Even the city-issued signs disagree about the correct spelling of the Victorian-era neighborhood next to Echo Park. Madalyn Rofer-Choate sent in this photo of the signs at Bellevue Avenue and East Edgeware Road that spell the neighborhood name two ways: Angeleno with an “e” and Angelino with an “i. While it seems that the neighborhood name is most often spelled Angelino Heights, there are still plenty of examples of Angeleno Heights as well.
Old tract maps, for example, show the name spelled “Angeleno” with an “e” but the city’s Office of Historic Resources uses “Angelino” with an “i.” The neighborhood’s Wikipedia entry for Angelino Heights said the neighborhood’s name was originally spelled Angeleno. A history piece in L.A. Magazine title “CityDig: The Living History of Angelino Heights” goes on to spell the name both ways.
The Eastsider, by the way, prefers Angeleno Heights.
