The building was officially converted to an apartment hotel in 1905. At the time of the conversion, the Chelsea was divided into 125 units. Small studios that had been converted from maids' quarters were available for as little as $1.50 per night (), while units that had one or two bedrooms cost up to $4–5 per night (equivalent to between $ and $ in ). In the first two decades of the 20th century, the hotel hosted events such a merchandise sales; meetings of local groups, like the Chelsea Society of New York and Syracuse University Club of New York; and educational lectures. Following the sinking of the RMS Titanic in 1912, several guests from the Titanic were also given rooms at the hotel. The managers sometimes removed guests' corpses from the hotel. The opening of the New York City Subway's Broadway–Seventh Avenue Line in the late 1910s had spurred development in the surrounding area, although the Hotel Chelsea remained in use as an apartment hotel. One of the ground-level stores was leased to the Greater Engineering Company in 1920.
