Oakland County, MI Swimming Pools & Spas: Above-Ground Pools (2026)

Under Appendix G of the Michigan Residential Code (enforced by every Oakland County building department), an above-ground pool more than 24 inches deep is a 'swimming pool' and must meet barrier requirements. When the pool structure itself serves as the barrier, the top of the pool wall must be at least 48 inches above the surrounding grade. Removable or lockable access ladders must be removed, secured, or covered when the pool is not in use to prevent unauthorized child access. If a deck is built around the pool, the deck perimeter becomes the barrier and must meet the 48-inch height rule with a self-closing, self-latching gate. Above-ground pools require a local building permit in nearly every Oakland County municipality, including Royal Oak, Troy, Farmington Hills, Waterford, and Rochester Hills, regardless of whether they are inflatable, soft-sided, or steel-walled. Electrical permits are required separately for pump motors, heaters, and pool lighting under the Michigan Electrical Code, which requires GFCI protection on all pool-related circuits and bonding of metal components within 5 ft of the water.
