Apex FAQ
How tall must my pool fence be in Apex?
At least 48 inches above grade, measured on the side facing away from the pool, per NC Residential Code Appendix V, Section AV105.2 Item 1. The maximum vertical clearance between grade and the bottom of the barrier is 2 inches (or 4 inches where concrete or fixed solid material is used).
Do gates need to be self-closing in Apex?
Yes. NC Residential Code AV105.2 Item 8 requires that 'Pedestrian access gates shall open outward away from the pool and shall be self-closing and have a self-latching device. Gates other than pedestrian access gates shall have a self-latching device.'
Can Apex require a 6-foot pool fence instead?
No. NC Session Law 2023-108 (HB 488, 2023) reorganized the Building Code Council and Residential Code Council and limits local amendments to the NC Residential Code. Apex applies the State Building Code Council's 48-inch standard from Appendix V/NC-A as written.
Cary FAQ
Can North Carolina cities require taller pool fences than state code?
Generally no. The NC Building Code is a uniform statewide standard under N.C.G.S. 143-138, and local amendments must be approved by the Building Code Council and cannot conflict with statewide minimums.
Do above-ground pools need barriers in North Carolina?
Yes, if the water depth exceeds 24 inches. The pool wall itself may serve as the barrier if at least 48 inches high, with ladders that are removable or lockable when unattended.
