How to Build an ADU In The Gregory Ain Mar Vista Tract HPOZ

Updated: Feb 15, 2023

Gregory Ain Mar Vista Tract

Mar Vista Housing is also known as the Gregory Ain Mar Vista Tract. It is located in west LA and consists of 52 homes designed by architect Gregory Ain. Built in 1948, this one-story single family residential development was shaped by the Fair Housing Administration’s desire to promote home ownership among modest-income families and the need to accommodate the growing number of defense/aircraft industry employees. Landscape architect Garrett Eckbo used a large number of planting materials from varying climates to create a park-like atmosphere along the streets, opening up space between houses to allow for more spatial social interaction, as opposed to creating boundaries and fences. These unique design elements allowed the Advance Development Agency to market Mar Vista Housing as “Modernique” to exemplify the development’s modern and unique design features. The Mar Vista Tract is the City’s first post-World War II HPOZ and was adopted by the City Council in 2003.

The market for ADUs is trending in the Mar Vista Tract because the architect who designed the neighborhood envisioned a park-like setting without fences or walls, with generous front setbacks and common backyards. He used a wide variety of trees and plants to create a lush, complex environment, including garden spaces between houses and even planting different kinds of fruit trees in each backyard to encourage neighbors to get together to swap fruit. The result is an unusually harmonious group of single-family residences, joined together by the free-flowing landscape and unified by their common architecture. Their current owners are actively working to return altered homes to their original appearance and pride themselves on preserving a truly vibrant and functional Mid-Century Modern neighborhood.
