Noe Valley was primarily developed at the end of the 19th century and at the beginning of the 20th century , especially in the years just after the 1906 San Francisco earthquake . As a result , the neighborhood contains many examples of the " classic " Victorian and Edwardian residential architecture for which San Francisco is famous . As a working-class neighborhood , Noe Valley houses were built in rows , with some of the efficient , low-cost homes being more ornate than others , depending on the owner 's taste and finances . Today , Noe Valley has one of the highest concentration of row houses in San Francisco , with streets having three to four and sometimes as many as a dozen on the same side . However , few facades in such rows of houses remain unchanged since their creation in the late 19th and early 20th century
