After-Hours Emergencies

In the event that you notice an HOA maintenance emergency outside of Keystone’s regular business hours, please call (949) 833-2600, which will direct you to follow prompts to be connected with a live person, with their contracted emergency service.

The emergency service will request the following information from you:

  1. The name of your Association: Aviara Master Association
  2. Your property address and phone number
  3. The nature of the emergency service needed, in order to dispatch the correct vendor, to assist with the resolution
  4. The address or cross streets of the emergency, if different from your property address

The emergency service will relay all of this information, via text, to Keystone’s “On-Call” Manager. Please keep in mind that the “On-Call” Manager may not be familiar with your property, so please be willing to provide as much detail as possible.
