Water heater installation cost by job.
Installed-labor pricing for Altadena, adjusted for local rates. Relocations and gas-line upgrades add to the base.

Local labor rates reflect the area's median income of $123,869, and all installations must comply with the California Plumbing Code, including seismic strapping per Health & Safety Code 19211.
