Fee schedule

Chapter 16.04 provides for "the issuance of permits and collection of fees" without setting them, and OMC Title 15 is a whole separate title called IMPACT FEES which was NOT opened for this entry - so a figure is declined rather than invented, and the reader is pointed at the title most likely to carry it. WHAT THE CHAPTER DOES FIX IS THE RENEWAL RULE, AND IT IS UNUSUAL: where a permit has expired, a new one must be obtained and "the fee therefor paid based on the work left to complete the project" - a renewal priced on the PERCENTAGE OF INCOMPLETE WORK rather than a flat charge, so the later you let it lapse the less the replacement costs. That is the opposite of the intuition most owners bring.

Inspection process

    Tips

    • The 180-day clock is measured by the gap between REQUIRED INSPECTIONS - an inspection is what restarts it
    • If a permit lapses, the replacement is issued under the codes current AT RE-ISSUANCE, and Olympia follows the state's current edition rather than a fixed year
    • A renewal is priced on the percentage of INCOMPLETE work
    • Fee amounts are not in the building title; OMC Title 15 is a separate IMPACT FEES title

    Frequently asked questions

    Often not. Olympia requires sprinklers to protect all areas of a dwelling unit, but exempts "Detached garage conversions to accessory dwelling units and detached accessory dwelling units with utilities served by an existing single-family residence that does not have an existing sprinkler system". Note this is an Olympia answer only - Camas applies its residential sprinkler requirement to new detached ADUs, so the two cities differ on the same question.

    Olympia names no edition year. OMC 16.04.020 adopts "The current State adopted edition" of the International Building Code, International Residential Code and International Mechanical Code, as adopted by the State Building Code Council in Chapters 51-50, 51-51 and 51-52 WAC. The only year in the adoption belongs to the accessibility standard, ICC A117.1-2017.

    You need a new one, and it may be judged against a different code. A permit expires if work has not commenced within 180 days, or if work is suspended or abandoned for at least 180 days - measured by the length of time between required inspections - and in any case after eighteen months from issue where work is ongoing but incomplete. On expiry "a new permit shall first be obtained" and "Any new permit shall comply with the provisions of the codes currently adopted at the time of permit issuance". Because Olympia adopts the current state edition rather than a fixed year, that can mean a later edition than the one you designed to. The fee for the replacement is based on the work left to complete.
