Choosing a custom home builder in Burlington involves more than comparing photographs and prices. Before signing, you need to understand who will manage the work, what the proposal includes and how the builder handles decisions, changes and follow-up.
A portfolio helps you assess the finished product. A builder’s credentials, references and written proposal help you understand the business relationship behind it.
Start with a shortlist of builders whose experience fits your project. Then ask each one the same questions. The goal is not to find someone who gives a polished answer to everything—it is to find a team that explains its responsibilities clearly and supports its answers with evidence.
Start With the Builder’s Credentials
Before investing significant time in design conversations, check the company in the Ontario Builder Directory, operated by the Home Construction Regulatory Authority, or HCRA.
Match the company’s legal name and licence details to the entity that would appear on your contract. Review the available history and any conditions or regulatory actions, and ask for clarification where needed.
HCRA licensing and Tarion enrolment serve different purposes. HCRA licenses new-home builders and vendors; Tarion administers the statutory new-home warranty framework and provides project-specific authorizations.
For a contract home built on land you own, Tarion states that the contract-home builder must hold both vendor and builder licences. It also distinguishes authorization to enter into the transaction from enrolment confirmation required before construction begins. Tarion’s application guidance explains these requirements.
These checks are an essential starting point, not a guarantee of workmanship or a good working relationship. The following questions help you evaluate the rest.
1. What Is Your Legal Company Name and HCRA Licence Number?
Ask which entity will sign the contract and whether it holds the licences appropriate to your project.
A trading name on a truck or website may differ from the legal company name. That difference is not necessarily a problem, but it should be explained clearly.
What to look for: Current licence details that match the proposed contracting entity, with an explanation of any relevant conditions or differences in names.
Do not rely solely on familiar phrases such as “Tarion registered.” Check the current records rather than judging the builder’s terminology alone.
2. How Will Tarion Enrolment and Warranty Coverage Be Addressed?
Ask what authorizations are required for your home, when they will be obtained and what documentation you will receive.
For applicable new-home construction, Tarion enrolment confirmation is required before excavation begins. However, enrolment is not the only consideration when determining warranty eligibility.
This is particularly important if you intend to hire trades directly, supply significant portions of the work or use a construction-management arrangement. Those choices can affect whether the home is treated as a contract home or an owner-built home. Confirm the implications with HCRA and Tarion before committing. HCRA’s builder advisory explains why the contract and actual control of construction both matter.
What to look for: A clear explanation of the applicable coverage, required confirmations and responsibilities—not simply a verbal assurance that everything is covered.
3. What Insurance and Workplace Coverage Apply?
Ask for evidence of commercial liability insurance and an explanation of the workplace coverage and clearance requirements that apply to the project.
Confirm who is responsible for construction-related property insurance as well. Do not assume the builder’s liability policy replaces insurance you may need as the property owner.
What to look for: Current documentation identifying the insured company, coverage period and relevant limits, plus applicable WSIB information.
If something is unclear, have your insurance adviser review it. Documents should be current when work begins, not just when you first meet.
4. Have You Completed Similar Homes, and Can I Speak With Those Clients?
Look for relevant experience beyond architectural style.
A builder may have an appealing portfolio but limited experience with your project’s size, structural complexity or site constraints. Ask what role the company played in each example and who provided the design.
Request references from comparable projects, including clients who have lived in their homes long enough to discuss follow-up service.
Useful questions for those clients include:
- Did the written scope reflect what was delivered?
- How were unexpected costs and delays explained?
- Was communication consistent?
- How were outstanding items handled after completion?
What to look for: Relevant project examples and references provided with the clients’ permission. Respect privacy; an occupied home may not be available for a tour.
5. Who Will Manage My Project Day to Day?
The person presenting the proposal may not be the person supervising construction.
Ask who manages the site, who coordinates schedules and selections, and who will be your main contact. Clarify which roles are in-house and which are provided by subcontractors or consultants.
It is also reasonable to ask about the team’s anticipated workload and how your project will be staffed.
What to look for: Defined responsibilities, a proposed communication routine and an explanation of who provides coverage when your usual contact is unavailable.
A sample progress update can reveal more about communication than a promise to “keep you informed.”
6. Who Prepares the Drawings, and How Can I Verify Their Qualifications?
Ask who is responsible for architectural design, structural engineering and permit documentation.
