Five things to confirm with any firm, on this list or not, before you sign. The rules below are Ontario's and Oakville's.
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.
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.
Building permits for homes in Oakville come from the Town of Oakville, and a new house needs one before construction starts. Agree in writing who applies for the permit and books the inspections.
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.
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.
The 10 firms on this list fall into 4 groups, read from what each firm's own site says it does and how it is listed on Google.
Home builders build new houses as their main work, and some take on additions and major renovations too.
Design-build firms design the project and build it under one contract, so one firm answers for the drawings and the work.
Renovation companies renovate existing homes, one room at a time or all of it at once.
General contractors run building projects of many kinds and bring in the trades each job needs.
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.
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.
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.
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.
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.
Building permits for homes in Oakville come from the Town of Oakville. 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.
Every stage of a custom home build in order, with the months each takes, the permits and inspections that gate it, how the builder is paid and the warranty rules in Ontario, BC and Alberta.
