A fire blazed through a maintenance building at the Warner Springs Ranch Resort on Sept. 12, and caused an estimated $100,000 worth of damage.

Shortly before 8 a.m., crews responded to the 2,500-sq. ft. metal-walled structure in the 31600 block of state Route 79, according to Cal Fire.

It took crews about 40 minutes to control the flames, which also blackened a patch of adjacent grassy terrain, fire captain Mike Cornette said.

According to reports, the fire damaged about one-quarter of the large multi-room shed and destroyed some of the golf-course landscaping supplies and equipment it houses.

The cause of the fire, which resulted in no reported injuries, is still under investigation.

The back-country resort – which opened as a vacation attraction in the 1920s on the 2,400-acre former grounds of a cattle ranch that had been in operation since the mid-1800s – went into bankruptcy and closed 11 years ago.

At the time, it comprised a 27,000-square-foot main lodge, 250 guest cottages, a 144-acre golf course, a clubhouse, four tennis courts, equestrian facilities, two restaurants, a spa, campgrounds, three swimming pools, a private airport and meeting facilities.

In 2013, a San Diego-based hotel-management company bought the property and announced plans to thoroughly renovate and reopen the resort to the public. However, despite some partial re-openings, it has mostly remained closed since.
