Mississauga Property Standards By-law: Gutters and Drainage
The Mississauga Property Standards By-law sets minimum maintenance standards for private property. If your eavestroughs leak, your fascia is loose or water collects beside the house, start with the sections on roofs and drainage.
This guide focuses on exterior work. Read the City’s current Property Standards By-law 0654-1998 for the complete rules. The City lists a consolidated document dated February 18, 2026.
Gutters, Soffit and Fascia: What the By-law Covers
Section 10 requires roof components, including gutters and downpipes, to remain secure and serviceable. It also addresses roof weatherproofing and the condition of soffit and fascia. Section 37 requires functioning, leak-free roof drainage, subject to its stated exceptions.
Look for leaking joints, loose sections and damaged trim, and watch where the water goes during rain. A damaged corner or loose section may be repairable without replacing the whole system.
Where Should Downspouts Discharge?
Under section 37(3), a downpipe need not connect to a storm sewer if runoff discharges at least three feet from the building and remains directed within the property without flooding neighbouring land. Section 37(4) includes an exception for roofs designed to avoid runoff damage or nuisance.
Three feet is the condition stated in section 37(3), not a complete drainage design. The City’s property drainage guidance recommends extending downspouts two metres from the foundation and away from neighbouring property. Ground slope, nearby structures and the final destination of the water also matter. Review the City’s property drainage guidance before changing a discharge route. Ask the City about requirements for your specific property.
A Practical Exterior Maintenance Check
- From the ground, look for loose gutters, hanging downspouts and damaged fascia.
- Note where leaks or overflow occur during rain.
- Check whether discharge collects near the house or travels toward a neighbouring property.
- Take photos from a safe position and describe the problem when requesting a quote.
- If you received an order, share the relevant repair requirements with the contractor.
