Summary
Portland treats any pool holding water over 24 inches deep as a swimming pool, above-ground included, and the code carves out a specific exception: unlike an ordinary fence of the same height, the barrier around it always needs a permit.
Fences constructed of wood and similar materials not over 7 feet (2134 mm) high, fences constructed of masonry, concrete and similar materials not over 4 feet high, and typical field fencing not over 8 feet (2438 mm) high when constructed of woven wire or chain link. Exception: all barriers around swimming pools require a permit.
2. Retaining walls that are not over 4 feet in height measured from the bottom of the footing to the top of the wall, except where the retaining wall supports ascending slopes exceeding 3:1 or where the retaining wall supports a nonsoil surcharge.
3. Water tanks supported directly upon grade if the capacity does not exceed 5,000 gallons (18,927 L) and the ratio of height to diameter or width does not exceed 2 to 1.
4. Swings and other playground equipment.
5. Ground mounted photovoltaic systems 10 feet (3038 mm) or less in height measured to the highest point of the installation when no public access is permitted beneath the structures.
Full Breakdown
City Code Section 29.10.020 RRR defines a swimming pool as any structure for swimming or recreational bathing with water over 24 inches deep, expressly including above-ground and on-ground pools alongside in-ground ones. Section 24.10.072 B.1 exempts ordinary wood fences up to 7 feet and masonry fences up to 4 feet from permitting, but immediately carves out an exception: all barriers around swimming pools require a permit regardless of height. In-ground pool construction is separately listed as permit-required work under 24.10.072 A.18.
Violations & Fines
Building or erecting a structure, including a pool barrier, without the required permit is unlawful under Section 24.10.060 D. The City Administrator can issue a stop work order halting construction until compliance is shown, and pursue remedies under Code Chapter 3.30.
