If anyone gets out of hand on town-owned property, there’s now a policy for that.

Selectmen recently approved a code of conduct for visitors to town buildings that sets an expectation of civility and gives Rochester Police more authority in instances where town employees feel threatened.

The police suggested the new policy, which is recommended by the Massachusetts Interlocal Insurance Association.

Police Chief Paul Magee said the code of conduct is a “proactive” measure and wasn’t prompted by any untoward behavior, though Magee said sometimes people get heated and emotional, especially when dealing with sensitive matters at Town Hall.

“They can’t come in here and start swearing and screaming. Yes, you can certainly speak your piece, but there are some places where we just have to draw the line,” Magee said.

With the new policy, the expectation is now clearly laid out.

“The thought might be that some people thinks this conduct is OK, but it’s not for other people,” Magee said. “We’re setting some ground rules so that everybody is held to the same standard when they are visiting.”

The expected conduct is listed as follows:

• Avoid causing disturbances or disruptions
• Show respect for others, building facilities and personal property of others
• Use common courtesy when interacting with others
• Do not engage in any lewd or offensive behavior
• Any form of violence is prohibited
• Smoking, drinking alcohol or appearing to be under the influence of any illegal substance is prohibited

Magee said this policy will put everyone on equal footing. It also aims to prevent harassing and violence on town employees.
