What to check before hiring a home addition contractor in Burlington

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

    Building permits for homes in Burlington come from the City of Burlington, and every addition needs one, and often a zoning review first. 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 warranty

    A renovation is not a new home, so the new home warranty rules usually do not apply: get the firm's own workmanship warranty in writing, with what it covers and for how long. Renovators in RenoMark, the Canadian Home Builders' Association program, offer a minimum two-year warranty on their work.

Home additions in Burlington: common questions

Do I need a permit for a home addition?

Yes. An addition changes the footprint or height of the house, so it needs a building permit and often a zoning review for setbacks and lot coverage. Plans are usually drawn by a designer or architect before the permit application goes in.

Can I add a second storey to my house?

Often, but the existing foundation and walls have to carry the new load. An engineer checks the structure before design starts, and the contractor builds to those drawings.

What happens before an addition is built?

A survey of the lot, a check of the zoning rules for setbacks, height and lot coverage, drawings by a designer or architect, an engineer's review where the structure is affected, and the building permit. Ask the firm which of these steps it handles and which it expects from your designer.

Can I live in my house while an addition is built?

Often. Most of the work happens outside the existing walls until the new space is joined to the house. Expect noise and dust, and a few days without power or water when the addition is tied in.

How do I check that a contractor in Burlington 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 Burlington?

Building permits for homes in Burlington come from the City of Burlington. For home addition work, every addition needs one, and often a zoning review first. Many firms apply for the permit as part of the job, so agree who does it before you sign.
