Manchester FAQ
Do I need a fence around my pool?
Yes, Manchester requires a barrier at least 4 feet high with self-closing, self-latching gates around all residential swimming pools.
Does my above-ground pool need fencing?
If the pool sides are at least 4 feet and non-climbable with a lockable ladder, this may satisfy barrier requirements. Check Manchester codes.
Nashua FAQ
Can I use my existing 4-foot fence as my pool barrier in Nashua?
Yes, if it is at least 48 inches above grade on the side facing away from the pool (ISPSC Sec. 305.2.1), has no openings allowing passage of a 4-inch sphere (Sec. 305.3), has no more than a 2-inch gap from grade (Sec. 305.2.4), and all gates open outward, are self-closing, and self-latching (Sec. 305.5).
Where does the pool gate latch go?
Per ISPSC Sec. 305.5, if the release mechanism is below 54 inches above grade, it must be 'on the pool or spa side of the gate not less than 3 inches below the top of the gate, and the gate and barrier shall have no opening greater than 1/2 inch within 18 inches of the release mechanism.' This makes the latch inaccessible to a child reaching over the gate.
Does Nashua add stricter pool fencing rules?
No. Nashua's NRO Sec. 105-25 adopts the ISPSC under the New Hampshire State Building Code (RSA 155-A) and applies the state-adopted edition (2021 ISPSC effective December 31, 2024 under HB 1681). The 48-inch standard and 4-inch sphere rule control.
