Water heater installation cost by job.
Installed-labor pricing for South Lyon, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In South Lyon, Michigan, where the median home was built in 1991, many homeowners face water heater replacements that must comply with local codes. A standard tank installation typically costs between $700 and $1,600, while a tankless unit runs $1,600 to $4,000 or more. Adding a new gas line can cost $275 to $900. Because South Lyon has cold northern winters and cold inlet water, gas water heaters are the recommended choice for reliable performance.

These permit fees and code requirements affect the final installation cost.

The price of a water heater installation in South Lyon depends on the unit type (standard tank vs. tankless), the need for a new gas line, and permit fees.
