Lake San Marcos is unincorporated San Diego County land, and the City of San Marcos surrounds it on every side. Mail reads San Marcos, CA 92078, while the Census and the County use the name Lake San Marcos. That split decides which name Google and AI tools see in your listings, and for trades that pull permits, which office signs off on the work.
