The owner of a downtown Mobile property that was engulfed in flames Thursday is expected to turn in a long-term plan next week on how he expects to save the building’s historic facade.

The plan is expected on Wednesday, which would be less than one week after the three-alarm blaze left the vacant building at 407 Dauphin Street badly damaged.

Candace Cooksey, a city spokeswoman, said the property owner is working with the city on the plan that also includes details on how he plans to secure the building. Property records indicate the building is owned by Ronald Hoffman of Atlanta. The Hoffman family has long owned and operated an adjoining furniture store along the 400 block of Dauphin Street.

For now, the city says that efforts are underway to implement a temporary remedy to secure the building and its facade. That work is expected to begin “as soon as possible,” Cooksey said. As a precaution, the city is closing off the sidewalk and on-street parking in front of the building. Barricades will also be put in place until the building can be “secured permanently,” she said, and pedestrians are asked to avoid the area.

Mobile Fire-Rescue is crediting a quick response from firefighters from preventing a blaze that could have destroyed an entire downtown city block.

The agency, in a Facebook post Friday, reported that the response to the blaze around 9:35 p.m. kept it from spreading to the connected buildings on Dauphin Street. The building is less than one block from the Cathedral-Basilica of the Immaculate Conception.

There is no estimate of the damages. No injuries were reported and the fire remains under investigation.
