What do Tacoma water heater permits declare?
Each Tacoma figure above is a declared permit value: what the applicant told the permit office the water heater replacement job was worth when applying. It is not an invoice.
The records come from City of Tacoma, Planning and Development Services (Tacoma Open Data).
The selection keeps permits with the Residential subtype whose descriptions match the job. Exact duplicate selected rows are removed before classification.
Before matching, the selection left out 38 permits for a new dwelling or work not on an existing home, 1 permit for legalisation, as-built work, revisions, supplements or renewals, and 71 permits whose descriptions also named another job.
Of the 1,128 matched permits, 1,126 carried a declared value. The low-value check removed 3 records, leaving 1,123 permits behind the figures.
