Water heater installation cost by job.
Installed-labor pricing for San Marino, adjusted for local rates. Relocations and gas-line upgrades add to the base.
San Marino homeowners typically pay $750–$1,700 for a standard tank water heater installation and $1,700–$4,200+ for a tankless unit, with an additional $275–$950 if a new gas line is needed. Because most homes were built around 1942, older plumbing and gas lines may require upgrades to meet current California codes. Permits are mandatory, and seismic strapping is required by state law. Given the mild Mediterranean climate and moderate winter inlet water temperatures, a heat pump water heater is a strong fit and qualifies for the federal 25C tax credit (30%, up to $2,000).
