Water heater installation cost by job.
Installed-labor pricing for Larkspur, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Larkspur typically costs between $750 and $1,700 for a standard tank model, and $1,700 to $4,200+ for a tankless unit, including labor and materials. With many homes built around 1971, older plumbing and gas lines may require upgrades, adding $275–$950 for a new gas line. California's strict codes mandate seismic strapping and, on closed systems, an expansion tank. Given Larkspur's mild Mediterranean climate and moderate inlet water temperatures, a heat-pump water heater is a recommended choice, and the federal 25C tax credit can offset 30% of its cost (up to $2,000). Permits are required for all installations, and local contractors are familiar with these requirements.
