I’ve not seen any street addresses, just house names, in my few dozen trips where I have walked through Carmel-by-the-Sea.

I feel bad for map developers. Searching Google Maps for Carmel House yields a house at 26177 Scenic Rd, not the house at the above link.
Within Carmel-by-the-Sea, some addresses on Zillow are like "Lincoln 7sw 13th," but that address is not known to Google Maps.

Certain addresses on Zillow appear to be in standard form, such as 225 The Crossroads Blvd, Carmel, CA 93923, but notice the URL isn't Carmel-by-the-Sea. EDIT: Nevermind, that address is clearly erroneous, the house is on Delores St.

Putting that address into Google Maps returns a location in The Crossroads Shopping Center, not the location in Zillow.
Years ago, I had to routinely redo my searches for Carmel addresses, since Google Maps assumed I was referring Carmel Valley near San Diego, zip 92130, not Carmel-by-the-Sea. That changed at some point; Carmel now "redirects" to Carmel-by-the-Sea. There is also a Carmel Valley zip 93924, east of Carmel-by-the-Sea.
