Every figure here is the job value written on the city permit, not the price paid. Permit values usually run below the final price, so get more than one quote. Values under $1,000 are placeholders and are left out. Median and middle half: half of the jobs were valued above the median; the middle half runs from the 25th to the 75th percentile.
