Canada-wide residential project research

Research permits and approvals before home work begins

Building permits are only one part of the picture. Use project, provincial and municipal guides to identify the questions, documents and official authorities that may matter for renovations, additions, new construction and other residential work.

A better first question

Not “Do I need a permit?”

Ask which approvals may apply to the complete scope, which authority has jurisdiction, and what must be issued before work starts.

Three ways to research a residential project

By project

What are you planning?

Explore additions, decks, basements, sheds, pools, demolition, new homes, secondary suites, trade permits and more.

By jurisdiction

Which province or territory?

Understand how codes, safety authorities, local governments and separate approvals are organized.

By municipality

Which local authority?

Use city-specific starting points and questions, then continue to the official permit department.

Rules can change

Forms, fees, thresholds, code editions and application methods can be updated. Every guide links to an official starting point and displays a review date.

One project, several approvals

Building, zoning, development, electrical, plumbing, gas, heritage, conservation, road, septic and private-property rules may be administered separately.

No permit does not mean no rules

A building-permit exemption may still leave zoning, safety, contractor, condominium, landlord or other obligations in place.
