What the job includes, the line items to ask for and how to compare bids: the national water heater replacement cost guide.
What do Kansas City water heater permits declare?
Each Kansas City figure above is a declared permit value: what the applicant told the permit office the water heater job was worth when applying. It is not an invoice.
The count covers residential permits on existing one- and two-family homes whose description matches a water heater replacement. Permits for a new dwelling or not on an existing home, and permits that also name another job, were left out first.
All 1123 matched permits carried a declared value. Six values fell below the low-value floor for this job and were removed, which leaves the 1117 permits behind the figures.
A heater replaced without a permit is not in the Kansas City count, so these figures describe permitted water heater work only.
How does Kansas City compare with the national survey?
For the national picture, the Census Bureau's American Housing Survey asked households about the work done on their home and whether they hired it out. Its item reads "Added or replaced water heater", one line for every kind of heater. It does not split tank from tankless or gas from electric, so the national range spans all of them.

| What was measured | Median | Typical range (middle half) |
|---|---|---|
| Water heater jobs that American Housing Survey households paid a plumber or installer to do had | a median of $1,300 | the typical range (middle half of 1,522 American Housing Survey data points, the United States, 2021-2023) was $850 to $2,000 |
| When the household fitted the heater itself | a median (671 American Housing Survey data points, the United States, 2021-2023) of $700 | — |

Full national guide: How much does water heater replacement cost?
The Kansas City median declared value sits above the national survey median for hired-out water heater jobs.
The two are different kinds of record: a survey answer is what a household remembers paying, while a permit value is what an applicant wrote down before the work began. This page keeps them apart and never blends them into one number.
What does ENERGY STAR say about permits?
ENERGY STAR's buying advice for water heaters says to check that the company will obtain a local permit where one is needed and understands local residential building codes.
