Ladd's Addition is an inner southeast historic district of Portland, Oregon, United States. It is Portland's oldest planned residential development, and one of the oldest in the western United States.[1] The district is known in Portland for a diagonal street pattern, which is at odds with the rectilinear grid of the surrounding area. Roughly eight blocks (east-west) by ten blocks (north-south) in size (by reference to the surrounding grid), Ladd's is bordered by SE Hawthorne, Division, 12th, and 20th streets. It is part of the Hosford-Abernethy neighborhood association.
