In order to protect unattended children from the risk of drowning: 1. All below-ground outdoor swimming pools, hot tubs, or spas having a depth of eighteen (18) inches or greater at the deepest point shall be completely surrounded by a fence or wall with a height of no less than four (4) feet... 2.

Full Breakdown
Under LDO § 5.3.4(I), any below-ground outdoor pool, hot tub, or spa at least 18 inches deep must be fully enclosed by a 4-foot fence or wall with no gap wide enough for a 4.5-inch sphere to pass through. Above-ground pools are exempt from that fencing rule but must still have gates at every access point, and all required gates need self-closing, self-latching hardware kept shut when not in use. A portable spa or hot tub with an ASTM ES13-compliant safety cover is exempt from these requirements entirely. Accessory pool equipment must also meet the setback standards for accessory structures in Table 6.3-1.
Violations & Fines
Cary's Planning Department can require compliance before permitting pool construction; an unenclosed or ungated pool is a Land Development Ordinance violation subject to zoning enforcement.
