Contracted Security

CHOA has a contract with a private security firm that conducts nightly patrols through the Common Areas. This vendor is not responsible for patrolling the private streets or individual residences; they patrol facilities like the Clubhouse, pools, and tennis courts after-hours.

Residents may contact security to report an issue on the Common Areas, such as individuals in the pools after hours, or congregating in the greenbelt or facilities past 10pm. However, the police department can also respond to issues like this as it is trespassing, and will likely be able to send someone out quicker than the security company.

To contact security, residents may call 925-455-6585

As a reminder, please know that CHOA residents are highly encouraged to call the police if wanting to report suspicious activity anywhere on site. The police are equipped to remove trespassers from CHOA property, and will likely be able to respond more quickly to a serious concern. Residents should call security to report concerns that are not serious or time-sensitive in nature. Please note that this security vendor, much like the previous vendor, may only respond to owner calls during the nighttime and early morning patrol hours.
