What counts as illegal dumping

Illegal dumping includes leaving household trash, construction debris, appliances, tires, or hazardous materials on streets, vacant lots, alleys, or other public or private property without permission. If the material presents a hazard or blocks access, report it immediately to the city.

How to report illegal dumping

  • Use the city's online report form or 311 to submit location, photos, and time; include license or vehicle information if available. Report online[1]
  • Preserve photographic evidence and note witnesses, dates, and descriptions for investigators.
  • For hazards or large-scale dumping, call the department listed on the report page during business hours.
Reporting quickly with photos speeds investigation.

Penalties & Enforcement

Enforcement for illegal dumping in Denver is governed by the city code and enforced by city departments that manage public works, environmental health, and code compliance. Specific monetary fines and penalties referenced in the municipal code and enforcement pages are cited below.

Fine amounts and penalty structure are not specified on the cited page in exact dollar amounts for every violation; see the municipal code for listed offences and civil or criminal remedies.[2]

  • Monetary fines: not specified on the cited page in a single consolidated table; amount depends on the ordinance section or charging instrument and may be set per incident or per day.[2]
  • Escalation: enforcement may start with notice and abatement orders, then civil fines or criminal charges for repeat or hazardous dumping; specific escalation ranges are not specified on the cited page.[2]
  • Non-monetary sanctions: city may issue abatement orders, require clean-up, seize items, or pursue court actions to recover cleanup costs.
  • Enforcer: Denver Public Works, Denver Department of Public Health & Environment, and Code Compliance units administer investigations and enforcement; contact details and complaint pathways are available on the department pages.[3]
  • Appeals: appeal routes or administrative review procedures are provided by municipal code or court rules; specific time limits for appeals are not specified on the cited page and may appear in the charging notice or ordinance section cited in enforcement paperwork.[2]
  • Defences/discretion: permits, contractor-authorized disposals, or proof of proper waste handling can be defenses; mitigation and discretion are applied case-by-case.
If you receive a notice, follow the deadline to appeal or comply to avoid higher penalties.

Applications & Forms

The city provides an online illegal-dumping report form and 311 intake for complaints; payment of fines typically uses the municipal court payment portal or instructions on the charging notice. If a specific enforcement form or fee schedule is required, it will be referenced on the enforcement notice or municipal code section cited by the city. If no specific form is published for a permit or variance, the city does not list one on the cited pages.[1]

Action steps: report, document, follow up

  • Document: take clear photos showing location, extent, and any identifying marks.
  • Report: submit via the city's online dumping report or 311; include attachments and witness details.[1]
  • Follow-up: note the case number and monitor the city response; if cleanup is ordered, the notice will state schedule and obligations.
  • Pay or contest: follow instructions on the citation or notice for paying online or filing an appeal or request for administrative hearing as directed in the charging paperwork.
Keep a personal copy of all reports and correspondence until the case is closed.
