On-campus residents will find themselves looking for alternative entrances into their residence halls this Halloween weekend due to an increase in residential security.

Beginning Friday afternoon, the exterior doors of university-owned residence halls will be re-keyed in order to direct foot traffic through main lobby doors until the Halloween festivities conclude Monday morning, and students living in the buildings will have to use the front doors. Assistant Director of Residential Life Robert Donerson said the lockout was instituted to help enforce the no-guest policy Housing and Residential Services applies to residents during Halloween each year.

“If everyone has to enter through the front doors, we can better monitor the no-guest policy,” he said.

Judicial Affairs Coordinator Joyce Ester said the residence staff would focus on enforcing the no-guest policy that begins Thursday at 5 p.m. and ends Monday at 9 a.m. Out-of-town visitors are the primary concern within the residence halls, she said. Ester said that in order to keep out-of-town visitors away, UCSB students must present a valid UCSB ACCESS card to authorities patrolling the residence hall front door before entering the building.

“Our residents have a lot of respect, but there are outsiders that have no commitment to our campus,” Ester said. “This measure is for outside people coming in, causing problems and being a disruption.”

Donerson said the visibility under this method assists both resident advisers and resident directors in keeping prohibited guests at bay. He also said the entire residence hall staff, UC Police Dept. officers and Community Service Officers will be on duty patrolling the buildings for the entire weekend.

“We cannot figure out which night will cause the most trouble,” Donerson said. “We will have the same amount of security each night.”

Residence Hall Manager Terry Campbell said re-keying the locks is a security measure Residential Life takes every year.

“I’ve been here 33 years and I can’t remember a time when we have not changed the locks,” he said. “In the past, pins were inserted into the keyhole to prevent entry, but now the locks are re-keyed by university locksmiths.”

Campbell said the locksmiths will begin re-keying the doors Thursday afternoon from 1 to 4 p.m., and the front lobby doors will remain open under the same schedule as any weekend.

Brian MacDonald, San Nicolas Residence Hall resident director, said he thinks the lockout will benefit residents.

“Overall, we are trying to help residents have a good time and keep guests out,” he said.

Parking is also restricted this weekend for guests of residents and no guests will be permitted to park in the Francisco Torres lots from Oct. 28 to Nov. 1, Campbell said.
