Sepulveda House

The Sepulveda House emerged in 1887 as the ambitious project of Señora Eloisa Martinez de Sepulveda, a widow from Sonora, Mexico who had arrived in Los Angeles decades earlier and found herself independently financing an $8,000 commercial venture after her husband's death. She deliberately chose American architects George Costerisan and William Merithew to design what would become a remarkable hybrid building, signaling her embrace of American business practices while maintaining her cultural identity. The structure served as both investment property and residence, with commercial storefronts generating rental income and upper-floor bedrooms housing paying boarders.

The building's Eastlake Victorian design, drawn from pattern book architecture distributed through national catalogs, represents one of the last surviving examples of this style in Los Angeles today. Its most distinctive feature is the covered breezeway that separates the two Main Street commercial spaces from the private dwelling rooms facing Olvera Street, creating a physical manifestation of bicultural identity. The 22-room structure combines American brick construction with traditional Mexican courtyard principles, while Señora Sepulveda's own three private rooms revealed this cultural layering through their mix of mass-produced American furniture, Chinese textiles, Catholic religious shrines, and multiple wallpapers.
