Mississauga's ePlans portal is faster than most homeowners expect — when you submit the right drawings on the first pass. Here are the timelines we see in practice across kitchen, bathroom, and deck reviews, plus what to do if the city flags your submission for rework.
Kitchen renovation permit — 10-14 business days
A straightforward kitchen reno (no wall moves, no structural changes) usually clears review in 8-10 business days. Add 2-3 days if you're relocating plumbing fixtures or adding a 240V circuit for an induction range.
The single biggest delay we see: drawings that don't show electrical layout. Mississauga wants every new circuit identified — outlet locations, dedicated circuits for dishwashers and microwaves, GFCI within 1.5m of sinks. Hand-drawn napkin sketches get bounced. Professional drawings done properly get reviewed in 10 days.
If the kitchen involves removing a load-bearing wall, the review jumps to 4-6 weeks — because the city engages a structural reviewer in addition to the building examiner.
Bathroom renovation permit — 7-10 business days
Bathrooms are usually the fastest permit type because most don't change the footprint. A like-for-like bathroom remodel often gets approved within a week.
What stretches it: - Tub-to-walk-in-shower conversions — these require a drain relocation and pressure-test verification, which adds 2-3 days - Adding a fan where there wasn't one before — needs ventilation calcs showing the new fan meets OBC 9.32 air-change rates - New ensuite added to a previously-unbathed bedroom — counts as a new bathroom, needs full plumbing permit + ESA permit + ventilation calcs. Review jumps to 3 weeks.
Our bathroom renovation pages cover specific scopes for Port Credit, Streetsville, and Lorne Park older homes — they almost always need supplemental plumbing notes because of the original galvanized supply lines.
Deck permit — 10-15 business days
Any Mississauga deck over 24" off grade needs a permit. The review checks: - Footing depth (4 ft minimum below frost line) - Joist spacing per the loading table - Ledger flashing detail at the house attachment - Railing height and baluster spacing - Lot setback compliance (typically 6 ft from rear property line, 3 ft from side)
The most common rejection: ledger attachment showing screws into siding instead of bolted through the rim joist with proper flashing. We submit a detailed cross-section showing the flashing membrane behind the ledger board so this doesn't come back.
What to do if your permit gets bounced
Mississauga will email an "items to be addressed" list. Most rework requests fall into three buckets:
1. Missing details on drawings — usually structural notes, electrical layout, or ventilation specs. Fastest fix: get the drawings done properly the first time 2. Setback violations — your property line might not be where you think. Pull the property survey before designing 3. Building Code interpretation — sometimes a reviewer flags something correctly built per OBC. A 1-page response letter citing the code section usually resolves it within 2-3 days
Resubmissions get pushed to the back of the queue and add 5-7 business days. Average homeowner who tries to draw their own permit submission adds 3 weeks to their timeline.
The fastest-permit shortcut
We submit drawings in DWG + PDF on the first pass with full code references. Our Mississauga reno permits typically clear in the FAST track time bands above because reviewers know what they're looking at.
For your specific project, the quote calculator below gives a real range — we include permits + drawings as part of every scope, not a surprise extra.
