Denver 311: How to Access Non-Emergency City Services

Denver's 311 system serves as the unified entry point for residents, businesses, and visitors seeking non-emergency city services across Denver's consolidated city-county government. This page explains what 311 covers, how requests move through the system, the types of issues it handles, and where its authority ends. Understanding the scope of 311 helps users route requests accurately and avoid delays caused by misdirected contacts.

Definition and scope

Denver 311 is an integrated service request and information system operated by the Denver Department of Transportation and Infrastructure (DOTI) and coordinated across city agencies. Its core function is to receive, log, and route non-emergency service requests to the appropriate city department, generating a trackable case number for each submission.

The program operates under Denver's consolidated city-county structure, which means a single call, online form, or mobile app entry can initiate action from agencies that are separate entities in most other jurisdictions — combining municipal and county-level services in one interaction. Denver's home-rule status (Denver Home Rule Charter) grants the city broad authority to design and operate service delivery systems independently of Colorado state mandates governing how other counties handle public requests.

Denver 311 accepts contacts through four primary channels:

Phone — Dialing 3-1-1 within Denver city limits or 720-913-1311 from outside the city
Web portal — The pocketgov.com-powered request portal hosted at denvergov.org
Mobile app — The Denver 311 app (available on iOS and Android) with GPS-assisted location tagging
Online chat — Available during staffing hours through the denvergov.org interface

The system operates 24 hours a day, 7 days a week for phone contacts, with live agent availability Monday through Friday, 7 a.m. to 11 p.m., and weekends 8 a.m. to 8 p.m. (City and County of Denver, 311 Service Center).

How it works

When a request enters the 311 system, a case record is created and assigned a unique reference number. The request is then routed to the responsible agency — for example, pothole reports go to DOTI, graffiti on private property goes to Denver Community Planning and Development, and concerns about animal welfare route to Denver Animal Protection.

The routing logic distinguishes between information requests and service requests. An information request (e.g., asking what day recycling pickup occurs on a given street) is typically resolved by the 311 agent directly using agency data systems. A service request generates a work order sent to field operations staff and carries a target general timeframe defined by the service level agreement (SLA) for that category.

SLA timelines vary by category. Pothole repair on high-traffic arterials carries a different target response than a report of a blocked irrigation ditch in a residential area. Requesters can track the status of open cases through the same channel used to submit — phone, portal, or app — using the assigned case number.

The 311 system is connected to the city's public works operations and parks and recreation governance scheduling systems, enabling field crews to receive digital work orders rather than paper dispatches.

Common scenarios

Denver 311 handles a wide range of service categories. The following structured breakdown covers the most frequently submitted request types:

Street and infrastructure issues — Potholes, failed streetlights, damaged sidewalks, malfunctioning traffic signals, and storm drain blockages route to DOTI field operations.
Waste and recycling — Missed garbage or recycling pickup, bulk item removal scheduling, and complaints about illegal dumping connect to Denver's contracted solid waste services.
Graffiti removal — Requests on city property (signals, utility boxes, parks infrastructure) route to city crews; graffiti on private property routes to the graffiti abatement program under Community Planning and Development.
Animal concerns — Stray animals, noise complaints about pets, and licensing questions go to Denver Animal Protection, a division of Denver Public Health and Environment.
Weeds and overgrowth — Complaints about tall weeds on private property route to Code Enforcement under the Department of Public Health and Environment, which can issue violation notices.
Encampments and human services — Reports involving individuals experiencing homelessness route to the Denver Street Outreach Collaborative rather than law enforcement, consistent with the city's STAR (support resources Assisted Response) model. The Denver Human Services Department coordinates these responses.
Permits and licensing questions — Basic questions about permits and licensing can be initiated through 311, though complex applications require direct engagement with the issuing agency.
Noise complaints (non-emergency) — Daytime and evening noise concerns (outside emergency thresholds) are handled by Environmental Quality Inspectors under Denver Public Health and Environment.

Decision boundaries

311 is explicitly not a substitute for emergency services. Any situation involving an immediate threat to life, active crime, fire, or medical emergency requires a call to 911. The distinction is structural: 311 routes to administrative and maintenance response systems, while 911 dispatches Denver Police Department, Denver Fire Department, or emergency medical services.

A secondary boundary separates 311 from regulatory or adjudicatory processes. Filing a formal complaint about a zoning violation that may require a hearing, submitting an open records request under Colorado's CORA statute, or engaging with the Denver Auditor's Office on a labor standards concern each require direct agency contact — 311 can provide referral information but cannot initiate those processes on a resident's behalf.

311 vs. direct agency contact — key contrast:

Contact Type	Use 311	Contact Agency Directly
Pothole on a Denver street	✓	—
Permit application status	Basic inquiry only	Full application/appeal
CORA records request	Referral only	Open Records Requests
Zoning code complaint	Initial report	Formal enforcement proceeding
Stray animal	✓	—
Police non-emergency report	Referral to 720-913-2000	Denver Police non-emergency line

Scope, coverage, and limitations

Denver 311's authority is bounded by the geographic limits of the City and County of Denver. Service requests for issues in unincorporated Jefferson County, Aurora, Lakewood, Englewood, or other adjacent municipalities are outside its scope — those jurisdictions operate separate service request systems. The Denver Metro Area Governance Relationships page documents how Denver's authority relates to neighboring governments.

State-owned infrastructure within Denver's boundaries — including CDOT-maintained highway lanes, Colorado State Patrol activity, and state-owned buildings — does not fall under Denver 311's routing authority. Such issues should be directed to the relevant Colorado state agency.

Federal facilities, including the Denver Federal Center campus in Lakewood and federal courthouses, are also not covered by Denver 311 regardless of their proximity to city-county limits.
