What Auburn's numbers say about plumbing
Auburn is one of the most established suburbs tracked here — 13,847 people (2025 estimate), up just 0.5% since 2020[2]. It covers 7.2 square miles (1,929 residents per square mile, the 12th densest), sits entirely in Placer County, in ZIP code 95603[3].
With 4% of homes built since 2010 and 52% before 1980[1], Auburn's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.
95603 is the city's single ZIP code[6].
Nearest of the other suburbs we track: Rocklin (11.1 mi SW), Lincoln (11.7 mi W) and Roseville (15.7 mi SW)[3].
