How to read this

These figures are the project values applicants declared to the Los Angeles permitting office, which uses them to calculate permit fees. Declared values tend to sit below the final invoice, and jobs done without a permit are not counted at all. Read the median as a floor for a permitted window replacement job in Los Angeles, then check it against the sourced national range and get local quotes.
