Swimming Pool Inspection Checklist – InterNACHI Inspection Narrative Library

ISPSC Residential Pool Barrier Reference

Use this as a quick-reference note in the Safety Barriers and Access section. Local amendments may modify these dimensions, so field verification against the adopted code is still required.

Minimum barrier height: 48 inches, measured on the side of the barrier away from the pool.
Maximum clearance at bottom over non-solid surface: 2 inches.
Maximum clearance at bottom over solid surface: 4 inches.
Maximum opening size in barrier: 4 inches.
Minimum latch height: 54 inches above grade, located on the pool side of the gate.
Gates should be self-closing and self-latching, and should swing away from the pool.
Mesh barrier installations should be at least 20 inches from the water’s edge to the inside face of the barrier.

SWIMMING POOL INSPECTION CHECKLIST

General Information^[1]

☐ Verify property address and pool location
☐ Identify pool type (in-ground, above-ground, indoor)
☐ Determine pool use (private, shared, commercial)
☐ Note approximate age of pool and equipment
☐ Identify water source (municipal, well, other)
☐ Check for required permits or visible approvals (if applicable)

Safety Barriers and Access

☐ Inspect perimeter fencing (minimum 48 in height measured on the side away from the pool, maximum 2 in vertical clearance at bottom over non‑solid surfaces and 4 in over solid surfaces, openings not more than 4 in where applicable, overall stability)^[2]^[3]^[4]
☐ Check gates for self-closing and self-latching function (gates swing away from the pool, self-closing from fully open, latch engages reliably)^[4]^[2]
☐ Verify latch height and accessibility (latch not less than 54 in above grade on the pool side, child safety compliance)^[4]
☐ Inspect for climbable objects within at least 36 in of the barrier on the pool side that could reduce effective 48 in barrier height or allow footholds (e.g., furniture, trees, projections)^[2]^[4]
☐ Check pool covers (manual or automatic) for condition and operation; where used as a safety cover, note if cover appears to be a listed safety cover tested to applicable standards and spans the full pool opening with minimal gaps at the perimeter^[5]^[2]
☐ Verify presence and condition of safety alarms (gate, door, or pool alarms if installed), and note if water-surface or door alarms are present as supplemental protection, not as a substitute for a code-compliant barrier^[5]
☐ Inspect signage (depth markers at appropriate locations, “No Diving” warnings at shallow water, safety rules placards where applicable) and note approximate depth locations where signage is installed^[1]^[5]

Pool Structure and Interior^[1]

☐ Inspect pool shell (cracks, spalling, movement, out-of-plane sections that may affect structural integrity)
☐ Check interior finish (plaster, liner, tile condition; note localized defects versus widespread wear)
☐ Inspect tile line and coping for damage or looseness (gaps, sharp edges, displacement)
☐ Look for signs of leaks (unexplained water loss, soil erosion, staining or efflorescence at and below waterline)
☐ Check expansion joints and sealants (gaps, separation, failed or missing sealant where movement is expected)
☐ Inspect steps, ladders, and handrails (secure mounting, corrosion; note if handrail heights appear generally within typical 34–38 in range above stair nosings where present)^[6]
☐ Verify depth transitions and slope consistency (look for abrupt slope changes, sudden drop-offs, or inconsistent depths relative to markers; reference owner or builder information where available)^[5]

Decking and Surrounding Area^[1]

☐ Inspect deck surface (cracks, settlement, heaving, differential movement that may create trip hazards)
☐ Check drainage away from pool (ponding or runoff issues; observe whether surface slopes generally direct water away from the pool and structures)
☐ Evaluate slip resistance of walking surfaces, especially within approximately 36–48 in of the pool edge where frequent wet-foot traffic occurs^[4]
☐ Inspect joints and expansion gaps (excessive widening, missing sealant, displacement that could catch toes or wheels)
☐ Check for proper bonding/grounding of metal components within the bonding grid area around the pool (typically within 3–5 ft of the water edge; look for bonding connections at rails, ladders, diving boards, and equipment)^[5]
☐ Look for vegetation or roots within several feet of the pool or deck that may be impacting structure, decking, or underground components

Circulation System^[1]

☐ Identify pump type and condition (single-speed, two-speed, variable-speed; corrosion, noise, age/labeling)
☐ Verify pump operation (unusual noise, vibration, leaks, priming issues)
☐ Inspect filter type (sand, cartridge, DE) and condition (tank corrosion, leaks, pressure rating labels)
☐ Check pressure gauges for functionality (reads above zero while system operating, responds to backwashing or cleaning)
☐ Inspect valves and plumbing for leaks or damage (broken handles, weeping joints, apparent repairs)
☐ Verify proper suction and return flow at typical operating speed (weak flow, air entrainment, cavitation)
☐ Check skimmers (weirs, baskets, condition; note water level generally around skimmer mid-height under normal operation)
☐ Inspect main drains (covers secure and appear compliant with anti-entrapment standards; note if multiple drains are present and spaced apart rather than a single suction point)^[5]

