What to check before hiring a custom home builder in St. John's

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

  1. Registration with WorkplaceNL

    Ask the firm for a clearance letter from WorkplaceNL, which confirms it is registered for workers' compensation and its account is in good standing. WorkplaceNL issues clearance through its online service, so a firm in good standing can produce one.

  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 St. John's

    Building permits for homes in St. John's come from the City of St. John's, 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

    Ask whether the house will be enrolled in a third-party new home warranty, such as Atlantic Home Warranty, and what that warranty covers and for how long.

Custom home builders in St. John's: 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 St. John's is registered with WorkplaceNL?

Ask the firm for a clearance letter from WorkplaceNL. WorkplaceNL issues clearance through its online service, so a firm in good standing can produce one.

Who issues building permits in St. John's?

Building permits for homes in St. John's come from the City of St. John's. 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.
