Why it's listed

This two-story stucco house at 1340 Woodstock Road in San Marino, California, was built in 1925 and designed by Joseph Kucera, who drew many residential plans in the Los Angeles area. It is described as a good example of the 1920s California Mission Style, though not of national architectural importance. The first floor holds an entry hall, living room, dining room, library, kitchen, maid's room and bath, with two bedrooms and a bath upstairs. It was the home of astronomer Edwin Powell Hubble from 1925 until his death in 1953, and it stayed in the family until about 1973. Working at the Mount Wilson and Palomar observatories, Hubble showed that the Milky Way is only one of countless galaxies, created a classification scheme for them known as the tuning fork, and demonstrated that galaxies are moving apart, a finding tied to Hubble's constant. The house remains unaltered, well maintained and in use as a private residence.

Significance in brief: The house was the home of astronomer Edwin Powell Hubble from 1925 until his death in 1953. Hubble proved that the universe contains countless galaxies beyond the Milky Way, devised a classification system for them, and showed that they are receding from one another. The nomination argues the house is significant for its association with him, not for its architecture.

What listing means for this property

National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).

Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.

General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
