Replacement of the pool or spa shell is considered to be construction of a new facility and shall be processed as such. Resurfacing the pool interior to original nontoxic, slip-resistant and smooth specifications is considered a repair or alteration. Equivalent replacement of equipment is not considered a repair or alteration. The following items shall be addressed during resurfacing projects:
The lip of the gutter must be leveled to within 1/4 inch (6.4 mm) between the highest and lowest point and the downward slope from the lip to the drain must be maintained as originally designed or increased, but shall not exceed new construction standards.
Tile step markings must be installed meeting the requirements of Section 454.1.2.5.3.
Where applicable, the slope break marking must be installed meeting the requirements of Section 454.1.2.2.3.2 and safety line must be installed 2 feet (610 mm) before the marking.
Depth markers and NO DIVING markers must be installed in accordance with Section 454.1.2.3.
The pool ladder must have a 3 to 6 inch (76 to 152 mm) clearance from the pool wall. New cross-braced ladder(s) shall be installed in place of noncross-braced ladder(s) in conformance with Section 454.1.2.5.1 during a pool resurfacing.
Should resurfacing works affect the step riser heights, no riser shall exceed 10 inches (254 mm) for pools and 12 inches (305 mm) for spas, and the intermediate risers shall be made uniform.
Step treads that protrude from the pool wall shall be removed and replaced with a crossbraced ladder or reconstructed to meet the requirements of Section 454.1.2.5.1 or 454.1.2.5.2.
