From our cross-city data studies: the same measure, read the same way, for every city we cover.
Source: City of Aspen building permits on single-family, duplex and multi-family homes (the City's permit map layer; permits filed by architects or design firms, about 39% of building permits, are left unattributed because those firms aren't the contractor), with home values from the Pitkin County Assessor. The window is October 2023 through September 2026; a permit filed after that isn't here yet.
A filed value is what the contractor wrote on the permit when they applied. It is not a quote and not the final bill.
Counts are permits, not jobs: one job can need several permits, and one permit can cover several visits.
