• Why is this different from the per-square-foot prices I see online?Online prices are quoted per square foot. A filed value is one number for the whole job on one permit, often many square feet plus the work around them, and the Cambridge file does not record how many each job covered, so we can't turn $37,120 into a price per square foot.
• Do bigger houses get bigger bills?In the file, yes for the firms: those working on the upper third of homes by value usually file $45,000, the lower third $36,235. That is firms, not single jobs.
