Utilities and Infrastructure British Columbia 3 Minutes Read · published February 11, 2026 Flag of British Columbia

In Vancouver, British Columbia, property owners and the city share responsibilities for storm drain maintenance. This guide explains who must maintain storm drains and drainage connections, how the City enforces bylaws, common violations, and the practical steps to report problems or apply for permits in Vancouver, British Columbia.

Who Is Responsible

Responsibility depends on location: homes and private properties are typically responsible for on-site drains and connections to the public system, while the City maintains public gullies, catch basins and main storm sewers. For site-specific rules, contact Engineering Services or By-law Enforcement to confirm obligations. [1]

  • Private property owners must prevent debris, soil and pollutants from entering storm drains.
  • The City maintains public catch basins and main storm sewers but may require property-owner action to fix private connections.
  • Report blocked or damaged public drains to the City using official reporting channels.[2]
Keep gutters, downspouts and yard drains clear to reduce flood risk.

Rules and Legal Basis

Storm drainage and related maintenance are governed by municipal bylaws and Engineering Services standards; specific requirements and technical standards are set out by the City of Vancouver. Where an exact bylaw section or fine amount is required, consult the Engineering or By-law Enforcement pages for the controlling instrument and up-to-date text. [1]

Penalties & Enforcement

The City enforces storm drain and drainage-related bylaws through By-law Enforcement and Engineering Services. Exact fine amounts and escalation details are not specified on the cited City pages; where a numeric fine or fee applies, the City’s enforcement pages or consolidated bylaws provide the statutory amounts. See the contact and report links for how to file complaints and request inspections. [1][2]
