Summary
Cupertino requires a building permit to construct or install a residential swimming pool, with only a narrow exemption for small prefabricated above-ground pools. A pool is exempt only if it is accessory to a single-family or duplex home, less than 24 inches deep, no larger than 5,000 gallons, and installed entirely above ground; anything larger or in-ground needs a permit.
[A] 105.2 Work exempt from permit. Exemptions from permit requirements of this code shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this code or any other laws or ordinances of the City of Cupertino. Permits shall not be required for the following: ... Prefabricated swimming pools accessory to a group R-3 occupancy that are less than 24 inches (610 mm) deep, are not greater than 5,000 gallons (18,925 L) and are installed entirely about ground.
Full Breakdown
2 lists the work exempt from that permit requirement. Among the general exemptions for accessory structures like small tool sheds and low retaining walls, the code carves out a narrow swimming pool exemption: prefabricated swimming pools accessory to a Group R-3 occupancy, meaning a one- or two-family home, are exempt from a building permit only if they are less than 24 inches deep, hold no more than 5,000 gallons, and are installed entirely above ground. 1 permit requirement and needs a building permit before construction begins.
2 also makes clear that even an exempt pool is not authorized to violate any other code provision or city ordinance simply because it skips the permit step. 140 also apply before the project can receive final approval.
Violations & Fines
Building a pool that exceeds the narrow prefabricated exemption's depth, volume or above-ground limits without first obtaining a permit is unpermitted work subject to the general unlawful-acts and penalty provisions adopted at Chapter 16.04.130, and the Building Official can issue a stop-work order under Section 115 and require correction, inspection and permitting after the fact before the pool can be used.