Electrical System^[1]

☐ Inspect visible wiring for damage, improper installation, or non-listed components within the pool and equipment area
☐ Verify GFCI protection for outlets and equipment serving the pool area where accessible (test/reset buttons, labeling)^[5]
☐ Check bonding of pool components (ladders, rails, diving board bases, equipment housings) within the bonding zone, typically within several feet of the water edge^[5]
☐ Inspect pool light(s) for operation and sealing (evidence of water intrusion, cracked lenses, loose niches)
☐ Verify electrical panel labeling and accessibility for pool-related circuits (clear identification of pump, heater, lights, and accessories)
☐ Look for extension cords or unsafe temporary wiring in the pool area (cords across walkways, non-weather-rated devices near water)

Heating System (if present)^[1]

☐ Identify heater type (gas, electric resistance, heat pump, solar)
☐ Inspect heater condition (corrosion, leaks, damaged casing, blocked or improperly terminated venting for fuel-fired units)
☐ Verify heater operation (responds to call for heat, cycles on, basic function)
☐ Check for proper clearances and ventilation at heaters per manufacturer labels where visible (adequate space around unit, no obvious combustibles crowding)^[5]
☐ Inspect connections and shutoff valves (gas shutoff location, electrical disconnect within line-of-sight where present, evidence of leakage or corrosion)

Water Quality and Condition^[1]

☐ Observe water clarity (main drain or deepest point visibly discernible from deck edge)
☐ Check for debris, algae, or discoloration at surface and in corners/steps
☐ Note water level (generally around mid-skimmer opening under normal operation)
☐ Identify unusual odors that may indicate chemical imbalance (strong chlorine, “musty” smell, other off-odors)
☐ Check for staining or scaling on surfaces (mineral deposits, metal staining, discoloration at waterline and hardware)

Accessories and Features^[1]

☐ Inspect diving board (secure mounting, no excessive flex or cracks, non-slip surface, hardware free of significant corrosion)^[5]
☐ Check slides (structure, water supply where applicable, anchorage, stability; note that ladder/steps appear to have reasonably uniform rise/run and graspable supports)
☐ Inspect waterfalls, fountains, or water features (secure mounting, no obvious leaks at penetrations or equipment, safe routing of piping and wiring)
☐ Verify operation of automation systems (timers, controls, actuators) for scheduled circulation and features
☐ Check pool cover equipment (rollers, tracks, motors, anchors) for secure installation and function; note that cover fully spans pool and minimizes openings when deployed^[2]

Spa/Hot Tub (if applicable)^[1]

☐ Inspect spa structure and interior finish (cracks, delamination, blistering)
☐ Verify heater and temperature controls (setpoint adjustment, limiter presence; observe that controls are located to minimize user contact with energized components)
☐ Check jet operation and air controls (blocked jets, uneven flow, noisy air inlets)
☐ Inspect suction covers and safety compliance (secured covers, anti-entrapment design, no broken grates)^[5]
☐ Evaluate water clarity and condition similar to pool (visibility of suction fittings and surfaces, staining or scaling)

Winterization/Seasonal Components (if applicable)^[1]

☐ Inspect winter cover condition and anchors (tears, fraying, loose or missing anchors, trip hazards where anchors protrude)
☐ Check for proper winterization of plumbing and equipment where observable (opened drain plugs, air or antifreeze evidence, equipment drained)
☐ Look for freeze damage or cracked components (filter housings, pumps, exposed pipe sections, valves)

Documentation and Final Notes^[1]

☐ Record all observed defects and safety concerns
☐ Take representative photos of key components, including overall barrier layout and representative fence/gate conditions
☐ Note inaccessible or not inspected areas (including any barriers, gates, or equipment not safely reachable)
☐ Provide maintenance recommendations appropriate to observed conditions
☐ Recommend further evaluation by specialist if needed (pool contractor, electrician, structural engineer, etc.)

Note: This checklist references International Swimming Pool and Spa Code (ISPSC) style barrier dimensions for typical residential installations (for example, 48 in minimum barrier height, 2–4 in maximum bottom clearance depending on surface, 4 in maximum opening, and 54 in minimum latch height). Actual jurisdictional requirements may vary; verification with local codes and authorities is recommended for every inspection.^[3]^[2]^[4]
