Project-specific requirements

After you speak with your team, they will explain what’s needed for your project.

Sprinkler drawings

Sprinkler drawings are not needed at the time of application, but they must be submitted for approval after permit issuance and prior to installation.

Alterations, renovations and additions

Your drawings must differentiate between the existing building and the proposed new work. After you speak with your team, they will explain what’s needed for your project.

Processing time

When we get your application, we will review it within:

• 10 business days: renovation or new construction of a house where no dwelling unit is above another dwelling unit, a detached structure that serves a house and does not exceed 55 m² in building area and tents.
• 15 business days: renovation or new construction of a building smaller than 600m² or three storeys
• 20 business days: buildings larger than 600m²
• 30 business days: post-disaster buildings and building classified as a high building

We appreciate your patience if processing times are longer than the times listed above.

When the review is complete, staff will email you to inform you that the permit is ready for issuance or a status letter with a list of deficiencies that you will need to address in order for the permit to be issued.

Timeframes for re-reviews will vary depending on permit application activity levels.
