Go to a regular google maps page and zoom in as far as you can.
It shows building details for many (but not all) locations.
Not sure you you get from there to an SVG.
There is also the open street map project (i.e. https://www.openstreetmap.org/#map=17/47.62253/-122.35258&layers=H)
Which will export a file to their own .osm format and you can convert that directly to SVG!
