Why Plumbing Is a Non-Negotiable for Landlords
Whether you’re a seasoned property investor or managing your first rental unit, maintaining the plumbing system isn’t just about fixing leaky faucets—it’s about protecting your investment, avoiding tenant complaints, and staying compliant with rental housing laws in Ontario.

This guide provides a structured, actionable plumbing maintenance roadmap tailored for landlords—optimized for performance, compliance, and long-term property health.

24–48 hours is typically the window within which repairs must be initiated after tenant notice.
