Submission standards

Help us process your application faster by following the document submission standards. These standards allow for easy identification of drawings by naming convention and vector file types for most efficient review.

Organize drawings and documents as separate files. Each document file can contain multiple pages like site plan drawings.
Orient drawings in landscape. Orient forms and documents in portrait.
Save all files in Vector PDF format, unlocked/editable, greyscale, flattened into a single layer and free of comments. Tip: To convert drawings created in AutoCAD to vector PDF, use Autodesk Vector Graphic Converter “DWG to PDF.pc3 plotter”.
Submit searchable PDF files for calculations, reports and other supporting documents (non-drawing files), when possible.
If including scanned documents, resolution of 1-bit black-and-white 300 dpi is usually acceptable. For plans and drawings with fine lines and detail, 600 dpi resolution is required. Full-colour renderings and photos may be submitted, but only as supplements to a sufficient set of plans. Grayscale is preferred.
Naming conventions: Please name your files according to the standardized naming conventions (pdf).
Resubmissions: In the event you are requested to resubmit materials, please provide the documents requested only. Please do not resubmit the entire application package at this time, unless otherwise requested to do so.

Remember to have drawings, schedules and general review forms signed and dated by the appropriate designers. Make sure drawings are ready for review and are free of markings such as “not for construction”, “for reference only” or “preliminary”

Final inspection and release of securities

Final inspections are required prior to releasing site securities and are intended to confirm that work has been carried out in accordance with the approved plan.

Securities are collected prior to issuance of approval.
Upon completion of your project, a request for inspection may be submitted using the online services.
Prior to requesting a final inspection, a final Lot Grading Certification (pdf) is required from the site surveyor to verify they have been on site within the past 30 days of the dated letter, and that the works have been carried out in accordance with the plan. Site photos must be included with submission of the LGC.
Application fees include a maximum of two inspection visits. Additional inspection fees will be charged after the two failed inspections.
