How Ontario Handles Rental Property Rules: A Practical Guide
Ontario maintains 118 local ordinances across all categories, and 3 of those deal specifically with rental property rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Ontario falls on the strict-to-permissive spectrum compared to other cities.
Rental Registration
Ontario does not maintain a citywide rental registry, but landlords must obtain a business license for rental activity under OMC Title 4 and comply with state rent cap disclosure rules.
Key details: Local registry: None in Ontario. Business license: Required under OMC Title 4. AB 1482 notice: Required in all leases. Habitability: Health and Safety Code 17920.3. Contact: Ontario Finance (909) 395-2022.

Ontario is more permissive than most cities when it comes to rental registration. That said, there are still limits.
Just Cause Eviction
Ontario follows California AB 1482 (Civil Code 1946.2), requiring landlords to provide just cause to terminate tenancy after 12 months of occupancy, with relocation assistance for no-fault evictions.

Key details: Local rent control: None in Ontario. State cap: 5% + CPI, max 10%. Just cause: After 12 months. Exempt: Units under 15 years old.

The Bottom Line
Ontario's rental property rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Ontario is broadly strict or permissive.
