## What a water heater replacement permit usually covers

Removing the old heater and setting a new tank or tankless unit, with the venting, gas or electric hookup and earthquake straps the permit inspects. Moving the heater to a new spot, new gas lines, drywall repair and haul away are often priced separately or not listed on the permit.

Read this first. Permit values are self-reported by the applicant to set permit fees. They often leave out materials or labor, and they are not what the contractor actually charged. A quote above or below this range can be reasonable.
