Start with your project, not a permit name
Write down exactly what you want to change: the use of a room, the structure, the size of a deck, or the footprint of your home. The City’s residential building resources organize requirements around project types. Start there rather than assuming that a neighbour’s approval applies to your property.
Building permits and development permits
Building and development approvals address different parts of a project. Investigate both with the City: construction and safety-code considerations, as well as land use and the proposed development. Receiving one approval should not be treated as confirmation that every other approval is unnecessary.
Basements, decks, garages and additions
Describe existing and proposed dimensions, the intended use and any structural changes. For a basement, distinguish a room renovation from a proposed secondary suite. For a deck, garage or addition, prepare a site sketch showing the work and property boundaries. Confirm the project-specific drawings and application checklist with the City.
Do not overlook trade work
The City’s trade-permit guidance states that new wiring and extending or altering branch circuits require an electrical permit; replacing fixtures alone does not. Constructing, extending or altering plumbing requires a plumbing permit, with exceptions for specified repairs and fixture replacements. Gas work has separate qualification and eligibility rules. Check the exact scope on the official page.
Applications and inspections
Review the current application checklist, gather drawings and property information, and clarify who will apply: you or your contractor. Confirm required inspections and their timing before work is covered up. Retain approval documents and inspection records with your home files. Fees and processing times are not reproduced here because they can change.
Common mistakes to avoid
Do not rely on informal advice as a final decision. Do not assume cosmetic and structural work are interchangeable, or that a contractor’s quote includes applications and inspections. Put permit responsibility in writing and confirm requirements with the City before starting.
