Water heater installation cost by job.
Installed-labor pricing for Hillsborough, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Hillsborough, where the median home was built around 1970 and homeownership is high at 86.3%, water heater installation is a common upgrade. Typical costs for a standard tank installation range from $750 to $1,700, while tankless units run $1,700 to $4,200 or more, plus $275 to $950 for a new gas line.

Permits are required under the California Plumbing Code, and seismic strapping is mandatory per state law.
