site visit and which cannot yet be priced.
- Does the scope include protection, preparation, materials, installation, waste removal and cleaning?
- Who coordinates work that another trade must finish first?
- Which amounts are fixed, estimated or charged by time and materials?
- Are applicable taxes, travel, scaffolding and inspections included?
Find suitable trades locally
Look for businesses that carry out the specific work in your area. Ask about comparable completed projects, relevant registration or licensing and insurance. Verify credentials with the responsible local body. Reviews are useful context, but they do not establish competence or cover for your job.
Agree changes before they happen
Keep scope, milestones, payment stages and change procedures in writing. Ask for the price and schedule effect of extra work before approving it. Record work before it is concealed and agree which inspections, certificates and instructions will be provided at handover.
Use your own cost figures
Enter estimates and quotations in the worksheet below. A contingency is your planning assumption, not a guarantee that the budget will be enough. Keep unresolved items visible and assign a date for checking them. An incomplete low quote may cost more once the missing work is added.
Your project cost sheet
Enter your own amounts in CAD. Include each cost once. No rates, tax amounts or market prices are supplied. The reserve applies to all five categories. Land, purchase finance and ongoing household costs are outside this worksheet.

Support and applications
Tax relief and local assistance are different routes
The federal Home Accessibility Tax Credit is non-refundable tax relief for eligible renovations, not a cash grant for an ordinary kitchen or furniture purchase. Eligibility includes a qualifying person and dwelling; portable furniture and household appliances are generally excluded. Provincial or territorial assistance has its own conditions.
Where to apply or ask
For federal tax relief, follow CRA’s Home Accessibility Expenses guidance. Ask your province or territory separately about adaptation programs before commissioning work.
What to prepare
- Evidence that the person and dwelling qualify.
- Contracts, itemised invoices and description of the adaptation.
- Supplier details, work dates, address and proof of payment.
- Keep supporting records; CRA says not to send them with the return unless requested.
When to act
Check eligibility before spending. Keep records and claim qualifying expenses on the relevant tax return. The linked CRA page currently explains tax year 2025; check the guidance for the year you claim.
The responsible body determines the documents required in your case. Send personal evidence through its official channel, not through WOHNALIO.

Look beyond the listing. Prepare your viewing, investigate documents and allow for the costs that come after the purchase price.
