Full Breakdown
Under the general permit-required rule (Olathe Municipal Code §15.02.120 [A]105.1), constructing a pool needs a building permit. The only exemption, at §15.02.140 [A]105.2 item 9, covers prefabricated above-ground pools accessory to a single-family or duplex home that are less than 24 inches deep and hold no more than 5,000 gallons. In-ground pools, deeper pools, or larger above-ground pools all need a permit. Installation itself is governed by the 2018 International Swimming Pool & Spa Code as locally adopted at Chapter 15.20 (§15.02.080 [A]101.4.9), and the installer generally must hold a current Johnson County contractor's license unless the owner occupies the home and does the work personally.
Violations & Fines
Building or altering a pool without the required permit is a code violation; the Building Official can stop work, deny further permits under §15.02.150, and refer the matter for misdemeanor prosecution under the code's general penalty provisions.
