Warren Boulevard on Chicago's Near West Side, facing Union Park. It was designed by architect Benjamin Albert Comm and built in 1929-1930.","why_significant":"The nomination argues the hotel is locally significant under Criterion C for Architecture as a distinctive example of French-influenced Art Deco design. Its colorful glazed terra cotta facade and abundant Art Deco motifs are described as innovative and unusual in Chicago. The facade also reflects the importance of Chicago's terra cotta industry. The building keeps its original form, massing and ornament.","narrative":"Facing Union Park on Chicago's Near West Side, this six-story hotel at 1519-1521 West Warren Boulevard was built in 1929-1930 to designs by architect Benjamin Albert Comm. Its main facade is clad in glazed terra cotta in creamy beige, brown, gold and pastel tones, with sunbursts, zigzags, chevrons, fluted piers and stylized palm fronds. The sides and rear are plain common brick. Inside, the hotel offered a modest lobby with Art Deco plaster and tile details and compact guest rooms for workers of modest means who needed to live near the Loop. The building was listed for its architecture, as a locally significant example of French-influenced Art Deco design and of colorful terra cotta work in Chicago. Later changes include replacement windows and doors and an entrance canopy added after it became the Viceroy Hotel in 1963. The building is now vacant, with plans for rehabilitation as affordable housing.","period_of_significance":"1929","architect_builder":"Benjamin Albert Comm, architect; Arthur A.
