Most Common Permit Rejections & Fixes

Why Ontario Permit Applications Get Kicked Back (and How to Fix Them Fast)
A permit “rejection” usually is not a personal insult. It is the building department saying, “We can’t approve what we can’t verify.” The good news: most kickbacks are predictable. The even better news: most are fixable without sacrificing your start date. The big three causes are missing site info, drawings that do not match each other, and missing structural or energy documentation. Submit a complete, consistent package and you avoid the majority of delays. Here are the eight most common kickbacks, what the reviewer really means by each, and the clean fix – from 45 years of getting files approved across Simcoe County and Georgian Bay.
Why permits get kicked back
Ontario building departments typically do a “completeness” check before they burn time on technical review. If key pieces are missing – or the drawings contradict each other – your file gets returned with comments. That is not them being picky; that is them refusing to guess. The fix is almost never “a better project.” It is a more complete, more consistent package.
The 8 most common permit kickbacks (and the clean fix)
| Kickback | What they’re really saying | The fix |
|---|---|---|
| 1) No proper site plan | “Show lot lines, setbacks, and where this building actually sits.” | Submit a clear site plan with lot lines, setbacks, footprint, and key dimensions – no “approx.” |
| 2) Zoning doesn’t fit | “This proposal exceeds setbacks, height, or coverage.” | Confirm the zoning envelope early. Redesign or pursue the proper planning relief before permit. |
| 3) Plans don’t match | “Your numbers disagree depending on which page I look at.” | Coordinate: same ceiling heights, window sizes, roof pitch, and dimensions across plan, elevation, and section. |
| 4) Foundation is “generic” | “I can’t approve ‘standard foundation’ on an unknown site.” | Provide a foundation plan plus sections with sizes, frost-protection intent, steps, and key notes. |
| 5) Big spans, no proof | “Where are the beams, posts, lintels, and load-path details?” | Add structural details and engineering where the design goes beyond prescriptive rules. |
| 6) Energy compliance missing or mismatched | “Your drawings and energy forms don’t agree.” | Submit required energy-compliance documentation and make the drawings match (windows, insulation, air-barrier intent). |
| 7) Servicing conflicts (rural) | “House placement leaves no room for septic or well requirements.” | Confirm a servicing concept early. Don’t design the house into the only good septic area. |
| 8) Admin items missing | “Wrong forms, missing signatures, missing fees, missing designer info.” | Follow the municipality checklist exactly and submit a complete, signed package in the required format. |
The cheapest way to avoid a kickback – two options
Do it yourself with the step-by-step PDF, or hand us one coordinated set we pre-check against your town’s standard before you file.
We pre-check your package
Send us where your drawings are at and we run them against the same completeness checklist a building department uses – site plan, zoning, matching sheets, foundation detail, structural proof, energy docs, servicing, admin items. We tell you exactly what would bounce and fix it, or assemble one coordinated set from scratch. Anywhere in Ontario.
- We run your file against the town’s completeness standard
- Every sheet made consistent – one source of truth
- The structural and energy proof in before you submit
- 45 years, 300-plus homes – drawings reviewers don’t bounce

Got a comment letter citing a Code clause?
When a kickback quotes an OBC section you can’t decode, ask our OBC Code Navigator in plain English – the first two questions are free, and you can grab the OBC PDF there too.
The sneaky delay-makers nobody warns you about
Even with “good drawings,” some files stall because another approval or missing proof is hiding in the background. These are the usual suspects:
- Outside-agency clearance: properties near floodplains, wetlands, valleys, or shorelines may need Conservation Authority sign-off before the municipality can finalize the permit.
- Rural servicing details: if your lot uses septic or a well, the house placement and grading must leave room for required setbacks and a workable system.
- Entrance / driveway constraints: some roads have specific entrance requirements. If access is not resolved, the site plan can get stuck.
- “We’ll decide later” structural changes: moving a window bank, deleting a post, or widening a garage door often triggers structural revisions and new details – see your engineer’s role.
- Energy details drifting: if windows or insulation change during design, the energy paperwork has to change too. Mismatches are an easy kickback.
None of these are deal-breakers. They are just reminders that a permit is a coordinated package, not a collection of nice drawings.
The “don’t get stuck in the comment loop” method
When you receive a comment letter, your goal is to resubmit once, not five times. Use this simple workflow:
Make a response list
Copy each comment into a checklist and note exactly which sheet will be revised. One row per comment.
Revise and cloud
Use revision clouds and a revision date so your changes are obvious to the reviewer at a glance.
Chase consistency
If you change something on one sheet, update every place it appears. This is where most resubmissions die.
Resubmit as one coordinated set
One clean package is faster to review than a drip-feed of pages. Send it complete, not in pieces.
Pre-submission checklist (steal this)
Run every line before you hit submit. If your package is complete and consistent, you have already done 80% of the “permit game.”
Drawings & design
- Site plan is clear: lot lines, setbacks, footprint, key dimensions
- Zoning verified: setbacks, height, coverage, accessory buildings
- Plans, elevations, and sections match – no conflicting heights or sizes
- Structure is shown (beams, posts, lintels) and engineered where needed
- Foundation details are specific, not “standard”
Documents & servicing
- Energy-compliance documents included and aligned with drawings
- Rural servicing concept works: septic/well space and setbacks
- Outside-agency clearance handled (e.g. Conservation Authority)
- Admin items complete: forms, signatures, fees, designer info
- One source-of-truth set – no stray old versions
Final reality check
The building department is not your design team. They review what you submit. If your submission forces them to guess, they will not. Build the permit package like you are trying to make the reviewer’s job easy – because, secretly, that makes your job easy too. Most permit kickbacks are preventable paperwork problems, not “bad projects.” Get the site plan right, keep drawings consistent, include the required structural and energy proof, and you move faster. And if you do get comments back, respond once – clearly and completely – so your file does not become a recurring series.

