San Marcos City App empowers residents and visitors to support the City in its efforts to keep San Marcos safe and clean. It is your gateway to submit service requests to city staff. You can use the app to notify us of things like:

  • Traffic light outages
  • Graffiti
  • Debris
  • Maintenance needs at city-managed spaces (parks, trails, etc.)
  • Stormwater

San Marcos City App creates an efficiency of service for both residents and city staff to report non-emergency concerns through:

Location specific
Based on your phone’s GPS location, you can quickly notify us of where you observe an issue when you submit a request.

Progress tracking
You can track the progress and resolution of your submitted requests in the app. Other nearby requests will also be viewable, so you can tell if someone else has noticed the same concern.

Direct access
The app connects directly to San Marcos city staff who can help. Submitting service requests through the app is the quickest and most efficient way to get things resolved.

For more details, check out the San Marcos City App Resource Guide.
