Kaiser Permanente Building, high-rise office building in the Lloyd District, Portland, US

The Kaiser Permanente Building, also called the Lloyd 500 Building, is a 16-story high-rise at 500 Northeast Multnomah Street in Portland's Lloyd District. Construction began in 1972 and was completed in 1974.

The organization behind this building started in the 1930s providing medical services to industrial workers. Over the decades it expanded into a large healthcare network operating across the country.

The building is named after Kaiser Permanente, the health-care organization that occupies it, and is also called the Lloyd 500 Building after its address at 500 Northeast Multnomah Street. Its name ties the tower to both its tenant and the Lloyd District street grid.

The building stands at 500 Northeast Multnomah Street in the Lloyd District, a short walk from the Lloyd Center area and served by nearby light rail and bus lines. Its 16 floors were built between 1972 and 1974, so visitors should expect a 1970s office tower rather than a public clinic. Access is through the Multnomah Street entrance.

The building is also called the Lloyd 500 Building, a name taken from its address at 500 Northeast Multnomah Street in the Lloyd District. Construction ran from 1972 to 1974, and the tower rises 16 stories.
