History and architectural features

The name of the building remains the same, even though its usage has altered over time. The name changed from the Penn Alto Hotel to Penn Alto Apartments when it changed from strictly being a hotel to a residential hotel, which rents both apartments and hotel rooms.^[2] The current name is City Hall Commons, deriving its name from its proximity to City Hall, which is just across the street.

The building, which was designed by the H.L. Stevens & Company and built in 1921, was added to the National Register of Historic Places in 1989. It is located in the Downtown Altoona Historic District.

Official measurements of the building conflict with each other. One measurement is as conservative as 98 feet (30 m), while another lists it as 115 feet (35 m). These variations may be due to the slight incline that the Penn Alto was built on.
