Summary
Wilmington adopts the 2018 International Swimming Pool and SPA Code by reference, setting the safety, barrier, and construction standards that govern every residential and public pool built or altered in the city.
There is hereby adopted by the city for the purposes set forth in section 4-1 and to establish provisions applicable to the construction, addition, alteration, removal, demolition, maintenance, accessibility, use, occupancy, location and maintenance, of buildings (new or existing), structures and premises, together with provisions applicable to fuel gas, energy, swimming pools, and equipment, those certain codes known as The International Building Code of 2018, The International Fuel Gas Code of 2018, The International Mechanical Code of 2018, The International Plumbing Code of 2018, The International Fire Code of 2018, the International Swimming Pool and SPA Code of 2018, the ICC/ANSI A117.1-2017 Accessibility Code of 2017, The International Energy Conservation Code of 2018, The International Existing Building Code of 2018 and The International Property Maintenance Code of 2018, copies of which have been and are now on file in the City Clerk's Office, and which are incorporated in this chapter and subchapter by reference, and all of the nationally recognized standards referred to and incorporated into those codes, together with any and all supplements thereto, but except such articles and sections that are deleted, modified, or amended and as otherwise set forth in this chapter and subchapter, are adopted as the building code of the City of Wilmington.

Full Breakdown
The City Code (§ 4-26) folds the International Swimming Pool and SPA Code of 2018 into Wilmington's building code, so pool barriers, entrapment-avoidance drain covers, and equipment standards from that model code are enforceable local law, not just state guidance. The Department of Licenses and Inspections administers it under the Commissioner of Licenses and Inspection. Building-permit rules under § 4-27 require pool plans to show dimensions, distances to lot lines, buildings, walks and fences, plus water supply, drainage, and depth details (§ 107.2.1.2), and every in-ground pool needs a site plan regardless of size.
Violations & Fines
Violating the adopted building and pool code brings fines of $250 to $1,000 for a first offense, $500 to $2,500 for a second, and $1,000 to $5,000 for a third or later offense, with optional community service (Code § 4-3).
