Krotoszyner, Dr. Martin M., Medical Offices and House
.JPG){kind=link}
Why it's listed
Built in 1911-12 at the corner of Sutter and Hyde Streets in San Francisco, this three-story building combined a physician's office with his family home. Architect Herman Barth designed it with a reinforced concrete structure, street facades of mottled gold-to-rust tapestry brick, and ornamental terra cotta balconies, door trim and curved pediments. Inside, the ground-floor offices keep wood-grain painted woodwork, tiled fireplaces and stained glass, and the stairwell windows show Prairie School influence. The building was home to Dr. Martin Krotoszyner, a urologist credited with bringing the cystoscope to San Francisco in 1894, who led urology departments at several hospitals and the San Francisco Polyclinic and trained many of the city's urologists. His family lived here until 1937-38, and later doctors used the building for medical practice. It was listed as an exceptional example of post-1906 Beaux Arts design and as a rare surviving office-residence building type.
Significance in brief: The building is an excellent example of City Beautiful/Beaux Arts Classicism from the rebuilding after the 1906 earthquake and fire, with exceptional mottled brick and terra cotta detailing. It housed Dr. Martin Krotoszyner, a pioneering urologist who brought the cystoscope to San Francisco and trained many of the city's urologists. It is also a rare surviving example of a combined doctor's office and residence type in the Tenderloin.

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.
