Environmental Protection Maryland 3 Minutes Read · published February 08, 2026 Flag of Maryland

Baltimore, Maryland property owners must follow city rules for connecting private plumbing to the municipal sewer system. This guide explains who enforces connection standards, how to apply for permits, typical documentation, enforcement pathways and practical action steps to complete or regularize a connection in Baltimore.

Overview

Connections between buildings and the public sewer (side sewers/private laterals) are regulated by the City Department of Public Works and city code provisions. Work on side sewers generally requires a permit, inspection and compliance with construction standards; some work may trigger additional review for stormwater or combined-sewer considerations. For official requirements and application instructions, consult the Department of Public Works - Side Sewers page Department of Public Works - Side Sewers[1].

Always confirm permit types and submittal steps with DPW before starting excavation or connection work.

Penalties & Enforcement

Enforcement authority: the Baltimore City Department of Public Works (DPW) enforces sewer connection standards, inspects work, and issues orders where violations occur. Specific enforcement procedures are set by DPW and by applicable city code provisions referenced by the department.[1]

  • Fine amounts: not specified on the cited page.
  • Escalation (first/repeat/continuing offences): not specified on the cited page.
  • Non-monetary sanctions: orders to correct, stop-work orders, disconnection or physical remediation may be imposed; specific remedies and procedures are not specified on the cited page.
  • Inspection and complaint pathways: report illegal or dangerous connections to DPW or 311; DPW schedules inspections and issues compliance notices.[1]
  • Appeals and review: the cited DPW page does not specify administrative appeal time limits; appeal routes and deadlines are not specified on the cited page.
If you receive a notice from DPW, act quickly to request inspections or permitting details to avoid escalation.
