What are my obligations as a landlord for a basement apartment in Ontario?

As a landlord renting a basement apartment in Ontario, you have extensive legal obligations under the Residential Tenancies Act (RTA), Ontario Building Code, and municipal bylaws - failure to meet these can result in serious liability issues and potential tenant compensation claims.

Your primary obligations fall into several critical categories. Safety and habitability requirements are non-negotiable - your basement unit must have proper egress windows for emergency escape, adequate ceiling height (minimum 6'5" in most areas), proper ventilation, and functioning smoke and carbon monoxide detectors. The unit must also meet fire separation requirements, typically a 45-minute fire rating between your basement apartment and any upper residential areas.

Building code compliance is mandatory regardless of when the unit was created. In Ottawa, this means ensuring your basement apartment meets current zoning requirements (typically R4 zones allow secondary suites), has the required minimum square footage (28m² for bachelor, 37m² for one-bedroom), and includes proper electrical systems inspected by the Electrical Safety Authority (ESA). If your unit wasn't properly permitted initially, you're still responsible for bringing it up to code - "grandfathering" doesn't apply to safety violations.

Maintenance obligations under the RTA are comprehensive. You must maintain the unit in good repair, respond to maintenance requests promptly, ensure heating systems maintain at least 20°C during heating season, and address any water infiltration or moisture issues immediately. Basement apartments are particularly susceptible to humidity and water problems, so you'll need proper dehumidification and waterproofing systems.

In Ottawa specifically, you must comply with property standards bylaws, ensure proper waste collection arrangements, and maintain any required parking spaces. The city can inspect rental properties and issue orders for violations. You're also required to register your rental unit with the city if it's a secondary suite.

Financial obligations include providing proper receipts for rent payments, following strict rules about rent increases (currently capped annually), and returning last month's rent deposit with interest when tenancy ends. You cannot charge key deposits, cleaning fees, or most other additional charges.

Tenant rights protection means you cannot enter without proper notice (24 hours for most situations), cannot discriminate in tenant selection, and must follow proper legal procedures for any eviction attempts. The RTA heavily favors tenants, so documentation of all interactions and maintenance is crucial.
