Ladd Tower, Modern residential tower in Portland, United States

Ladd Tower is a 23-story residential high-rise at 240 feet (73 m) in downtown Portland, completed in 2009. The tower rises from a base that shares its first three floors with an adjacent church, and its upper floors are set back 27 feet from the fourth story. It holds 332 rental apartments and ground-floor commercial space.

The building was completed in 2009 after the neighboring Ladd Carriage House was moved from its foundation in 2008 and later returned to its original location. This relocation allowed construction of the tower on the site.

The tower is named after William S. Ladd, an early Portland politician and developer. Its first three floors are shared with the adjacent church, and the ground floor holds commercial space managed by Holland Residential. The Ladd Carriage House, moved off its foundation during construction, returned beside the tower in October 2008.

Ladd Tower is a private residential building, so the apartments and upper floors are not open to visitors; only the ground-floor commercial space is entered by the public. The tower stands on the South Park Blocks, and the Ladd Carriage House, moved off its foundation during construction and returned in October 2008, stands directly beside it and can be seen from the sidewalk.

The original project planned for 189 condominiums but shifted to rental apartments in 2007, leading to a redesign that increased the number of floors while keeping the same total height. This unusual adjustment allowed for more living units within the same footprint.
