Show full citationHideSAMMAMISH DOES NOT PUBLISH ITS PERMIT FEE AMOUNTS IN THE CODE - THIS ENTRY DECLINES TO STATE A FIGURE RATHER THAN INVENT ONE. SMC 16.20.340 directs the reader to "the fee schedule as established in the City of Sammamish fee resolution", which is a separate council instrument not read for this entry. WHAT THE CODE DOES FIX IS A FLOOR, AND IT IS AN UNUSUAL ONE: "In no case shall the building permit fee be less than the City's hourly inspection fee multiplied by the number of inspections expected to be performed for work authorized by the permit." The minimum is therefore tied to an expected inspection COUNT, not to a dollar amount - which matters here because the city publishes twelve required inspection stages. Plan review is a SEPARATE and ADDITIONAL fee (SMC 16.20.345), payable when submittal documents are lodged; the permit centre may take a deposit in lieu where the full amount is not yet known, applied against the total. Incomplete or changed submittals, and deferred submittal items, draw a further plan review fee. A reinspection fee may be assessed where work is not complete or previous corrections were not made (SMC 16.20.450). |
