Whitby Building Permit FAQs
Do I need a building permit in Whitby?
The Town of Whitby requires a permit for most structural and layout work — additions, second storeys, basement apartments, decks above a set height, garages, removing or altering load-bearing walls, and new openings. Replacing finishes generally does not need one. Send us your scope and we will confirm what Whitby will require at no charge.
What drawings does the Town of Whitby ask for?
A Whitby submission usually needs a site plan, existing and proposed floor plans, elevations, sections, and structural details for beams, lintels, framing and foundations. Depending on scope, the Town may also request grading information, energy efficiency compliance or a survey. We build the package to the Town of Whitby checklist rather than a generic one.
How do I check my Whitby building permit status?
The Town of Whitby operates an online portal where applications and inspection requests are tracked. If your application is showing comments or a hold, send them to us — we interpret the plan examiner’s notes, revise the drawings and resubmit on your behalf.
Does Whitby have its own engineering and standard drawings?
Yes. The Town of Whitby publishes engineering standards and standard drawings that apply to servicing, grading and site works. We design to those standards where your project touches them, which avoids the most common cause of a resubmission on Whitby applications.
Do you handle Whitby building inspections?
We carry out structural inspections and issue engineer letters for properties in Whitby — foundation and settlement reviews, pre-purchase structural opinions, and assessments requested by the Town in response to a work order. These are separate from the Town’s own permit inspections.
Can you prepare drawings for a basement apartment in Whitby?
Yes. Whitby permits additional residential units subject to zoning, and the Building Code requirements for fire separation, sound, egress windows, ceiling height and ventilation still apply. We confirm the local by-law position first, then design the unit around what is actually permitted on your property.
What if work was already done in Whitby without a permit?
It is a common situation and it is resolvable. We assess what was built, prepare drawings documenting the as-built condition, and identify any remedial work needed for a retroactive permit with the Town. Send us photos and we will explain the realistic path.
How do I get a quote for Whitby permit drawings?
Call us or send the quote form on this page with your Whitby address, a description of the work, and any sketches, surveys or existing drawings you have. We review it and reply with a free, no-obligation quote. There is no charge for the initial review.
