Pool Fence Requirements in New Hampshire
NH law requires a barrier around residential swimming pools. Here's exactly what the code says and how to pass inspection the first time.
Why NH Requires Pool Fencing
New Hampshire RSA 485-A:22 requires a barrier around all outdoor residential swimming pools, hot tubs, and spas that hold water deeper than 24 inches. The intent is drowning prevention, particularly for children under 5.
Your town's building inspector will verify compliance before issuing a certificate of occupancy for a new pool, and many towns also inspect existing pools when a property changes hands or a fence permit is pulled.

Best Fence Materials for Pool Areas
Not every fence material works well around a pool. Chlorine splash, constant moisture, and the need for visibility all factor into the right choice.
Aluminum (Recommended)
Rust-proof, powder-coated, meets code out of the box. Allows visibility to the pool from inside the house. Most popular choice for NH pool enclosures. Starting at $30/linear foot installed.
Vinyl Privacy
Good for full privacy around the pool area. Resistant to moisture and chlorine. Blocks visibility, which some homeowners prefer. Starting at $35/linear foot installed.
Chain Link with Privacy Slats
Budget-friendly option that meets code. Add privacy slats for screening. Not the most attractive option but functional and affordable. Starting at $15/linear foot installed.
Wood (With Caveats)
Pressure-treated wood works but requires regular sealing in pool environments. Picket spacing must not exceed 4 inches. Starting at $25/linear foot installed.
Common Inspection Failures
Most pool fence inspections fail for preventable reasons. The top issues we see:
- Gate latch on the wrong side — the latch must be on the pool side, at least 54 inches from grade
- Gate doesn't self-close — spring hinges must close the gate from any open position
- Bottom gap too large — more than 2 inches of clearance under the fence fails code
- Climbable objects within 36 inches — planters, AC units, deck furniture near the fence create footholds
- House door without alarm — if the house wall is part of the barrier, any door opening to the pool area needs an alarm
We check all of these during installation and catch issues before the inspector arrives.
Above-Ground Pool Requirements
Above-ground pools with walls at least 48 inches tall may use the pool wall itself as part of the barrier, but the ladder or entry point must still be gated or removable. If the pool wall is shorter than 48 inches, you need a separate fence that meets the full barrier code.
Many towns treat above-ground pools identically to in-ground pools for barrier purposes. Check with your local building department.
