The permit and inspection process is one connected workflow: you apply for a permit before work starts, the building department reviews it against the code, you build in stages, an inspector signs off each stage before you cover it up, and the building is cleared for use only after the final inspection or an occupancy approval. The same shape applies across Canada because the permit is always issued and inspected by the authority having jurisdiction (AHJ), which is almost always the municipality. The details (fees, exact stages, which forms) are set locally, but the lifecycle is the same wherever you work.
The lifecycle, start to finish
Think of it as five phases that run in order:
- Decide whether you need a permit. Structural work, additions, decks above the height your municipality sets, finishing a basement or adding a suite, plumbing changes behind walls, major electrical, HVAC installation, and demolition almost always need one. Painting, flooring and like-for-like fixture swaps usually do not.
- Apply and pay. Submit drawings or plans, a site plan, a description of the work, and proof of any licence or insurance. The fee is set by each municipality and varies a great deal, so confirm the current local figure rather than assuming a number.
- Plan review. The building department checks the application against the building code and the zoning rules, and either issues the permit or asks for changes.
- Build in stages, inspected as you go. You book each inspection at the point the permit specifies. Each stage must pass before you close it in.
- Final sign-off and occupancy. The building is legally usable only after the final inspection passes, and larger projects may need a separate occupancy approval.
The detail of phases 1 to 3 is in Getting a Building Permit. This guide is about how the pieces fit together as one process.
How permits and inspections connect
The permit is not just a piece of paper at the start. It defines which inspections you must book and when. When the permit is issued, it sets out the hold points: the stages where work must stop until an inspector approves it. Skipping a hold point breaks the chain, because the next inspection assumes the previous one passed.
The cardinal rule of the whole process: never close in work that still needs inspection. If drywall goes up before the framing, plumbing rough-in or electrical rough-in is signed off, the inspector can order it reopened at your cost (the inspection detail is in Inspections and Occupancy).
The typical inspection sequence
For a typical residential job the order runs:
- Footing and foundation, before concrete is poured.
- Framing, once the structure is up but still open.
- Plumbing rough-in, before lines are concealed.
- Electrical rough-in, inspected by the provincial electrical safety authority, not always the municipal inspector.
- HVAC rough-in, before ducts and gas lines are covered.
- Insulation and vapour barrier, before drywall.
- Final, the completed job.
Electrical is the common exception to the "one inspector" assumption. In most provinces electrical work is permitted and inspected separately by the electrical safety authority, so you book that inspection through them, not the building department (see Pulling an Electrical Permit).
Where the process differs by province
The lifecycle holds nationwide, but two things shift with jurisdiction:
- Quebec. The municipality issues the building permit and is required to notify the RBQ of permits it grants. The RBQ itself does not issue building permits; its role is contractor licensing and the Construction Code. So in Quebec you still apply to the municipality, but you must also hold the right RBQ contractor licence to do the work commercially (see Contractor Licensing by Province).
- Specialised permits sit outside the building permit. Electrical and, in many provinces, gas are permitted by their own safety authorities. You can hold a valid building permit and still be missing the electrical or gas permit you need.
Occupancy: the last gate
Occupancy is the point at which a building is legally allowed to be lived in or used. For most small residential jobs, passing the final inspection clears the building. Larger or more complex projects may need a formal occupancy permit before anyone moves in, and some allow conditional or partial occupancy while minor items are finished. Moving in before occupancy is granted can breach the permit and void parts of home insurance, so confirm with the building department exactly what sign-off is needed.
Common mistakes
- Starting before the permit is issued. Working ahead of approval risks a stop-work order and can force you to uncover finished work.
- Booking inspections too late, or not at all. The permit sets hold points. Miss one and the inspector can make you open the work back up.
- Assuming the building department covers electrical. Electrical (and often gas) is inspected by a separate safety authority. Book it through them.
- Occupying before sign-off. Using the building before the final inspection or occupancy approval can breach the permit and affect insurance.
