Here's another possible approach:

If someone knows the name of Henry Frick's coachman or chauffer (might be
in his will), locating that person in the 1900 census or a 1914 city
directory would probably give you the stable/garage location. Most
coachman's families lifed above or adjacent to the stable. This probably
true of chauffers as well
