Summary
Wilmington requires a building permit before any residential swimming pool goes into the ground, because City Code Section 18-50 treats a pool as a 'structure' whose construction cannot start without a permit from the city manager's designee or the New Hanover County Inspections Department. Zoning setback rules in Section 18-308 and a fencing mandate in Section 6-18 both feed into that permit review.
(a)Except as provided in G.S. § 160A-417 and the state building code, no person within the city shall commence or proceed with any of the following activities without first applying for and receiving from the city manager or designee and/or the county inspections department, as appropriate, one (1) or more permits covering all such work or changes:(1)The construction, reconstruction, alteration, repair, moving or demolition of any building or structure;
Full Breakdown
Section 18-50 of the Land Development Code, adopted by Ordinance No. O-2008-25 on April 8, 2008, bars anyone in the city from starting 'the construction, reconstruction, alteration, repair, moving or demolition of any building or structure' without first applying for and receiving a permit 'from the city manager or designee and/or the county inspections department, as appropriate.' The code's definitions section describes a swimming pool as 'an inground or aboveground pool for swimming,' with inground pools limited to no more than twelve inches of coping above the surrounding finished grade, so a new residential pool falls squarely inside the structure category that Section 18-50 covers and cannot be excavated, poured, or installed before that permit issues. Because Wilmington contracts building inspections to New Hanover County (County Code Section 5-44 et seq.), the construction permit itself is typically pulled through the county inspections department, while the city's Section 18-50 review confirms the plans conform to the zoning chapter before approval.
Section 18-308 sets the zoning conditions a pool must satisfy: it has to sit in the side or rear yard, cannot extend past the front facade of the principal structure (or, on a corner lot, past the side facade facing the street), and in the R-20, R-15, R-10, R-7, R-5 and R-3 residential districts must be set back at least ten feet from the rear property line and ten feet from the side line, or the district's minimum side yard if that figure is smaller. In-ground pools do not count toward a lot's cap on accessory buildings, but in-ground and above-ground pools, plus their surrounding decking, do count toward the lot's maximum coverage limit.
Section 6-18 layers on a safety condition: any permanent outdoor pool with water eighteen inches deep or more must be 'completely surrounded by a fence or wall not less than four (4) feet in height,' with commercial pools and pools at hotels under constant surveillance exempted.
Violations & Fines
Building or altering a pool without the Section 18-50 permit, or outside the site plan it approves, exposes the owner to Section 18-52's civil penalties: $100 for the first violation and $200 for each later one, with every day the unpermitted work continues counted as a separate offense. The city may also withhold or revoke the permit and order work stopped under the state building code. An unfenced pool under Section 6-18 first draws written notice and up to ninety days to install the required fence before it is treated as a violation.
