How it comes to light
Enforcement is usually complaint driven. A neighbour objects to parking or noise, a tenant complains about a safety issue, or an unrelated permit application puts an inspector in the house. It can also surface at the least convenient moment: when you go to sell, when your buyer's lender orders an appraisal, or when you make an insurance claim.
The awkward truth is that an unpermitted suite can sit quietly for years and then become a problem in a week, for reasons entirely outside your control.
What can follow
- An order to comply — bring the suite up to the required standard through the proper permit process, or remove the elements that make it a suite.
- Retroactive permitting, which means opening finished walls so the work behind them can actually be inspected. That is where the cost lives.
- Removal if compliance is not achievable on the property — sometimes zoning simply does not allow a suite there, and no amount of money fixes that.
- Collateral damage — an insurer taking a position on coverage, a lender taking a position on the income, and a tenant who has to be housed somewhere.
By the time it is your title, it is your problem. The seller who built it is not the person the order is addressed to.
Before you buy, not after
Check the City's secondary suite registry and confirm the property's status with the City directly. A listing that says legal suite is a marketing claim, not evidence — and neither is a second kitchen, a separate entrance or a seller who says it was done properly. If suite income is part of how you afford the house, verify it in your condition period.
