Trinity Place Apartments

Trinity Place Apartments is a residential complex in Northwest Portland featuring red brick walls and white stone-trimmed bay windows arranged in a U-shaped layout. The design allows abundant natural light to reach the living units while showcasing early 20th century craftsmanship.

The building was constructed in 1911 by architect William C. Knighton and represents Nob Hill's shift from single-family homes to apartment living. This period reflected a larger change in how Portland's urban residents chose to house themselves.

The building shaped Portland's housing evolution by offering residents larger apartments with private kitchens, marking the end of boarding house living. This innovation allowed many people to experience more comfortable domestic spaces.

The building underwent a major seismic reinforcement in 2017 that modernized its safety systems. Visitors should understand that substantial structural improvements lie beneath the historic exterior.

Many units retain original features such as claw-foot tubs, hardwood floors, and ornamental glass doors that preserve the character of the era. These details offer a glimpse into how early 20th century residents lived.
