[1] One June 21, 1821, Jose Antonio Carrillo petitioned the Comisionado for a house lot near the "new Temple which is being built for the benefit of our holy religion."
This is the only record of a grant of a house lot made between 1786 and 1836—just one real estate transfer in fifty years.
When Lieutenant Edward Ord made his plan of the City of Los Angeles in 1849, he took as the initial point of his survey the northwest corner of Carrillo's house that stood on this lot; and his bearings from a point opposite that corner gave direction to the lines of the city's streets, and virtually to the plan of the city.
It was the most pretentious and aristocratic residence in the Pueblo de Los Ángeles at that time.
It featured wings extending back on Main Street, and from its eastern end, to an adobe wall in the rear, thus enclosing a patio or inner court.
