The city's documentation of the extent of this Landmark designation is a bit unclear with respect to two out of seven original buildings. The Department of Neighborhoods alphabetical listing does not entirely agree with the original landmark designation LPB-49/81.Report on Landmark Designation LPB-49/81, City of Seattle Landmarks Preservation Board, 1981-02-19, accessed 2021-08-31. , City of Seattle Department of Neighborhoods, accessed 2021-08-31; equivalent as of 2022-12-23 is https://www.seattle.gov/neighborhoods/programs-and-services/historic-preservation/landmarks/landmark-list. LPB-49/81 calls this "First Avenue Groups"; the Department of Neighborhoods listing calls it "1st Avenue Groups/Waterfront Center" The following properties are listed in one or the other document: The three buildings constituting the present-day Alexis Hotel: Globe Building, listed in LPB-49/81 as 1001-1011 First Avenue and in the Department of Neighborhoods listing as 1005 1st Ave. Beebe Building, listed in both documents as 1013 First Ave (the Department of Neighborhoods listing gives that as 1013 1st Ave). Hotel Cecil, listed in LPB-49/81 as 1019-1023 First Avenue and in the Department of Neighborhoods listing as 1021 1st Ave. National Building, immediately behind the Alexis, listed in LPB-49/81 as 1006-1024 Western Avenue and in the Department of Neighborhoods listing as 1018 Western Ave. Coleman Building, listed in LPB-49/81 as 94-96 Spring Street. This building was across Spring Street to the north of the Alexis Hotel. Only the terracotta exterior survives, as the lower portion of the exterior of the Watermark Tower, built 1983 (see ). The Department of Neighborhoods listing gives this the presumably erroneous address of 95 Spring St (possibly a side entrance to the Alexis, possibly entirely fictitious) and calls it the "Colman Building," the name of an entirely distinct building several block south at 801-821 First Avenue. Grand Pacific Hotel, not listed in LPB-49/81, but another hotel building of the same vintage, between the Coleman/Watermark building and the Colonial Hotel. The Department of Neighborhoods listing gives this as 1116 1st Ave, but the building is actually at 1115 First Avenue.
