March Luncheon

Program: Palace Hotel Retrofit and Renovation Ukiah, CA

The Palace Hotel is a 127-year-old structure with a significant history and relevance on Main Street in downtown Ukiah.  It was added to the National Register of Historic Places, California in 1979.  The Building was constructed in three phases consisting of a 1891 unreinforced brick masonry (URM), 1914 URM, and the final phase a 1929 reinforced concrete frame building.  The building has been mostly vacant and in significant disrepair and in danger of collapse for many years.  With pressure and litigation from the City as well as swelling public support, the building will experience a much-needed seismic upgrade and structural restoration en-route to being reborn into a potential boutique hotel and shining star in the community once again.  ZFA will present a brief history of the building and key aspects of the scope, retrofit scheme, and challenges including saving the infamous bar!
