The signature offering at a northwest side restaurant is more smoked than honey baked after an early morning fire Tuesday.

Soon after the electrical fire broke out at the Honey Baked Ham & Cafe, 7090 N. Oracle Road, the chain’s corporate website posted a notice that it was “temporarily closed due to water damage.”

The Northwest Fire District was alerted to the blaze at 5:38 a.m., when “an automatic fire alarm activation was received,” Capt. Adam Goldberg, spokesman for the district, said in a news release.

The first engine company arrived within six minutes "to find an audible alarm sounding, flooding from the front door from the automatic sprinkler systems that had been activated and smoke also coming from the entry way,” he said. “A full alarm was requested which brought three additional engine companies, a ladder company and support units to the scene.”

Deputies from the Pima County Sheriff’s Department evacuated several construction workers from a neighboring suite in the complex.

The Honey Baked Ham store was closed at the time and there were no employees in the store at the time of the incident, Goldberg said.

The fire, behind a large refrigerator unit, was kept in check by the sprinkler system and crews extinguished the remaining hot spots. They also opened the attic space and walls to determine whether the fire had spread.

It took 11 minutes to bring the fire under control.

Investigators at the scene determined the cause of the fire was an electrical malfunction related to the refrigerator unit. Damage was estimated at about $20,000.

The store will remain closed while electrical repairs are made, the restaurant is cleaned up and it receives a health inspection, Goldberg said.
