Manchester FAQ

Nashua FAQ
Do I need a door alarm if my back door opens to the pool?
If a dwelling wall serves as part of the pool barrier, ISPSC Sec. 305.6 (adopted by NRO Sec. 105-25) requires the door with direct access to be equipped with an alarm conforming to UL 2017, or the pool must have an ASTM F1346 safety cover, or the door must be self-closing and self-latching with a release at least 54 inches above the floor.
Are residential and public pool rules the same?
No. NRO Sec. 105-26.B states: 'Public Swimming Pools and Spas shall also be regulated by NH DES Public Pool and Spa Program in accordance with RSA 485-A:26 and Env-Wq 1100 Public Bathing Place.' Public pools must meet additional standards including federal VGBA drain-cover compliance and NH DES water quality and licensing requirements.
Who do I appeal a Building Official decision to?
Per NRO Sec. 105-26.F, 'Appeals to the decision of the Building Official shall be in accordance with the processes established in NRO Section 105-5.' This routes pool and spa code appeals through Nashua's standard building-code appeal process.
