A one-alarm fire has caused damage to a management office in an Oakland parking garage.

Two fire units responded to a call at the Meyran Avenue garage at 2:35 p.m. Tuesday after a security guard on duty noticed the blaze. Fire crews from the Pittsburgh Fire Bureau Station number 14 were able to contain the fire to the level two office.

No one was injured and it is unclear what started the fire, according to a security guard on the scene. The fire did not interfere with the garage’s operation.

The garage, which is located on the 200 block of Meyran Avenue, showed damage on an outer wall on the side facing Semple Street. Inside the structure, unidentifiable burnt remains and an incinerated desk chair sat outside the office.

Inside the level two office, the fire burned away the insulation on the walls, destroyed all furniture inside and broke the window, which faced Semple Street.

On the first level, another office directly below the burned one was partially flooded with water from the fire hoses. The lower office served as storage for road salt.

A Pittsburgh Parking Authority employee who was on the scene shortly after fire crews had put the fire out declined to comment on the blaze. A representative from the Authority could not be reached by phone Tuesday evening.

Shortly after 5 p.m., Dave Melani from Fire Water Response 365, a company that assesses and fixes fire, water and smoke damage, arrived at the garage to assess the damage. Melani declined to give an estimate on the damage.
