What changes the price
Location
the median ranged from $20,935 in San Francisco to $27,375 in Seattle.
Project scope
the high end of the range is more than double the low end, so size, access, tear-off of old material and finish level matter as much as location.

Where do these numbers come from?
From building permits that U.S. cities publish on their open-data portals. Each permit includes the project cost declared by the applicant. We filter residential projects of this type and report the 25th percentile, median and 75th percentile.
Why might my quote be higher than these figures?
Permit applicants declare the cost themselves and some understate it. Permits also exclude work that does not need one. Treat the high figure as a realistic ceiling for an average project, not a maximum.