The appropriate credentials depend on the professional and scope of work. A registered building designer’s qualifications may be checked through Ontario’s QuARTS system, while architects and engineers have separate professional licensing arrangements.
A BCIN is an identification number; the relevant qualifications and registration still need to be checked.
What to look for: Named professionals, appropriate credentials and a clear division of design responsibilities.

7. How Is the Price Established, and What Does It Include?
Ask whether the proposal uses a fixed price, cost-plus arrangement or another pricing model. Then look beyond the headline amount.
A useful scope identifies what is included, excluded, assumed or covered by an allowance. Ask how site work, servicing, appliances, landscaping, professional fees and taxes are addressed rather than assuming they are included.
Allowances deserve particular attention. A proposal with low finish allowances may appear less expensive without reflecting the selections you intend to make.
What to look for: A written scope and pricing breakdown that let you compare proposals on equivalent terms.
If two prices differ substantially, ask each builder to explain the difference before deciding that one offers better value.
8. How Are Changes Priced and Approved?
Changes may arise from your requests, unavailable products or conditions discovered during construction.
Ask how the builder documents the reason for a change, its cost and its effect on the schedule. Clarify who can authorize it and how urgent situations are handled.
What to look for: A sample change-order form and a written approval process.
Avoid relying on informal conversations as the record of an agreed change. A quick request during a site visit can affect several trades or materials already ordered.
9. How Do Payments, Deposits and Holdback Work?
Ask what triggers each payment and how the amount relates to work completed, materials purchased or other documented commitments.
Deposits and procurement payments may form part of the agreement. Their purpose, timing and treatment should be clear.
Ontario’s Construction Act includes statutory holdback requirements and release procedures. These obligations are more involved than simply showing a deduction on an invoice. Have an Ontario construction lawyer review the proposed payment and holdback arrangements before signing. The Construction Act is the authoritative reference.
What to look for: A written payment schedule, clear invoicing and contract terms that explain how applicable holdback obligations will be managed.
10. Who Handles Permits and Other Approvals?
Ask who determines which approvals are needed, prepares submissions, responds to comments and arranges required inspections.
For a Burlington custom home, the approval path can involve more than the building permit itself. Property-specific requirements may affect zoning, grading, servicing or other aspects of the proposal.
Clarify what the builder’s fee includes and which documents or authorizations you must provide.
What to look for: Assigned responsibilities and a realistic explanation of outstanding approvals—not a promise that every property follows the same timeline.
11. What Schedule Is Realistic for This Project?
Separate design and approvals from the construction period.
Ask which dates are preliminary, what assumptions support them and what needs to happen before a start date can be confirmed. Discuss material lead times, site conditions, homeowner selections and other factors that could affect progress.
What to look for: A schedule organized by meaningful milestones, plus a process for communicating changes.

12. What Happens at Handover and After I Move In?
Ask how the final walkthrough, applicable pre-delivery inspection, system demonstrations and outstanding-item list will be handled.
You should also understand how to report a concern after moving in and who coordinates follow-up.
What to look for: A documented handover process, warranty information, maintenance guidance and a clear contact for service.
A well-finished home matters. So does knowing how the builder responds when something needs attention later.
How to Compare the Answers
After each meeting, record what you were told and which documents remain outstanding.
Use the same headings for every builder: credentials, relevant experience, team, scope, pricing, schedule, communication and follow-up. This helps prevent a compelling presentation or one attractive price from dominating the decision.
Read online reviews for recurring themes, especially around communication and problem-solving. Consider them alongside references and regulatory records rather than treating any one source as a complete assessment.
Assess concerns by their seriousness, not by counting warning signs. A minor administrative delay is different from refusing to identify the contracting company or provide a written scope.
If an answer remains unclear after a reasonable follow-up, note that uncertainty before making a commitment.
Frequently Asked Questions
How many custom home builders should I interview?
Two or three well-matched builders can provide a useful comparison without turning the process into an extensive tender exercise. Give each the same project information and explain how developed your plans are.
Should I choose the lowest proposal?
Only after understanding what it includes. Compare scope, specifications, allowances, exclusions and pricing terms. A lower total is not necessarily a lower cost for the same completed home.
Can I hire trades directly to reduce costs?
Discuss this before signing. Directly managing or supplying parts of a new-home build can affect responsibilities, coordination and warranty eligibility. Confirm your proposed arrangement with the relevant authorities and your lawyer rather than assuming coverage remains unchanged.