Permit rejections in Ontario: frequently asked questions
Why do building permits get rejected in Ontario?
Almost always for one of three reasons: missing site information, drawings that contradict each other from sheet to sheet, or missing structural and energy documentation. Building departments run a completeness check before technical review, so if a key piece is absent or the numbers do not agree, the file comes back with comments. It is rarely “your project is bad” – it is “I can’t verify this from what you sent.” Submit a complete, consistent package and you avoid the large majority of rejections. The reviewer is refusing to guess, not being difficult.
What is the most common reason a permit application is kicked back?
A weak or missing site plan is the most common, closely followed by drawings that do not match – a ceiling height, window size, or roof pitch that reads differently on the plan than on the elevation or section. Reviewers cannot approve numbers that disagree, so any contradiction is an automatic kickback. The fix is a clear site plan with real dimensions (no “approx”) and one coordinated drawing set where every sheet tells the same story. Most other kickbacks – foundation detail, structural proof, energy docs – are variations on “show me, don’t make me guess.”
What does it mean when my drawings “don’t match”?
It means the same dimension or detail shows up differently in different places – the floor plan says one ceiling height, the section says another; the elevation shows a window the schedule does not list; the roof pitch differs page to page. A reviewer cannot tell which is correct, so the file gets returned. This usually happens when someone changes one sheet without updating the others. The cure is to keep a single source-of-truth set and propagate every change everywhere it appears, then resubmit the whole coordinated package at once rather than a few revised pages.
How do I respond to a building permit comment letter?
Turn it into a checklist. Copy each comment into its own row, note exactly which sheet you will revise to satisfy it, make the change, and use revision clouds with a revision date so it is obvious to the reviewer. The critical step most people miss: if you fix something on one sheet, update every other sheet it touches, because the number-one reason resubmissions get re-kicked is the same issue still appearing elsewhere. Then resubmit as one clean coordinated set. The goal is to resubmit once, not five times – a complete, consistent response is what gets a file closed out.
How long does a permit rejection add to my timeline?
It depends on how fast you turn the comments around and whether your resubmission is actually complete. A clean, one-and-done resubmission might add a week or two; a file that bounces repeatedly because each fix introduces a new inconsistency can add months. The review clock effectively pauses while the file is in your court, so most of the delay is on the applicant’s side. That is why a complete, consistent first submission – or a pre-check before you file – is the cheapest time you will ever buy on a build.
Can I avoid permit rejections entirely?
You cannot guarantee zero comments, but you can eliminate the predictable ones, which are the vast majority. Confirm zoning before you draw, submit a dimensioned site plan, keep one coordinated set so the sheets never disagree, specify the foundation, include structural proof where the design leaves prescriptive limits, align the energy documents with the drawings, sort rural servicing and any outside-agency clearance early, and complete the admin items exactly as the municipality requires. Do that and you have closed off all eight common kickbacks. Pre-checking the package against the town’s completeness standard before filing is the surest way to a clean review.
Does the building department help me fix the problems?
They will tell you what is deficient, but they are not your design team – they review what you submit, they do not draw or correct it for you. The comment letter identifies the issues; resolving them is on you and your designer or engineer. Staff can clarify what a comment means if you ask politely, but expecting them to design the fix is the wrong move and slows everyone down. If you do not want to manage the back-and-forth, that is where having a builder or designer pre-check and assemble the package pays for itself.
Note: general guidance, not a ruling on your project. Completeness checks, required documents, and review practices vary by municipality. Confirm with your building department – or have us pre-check the package and we will confirm it for you.
