What to check before hiring a custom home builder in Kitchener

Five things to confirm with any firm, on this list or not, before you sign. The rules below are Ontario's and Kitchener's.

  1. Registration with the WSIB

    Ask the firm for a clearance certificate from the WSIB, which confirms it is registered for workers' compensation and its account is in good standing. The certificate confirms the firm is registered with the WSIB and up to date on its premiums, so check its dates cover your job.

  2. Liability insurance

    Ask for a certificate of insurance that names the firm and shows commercial general liability coverage in force for the dates of your job, and check that the subcontractors it brings in are covered too.

  3. The building permit from Kitchener

    Building permits for homes in Kitchener come from the City of Kitchener, and a new house needs one before construction starts. Agree in writing who applies for the permit and books the inspections.

  4. A written contract

    Get the scope of work, the payment schedule tied to stages of the work, start and finish dates, how changes are agreed and priced, and who handles permits and cleanup, all in one signed contract before any work starts.

  5. The new home warranty

    A new house in Ontario must be built by a builder licensed by the Home Construction Regulatory Authority (HCRA) and comes with Tarion's warranty: one year on workmanship and materials, two years on items such as water penetration and the electrical, plumbing and heating systems, and seven years on major structural defects.

Custom home builders in Kitchener: common questions

What is the difference between a custom home builder and a production builder?

A custom builder builds one home to your plans, on your lot or a lot you choose together. A production builder sells homes from a set range of plans in its own developments, with a fixed list of options and upgrades.

Does a new home come with a warranty?

In British Columbia, Alberta and Ontario, new homes must carry third-party home warranty coverage, and the builder registers each home before construction starts. Ask the builder which warranty provider covers its homes and what the coverage includes.

Should the builder or an architect design the house?

Either can work. Many custom builders offer design and build under one contract, with a designer or architect on their team. Others build to plans you bring from an independent architect. Ask to see finished homes built from both routes.

What should I ask a custom home builder before signing?

Ask to walk through homes it has finished and to speak with past clients, which warranty provider covers its homes, who will design the house, how changes are handled once building starts, and who applies for the permit and books the inspections.

How do I check that a contractor in Kitchener is registered with WSIB?

Ask the firm for a clearance certificate from the WSIB. The certificate confirms the firm is registered with the WSIB and up to date on its premiums, so check its dates cover your job.

Who issues building permits in Kitchener?

Building permits for homes in Kitchener come from the City of Kitchener. For custom home building, a new house needs one before construction starts. Many firms apply for the permit as part of the job, so agree who does it before you sign.
